Screen splicing synchronization method and system

Abstract

The invention relates to a screen splicing synchronization method and system, and relates to the technical field of computer multimedia. The method comprises the following steps: modifying at least two decoder board card structures, and correspondingly installing the decoder board card structures in at least two screens; setting one decoder as a main node, and performing clock synchronization of all decoders; correcting the crystal oscillator time of a hardware board card to enable each frame of video picture to correspond to the time point of the crystal oscillator; by each equipment, cachingat least one frame of video picture after decoding; and when the decoder clock is synchronized and corresponds to the crystal oscillator time, playing the cached video picture through the time pointof the crystal oscillator. According to the screen splicing synchronization method and system, the distributed board card and the large screen are integrated, the switch is connected through a networkcable, audio and video data exchange is carried out, the splicing function is achieved without redundant equipment, the images are synchronous and consistent after the large screen is spliced, the tearing phenomenon is avoided, and the user experience is comprehensively improved.

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...

Problems solved by technology

Among them, the video processor (fighting control) has centralized management problems, which leads to high system risks, and problems such as high cost of expansion and complex construction.

Distributed splicing has problems such as poor synchronization and cumbersome construction. For example, after splicing large screens, different pictures or even tearing will appear.
