Streaming media transmission self-adaptive system in wireless network system

Abstract

The invention discloses a streaming media transmission self-adaptive system in a wireless network system, belonging to the technical field of video monitoring, which consists of a video coding module, a streaming media sending module and a controlling module, wherein the video coding module is connected with the streaming media sending module; the streaming media sending module is connected with the controlling module; and the controlling module is connected with the video coding module. According to the self-adaptive system, the network service quality is controlled by a front-end module; according to the dynamic of the current network status, a coder is regulated, so that a generated code flow is suitable for the transmission of the current network; based on a transmission control protocol (TCP) transmission, the self-adaptive system has the advantages of good video effect of the client side, no vibration, few mosaic, short time, no packet loss and stable and reliable operation, and is capable of saving a great amount of network flow expenses caused by the packet loss.

Description

Technical field: [0001] The invention relates to the technical field of video monitoring, in particular to an adaptive system for streaming media transmission in a wireless network system. Background technique: [0002] In the field of video surveillance technology, from front-end video collection and compression to back-end client browsing, the transmission of video streaming media often uses UDP protocol transmission. In traditional UDP transmission, the quality of service is controlled by the client, and the client will drop the network packet The situation is sent to the front-end module, and then the front-end module makes adjustments according to the feedback from the client. This kind of feedback is relatively slow and not timely, which causes the video effect of the client to not be improved in time, especially the wireless network. Compared with the wired network, the bandwidth is small and the network Poor quality and serious packet loss will cause large jitter, ma...

[0002] In the field of video surveillance technology, from front-end video collection and compression to back-end client browsing, the transmission of video streaming media often uses UDP protocol transmission. In traditional UDP transmission, the quality of service is controlled by the client, and the client will drop the network packet The situation is sent to the front-end module, and then the front-end module makes adjustments according to the feedback from the client. This kind of feedback is relatively slow and not timely, which causes the video effect of the client to not be improved in time, especially the wireless network. Compared with the wired network, the bandwidth is small and the network Poor quality and serious packet loss will cause large jitter, many mosaics, long time and poor effect when watching real-time video at the back end, which cannot achieve the purpose of monitoring, and the wireless network traffic is large and the cost is high
