Double-Binary Turbo Code for Transmission of Scalable Video Bitstream

Abstract

A novel low bit rate video transmission scheme is proposed for the communication of scalable video bitstream over wireless channel. The schema consists of motion compensated t+2D wavelet decomposition scalable coder and double binary turbo code. Double binary codes were used for protection since they perform better than classical turbo coders in terms of better convergence for iterative decoding, a large minimum distance and computational cost. An efficient method to estimate the minimum distance of double binary turbo codes is also proposed. The best packet length are evaluated by measuring the minimum distance of turbo code to adopt the scalable bitstream with unequal error protection. Simulation results show that the unequal error protection is quite efficient, even in very adverse conditions, and it clearly outperforms simple FEC techniques
