Robust adaptive transmission of data partitioned video

Abstract

In this paper, we first propose a new interlayer synchronization scheme for data partitioned video streams. Unlike conventional schemes, synchronization information is represented as bit position differences between layers and placed in the first layer, which is transmitted via a better channel. Based on data partitioning, we design an adaptive transmission scheme where the source code rate, channel code rate and modulation schemes are changed in an optimal way in response to varying channel conditions.
