背景发明领域本发明涉及电视信号处理，更具体地，涉及用来把电视信号的辅助信息与辅助视频输出信号相联系的系统、方法和/或设备。 BACKGROUND Field of the Invention The present invention relates to television signal processing and, more particularly, relates to systems for television signal with auxiliary information auxiliary video output signal associated, methods and / or devices.
背景信息当前的电视机典型地包括辅助输出，允许用户把它连接到一个要利用电视机所接收的电视信号的设备上。 Background information on the current TV typically include an auxiliary output, allowing users to connect it to a TV set on the device you want to use the received television signal. 该设备因此利用电视信号的音频和视频信号。 The device thus using audio and video signals of the television signal. 正如技术上已知的，除了正常的音频和视频信息或被包含在电视信号中的数据以外，电视信号还可包括所谓的辅助信息或数据。 As known in the art, in addition to the normal audio and video information or data contained in a television signal other than the television signal can also include a so-called auxiliary information or data. 重要的辅助信息典型地包括，但不限于，电视文字广播数据、闭路字幕数据、扩展的数据业务(XDS)数据等等。 Important supplementary information typically includes, but not limited to, teletext data, closed caption data, extended data services (XDS) data and the like. 至今，辅助数据要么还没有提供给具有音频和视频数据的辅助输出，要么只零星地提供给具有音频和视频数据的辅助输出。 So far, the auxiliary data is either not yet available to the auxiliary output with audio and video data, or only sporadically available to the auxiliary output with audio and video data.
而且，正如技术上已知的，电视信号的视频部分以信息场的形式被提供，两个场构成一个帧。 And, as known in the art, the video portion of the television signal in the form of the information field is provided, two fields constituting one frame. 在所谓的交织格式(interlaced format)中，第一场被提供到显示器，然后第二场被提供到显示器，该第二场交替地插入在第一场中。 In the so-called interleaved format (interlaced format), the first field is supplied to the display, then the second field is supplied to the display, the second field are alternately inserted in the first field. 在所谓的逐行模式中，两个场被同时(即，逐行地)提供到显示器。 In so-called progressive mode, the two fields are simultaneously (i.e., row by row) provided to the display. 按照惯例，辅助数据被提供在第一和第二场的特定的行中。 By convention, the auxiliary data is provided in a particular row in the first and second fields.
在一种形式中，辅助数据包括或构成所谓的闭路字幕数据。 In one form, or a so-called auxiliary data includes closed caption data. 闭路字幕数据提供电视信号中音频部分的文本，它可显示在显示器上，以帮助听力障碍的人。 Text of the audio portion of a television signal to provide closed captioning data, it can be displayed on the display to help hearing-impaired people. 因为这个信息本身是顺序的，重要的是来自第一场的闭路字幕数据应该在来自第二场的闭路字幕数据之前被呈现。 Because this is the order of the information itself, it is important that the closed caption data from the first field should be presented in the second field of the closed caption data from before. 否则，如果数据不能以正确的次序被提供，显示的文本将是无次序的，没有意义的，因此达不到帮助听力障碍的人的目的。 Otherwise, if the data can not be provided in the correct order, the text displayed will be no order, no meaning, and therefore fail to help hearing-impaired people purposes.
当闭路字幕数据通过使用主显示器的垂直中断被输出到辅助输出端时，在辅助与主场信息之间会有差别。 When the closed caption data by using the vertical main display is interrupted is output to auxiliary output, there will be differences between the auxiliary and home information. 有时，在主输出与辅助输出之间会存在场倒置，造成第一场数据可能输出到第二场和反之亦然的问题。 Sometimes, between the main output and the auxiliary output will exist field inversion, resulting in the first field data may be output to the second field and vice versa problems. 对于电视信号的视频部分，这可能不是问题。 For video portions of the television signal, which may not be a problem. 然而，对于诸如闭路字幕数据或扩展的数据业务(XDS)数据的辅助信息，如果场被改变，即，辅助信息位于不正确的场中，则不能正确地提取闭路字幕和XDS数据。 However, the auxiliary information such as closed caption or extended data services data (XDS) data, if the field is changed, i.e., the auxiliary information is incorrect field, it can not be correctly extracted closed caption data and XDS.
因此，从以上说明可以看到，有需要把来自接收的电视信号的辅助信息(例如，闭路字幕和/或XDS数据)正确地插入到电视信号接收机中的辅助视频信号中。 Therefore, from the above description can be seen, there is a need to auxiliary information (e.g., closed caption and / or XDS data) from the received television signal is properly inserted into the television signal receiver of the auxiliary video signal.
