Embodiment

The invention will be further described below in conjunction with accompanying drawing.

As shown in Figure 1, the refrigerator that possesses digital television function among the present invention, comprise processor and the memory module that is connected with processor, peripheral interface module, human-computer interaction module, power management module and control Executive Module, also comprise CMMB (Mobile Multimedia Broadcasting) module, described CMMB module connection processing device.

Processor is the refrigerator host CPU, can adopt Changhong Apollo multimedia process chip.It is used for, and control command sends, scheduling, decoding and the peripheral equipment management etc. of data flow.Wherein control command is meant behind the response software program dependent instruction in the instruction set is sent, and instruction set mainly comprises the associated instruction set of memory reference instruction, data move, data processing instructions, branch instruction, coprocessor instruction, status register transfer instruction and exception handling instruction etc. and CMMB signal receiving module; The scheduling of data flow mainly be to audio, video data reception, write, read scheduling; Decoding is that the audio, video data bag is decoded into image and sound; Peripheral hardware comprises equipment such as USB, SD, LCD, touch-screen, button (button), MIC, loudspeaker.

The CMMB module, the mobile digital multi-media broadcast signal that is used for receiving is converted to the CMMB audio and video data streams; The CMMB module comprises antenna, CMMB Receiver Module, CMMB baseband processing module, described CMMB Receiver Module, be used to receive mobile digital multi-media broadcast signal, to receiving to such an extent that mobile digital multi-media broadcast signal carries out frequency down-converts, mould/the number conversion of signal, and the conversion of signals after the conversion become digital same-phase phase shift IQ signal, then digital same-phase phase shift IQ signal is sent to the CMMB baseband processing module; Described CMMB baseband processing module is used to receive described IQ signal, and the IQ signal that receives is carried out obtaining menu data stream after the demodulation; Data flow by data/address bus, is placed in the buffering area of memory module internal memory under the control of processor, decodes then and the file reorganization, delivers to human-computer interaction module after reorganization is finished and shows.

Human-computer interaction module, be used to realize that user's input operation processing and output show, the user can realize the operation of touch-screen, button, MIC by human-computer interaction module, the demonstration of control menu, the playing programs of Digital Television, volume are regulated, audio frequency and video are play and the setting of refrigerator parameter, the mutual message just recorded between the kinsfolk; Human-computer interaction module comprises equipment such as LCD display and/or touch-screen, button, MIC.

Memory module is used for writing, read and storing of data; Memory module comprises internal memory RAM and NAND FLASH RAM; Internal memory RAM is used for writing of metadata cache and reads processing, and NAND FLASH RAM realizes the storage of audio, video data, food information, recipe storage, embedded software storage etc.Described NAND FLASH RAM memory is divided into four storage areas, first's storage embedded software and system version data etc., second portion storage recipe data; Third part storage food information; The 4th part storage audio, video data.First can instruct in manufacturer according to the software of manufacturer's issue and upgrade after sale to the doorstep; Second and third, four parts all can upgrade voluntarily according to user preferences.

Peripheral interface module is used for the connection of ancillary equipment, sticks into the renewal of line number word TV CAS deciphering or data such as common SD card menu, audio frequency and video by the CA that patches in the peripheral SD/MMC interface; Peripheral interface module comprises common interfaces such as USB, SD, network, bluetooth, makes the user to upgrade data such as menu, audio frequency and video by multiple peripheral hardware, satisfies the demand that the user changes stored information according to the personal like.Carry out in the digital television CA S decrypting process, after processor receives the CMMB program stream of encryption, be sent in the CA kilocalorie that patches in the MircoSD deck by public SD/MMC interface.CA kilocalorie descrambling from EMM and ECM goes out program key, and is clear stream with program key with the deciphering of the code stream of scrambling, passes processor back and reads and play; Or receive the CMMB program stream of encryption at processor after, be sent in the CA lesser calorie that patches in the MircoSD deck by public SD/MMC interface.CA lesser calorie descrambling from EMM and ECM goes out program key, and sends back in this machine of reception, receives this machine and is clear stream and plays with the code stream deciphering of this program key with scrambling.

The control Executive Module is used to realize the control of refrigerator cold-storage and cryogenic temperature, is controlled by serial communication by processor when the user resets temperature, realizes digitlization design temperature and real time temperature Presentation Function.

Power management module is made of power supply AC/DC change-over circuit, realize with the 220V alternating current be converted into the required 5V of system, direct currents such as 3.3V, 1.8V use for system.

As shown in Figure 2, the invention also discloses the method that on the described refrigerator that possesses digital television function, realizes menu updating, specifically comprise the steps:

1. carry out regional frequency search; Carry out regional frequency search by processor control CMMB module;

2.CMMB module is carried out demodulation to the CMMB signal that receives, and obtains a plurality of multiplexed frames;

3. processor is resolved described multiplexed frame by software program and is obtained all kinds of control information tables of CMMB Digital Television, comprise the basic description list of network information table NIT, ESG, continue period service duplexing configuration list CMCT, continue service allocation list CSCT, short-period service duplexing configuration list SMCT, short time service allocation table SSCT etc., and on the touch-screen of human-computer interaction module, present program ESG information for the user by software program;

4. the user selects data broadcast service menu updating menu by the touch-screen/button of human-computer interaction module, processor sends dependent instruction according to selected menu (customizing certain menu or default system menu) and carries out corresponding time slot selection to the CMMB signaling module, carries out the respective digital television broadcast data and receives;

5. controller is resolved described timeslot multiplex frame by software program and is obtained CMMB data broadcast of digital TV data flow, is the menu file by decoding reorganization blocks of files, and stores second storage area of memory module into.

6. the user can inquire the menu of new storage by the touch-screen/button of human-computer interaction module, and carries out dish cooking according to new menu.

Receive after (CA encryptions) implement in condition, can by peripheral interface module insertion SD card of the present invention or before dispatching from the factory built-in CA SMD decryption chip watch CMMB encoded channel and data broadcasting.

By the operation of software, this refrigerator can realize also that each refrigeration, the visualization digital temperature control of refrigerating chamber, temperature show in real time, the demonstration of literal picture and the audio frequency and video playing function of menu inquiry, vegetable Combination Design, food materials counting statistics, vegetable manufacture method.
