Video multicast using Network Coding
We investigate the problem of video multicast in lossy networks using network coding and multiple description codes. The rate allocation for multiple descriptions can be optimized at the source to generate a scalable video bitstream such that the expected PSNR of the video at the receivers is maximized. We show that using network coding with multiple description codes can significantly improve ...
متن کاملPipeline Network Coding for Multicast Streams
This paper studies the performance of pipeline network coding for multicast stream distribution in high loss rate MANET scenarios. Most of the previous network coding implementations have been based on batch network coding, where all blocks in the same batch are mixed together. Batch coding requires that the entire batch is received before decoding at destination. Thus, it introduces high decod...
متن کاملDistributed Asynchronous Algorithms for Multicast Network Coding
We propose distributed asynchronous algorithms for network coding in multi-source multicast networks with cycles. Our algorithms find an acyclic subset of connections between links, and set up a network code over these connections. They offer advantages in terms of link usage and coding complexity over previous distributed algorithms based on random coding, while requiring modest additional coo...
متن کاملNetwork Coding for WDM All-Optical Multicast
Network coding has become a useful means for achieving efficient multicast, and the optical community has started to examine its application to optical networks. However, a number of challenges, including limited processing capability and coarse bandwidth granularity, need to be overcome before network coding can be effectively used in optical networks. In this paper, we address some of these p...
متن کاملRate Control for Multicast with Network Coding
Recent advances in network coding have shown great potential for efficient information multicasting in communication networks, in terms of both network throughput and network management. In this paper, we address the problem of rate control at end-systems for network coding based multicast flows. We develop two adaptive rate control algorithms for the networks with given coding subgraphs and wi...
