At present, Wireless Local Area Networks (WLANs) supporting broadband multi
media communication are being developed and standardized around the world i
n the 5GHz band. Systems such as IEEE802.11a and HIPERLAN/2 will provide da
ta 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 propose
d as a means of handling channel errors.
