Description

TITLE

Service automat TECHNICAL AREA

The invention relates to a service with a display device, such as vending machines and ATMs. In particular, the invention relates to the generation of data for display on such a display device.

STATE OF THE ART

Service machines, such as vending machines and cash machines, can be used for a variety of applications. These include, among other things, the deposit and withdrawal of cash, the making of transfers and numerous other financial transactions related services. For this purpose, such service machines have a plurality of components. Such components include input and output modules, magnetic card, chip card and transponder reader modules, PIN input pads, receipt printers, displays or monitors, various keys and keypads, touch screens, camera, scanner, signal lights and the like.

The control of the service machines including the control of the various components can be taken over by a PC-like computer platform with an operating system, which can be a common operating system such as Windows or Linux. Even if the basic functions are comparable, the control for the internal functioning of the components may vary depending on the manufacturer and type of service machine. For an application software of the service provider operator, a software interface can be provided which provides a standardized interface independent of the manufacturer of the service machine for the application software of the operator. In this way, an application or application software of the service provider or the operator of the service machine largely independent and without major adjustments on machines from different manufacturers, that is on different hardware platforms, run. Both the hardware and the software components are usually protected against unauthorized manipulation. For example, with ATMs, the risk of unauthorized deposit or withdrawal or theft of personal and / or security-critical data can be minimized. However, the expense of creating a secure application software and its testing and certification is considerable. Even with minor changes to the software, there is always a considerable effort to reconsider. As a rule, machines are in use for many years, so that a service machine operator often has several machines of different device generations or even of different manufacturers in operation. In order to keep the effort for the maintenance of the application software small despite technical differences of the various devices, it is desirable to be able to operate one and the same application software on different machines. In addition, various additional device-specific instructions and signals can be used in various devices, for example, to identify the individual machine components, which are to be considered or used by the customer in the course of an operation at specific times. These include, for example, flashing lights, information arrows or illuminated letters next to the card reader, the pin pad, the cash dispenser or the receipt printer, in order to indicate to the user where the next operator action is to be performed on the machine and how this is to be carried out. These light signals can be activated by the application software depending on the next operator action expected by the user. Added to this are simple instructions and symbolic, greatly simplified displays on the screen. Such on-screen instructions are usually very general because the same output or instruction can be used for or provided for a number of different types of automata. The indications and signals are activated by the application software either via standardized, device-independent interfaces as a function of the performed business case or automatically with the activation of a specific machine component to which the respective note is assigned.

It would be desirable if, instead of simple symbols, flashing luminaires or arrows, the user had clear, realistic and suitable mappings and video sequences of the respective automaton components and the operator actions to be performed thereon could be displayed on the screen depending on the respective operating situation or the current business process. However, the output of such automatic representations on the screen would require a similar automatic design or automatic configuration of the application software. Contrary to this, one aim of the ATM operators is to design the application software uniformly and not unnecessarily complex, since a large variance or frequency of change considerably increases the expenditure for the required checks and approval processes with regard to the security and reliability as well as the maintainability of the software. Based on security considerations, the application software is designed so that it fully and exclusively uses the fully integrated display in the machine and other software components can not make screen outputs that could mask and distort the output of the application soft- ware. Conventional overlay techniques such as simple virtual output windows are therefore prohibited.

One conceivable option would be to display the machine-specific, realistic images and video sequences on a separate screen that is completely separate from the output screen of the application software. The application software activates or deactivates the individual components of the ATM by means of function calls via a software interface provided by the basic software or the machine-specific software of the automatic machine. The basic software outputs the assigned realistic, machine-specific instructions, images and video sequences on the second, independent screen, matching the activated components or the respective process or operating step. The provision of a second display only for the automatic output of operating instructions, which is controlled exclusively by the base software of the machine, while conceivable, but uneconomical and represents a limitation of the design possibilities in the design of the service machine. DISCLOSURE OF THE INVENTION

It is an object of the present invention to provide a service machine with a display device and a device for outputting display data to the display device, which enables an improved and reliable display of display data based on different applications on which a display device. Another object is to provide a corresponding method. The tasks are provided by a service automat with the

Characteristics of claim 1 and a method having the features of claim 14 solved.

