Abstract

We propose a system for wireless video multicast/broadcast to mobile handheld devices. We exploit the latest achievements in video coding (scalable 3D wavelet-based video coder) and in channel coding low-complexity rate compatible punctured PUM-based turbo codes). In the case of severe channel conditions, additional Reed-Solomon coding is applied across the packets. The scalable bitstream is split into multiple frames which are encoded separately. Fast rate optimal algorithms are used to determine suboptimal source channel symbol allocation. Experimental results given for different video sequences and channel conditions indicate good performance achieved at low complexity
