Abstract

The invention discloses a self-adaptive method, device and system for multimedia information acquisition. The method comprises the steps of acquiring extended display identification data EDID of a display device connected with a receiving end, sent by the receiving end; detecting the EDID according to a preset condition, and modifying the EDID according to a detection result; and setting the modified EDID in acquisition equipment, so that sending end equipment performs display resolution and audio format negotiation with the receiving end by reading the EDID and the receiving end of the acquisition equipment. The technical problem that the receiving end cannot play audios and videos normally due to the technical defects of audio and video information processing in an audio and video transmission process in the prior art is solved.

Description

technical field [0001] The invention relates to the application field of image transmission technology, in particular to an adaptive method, device and system for collecting multimedia information. Background technique [0002] In the process of audio and video playback, especially after the remote transmission of audio and video, the receiving end plays the audio and video files sent by the sending end. Since it is necessary to ensure that the playback effect of the receiving end is consistent with the effect displayed by the sending end, the receiving end must The process of audio and video files mainly includes the following two processing methods: [0003] Method 1: Realize resolution negotiation by pure software. The software needs to perform scaling control according to the negotiation protocol, and finally achieve the matching effect with the display device at the receiving end by using scaling means. The disadvantage of this method is that it relies too much on sca...
