Abstract

The invention discloses a method, device, system and readable storage medium for distributed super-large resolution audio and video display and control. The signal stream type to which the first audio and video signal stream belongs; if the first audio and video signal stream is a combined signal stream, all the first audio and video signal streams are synchronously processed, and the first audio and video signal stream after the synchronous processing is processed Encoding is performed to obtain the first audio and video signal frame; the same first time stamp is added to the first audio and video signal frame to obtain the second audio and video signal frame; the second audio and video signal frame is forwarded to the decoding node through the switch, and the decoding node Synchronously decode the second audio and video signal frame based on the first time stamp to obtain the second audio and video signal stream; send the second audio and video signal stream to the LED screen to display the audio and video corresponding to the second audio and video signal stream, solving the problem of Fixed the problem of out-of-sync playback on the splicing screen.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an audio and video display control method, device, system and computer-readable storage medium. Background technique [0002] With the continuous development of display technology, ultra-large resolution display solutions based on 4K resolution display units are becoming more and more popular. Multi-graphics splicing output multimedia material itself is of super-large resolution, which needs to be displayed on the splicing screen. This technology of outputting super-large-resolution multimedia material through the splicing screen is widely used in various big data command centers, monitoring, operation and maintenance scheduling Centers, large conference rooms, exhibition halls and other scenes. [0003] The node units of the traditional distributed splicing screen system are powered separately and transmit data through the network port. This form of networking is easie...