Accordingly, a service machine with a display device and a device for outputting display data to the display device is proposed, wherein the display device has at least a first display area and a second display area. The device comprises the following features: a first input adapted to receive first data, a second input adapted to receive second data, a mixing unit adapted to supply the first data and the second data an intermediate signal to be combined such that the first data area is associated with the first display area and the second data area, the second display area having predefined properties corresponding to predefined characteristics of the second data, a graphics processing device capable of processing the intermediate signal and generating an output digital video signal based on the intermediate signal, and an output configured to output the output digital video signal to the display device. The first data and the second data are each suitable for display on each of a separate, standardized display device (each with predetermined first and second screen resolution) and set up. The mixing unit is configured to combine the first data and the second data into a common intermediate signal such that image information both the first and second data, after processing the intermediate signal and generating a digital output video signal by the graphics processing device, are simultaneously displayed on a shared, standardized display device (with a predetermined third screen resolution). In this case, the first display area can also have predefined properties that correspond to predefined properties of the first data. The image data of at least the second data are in this case determined by a software program, that is to say the application software, which is designed for exclusive, sole use of a display device.

Under service machine in particular sales and ATM are understood. For example, the service bureau may be an ATM, ticket vending machine, a vending machine, an account information terminal, a lottery terminal, a package parcel machine for sending or receiving parcels, a check-in terminal, or any other type of service or cash dispenser. Each type of automaton may have a display device to display any data. The data to be displayed is supplied to the display device by a display data output device. The display device may be, for example, a screen or monitor having a first display area and a second display area.

By the device for outputting display data, it is possible to provide the service machine with a display, wherein on a common single physical display or a common display device first display data (for example application data of the service provider operator) and second display data (for example, machine-specific instructions) are displayed. The second display area can be used for the second data as an exclusively assigned display, to which a special resolution or other special, predefined settings or also exclusive image memories and software interfaces or own virtual display areas (windows) are assigned. This special resolution can be predetermined, for example, by an application or application software of a service-provider operator. The rest of the display area, which is referred to here as the first display area, is not predefined by the application software in appearance and can be used independently of this application software by other signals or data, such as the first data. In this way, the application software can be operated without adaptation to the actual size of the display. At the same time, the remaining area of the display is available for the output of image information by other software components.

For example, the first data and the second data may be received as a first signal and a second signal. The first signal and the second signal may have the first (display) data and the second (display) data, respectively, containing display information. In this case, the second display area has predefined properties, wherein the mixing unit is set up in such a way that it adjusts or at least provides the expected resolution of the second display area or other properties during the generation of the intermediate signal. The mixing unit may also be arranged to rotate the second data or the associated display, that is to change the orientation, for example in order to ensure that the image data contained in the second data match the native drive direction of the display device , In one embodiment, the second signal or the second data contained in the second signal may already have the predefined properties of the second display region.

Alternatively or additionally, the graphics processing device may be configured to rotate the digital output video signal or the associated display, or to generate a rotated digital output video signal when processing the intermediate signal. This may be necessary if the display device is installed and operated in portrait format, but the image data for the second display area correspond to a landscape image or are provided by the application software for a display device in landscape format. The first display area and the second display area may be divided in various ways. Thus, the second display area may be included in the first display area or vice versa. This can be called picture-in-picture (bite) or picture-in-picture (PiP). In another embodiment, the first display area and the second display area may be the same be large and arranged one above the other or side by side. This type of presentation can also be referred to as split-screen. Any other type of arrangement or division is also possible. The first data and the second data, which are also referred to herein as first display data and second display data respectively, may include display information or pixel information for the first and the second display area, respectively. The display information includes, among other information, display content or display style, resolution, orientation, color, brightness, etc.

In addition to the display data, the first data and the second data may also contain further information regarding the corresponding application software. The first data may correspond to a service machine specific application or display data. The second data may correspond to an operator-specific application or display data.

Operator-specific application in this context refers to an application or application or application software that is provided by the operator of the service machine, such as a bank. The operator-specific application software, for example, depicts the various service processes of the machine offered by the operator; in the case of a banking service machine, for example, the payment and withdrawal of cash, the making of transfers, the checking of the account balance or the printing of account statements.

