The invention discloses a conference television video output EDID (Extended Display Identification Data) processing method and system, belonging to the field of multimedia video. The method comprises the steps: a drive module of a conference television terminal queries EDID data of a monitor and sends the EDID data to a service assembly module of the conference television terminal; the service assembly module generates a configuration system command according to the EDID data and sends the configuration system command to a system conversion device; and the system conversion device generates a video signal adapting to the configuration system mode according to the configuration system command and outputs the video signal to the monitor. The conference television terminal disclosed by the invention outputs the corresponding video signal according to the queried EDID data of the monitor, solves the problem of unsuitability of video systems and resolutions supported by the video output mode and system of the conference television terminal and the monitor connected with an output interface, and has the beneficial effects of being capable of automatically selecting an output mode and system and being also capable of furthest developing display characteristics of the monitor.
Description
technical field [0001] The present invention relates to the field of multimedia video, in particular to a video conference video output EDID (Extended Display Identification Data, extended display identification data) processing method and system. Background technique [0002] EDID is a VESA (Video Electronics Standards Association, Video Electronics Standards Association) standard data format, which contains parameters about videoconferencing monitors and their performance, including supplier information, maximum image size, color settings, manufacturer presets, Frequency range limits and strings for display name and serial number. [0003] The conference TV terminal supports a variety of video output interfaces, including VGA (Video Graphics Array, video graphics array), Ypbpr (progressive scan color difference output), SDI (serial digital interface, digital serial interface), HDMI (High Definition Multimedia Interface, High-definition multimedia interface), etc., and the...
