Abstract :
At present, wireless local area networks (WLANs) supporting broadband multimedia communication are being developed and standardized around the world in the 5 GHz band. Systems such as IEEE802.11a and HIPERLAN/2 will provide data rates up to 54 Mbps. Highly compressed data such as video are extremely sensitive to the errors that are commonly encountered in wireless channels. This paper addresses the problems of transmitting MPEG-2 video over WLANs, and in particular HIPERLAN/2. Error resilient video transcoding is proposed as a means of handling channel errors
