The invention discloses a transmission method of multichannel video streams and a system thereof. The system comprises a client and a server. The client comprises a video receiving module, a video processing module and a client session module. The server comprises: a plurality of video sending modules, which are matched with the video receiving module, and a server session module. The client session module is used to complete signaling interaction with the server session module and control the video receiving module to receive video data packets transmitted by the server. The video processingmodule is used to process the video data packets received by the video receiving module. The server session module controls the video sending modules to send the video data packets to the client. In the invention, video source validity verification and video data packet validity verification are added during a video request negotiation process by the client so that correctness and reliability of the video stream transmission can be raised.
Description
technical field [0001] The invention belongs to the technical field of mobile communication networks, and more specifically relates to a transmission method and system for multi-channel video streams. Background technique [0002] At present, with the continuous development of wireless technology and the continuous improvement of wireless bandwidth, human society has gradually entered the era of 3G and LTE high-speed wireless networks. [0003] In a high-speed wireless network environment, the original network video surveillance front-end can already transmit video streams through the wireless network. Generally, ordinary wireless front-end equipment generally provides single-channel data transmission services, and in an environment with a certain video stream, single-channel data transmission services can already meet the demand. However, as users have higher and higher requirements for video, the user's requirements for the resolution of video streams have also developed ...
