Apparatus, methods, and data structures for robuts partitioning and reassembling of video transmission over multipath fading channels is presented. The system is based on a separation of variable-length-coded discrete cosine transform coefficients within each block and is suitable for constant bit rate transmission where the data rate for each proportion is controlled in accordance with its buffer fullness. It is shown that variable-length-coding-based partitioning for INTRA frame blocks can render itself to an accumulation of distortion due to a loss of the second layer, which is overcome by the invention. The propagation of such distortion is shown to be negligible when applied to the ITU-T H263 video coding standard. |
