The LVDS receiver 12 can also request the LVDS sender 100 to identify different types of pixels in the unused bits of the LVDS transmission protocol, in other words, using the information represented by the controller (eg, reserved bits). The definition of the communication information can be communicated between the LVDS transmitting end 1 and the LVDS receiving end 120 through the communication interface. However, the present invention is not limited thereto. For example, if the LVDS transmitting end i 〇〇 and the lvds receiving end 120 have a protocol, the communication interface may not be used. The LVDS transmission end point and LVDs and the receiving end 12G are respectively implemented as system boards and display devices in the television system, and the OSD is used as a specific display content for illustration. As shown in FIG. 3, the data processor 302 in the system board 300 receives the externally input image data and the (10) data and the 〇SD control provided by the internal OSD generator 3〇4 to process the display data and (10)d control information. And transmitting the display data and the 0SD control information to the lvds transmitter; the OSD control information can be embedded in the pixel data of the 201228385 corresponding to the sd data by the data processor 3〇2, and the image of the OSD is achieved.

It can be known here that the fixed motion 1 and the OSD control information enable the transmission interface to be internal. The 0SD data display device 320 allows the LVDS receiver to transmit the information to the data processing via the =vd G==〇SD control message, and then the i-line is processed. =疋 used to present the pixel data of 〇SD, and, in particular, for the pixel poem 4 that is not used to render 〇SD, it will do the same kind of exercise/object, and the current pixel will be special. The protection is not subject to it; the signal is pixel level and its accuracy is accurate with the transmission of the pixel data. Finally, the image data output by the m 322 is finally displayed on the screen 1 of the display device 320. The SD is displayed on the top of the screen on the top of the display device, and replaces a part of the image in the corresponding position in the image data that is displayed at the same time. It is worth mentioning that the embodiment of the present invention shows the use of the stereo image. Advantages 'Because stereo images are easy to change due to time changes. 'OSD's will become very complicated. The current motion estimation/sports technology can't effectively protect the SD in stereo images; Example: 0SD control With the pixel data is transmitted together, the heart '
