Method, device and system for recording and replaying full-screen ultrahigh-resolution picture of display wall

Abstract

The invention relates to the technical field of audio and video processing, and discloses a full-screen ultrahigh-resolution picture recording and playback method, device and system for a display wall. The recording and playback server stores the obtained picture recording data of the target display wall to the local, when the playback instruction is received, the player is created on the desktop, and the player decodes multiple video code streams and one audio code stream in the picture recording data, so that the video code streams and the audio code streams in the target display wall are decoded, and the playback of the target display wall is realized. The video frames obtained through decoding are spliced into a complete picture according to the respective recording area positions to be played, the resolution of the complete picture is the same as the picture resolution of the target display wall, meanwhile, audios obtained through decoding are synchronously played, and playing data are output to a processor of the display wall to be played back. And the playback of the picture recording data is realized. According to the invention, the video playback requirements of ultra-high-definition playback, audio and video synchronization and picture synchronization can be met at the same time, and the applicability is wide.

Description

technical field [0001] The invention relates to the technical field of audio and video processing, in particular to a method, device and system for recording and playing back full-screen ultra-high-resolution images of a display wall. Background technique [0002] In the meeting scene of monitoring room and meeting room, it is sometimes necessary to record the entire playback screen of the large display wall as a video and record it to the storage disk, and then record the recorded video on the large display wall when viewing the meeting records later Play, that is, video playback. When performing video playback, the following requirements must be met: (1) ultra-high-definition playback, preferably the resolution of the recorded video is consistent with the resolution of the entire large screen of the display wall; (2) audio and video synchronization, that is, audio and video during video playback Keep synchronous; (3) The playback screen is synchronous, because the large s...
