The invention discloses a distributed super-large resolution audio and video display control method, device and system and a readable storage medium. The method comprises the steps: controlling a coding node to collect a first audio and video signal stream from a display card head corresponding to the coding node, and judging the type of the signal stream to which the first audio and video signalstream belongs; if the first audio and video signal streams are combined signal streams, synchronizing all the first audio and video signal streams, and encoding the synchronized first audio and videosignal streams to obtain a first audio and video signal frame; adding the same first timestamp to the first audio and video signal frame to obtain a second audio and video signal frame; forwarding the second audio and video signal frame to a decoding node through a switch, and synchronously decoding the second audio and video signal frame by the decoding node based on the first timestamp to obtain a second audio and video signal stream; and sending 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, thereby solving the problem of asynchronous playing of the spliced 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...
