Joint source and channel rate control in multicast layered video transmission

چکیده
Delivering temporally-constrained multimedia streams in heterogeneous environments, ooering no guarantee in terms of bandwidth, packet loss, or delay, is a a very challenging problem faced today by both the networking and the coding community. Layered coding is often proposed as a solution for rate-based congestion control of video transmission in heterogeneous environments. The problem addressed more speciically here is the design of a responsive mechanism for rate allocation in each layer, that would guarantee the best bandwidth usage for all the receivers. After a review of solutions for congestion and loss control in unicast video communications, the paper describes a rate-based congestion control mechanism for multicast layered video transmission.

Source and Channel Adaptive Rate Control for Multicast Layered Video Transmission Based on a Clustering Algorithm
This paper introduces source-channel adaptive rate control (SARC), a new congestion control algorithm for layered video transmission in large multicast groups. In order to solve the well-known feedback implosion problem in large multicast groups, we first present a mechanism for filtering RTCP receiver reports sent from receivers to the whole session. The proposed filtering mechanism provides a...
متن کاملBandwidth Allocation for Layered Multicasted Video
Some type of transmission rate control protocol is required in order to support multicast video applications over the Internet. Previously, researchers have proposed two basic families of control protocols. The first, sender based rate-adaptation, focuses on the sender. The sender uses a single channel to transmit the video signal to all receivers, and the sender adjusts the transmission rate o...
متن کاملFEC and Pseudo-ARQ for Receiver-Driven Layered Multicast of Audio and Video
We consider the problem of joint source/channel coding of real-time sources, such as audio and video, for the purpose of multicasting over the Internet. The sender injects into the network multiple source layers and multiple channel (parity) layers, some of which are delayed relative to the source. Each receiver subscribes to the number of source layers and the number of channel layers that opt...
متن کاملCombined wavelet video coding and error control for Internet streaming and multicast
This paper proposes an integrated approach to Internet video streaming and multicast (e.g., receiver-driven layered multicast (RLM) by McCanne) based on combined wavelet video coding and error control. We design a packetized wavelet video (PWV) coder to facilitate its integration with error control. The PWV coder produces packetized layered bitstreams that are independent among layers while bei...

Some type of transmission rate control protocol is required in order to support multicast video applications over the Internet. Previously, we proposed a new protocol, the Layered Multicast Control Protocol (LMCP), which utilizes both the video sender and the receivers to control the rate of the video transmission. One weakness of this approach is that feedback from all receivers is required in...
