Real-time error recovery utilizing layered media multicast control (LMMC)

چکیده
In this paper, we present an optimal solution to the problem of error control in layered and replicated media systems satisfying real-time delay constraints. In doing so, we rely on an apriori estimate of loss along with a hybrid proactive FECARQ scheme to statistically guarantee the quality of service for receivers. Our optimal Layered Media Multicast Control (LMMC) solution to a formulation of the error control problem analytically determines the redundancy assignment of individual groups associated with a layered media system minimizing a cost metric defined over wasted bandwidth of redundancy.

Network-Supported Rate Control Mechanism for Multicast Streaming Media
Layered Multicasting with layered source coding scheme enables efficient distribution of real-time streaming media over heterogeneous networks such as the Internet. In layered multicast, rate control is required to cope with congestion quickly because packet losses in a layer with higher priority lead greater degradation of received quality. In addition, rate control for layered multicast is re...
متن کاملAn Architecture for Multicast Telepresentations
We have developed a scalable reliable multicast architecture for delivering oneto-many telepresentations. Whereas the transport for interactive real-time audio and video is concerned with timely delivery, other media, such as slides, images and animations require reliability. We propose to support reliability by combining multicast with forward error correction (FEC), as well as additional tech...
متن کاملReceiver-driven layered multicast using active networks
This paper proposed a receiver-driven layered multicast scheme using active networks (RLM-AN). The multicast tree is regarded as a set of virtual links. TCP-friendly congestion control and FEC-based error control are performed on each virtual link. In order to solve the loss path multiplicity problem, the intermediate active nodes also perform error recovery. By introducing congestion control a...

The proliferation of video streaming applications that distribute data to a large number of clients motivates the design of fast and reliable multimedia delivery systems capable to adapt effectively to diverse transmission conditions. Receiver-driven layered multicast (RLM) efficiently addresses the issue of heterogeneity in clients’ available bandwidths and packet loss rates by shifting rate c...
متن کاملAdaptive Error Recovery in cdma2000 1xEV-DO Mobile Broadcast Networks
We analyze the performance of MAC-layer Reed-Solomon error-recovery in the cdma2000 1xEV-DO Broadcast and Multicast Services (BCMCS) environment, with respect to the size of the error control block (ECB) and the air-channel condition, and establish the relationship between ECB size, error-recovery capacity and service latency. Real-time traffic, such as voice and video streaming, is very sensit...
