Description: We study the optimal streaming of variable bit-rate (VBR) video over a random VBR channel. The goal of a streaming application is to enable the successful decoding of each video object before its displaying deadline is violated. Previous literature has described solutions to estimate the interruption-free probability by assuming either independence in the encoded data process or simplistic channel models. In this thesis, we first present an analytical framework to bound the probability of un-interrupted playback. When a Markov VBR channel model is available, we quantify the distribution of the number of interruptions under the constraint of initial playback delay, receiver buffer size and different recovering schemes. Both the infinite and finite buffer cases are considered. Experimental results with MPEG-4 VBR encoded video validate our analysis. Finally, we show that the proposed analysis provides a theoretical foundation to quantify the tradeoffs between different system parameters.