By contrast, the machine-specific basic software is adapted to the respective embodiment, technical equipment, the type and the manufacturer of the machine and in turn provides the application software with a largely platform-independent interface for the use of the respective machine components. Service machine-specific application, machine-specific basic software or application software in this context refers to an application or application software provided by the manufacturer of the service machine, for example in the manufacture or delivery of the service machine. By the automatic application For example, additional information may be presented in addition to the operator-specific application. This information includes, for example, machine-specific animations, video sequences or images, arrows, camera images, commercials, hints for auto-specific settings, including personal adjustments or improved usability such as height adjustment of the screen or the second display area. For example, camera images that can be displayed on the first display area allow a user to see if someone is behind them. In this way, security when entering security-relevant data such as PINs can be improved. The embodiment of a service machine according to the invention allows information to be output simultaneously from both the machine-specific basic software and the operator-specific application software on a single shared display device, even if the configuration of the operator-specific application software actually requires an exclusively associated display device or an existing display device of the operator-specific one Application software is normally used exclusively.

A graphics processing device is understood herein to be a device having graphics card functionality. The graphics processing device may include an operating system as well as drivers. An interface compliant with the DVI standard (Digital Video Interface) or HDMI standard may be provided between the graphics processing device and the display device. In this case, the output video signal may include analog and digital data. The graphics processing device may be, for example, a structural unit such as a printed circuit board or a chip, in particular a microchip.

The graphics processing device may be configured to process the received data, that is the received intermediate signal, in particular the resolution of the received display data in the intermediate signal. In this way it can be ensured that the operator-specific display data with the predefined properties can be processed by the mixing unit and displayed by the graphics processing device. In one embodiment, the mixing unit is configured to prioritize the second data over the first data.

The mixing unit, for example, as a possible predefined setting, regardless of the application and basic software operated on the machine, ensures that the second display area is always completely visible and can not be overwritten by parts of the first display area. Thus, according to this embodiment, it can be ensured that the second data is displayed in each case, whereas the first data need not be displayed in each case and may be superimposed on the second data on a case by case basis. In this way, display data contained in the second data can be represented with highest (or at least high) priority.

Since the second data can contain display data that is assigned to an application software of a bank or another machine operator, it may be necessary to always display these - depending on their relevance. On the other hand, the first data may contain display data which are only specific to the machine, for example contain operating instructions which do not have to be displayed under all circumstances, in particular not completely. This may be important, for example, in terms of inhibiting software manipulations, such as fingering transactions that are not actually taking place, spying on access data, or the like.

Since the device per se is machine-specific and also the position on the display at which the image corresponding to the second data is displayed in accordance with the digital output video signal, the automatic specific base software or the first data may also be adapted such that In the case of an overlay, they only use those parts of the first display area which are not superimposed by the second display area, so that nevertheless all relevant information can be recorded on the screen. The automatic software or basic software is thus designed so that it does not use certain parts of the first display area which are superposed by the second display area. In this case, the mixing unit is set up to take into account such an overlay when generating the intermediate signal. Thus, the intermediate signal already has a combination of the first data and the second data, which are subsequently converted in the graphics processing apparatus to a digital output video signal. This output digital video signal contains information for the first display area and the second display area.

The graphics processing device, in one embodiment, may be an SD graphics card with a 3D support. Such a graphics card can control the overlay and visibility of graphics elements based on a depth coordinate (z-coordinate). Accordingly, the mixing unit may be arranged to assign different depth coordinates and positions to the first data and the second data. In this case, the intermediate signal may include the first data and the second data with additional information. The graphics processing device can be set up accordingly to evaluate the additional information and to provide for display on the display device, in which case, for example, the second display area overlays the first display area. In a further embodiment, the first input and the second input each have an interface to a self-running operating system.

Such interfaces may be standardized interfaces via which a simple connection to a computer operating system designed essentially in a hardware-independent manner can take place. For example, the first input may be part of a first operating system and the second input may be part of a second operating system. The second input may provide basic operating system functionality compatible with a self-powered graphics processing device. That is, the second input provides compatibility with a standalone video card or virtual video card.

In another embodiment, at least one of the two operating systems is executed in a virtual machine. According to this embodiment, the device may be implemented on a hardware platform, or a computer or personal computer. One of the two operating systems can be executed directly on this hardware platform. The second operating system can run as a virtual machine or a virtual PC on the hardware platform next to the other operating system.

In a further embodiment, the device comprises a first driver unit arranged between the first input and the mixing unit and a second driver unit arranged between the second input and the mixing unit, wherein the first driver unit is arranged to store the first data and to forward the processed first data to the mixing unit, and wherein the second drive unit is adapted to process the second data and to forward the processed second data to the mixing unit.

