A new error correction block based Hybrid ARQ protocol, in which PHY layer packets are composed of multiple error correction blocks, is devised together with a retransmission control scheme constructed on the basis of these error correction blocks. This protocol is designed dedicatedly for mobile AV stations to provide the high quality digital video transmission through a radio channel. To analyze the performance of this protocol, the frame loss rate vs. the uncorrectable error probability is simulated, in comparison with the ordinary packet based retransmission control. A wireless video transmission system using IEEE802.11b PHY is also described, which has been developed with the use of a Medium Access Control (MAC) LSI to perform the proposed protocol.
