Video streaming with diversity

Packet path diversity is one of the recent advances in networkadaptive video streaming. In this paper we first examine two specific techniques for video streaming that exploit diversity to achieve improved performance. The first technique uses a framework for rate-distortion optimized scheduling of the packet transmissions over the available network paths. The second technique exploits feedback and channel probing to determine which network path should be used for transmission and to adapt the source encoding of the video to mitigate error propagation effects. In the final section, we compare the performance of these two techniques by analyzing experimental results and discuss their respective advantages and drawbacks.
