Intelligent dynamic high-definition video transmission system

Abstract

Disclosed in the invention is an intelligent dynamic high-definition video transmission system comprising a pick-up head, an embedded video processing board, and a portable terminal. The embedded video processing board obtains video data from the pick-up head; after processing of video A / D chip digitization, the processed data are sent to a DM 365 processor; the processor completes H.264 real-time compression and coding on the video by using an H.264 high-definition video image coprocessor (HDVICP) in an internal integration mode and an H.264 video stream is outputted; an ARM terminal program receives the H.264 video stream and carries out packaging on the video stream based on a proper packaging strategy to generate an RTP pack; when an RT-SP server side program receives a client request, the packaged RTP pack is sent to a receiving terminal; and portable terminals of a plurality of different platforms receive and decode the code stream and then display the video, thereby realizing real-time video transmission. According to the invention, with the TMS320DM365 digital media processor and the Montavista Linux embedded system, real-time video collection, H.264 coding, H.264 video stream packaging and transmission can be realized.

Description

technical field [0001] The invention relates to a video transmission system, in particular to an intelligent dynamic high-definition video transmission system. Background technique [0002] With the increasing maturity of video coding and decoding technology and the continuous development of network communication technology, video transmission system has been widely used in the fields of intelligent transportation, intelligent buildings, hospital campuses, shopping malls and supermarkets, enterprise production and living quarters. The front end of the system is developing in the direction of integration, digitalization, networking, and integration. Among them, the embedded system is valued because of its small size, low power consumption, and powerful functions. Especially with the continuous improvement of wireless network bandwidth, smart phones have become mobile display terminals, integrated into people's lives, and playing an increasingly important role.

Problems solved by technology

The H.264 standard has high-efficiency video compression performance and good network adaptability, and is very suitable for the transmission of video streams under the condition of limited bandwidth, but its excessive calculation limits the application on the embedded platform with limited resources, because Encoding takes too long to meet the needs of real-time video transmission
