The present application relates to a large-screen mosaic synchronization method and system, and relates to the technical field of computer multimedia. The method includes: modifying the structure of at least two decoder boards, correspondingly installed in at least two screens; setting one decoder as the master node, and obtaining the crystal oscillator time of all decoders through the master node; setting the time labels of all crystal oscillators, Make the time stamp of each crystal oscillator correspond to one frame of picture; check the time stamp of all crystal oscillators through the master node, and each decoder caches at least one frame of picture; take the master node as the initial time coordinate, and send the crystal oscillator time of the master node to other decoders Crystal oscillator: According to the initial time coordinates, the screen corresponding to the time label of each crystal oscillator is played synchronously. The large-screen mosaic synchronization method and system of the present application modify the structure of the decoder board, dock and install it inside various large screens, and connect to the network through a network cable to realize large-screen splicing, complete the synchronization function, and improve user experience.
Description
technical field [0001] The present application relates to the field of computer multimedia technology, in particular to a large-screen splicing synchronization method and system. Background technique [0002] With the advent of the information age, the rapid development of computer multimedia technology and the wide application of network technology, from the establishment of command and monitoring centers and network management centers to the conduct of conferences and technical lectures, it is necessary to obtain large-screen, multi-color, high-brightness, High-resolution display effect, while the traditional display is difficult to meet the various requirements of users. In the context of intelligent information construction, cloud technology is a general term for network technology, information technology, integration technology, management platform technology, application technology, etc. based on cloud computing model applications. Cloud computing (Cloud Computing) is...
