Abstract

The invention provides a 3G video transmission method and system based on compression sensing in a video monitoring scene, and belongs to the field of data compression and video transmission. After the format of video information collected by a camera is converted into the YUV format through color space conversion, H.264 coding is conducted, compression processing of compression sensing is conducted on coded data, video data streams obtained through compression are transmitted in a 3G network according to the RTSP protocol and the RTP / RTCP protocol, and reconstruction processing of compression sensing and the H.264 decoding process are conducted at a terminal so that restored video information can be obtained. Compression sensing is combined with the RTSP protocol and the RTP / RTCP protocol to be used in the 3G video transmission system, and therefore the system can meet the requirement for instantaneity of video transmission from the aspects of control and data, the system has the self-adaption video coding speed and network transmission speed regulation function, the size of the data transmitted through a network can be greatly reduced, broadband resources are saved, and the transmission efficiency of the system is improved.

Description

technical field [0001] The invention relates to a video transmission system, which belongs to the field of data compression and video transmission, in particular to a 3G video transmission method and system based on compressed sensing in video monitoring. Background technique [0002] With the continuous development of communication technology, 3G wireless network CDMA2000-1X EVDO network has been fully put into commercial use. As the most mature wireless network, it has key technologies such as advanced front-end forward link and resource scheduling. , video transmission, monitoring systems and other aspects have a far-reaching impact. At the same time, the transmission of video services in the communication network is becoming more and more important, and as we all know, the video itself is characterized by a huge amount of data, which requires a large bandwidth during transmission. Due to the considerable redundancy of the video itself, various compression methods have b...
