....number of layers means smaller bandwidth for each layer, and hence finer adaptation granularity on the receiver s side. The drawback here is that more layers will bring more overhead (for both coding and transport) which diminishes the benefits from the improved granularity in adding more layers [4,12]. Another issue is that, under a typical wireless broadcast environment, receivers capacities generally exhibit some kind of clustered distribution instead of uniform distribution. This is because receivers usually use some standard access interfaces. Therefore, if the bandwidth allocation among ....

....central point has complete knowledge of the capacity constraint for each receiver in each session. In our system model, we use channel as the basic unit for bandwidth allocation. A channel in a wireless system The overhead depends on the number of layers as well as the bandwidth of each layer [4,12]. represents a fixed unit for data transmission, e.g. a time slot in TDMA systems, a frequency in FDMA systems, or a logical allocation unit such as the logical channel in WCDMA [1] We further assume that each video layer can occupy only an integral number of channels, and a receiver s capacity ....

.... a small playback delay also provides the server the opportunity to retransmit lost video packets before their decoding deadline [8, 13] Longer time scale bandwidth fluctuations, on the order of a few seconds to tens of seconds, can be addressed by using multiple versions of the same video [4] or a layeredencoded video [14] When using a layered encoded video, the application needs adaptive control policies to decide which layers should be streamed at all times [11, 9, 15] in order to maximize the overall quality of the video rendered to the user. In this paper, we study the streaming ....

....we compare distributing video versions to distributing video layers. We also examine mixed strategies consisting of both versions and layers. Broadly speaking, we find that mixed strategies that use both versions and layers provide the most robust performance. 1.1. Related Work De Cuetos et al. [5] and Kim et al. [6] also compared streaming of video versions to streaming of video layers. However, they focused on time dependent streaming of a single video from origin server to client; they did not take into account an intermediate cache sitting between origin servers and clients. ....
