Congestion Control for Scalable VBR Video with Packet Pair Assistance

Abstract: The SVC (Scalable Video Coding) extension to the recent video compression standard H.264/MPEG-4 AVC paves the way for video congestion control, by allowing flexible on-thefly adjustments of the sending rate. We study the interaction between TFRC (TCP-Friendly Rate Control) and application level rate control, and observe that TFRC requires relatively large router buffers to keep packet loss on acceptable levels. In turn, this leads to increased jitter which excludes delay sensitive applications. As a response, … Show more

“…In an SVC based admission control mechanism, the option exists to not only block the request but to allow a new request at a reduced video quality level [14,15] when congestion is imminent. This approach can force the video to switch to a lower video quality level but still requires other, more traditional, admission control mechanisms to block sessions when even the lowest quality level cannot be admitted anymore.…”
