Embodiment

[0037] The information display platform (also called SPIDer platform) of the present invention includes a main node machine and several sub-node machines, the main node machine and multiple sub-node machines are connected to each other through a computer network, and multiple display units are respectively configured for each sub-node machine. The information display platform is a comprehensive system platform integrating multi-screen image processing technology, signal conversion technology, network technology, and information processing, analysis, management and display of massive information processing technology. Based on cloud computing, it supports massive information processing and display. Good flexibility, expansibility, and high cost-effectiveness have fully utilized the processing capabilities of computers. By building parallel display functions on node machines, a highly coordinated distributed display cluster rendering system has been established to achieve high-per...

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...