因此，从以上说明还可以看到，有需要使辅助数据与电视信号接收机中的辅助视频输出信号同步。 Therefore, from the above description can also be seen that there is a need to synchronize the auxiliary data with a television signal receiver auxiliary video output signal.

电视信号接收机22把程序指令31存储在存储器32中，这些指令可以由处理电路/逻辑30执行用于操作电视信号接收机22和/或可以由其他部件执行用于操作电视信号接收机22。 The television signal receiver 22 of program instructions 31 stored in the memory 32, these instructions may be processed by circuitry / logic 30 performs a operation of the television signal receiver 22 and / or may be performed by other components for operation of the television signal receiver 22. 按照本发明的原理，程序指令31提供辅助数据与辅助视频输出信号的同步。 In accordance with the principles of the invention, program instructions 31 provide synchronization of video auxiliary data and the auxiliary output signal. 这是通过把辅助视频信号与主视频信号进行相关而完成的。 This is achieved by the auxiliary video signal associated with the main video signal is accomplished. 在一个示例性形式中，这是通过使用主视频中断信号(例如，VBI)完成的。 In an exemplary form, which is interrupted by using the main video signal (e.g., VBI) completed. 具体地，这可以以一个示例性方式通过检测在主视频信号与辅助视频信号之间的场倒置而完成的。 In particular, this may be an exemplary manner by detecting the video signal between the main and auxiliary video signal field and complete inversion. 更具体地，在一个示例性方式中，本发明通过使用主视频信号的垂直中断信号把提取的闭路字幕数据发送到辅助数据输出端42，该垂直中断信号优选地是从主视频信号得出的或就是来自主视频信号的垂直同步或垂直消隐时间间隔信号。 More specifically, in one exemplary embodiment, the present invention is the use of the main video signal by a vertical interrupt signal to send the extracted closed caption data to the secondary data output terminal 42, which is perpendicular to the interrupt signal is preferably derived from the main video signal or from the main video signal is a vertical sync signal or a vertical blanking interval. 有时，主和辅助显示场可以不相同，因为在主和辅助信号之间时钟频率可以不同。 Sometimes, the main and auxiliary display field may not be identical, since the clock frequency between the main and auxiliary signal may be different. 例如，主显示(主视频信号)可以具有包括60Hz、59.94Hz、30Hz、和29.97Hz中间的一个频率。 For example, the main display (main video signal) may have include 60Hz, 59.94Hz, 30Hz, 29.97Hz and an intermediate frequency. 对于主视频信号，这是用于逐行模式的60Hz或59.94Hz，和用于交织模式的30Hz或29.97Hz。 For the main video signal, which is 60Hz or 59.94Hz for progressive mode, and for interleaving mode 30Hz or 29.97Hz. 然而，辅助视频信号多半是29.97Hz的交织模式。 However, most of the auxiliary video signal is 29.97Hz interleaving pattern. 因此，程序指令31提供检验或检测在主视频信号(用于显示器24)与辅助视频信号(用于辅助输出端42)之间是否存在场倒置。 Thus, the program instructions 31 provide the inspection or testing in the main video signal (for the display 24) and the auxiliary video signal (for auxiliary output 42) exists between the field inversion. 这适当地提供辅助数据与辅助视频信号的同步，用于适当地把闭路字幕提供给辅助视频信号输出端。 This is appropriate to provide a synchronized auxiliary data and the auxiliary video signal, the closed captioning for appropriately supplied to the auxiliary video signal output terminal.
具体地，电视信号接收机22检测或确定在中断程序期间在主视频信号与辅助视频信号之间是否存在场倒置。 Specifically, the television signal receiver 22 is detected or determined during the interrupt routine in between the main video signal and the presence or absence of the auxiliary video signal field inversion. 由于闭路字幕数据出现在场之间，中断程序利用主视频信号的垂直同步或垂直消隐信号作为使程序开始的中断。 Due to the presence of closed caption data occurs between the interrupt routine use of the main video signal vertical sync or vertical blanking signal as to make the program interruption began. 另外，电视信号接收机22根据中断程序适当地提供闭路字幕数据到辅助输出端42。 In addition, the television signal receiver 22 to provide closed caption data in accordance with the interrupt program properly to the auxiliary output terminal 42. 在一个形式中，电视信号接收机利用中断程序以便使用主显示中断来检验辅助显示信号(视频信号)相对于主显示信号(主视频信号)的相位。 In one form, the television signal receiver uses the interrupt routine in order to use the main display interrupt to test the secondary display (video signal) with respect to the signal (main video signal) of the phase of the main display. 这个程序典型地在起动频道调谐(频道改变)或闭路字幕“ON”被电视信号接收机22识别后完成。 This procedure is typically tuned after the starting channel (channel change) or closed caption "ON" by the television signal receiver 22 to identify complete. 在另一个形式中，程序在每次遇到垂直中断时完成。 In another form, the program is completed during each encounter vertical interrupted.
