The present application relates to a 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, which are correspondingly installed inside at least two screens; setting one decoder as the master node to synchronize the clocks of all decoders; correcting the crystal oscillator time of the hardware board so that each One frame of video picture corresponds to the time point of the crystal oscillator; each device caches at least one frame of video picture after decoding; when the decoder clock is synchronized, it corresponds to the time of the crystal oscillator, and the cached video picture is played through the time point of the crystal oscillator. The screen splicing synchronization method and system of the present application integrates distributed boards and large screens, and connects switches through network cables to exchange audio and video data. No redundant equipment is required to realize the splicing function. After splicing large screens, the images are synchronized and consistent. No tearing phenomenon, comprehensively improve user experience.
Description
technical field [0001] The present application relates to the field of computer multimedia technology, in particular to a method and system for synchronizing screen splicing. 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 a k...
