EDID (Extended Display Identification DATA) A data specification for a video display device (such as a display) that contains display parameters that reflect the display capabilities of a video display device. The display parameters include parameter information such as the version number of the EDID itself, the resolution of the video display device, the display timing, and the display size. Since the EDID includes the above display parameters of the video display device, when the video playback device (such as a DVD player) establishes a connection with the video display device, the video playback device can determine whether the playback capability of the video playback device is compatible with the video by acquiring the EDID. The display capabilities of the display device are matched, and the video data adapted to the above display parameters is further transmitted to the video display device. Among them, the video playback device for the acquisition of EDID and the transmission of video data is usually implemented by HDMI (High Definition Multimedia Interface). 1 is a schematic diagram of interaction between a video playback device and a video display device in the prior art. As shown in FIG. 1 , a video playback device and a video display device are generally provided with HDMI, an HDMI of the video playback device itself, and an HDMI of the video display device. The connection between the EDID and the video data is realized by establishing a connection relationship through the data transmission channel, and the data transmission channel includes three TMDS (Transition Minimized Differential Signaling) channels and control/status signals for transmitting video data. 1 TMDS clock channel, and DDC (Display Data Channel) for transmitting EDID. The specific information transmission process is as follows: When the video playback device establishes a connection with the video display device, the video playback device reads EEPROM (Electrically Erasable Programmable Read-Only Memory) through the HDMI in the video display device. Stored EDID; when the video playback device determines its own playback capability and the display in the read EDID When the parameters are adapted, the video playback device passes the video data to the video display device via the TMDS channel between the HDMIs to cause the video display device to display the video data. However, the display capabilities of the video display device reflected by the display parameters in different versions of the EDID are not consistent, and the display capability does not necessarily match the playback capability of the video playback device itself, so that the video data in the video playback device does not necessarily adapt to the EDID. The parameters are displayed such that the video playback device may not transmit video data to the video display device, further causing the video display device to be unable to display data, thereby affecting the user experience. SUMMARY OF THE INVENTION The present invention provides an information transmission method, in order to overcome the problem that the video data in the video playback device does not necessarily adapt to the display parameters of the EDID, and the video playback device may not transmit the video data to the video display device. Video playback devices and video display devices. According to a first aspect of the present invention, there is provided an information transmission method for a video playback device, the information transmission method comprising: transmitting an information read instruction to a video display device, the information read instruction for reading the video Displaying the extended display identification data EDID of the display device; acquiring the EDID according to the preset acquisition rule, and extracting display parameters in the EDID; determining whether the display parameter matches the play parameter of the video playback device itself; If the display parameter is successfully matched with the play parameter, the video data that matches the EDID is transmitted to the video display device; if the display parameter fails to match the play parameter, the preset acquisition rule is re- Obtaining the EDID, wherein the version of the EDID acquired by the video playback device is different each time. The information read command is sent to the video display device by the video playback device to obtain the EDID according to the preset acquisition rule. When the display parameter in the EDID fails to match the play parameter of the video playback device, the EDID is reacquired according to the preset acquisition rule. , each time the version of the EDID obtained is different. Therefore, the video playback device can match the playback parameters of the video display device with the EDID of the different versions of the video display device, and reduce the situation that the display parameters reflected by the single EDID do not match the playback parameters, and the video data cannot be transmitted.

The version of the EDID sent each time is different. Therefore, when the matching fails, the video playing device can match the playing parameters of the video display device with the EDIDs of the different versions of the video display device, respectively, and reduce the display parameters reflected by the single EDID and the play parameters do not match. In the case of transmitting video data, the possibility that the video playing device transmits video data to the video display device is increased, and the video display device can successfully display the video data, thereby improving the user experience. Optionally, the sending the EDID to the video playing device according to the preset sending rule includes: sequentially sending the EDID according to a version priority of all EDIDs in the video display device, where Send the EDID with the highest priority in the version. By sequentially sending an EDID to the video playback device according to the priority of the version of all EDIDs in the video display device, the display parameters reflected by the EDID with the highest version priority can be preferentially matched with the playback parameters, thereby increasing the probability of matching and improving the matching.