现在参照图4，图上显示在按照本发明的原理的电视信号接收机中用于总体上使来自电视信号的辅助数据与辅助视频信号同步的流程图，总的表示为100。 Referring now to Figure 4, is displayed on the map in accordance with the principles of the present invention a television signal receiver for the auxiliary data from the television signal with the auxiliary video signal to synchronize the overall flow diagram, indicated generally as 100. 在方块102，电视信号接收机22接收电视信号11。 At block 102, the television signal receiver 22 receives a television signal 11. 电视信号11包括视频分量14和辅助数据分量16。 11 includes a video component of a television signal and auxiliary data components 14 16. 此后电视信号接收机22在方块104，处理接收的电视信号(即，它的视频分量)，以便得到主视频信号和辅助视频信号。 Thereafter television signal receiver 22 in block 104, processing the received television signal (i.e., its video component), so as to obtain the main video signal and auxiliary video signals. 主视频信号是要以逐行模式或交织模式以及以上述的频率之一提供给电视信号接收机的显示器24。 The main video signal to progressive mode or interleaving mode as well as the frequency of the one provided to the monitor 24 television signal receiver. 辅助视频信号典型地，但不一定，被提供到电视信号接收机22的辅助输出端，典型地以按照上述的两个频率之一的交织模式提供。 The auxiliary video signal is typically, but not necessarily, is supplied to the auxiliary output terminal of the television signal receiver 22, typically in accordance with one of the above two frequency interleaving patterns provided.
在方块106，电视信号接收机处理接收的电视信号(即，辅助数据分量)，以便得到或提取辅助数据(例如，闭路字幕)。 At block 106, the television signal receiver processes the received television signal (i.e., the auxiliary data component), in order to obtain or to extract the auxiliary data (e.g., closed caption). 闭路字幕数据被提供到主视频信号，用于可能的显示，尤其是和辅助视频信号一起用于可能的显示。 Closed caption data is supplied to the main video signal, may be used to display, in particular, and may be used together with the auxiliary video signal is displayed. 然后在方块108，电视信号接收机22把提取的辅助数据与辅助视频信号同步，以便保证辅助数据可以与辅助视频信号和/或以适当的顺序进行显示。 Then at block 108, the television signal receiver 22 extracts auxiliary data synchronized with the auxiliary video signal, in order to ensure that the auxiliary data with the auxiliary video signal and / or displayed in the proper order. 此后，在方块110，电视信号接收机22把与辅助视频信号同步的辅助数据提供到它的辅助输出端。 Thereafter, at block 110, the television signal receiver 22 and the auxiliary video signal is supplied to the auxiliary data synchronized its secondary output terminal.
应当看到，结合图4的流程图描述的程序或方法仅仅是把辅助数据插入和/或与辅助视频信号同步的方法的例子。 It should be noted in connection with Fig. 4 is a flowchart describing a program or method of simply inserting the auxiliary data and / or the auxiliary video signal in synchronization with the examples. 其他的程序、方法和/或它们的版本是可能的和可设想的。 Other procedures, methods, and or their version / is possible and conceivable.