Since the driver units already perform a first processing of the data, the mixing unit can easily combine the processed first data and the processed second data without requiring complicated computation operations. For example, the driver units can already process the first data and the second data, so that the mixing unit only has to perform a merging or superposition of the data. Processing the first data and the second data may include translating the first data and the second data into pixel data. The driver units may further interfere with an operating system. As already explained above, the first input and the second input can represent interfaces to one operating system each. These interfaces can also be represented by the driver units. In another embodiment, the apparatus includes a driver device configured to receive the intermediate signal and to drive the graphics processing device based on the intermediate signal. Such a driver device may serve as an interface between the mixing unit and the graphics processing device. The driver device may forward the intermediate signal to the graphics processing device such that it receives a conditioned intermediate signal that can be processed in a simple manner. For example, the driver device can forward to the graphics processing device further information that is required for display on the display device. For example, this information may include information about alignment, resolution, or the like. In another embodiment, the first display area has a plurality of sub-display areas, and the first data has display data for the plurality of sub-display areas.

According to this embodiment, in addition to the second display area, a plurality of further, in particular virtual, display areas can be defined. The first display area may thus have a plurality of sub-display areas. These sub-display areas can be used for various displays that need not be related. In a further embodiment, the first data comprises a plurality of individual data signals each associated with one of the plurality of sub-display regions.

According to this embodiment, the first input may receive a plurality of individual data signals each having data for a sub-display area. These data signals can be received consecutively. It is also possible that a single data signal is received having information relating to each of the plurality of sub-display areas. In a further embodiment, the apparatus has a third input adapted to receive third data, wherein the mixing unit is arranged to combine the first data, the second data and the third data into an intermediate signal such that the third data a third display area is associated with the display device, the third display area being predefined. has nierte properties that correspond to predefined properties of the third data.

The third data can be entered, for example, directly via a USB interface, via which a certified display and keyboard communication can then proceed. The third data may include, for example, data for a line display of a payment module. Such a line display can be emulated by the mixing unit and the characters provided for output can be passed on or output by the mixing unit to the graphics processing device or another graphics processing device. The graphics processing device or the further graphics processing device may then display the third data at a designated location of the common screen or the display device. According to this embodiment, the display device has a third display area in which the display data included in the third data can be displayed. The third data, like the second data, has fixed predefined properties corresponding to characteristics of the third display area. In this way, the device or software that provides the third data can be offered the third display area with specified properties.

In a further embodiment, the mixing unit is set up to prioritize the second data and the third data with respect to the first data.

According to this embodiment, the second data and the third data are always displayed on the display device. If the first data would be displayed on areas of the display device on which the second data or the third data would also be displayed, the first data will be neglected with respect to the others. That is, in such a case, the image information of the first data is not displayed on these areas, but the image information of the second data or the image information of the third data is displayed. In an alternative embodiment, a cascade of prioritizations is provided. In this case, a highest (or at least high) priority can be assigned to the second data and the third data. In particular, the third data may be assigned the highest priority, the second data an underlying priority, and the first data the lowest priority. In this way, it can be ensured that data with the highest relevance, which are assigned to the third data, are displayed in each case, that data, which have a lower relevance than the third data, and that are associated with the second data, with a lower but still high priority, and data having the least relevance and associated with the first data are presented with the lowest priority.

In a further embodiment, the third data is encrypted. Encryption of the third data may provide protection against unauthorized access to this data. In this way, it can be ensured that security-relevant data contained in the third data can not be accessed without authorization. In particular, encryption of the third data may be some type of cryptographic encoding. In this case, for example, a symmetric cryptographic coding or an asymmetric cryptographic coding come into question.

In a further embodiment, the mixing unit is configured to receive position information that is indicative of a position and / or orientation of the first display area and / or the second display area on the display device.

According to this embodiment, the mixing unit may receive position information, for example, as a position signal indicating a position of the first display area and / or the second display area on the second display device. This position information may further indicate a position of the third display area, if any. In addition to the position, the position information may also indicate an orientation, such as portrait or landscape, or other information. The position information can be used as a position signal via an external input, for example. For example, via a USB interface, are received. Alternatively or additionally, the first data or the second data, if present possibly also the third data, may contain the position information. For example, the position information can be input externally by a user, for example, a machine operator. The position can be set by parameters, which are then contained in the position information.

