The invention relates to a large 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 a decoder as a main node, and obtaining the crystal oscillationtime of all decoders through the main node; setting time labels of all the crystal oscillators, and enabling the time label of each crystal oscillator to correspond to one frame of picture; calibrating the time labels of all the crystal oscillators through the main node, wherein each decoder caches at least one frame of picture; sending the crystal oscillator time of the main node to other decoder crystal oscillators by taking the main node as an initial time coordinate; and synchronously playing the pictures corresponding to the time labels of the crystal oscillators according to the initialtime coordinate. According to the large screen splicing synchronization method and system, the decoder board card structure is modified, the decoder board card structure is installed in various largescreens in a butt joint mode, large screen splicing is achieved by accessing the network through the network cable, the synchronization function is completed, and the user experience is improved.
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...
