Abstract

The invention discloses a video code rate real-time adjusting device and system, and a video server. The video code rate real-time adjusting device based on a wireless network comprises a processor for realizing each instruction; and a storage for storing multiple instructions, wherein the instructions are suitable for loading and executing by the processor; the multiple instructions comprise the following steps: obtaining a packet loss rate according to packet loss information detected by a video receiving end; predicting the video code rate of the network according to the packet loss rate to obtain the predicted code rate; judging whether the current network is in congestion according to the video data confirmation information fed back by the video receiving end; if the current network is in congestion, adjusting the real-time code rate according to the predicted code rate, and sending the video data according to the adjusted code rate. Whether the current wireless network is in congestion is judged according to the packet loss rate and like information at the video receiving end; if the current wireless network is in congestion, the sending code rate of the video data is immediately adjusted to reduce the congestion state of the wireless network, thereby improving the transmission efficiency of the video data.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a device and system for real-time adjustment of a video code rate, and a video server. Background technique [0002] With the development of Internet technology, the wireless network has developed rapidly, which is convenient for people to work and live, and at the same time puts forward higher requirements for the performance of the wireless network, such as the real-time performance of the wireless network. Especially in the field of public security, there are all-weather and all-terrain requirements for real-time video transmission, and providing high-definition video transmission with low delay is conducive to timely grasping of on-site conditions. However, due to the flaws of wireless networks, it is easy to cause packet phenomenon in network transmission. Generally speaking, the reasons for packet loss can be roughly divided into two categories: one is caused by network c...