Alternatively or additionally, the positions can be determined according to design and ergonomic criteria already during the production process. In this case, the machine operator uses the application software to create a platform-independent interface that only provides general basic functionalities that are required for mapping the application software, whereby the positions of the application software have already been defined. In a further embodiment, the mixing unit is configured to store position information that is indicative of a position and / or orientation of the first display area and / or the second display area on the display device. According to this embodiment, the position information can be fixedly stored in the mixing unit. For example, if the position information is received by an external signal, that position information may be stored until new position information is input via a new external signal. The mixing unit may have a memory for storing the position information.

In a further embodiment, the mixing unit is set up to replace the first data at least partially by the second data when generating the intermediate signal.

According to this embodiment, the first data may be at least partially overwritten by the second data in generating the intermediate signal. As a result, an overlay of the first display area is indirectly achieved by the second display area. For this, bits of the first data corresponding to the first are overwritten by bits of the second data associated with the second display area. In other words, in the image data stream of the first data, pixel information on screen coordinates, or coordinates or positions of the display device superimposed on the second data are replaced by the corresponding image information or pixel information of the second data. The pixel information at non-superimposed display device coordinates will persist and may be present in the intermediate 1: 1 signal. In a further embodiment, the mixing unit is configured to replace the first data with a dummy signal when combining the first data and the second data if the first data is missing or contains no display data. If the device recognizes, for example by means of the mixing unit, that the first data does not contain display data, the device can replace the first data with a dummy signal. The dumb signal may correspond to a signal containing only pixel information regarding black pixels. The generation of such a black video signal, for example a black HD (High Definition) stream, can be performed in the mixing unit. Here, in the mixing unit, pixel information is added to the intermediate signal with respect to black pixels which are then included in the intermediate signal.

In a further embodiment, the device is configured to switch off the display device if the second data is missing or contains no display data.

Unless data is received for the second display area, according to this embodiment, the display device can be turned off. Since the second data represent operator-specific data, according to this embodiment, the entire display device can be switched off, provided that no operator-specific data can be displayed. In this way, the security of the service machine can be increased because the display device only works when an application software of the operator sends data to the device. As a result, it can be ruled out, in particular, that manipulations on the machine-specific application are carried out, which would then display simulated second data on the display device. In a further embodiment, the mixing unit and / or the graphics processing device is designed as a Connputerprogrannnnprodukt. The computer program product is set up to run on a program-controlled device. The computer program product such as a computer program means can for example be provided or supplied as a storage medium, such as a memory card, USB stick, CD-ROM, DVD or even in the form of a downloadable file from a server in a network. This can be done, for example, in a wireless communication network by the transmission of a corresponding file with the computer program product or the computer program means. In addition, a data carrier with a stored computer program is proposed with commands which form the computer program product when executed on a program-controlled device.

The respective unit, for example the driver units, driver device, mixing unit and graphics processing device, can be implemented in terms of hardware and / or software. In a hardware implementation, the respective unit may be embodied as a device or as part of a device, for example as a computer or as a microprocessor. In a software implementation, the respective unit may be designed as a computer program product, as a function, as a routine, as a stand-alone process, as part of a program code and / or as an executable object. The said respective units may also be implemented in a plurality of separate processor cores within a common integrated circuit or be implemented therein.

In a further aspect, a method for outputting display data to a display device of a service machine is proposed, wherein the display device has at least a first display area and a second display area. The method includes the following steps: receive first data, receiving second data, combining the first data and the second data into an intermediate signal such that the first data area is associated with the first data area and the second data area with the second display area having predefined characteristics that are predefined - Finished properties of the second data correspond, processing the intermediate signal and generating a digital output video signal based on the intermediate signal and outputting the output video signal to the display device.

Although the individual steps of the method are mentioned here in a particular order, the method is not limited to this order. Rather, the steps may vary in order or at least partially performed simultaneously.

The invention is explained in more detail below with reference to the exemplary embodiments given in the schematic figures. Show it:

Fig. 6 is a schematic block diagram of a sixth embodiment of a service machine having a display data output device; and

7 is a schematic flowchart of an example of a method of outputting display data.

In all figures, the same or functionally identical means and devices - unless otherwise indicated - provided with the same reference numerals. FIG. 1 shows a service machine 10 having a display device 108 and a device 100 for outputting display data to the display device 108. In this case, first data 103 are received at a first input 101 of the device 100. The first data 103 may be display data of an application specific to the service machine 10. This can be, for example, control panel information or the like. The device 100 further receives second data 104 at a second input 102. The second data 104 may be received in parallel with the first data 103. The second data 104 may be service-specific application data, which may be bank-specific data, for example.

