Real-time video stream display method and system based on information display platform

Abstract

The invention relates to a real-time video stream display method and a system based on an information display platform. The method mainly comprises the steps: after video stream data are received, a video stream data format is analyzed, and the effective video stream data are buffered; the effective video stream data are unpacked, and original video stream data are obtained and decoded; display of the video stream data is controlled; a format of the video stream data after decoding is judged and is converted a format which can be displayed on the information display platform; a host node machine monitors and preprocesses a control operation order of a video stream, each sub node machine completes display operation in the order after preprocessing in parallel, and the host node machine sends a synchronous display order to all the sub node machines; and video stream display data are respectively sent to a display card buffering zone in each sub node machine and synchronously displayed in a plurality of display units. The real-time video stream display method and the system based on the information display platform achieve the functions of screen-striding synchronization, movement, contraction and amplification, lamination and the like of video stream display.

Description

technical field [0001] The invention relates to technical fields such as video processing, ultra-high resolution display, multi-screen image processing, and massive information display synchronization, and in particular to a real-time video stream display method and system based on an information display platform. Background technique [0002] With the popularization of the Internet and the rapid development of video codec technology, real-time video streaming related applications are becoming more and more extensive, such as video conferencing, distance education, remote monitoring, security monitoring, etc. In recent years, with the emergence of high-definition video, the entire video industry is ushering in the era of marching towards high-definition, and real-time video is also moving from analog to digital and networked, becoming video streaming. Especially with the arrival of the climax of building a safe city in China, high-definition video stream display has become t...
