Title: INFORMATION TRANSMISSION METHOD, VIDEO PLAYING DEVICE AND VIDEO DISPLAY DEVICE
Abstract:
The present invention relates to an information transmission method, a video playing device and a video display device. The information transmission method comprises: sending an information read instruction to a video display device; acquiring EDID according to a preset acquisition rule, and extracting display parameters in the EDID; determining whether the display parameters successfully match playing parameters of a video playing device; transmitting video data matching the EDID to the video display device if the display parameters successfully match the playing parameters; and reacquiring the EDID according to the preset acquisition rule if the display parameters unsuccessfully match the playing parameters, wherein the version of the EDID acquired by the video playing device each time is different. The technical solution provided by the present invention enables the video playing device to read EDID matching playing capabilities of the video playing device, so that video data can be successfully transmitted to the video display device.
