Abstract

This paper has a threefold goal. First an error resilience technique based on UEP-FEC, proposed by the authors in a previous work, is extended to incorporate a more efficient, adaptive, intra refresh mechanism based on an error-sensitivity metric representing the vulnerability of each coded block to channel errors. Second, the validity of the UEP technique for video transmission over a WCDMA channel is evaluated, thus extending the range of applicability of the above technique, which was originally conceived for and validated on DECT, slow fading, channels. Third, by elaborating on experimental evidence, we prove again that a final judgement on which is the best performing resilience strategy can not be given, without taking into account channel conditions, especially the Doppler spread value.
