Abstract

The invention discloses a video transmission system based on an H.264 network, which belongs to the field of video transmission and comprises a server side and a client side which are connected. The server side comprises a packaging module reading and separating module, a protocol setting module, a protocol data packet packaging module and a protocol sending module. The client comprises a protocolreceiving module, a protocol parsing module, a module combining module and a playing module. According to the invention, the NALU data and the RTP data are packaged and packed at the server side; when the client side is conducted, unpacking and unpacking can be quickly carried out, so that the video transmission speed is higher, and the efficiency is higher, high-definition video transmission isbetter met; and meanwhile, through testing, the client side can smoothly play after being buffered for 2 seconds, the phenomena of packet loss, smear and the like do not occur under the condition thatthe transmission speed is set to be 30 frames per second, and the subjective quality of the video is good.

Description

technical field [0001] The invention relates to the field of video transmission, in particular to an H.264-based network video transmission system. Background technique [0002] Network video surveillance is currently in a stage of vigorous development, and there are some problems in the development process: insufficient network bandwidth, insufficient video clarity, and huge storage capacity. These problems are all problems to be solved in the development of network video surveillance, but after analysis, it can be found that it is only a problem of video coding and compression, a superior video compression standard. The compression ratio of the video compressed by superior video compression standards will increase, and the video capacity will decrease. Naturally, the demand for network bandwidth will decrease, and the required storage capacity will also decrease accordingly; the video compressed by superior video compression standards will clearer. From another perspecti...