现在参照图5，图上显示按照本发明的一个方面的、确定或检测在被输出到电视信号接收机22的辅助输出端的辅助视频信号与电视信号接收机22的主视频信号之间是否出现场倒置的流程图，尤其是为了同步辅助数据与辅助视频信号，总的表示为50。 Referring now to Figure 5, is indicated on FIG accordance with one aspect of the present invention, is determined or detected between the output to the television signal receiver 22 of the auxiliary output of the auxiliary video signal with the main video signal of the television signal receiver 22 is out of the scene flowchart inverted, in particular in order to synchronize the auxiliary data with the auxiliary video signal, indicated generally at 50. 在方块或步骤52，得到主视频信号的垂直中断。 In block or step 52, the main video signal to obtain a vertical interrupt. 在方块54，电视信号接收机22确定中断是否对于场1的。 At block 54, the television signal receiver 22 determines whether the interrupt for the field 1. 如果中断是对于场1的(用“是”代表是)，然后程序50跳到方块60。 If the interruption is for field 1 (with a "yes" representative), then the program jumps to block 60 50. 因为场1总是在场2之前呈现，场1是开始点，因为闭路字幕数据也是在场1开始的。 Because the field is always present before 2 presents a field 1 is the starting point, because the presence of a closed caption data is started. 在方块60，程序50从辅助视频信号得到场信息。 At block 60, the program 50 obtains the field information from the auxiliary video signal. 在方块62，程序50利用在方块60得到的辅助场信息，以确定主视频信号和辅助视频信号是否在同一个场中。 At block 62, the program 50 using the auxiliary field information obtained at block 60 to determine whether the main video signal and the auxiliary video signal in the same field. 主视频信号在方块54已被确定为是在场1中。 The main video signal is determined to be in the presence of a block 54. 如果主视频信号和辅助视频信号被确定为在同一个场内(用“是”代表是)，则程序进到方块66。 If the main video signal and the auxiliary video signal is determined to be in the same field ("yes" for YES), the program proceeds to block 66. 方块66把电视信号接收机的场倒置模式对于辅助视频信号设置或保持为“关断”。 Block 66 the television signal receiver field inversion mode for the auxiliary video signal is set or kept "off." 此后，程序进到方块68，此时程序结束。 Thereafter, the program proceeds to block 68, then the program ends. 如果在方块62确定主视频信号和辅助视频信号不在同一个场内(用“否”代表否)，则程序进到方块64。 If the main video signal is determined and the auxiliary video signal in block 62 is not in the same field (with "NO" no), the program proceeds to block 64. 在方块64，程序把电视信号接收机的场倒置模式对于辅助视频信号设置或保持为“接通”。 In block 64, the program of the field inversion mode television signal receiver for the auxiliary video signal is set or kept "on." 此后，程序进到方块68，此时程序结束。 Thereafter, the program proceeds to block 68, then the program ends.
在方块54，如果确定在方块52中得到的中断不是用于场1(用“否”代表否)，则程序进到方块56。 At block 54, if it is determined in block 52 an interrupt is not obtained for field 1 (with "NO" no), the program proceeds to block 56. 在方块56，程序确定电视信号接收机22(TSR)对于主视频信号是否为逐行模式。 At block 56, the program determines the television signal receiver 22 (TSR) for the main video signal is a progressive mode. 如果在方块56确定电视信号接收机22不是处在逐行模式(用“否”代表否，表示电视信号接收机处在交织模式)，则程序进到方块68，此时程序结束。 If it is determined at block 56 the television signal receiver 22 is not in progressive mode (with "NO" for No, a television signal receiver is in interleaving mode), the program proceeds to block 68, then the program ends. 如果在方块56确定电视信号接收机22是处在逐行模式(用“是”代表是)，则程序进到方块58。 If it is determined at block 56 the television signal receiver 22 is in the progressive mode ("yes" for YES), the program proceeds to block 58.
在方块58，程序确定主视频信号的当前的行号是否用于场1的。 At block 58, the program determines the main video signal of the current line number is 1 for the field. 如果确定当前的行号不是用于场1的(用“否”代表否)，则程序进到方块68并结束。 If determined that the current line number is not used in field 1 (with "NO" no), the program proceeds to block 68 and ends. 如果确定当前的行号是用于场1的(用“是”代表是)，则程序进到方块60。 If determined that the current line number is for a field 1 ("yes" for YES), the program proceeds to block 60. 方块60和它的随后的步骤是在以上讨论的。 Block 60 and its subsequent steps are discussed above.
从图5的流程图50可以看到，电视信号接收机22如何以一个示例性方式检测辅助视频信号是否处在与主视频信号相同的场以提供闭路字幕。 50 from the flowchart of FIG. 5 can be seen, the television signal receiver 22 an exemplary manner how to detect whether the auxiliary video signal in the same field of the main video signal to provide a closed caption. 在这个程序中，行号中断(诸如行号4-5)可被提供为垂直中断，以便即使在主显示信号(主视频信号)生成装置处在逐行模式而不是交织模式时，仍旧有可能通过这个垂直中断得到场1中断。 In this program, the interrupt line number (such as a line number 4-5) may be provided as a vertical interrupted, so that even when the main display signal (main video signal) generating means is in the progressive mode instead of interleaved mode, it is still possible Through this vertical field interruption get a break. 因此，这就是为什么程序需要检验当前的行号的原因。 So this is the reason why the program needs to examine the current line number. 为了检测主和辅助是否在同一个场，也可能希望控制延时(例如，加上某些滞后)，用于阻止1-2临时场倒置。 In order to detect the primary and secondary are in the same field, it may be desirable to control the delay (for example, with some lag), 1-2 to prevent temporary field inversion.
