Problems solved by technology

However, the built-in decoding judgment module cannot accurately judge the correctness of the video signal and cannot avoid displaying abnormal images
That is, if there is an EDID version incompatibility problem, users will still see abnormal images for a period of time, which still cannot solve the problem of user experience

Abstract

The embodiment of the invention provides an EDID self-adapting method and system, belonging to the field of display. The EDID self-adapting method comprises the following steps: a display device sets a SCDC support flag bit; when an external device reads the SCDC support flag bit, the SCDC support flag bit is used for determining whether the display device supports SCDC or not; if the display device supports SCDC, the external device sets an HDMI version flag bit, otherwise, the external device does not set the HDMI version flag bit; and the display device reads the HDMI version flag bit and sets the corresponding EDID file according to the HDMI version flag bit, so that the display device processes and displays the source data transmitted by the external device. By means of the EDID self-adapting method and system, the accuracy of automatic switching of the EDID versions can be increased, therefore, the comfort of the user experience can be improved.

Description

technical field [0001] The present invention relates to the display field, in particular to an EDID adaptive method and system. Background technique [0002] For each HDMI (High Definition Multimedia Interface, high-definition multimedia interface) receiver, there will be an EDID (Extended Display Identification Data, extended display identification data) file to indicate the specific support of the HDMI receiver for audio and video. In order to support the transmission and display of 4K@50Hz / 60Hz signals, the HDMI standard has been upgraded from version 1.4 to version 2.0, and the corresponding EDID version has also been upgraded simultaneously. However, the EDID version suitable for HDMI 2.0 and the EDID version suitable for HDMI 1.4 are not compatible with each other in standard design, resulting in incorrect identification of display devices that only support HDMI 1.4 (such as DVD players and network set-top boxes, etc.) The EDID version corresponding to HDMI2.0 often c...
