Problems solved by technology

Some traditional video tours need to frequently close and open video sources, and the picture switching is not smooth; some need to open all video sources and display different pictures at a specified time, so that the picture switching is smooth, but the number of tours is limited by CPU, bandwidth, etc. Server system resource limitations

Embodiment Construction

[0009] In order to allow those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described below in conjunction with the accompanying drawings.

[0010] The present invention discloses a video surveillance-based multi-screen tour method, including: (1) the IP source data reading thread stores the program source data into the ring data buffer; (2) one or more program decoding threads read from The ring data buffer screens out the data packets corresponding to the audio and video PID of the program, decodes them, and outputs them to the display window; (3) Perform program switching according to the preset time.

[0011] Before starting to play, configure the program source, use the code stream analysis process to analyze all the program audio and video information and IP source information in the program source, and store them in the database. Such as figure 1 As shown, after the process of playing th...

Abstract

The invention discloses a multi-screen alternate touring method based on video monitoring. The method includes the steps that an IP source data reading thread stores program source data into an annular data buffer area; one or more program decoding threads screen out program audio and video PID data packages corresponding to the program decoding threads from the annular data buffer area and then decode and output the program audio and video PID data packages to a display window; programs are switches over according to preset time. According to the method, the programs are broadcast by starting up one IP source data reading thread and multiple program decoding threads, quick alternate touring of the programs is achieved, cost is low, and the amount of the alternate touring can not be influenced by server performance.

Description

technical field [0001] The invention relates to a video surveillance-based multi-picture round-robin method. Background technique [0002] At present, the number of programs that can be monitored in real time by one server of a general multi-screen monitoring system is limited. Taking MPEG-2 standard definition as an example, the maximum supported number is about 100. Nowadays, the actual number of monitors that many TV stations need to monitor can easily exceed this amount, so multiple servers have to be purchased. In order to save costs, the multi-screen tour function came into being. Some traditional video tours need to frequently close and open video sources, and the screen switching is not smooth; some need to open all video sources and display different pictures at a specified time, so that the screen switching is smooth, but the number of tours is limited by CPU, bandwidth, etc. Server system resource limitations. Contents of the invention [0003] In order to so...