现在参照图6，图上显示用于把闭路字幕数据插入到辅助缓存器40用于下一个场，以便使提取的闭路字幕数据与辅助视频信号的程序同步的流程图，总的表示为70。 Referring now to Figure 6, the figure shows means for inserting closed caption data to the secondary cache 40 for a next field, so that the extracted closed caption data with the auxiliary video signal to synchronize the program flow chart, indicated generally as 70. 在方块72，用于往外提供闭路字幕数据的程序开始。 At block 72, to provide for closed caption data out of the program starts. 此后，在方块74，电视信号接收机确定是否正在使用去交织，以及如果是的话，这些场是否为奇数。 Thereafter, at block 74, the television signal receiver is being used to determine whether the de-interleaving, and if so, whether such field is odd. 如果确定没有使用去交织(用“否”代表否)，则程序进到方块78。 If it is determined not to use interleaving (with "NO" no), the program proceeds to block 78. 如果确定正在使用去交织(用“是”代表是)，则程序进到方块76。 If it is determined being used to interleave ("yes" for YES), the program proceeds to block 76. 在方块76，输出的场被倒置。 In block 76, the field output is inverted. 此后，程序进到方块78。 Thereafter, the program proceeds to block 78.
在方块78，程序确定主显示是否处在逐行模式。 In block 78, the program determines whether the main display in progressive mode. 如果主显示被确定为处在逐行模式(用“是”代表是)，则程序进到方块80以及输出场被倒置。 If the main display is determined to be in progressive mode ("yes" for YES), the program proceeds to block 80 and the output field is inverted. 程序然后进到方块82。 The program then proceeds to block 82. 在方块78，如果主显示被确定为不处在逐行模式(用“否”代表否)，则程序进到方块82。 At block 78, if the main display is determined to be not in progressive mode (with "NO" no), the program proceeds to block 82.
在方块82，电视信号接收机确定场倒置模式是否“接通”(如由图5的程序50设定)。 At block 82, the television signal receiver determines whether the mode field of an inverted "on" (as indicated by the setting program 50 in FIG. 5). 如果场倒置模式是“接通”(用“是”代表是)，则程序进到方块84。 If field inversion mode is "ON" ("yes" for YES), the program proceeds to block 84. 在方块84，电视信号接收机把输出场倒置。 At block 84, the television signal receiver output field inversion. 此后，程序进到方块86。 Thereafter, the program proceeds to block 86. 如果电视信号接收机在方块82确定场倒置模式没有“接通”(用“否”代表否)，则程序进到方块86。 If the television signal receiver determines the field inversion mode in block 82 is not "on" (with "NO" no), the program proceeds to block 86. 在方块86，程序然后把闭路字幕数据放置到辅助输出端。 In block 86, the program then placing the closed caption data to the secondary output. 此后，程序在方块88结束。 Thereafter, the routine ends at block 88.
从图6的流程图70可以看到，电视信号接收机22如何以一个示例性方式把闭路字幕数据放置在当前的场。 70 from the flowchart of FIG. 6 it can be seen how the television signal receiver 22 an exemplary manner to closed caption data is placed in the current field. 对于包括去交织器的系统，必须把场信息倒置一次，因为系统将引起一个场的延时，如果去交织器正在工作的话。 For a system comprising a deinterleaver, field information must be inverted once, because the system will cause a delay of one field, if the deinterleaver working words. 对于在主视频信号上的逐行模式，必须倒置场信息一次，因为这种情形将有一个场的延时。 For a video signal on the main progressive mode, you must invert the field of information once, because this situation would have delayed a farm. 另外，有可能使用来自图5的程序50的场倒置信息、所以，如果这里识别的情形被检验为如上所述，则这里描述的系统使得把闭路字幕数据放置在正确的场成为可能。 Further, it is possible to use the program from the field 50 of Figure 5 inverted information, therefore, if the case where the identification is verified as described above, the system described herein enables the closed caption data is placed in the correct field becomes possible.