The device 100 has a mixing unit 105. In the mixing unit 105, the first data 103 and the second data 104 are combined into an intermediate signal 106. When combining the first data 103 and the second data 104, the mixing unit 105 superimposes or overwrites in the intermediate signal 106 parts of the first data 103 by data, for example pixels, of the second data 104.

The apparatus 100 further includes a graphics processing device 107. The intermediate signal 106 is transmitted from the mixing unit 105 to the graphics processing device 107. The graphics processing device 107 processes the Intermediate signal 106 and generates an output digital video signal 110 based on the intermediate signal 106. The device 100 further has an output 109 from which the output video signal 110 is output to the display device 108. The interface between the graphics processing device 107 and the display device 108 may be a DVI (Digital Video Interface) interface.

The digital output video signal 110 is sent to the display device 108 and has both data for the first display area 1 1 1 and the second display area 1 12. The display device 108 has a first display region 1 1 1 and a second display region 1 12. As shown in Fig. 1, the first display area 1 1 1 and the second display area 1 12 can be represented as a picture-in-picture function. In this case, the second display area 1 12 overlaps the first display area 1 1 1. The display areas 1 1 1 and 1 12 can also claim the same size areas of the display device 108, as shown in the following figures. Also, the first display area 1 1 1 may be smaller than the second display area 1 12 and this overlap. The second display area 1 12 has predefined properties that correspond to predefined properties of the second data 104. Such properties include, for example, a standardized screen resolution of 1024x768 (XGA) pixels. In this way, the operator-specific application can be provided with a display area 12 which corresponds to a normalized screen resolution for all applications and for different machines, while the display device 108 actually has a larger display area and resolution of, for example

1920x1080 pixels (HD). In this context, overlapping can be understood as meaning a partial or complete superposition of the first display region 11 1 through the second display region 12, or vice versa.

The mixing unit 105 combines the first data 103 and the second data 104 to the intermediate signal 106 such that the intermediate signal 106 represents a combined signal of the first data 103 and the second data 104. This intermediate signal 106 includes display data for the first display area 1 1 1 and display data for the second display area 1 12. In the graphics processing device 107, this intermediate signal 106 is converted into a digital output video signal 110, which can be processed by the display device 108. FIG. 2 shows another embodiment of a service machine 20 having a device 200 for outputting display data to the display device 108. In this embodiment, the device 200 has a virtual machine 205. The device 200 may be implemented on a hardware platform (not shown). The virtual machine 205 can be implemented on the same hardware platform. The first data 103 and the second data 104 are respectively transferred to a first driver unit 201 and a second driver unit 20. The second driver unit 202 is part of the virtual machine 205.

As shown here, the mixing unit 105 may include a storage device 602. The mixing unit 105 may receive a position signal or position information 601 stored in the memory device 602. The position information 601 may include information on which position the display areas 1 1 1, 1 12 are displayed on the display device 108, as well as information about their orientation or other display information. The position information 601 may be received as an external signal, such as a position signal, or may be included in the first data 103 or the second data 104.

The display device 108 may be, for example, an HD display (High Definition Display) with a dual-channel LVDS interface and a resolution of, for example, 1920 × 1080 pixels. The application software, that is, the second data 104, typically requires a lower resolution than the HD display 108 and generates, for example, screen data contained in the intermediate signal 106 for an XGA graphics resolution of only 1024x768 pixels.

FIG. 7 shows a schematic flow diagram of a method 700 for outputting display data. In a first step 701, first data 103 are received at a first input 101 of a device 100. In a second

Step 702, second data 104 is received at a second input 102 of device 100. Subsequently, the first data 103 and the second data 104 are combined into an intermediate signal 106, so that the first data 103, the first display area 1 1 1 and the second data 104, the second display area 1 12th assigned. The second display area 1 12 has predefined properties that correspond to predefined properties of the second data 104. The combining of the first data 103 and the second data 104 (third step 703) is performed in a mixing unit 105.

The mixing unit 105 passes the intermediate signal 106 to a graphics processing device 107, which then processes the intermediate signal 106 (fourth step 704) and generates an output digital video signal 110 based on the intermediate signal 106 (fifth step 705). After generating 705 of the output digital video signal 110, the output video signal 110 is output to the display device 108 of the service machine 10 in a sixth step 706.

Although the present invention has been described above with reference to the preferred embodiments, it is not limited thereto, but rather modifiable in a variety of ways.
