The adaptive transmission bit rate.
Adaptive streaming bitrate is a technique used in streaming multimedia over computer networks.
While much of video is in the past, current technologies are used by current protocols such as RTP with RTSP, today’s adaptive technologies are almost exclusively based on HTTP and designed to work efficiently over large, distributed HTTP networks. like the internet.
It works by detecting user bandwidth and CPU capacity in real time and adjusting the quality of the video stream accordingly. This requires the use of an encoder that can encode single source video at multiple bit rates. The player client switches between streaming different encodings based on available resources. “The result: very little buffering, fast startup times, and a good experience for both high- and low-level communications.”
More specifically, and as implementations are in use today, adaptive streaming bitrate is a method of streaming video over HTTP where the original content is encoded at multiple bit rates, then each of the different bit rates. Bit rate transmissions are segmented into small parts of several seconds. Today’s customer is aware of streams available at different bit rates and stream segments by explicit file. Starting, the client requests segments of the lowest bit rate stream. If the client finds that the download speed is higher than the bit rate of the downloaded segment, then it will ask for the next higher bit rate segments. Later, if the client finds that the download speed of the segment is lower than the bit rate of the segment and therefore the network bandwidth has deteriorated, then it will request a lower segment of the bit rate .
