ADAPTIVE BIT RATE (ABR) STREAMING WITH SERVER SIDE ADAPTATION

摘要

A device for providing adaptive bit rate streaming that includes a first transcoder configured to transcode a video stream based at least in part on an encoding characteristic to generate a first transcoded video stream, a network monitor configured to monitor network conditions including a network bandwidth of a network, an adjustment module configured to cause the transcoder to adjust the encoding characteristic in response to a change in the network conditions, an advertising module configured to advertise to a client device an ABR profile that corresponds to the first transcoded video stream, wherein the advertising module updates the advertised single ABR profile when the at least one encoding characteristic is adjusted, and a network interface configured to transmit segments of the first transcoded video stream to the client device via the network in response to requests therefor.

1. A method for adaptive bit rate (ABR) streaming, the method comprising:
monitoring network conditions of a network; transcoding a video stream to generate a first transcoded video stream, wherein at least one encoding characteristic of the first transcoded video stream is based at least in part on the monitored network conditions; advertising an adaptive bit rate (ABR) profile that corresponds to segments of the first transcoded video stream to a client device via the network; providing the segments of the first transcoded video stream to the client device via the network in response to requests therefor; and adjusting the at least one encoding characteristic of the first transcoded video stream in response to a change in the monitored network conditions.
