Abstract

In prior work, we proposed an unequal error protection algorithm based on Wyner-Ziv coding for error resilient video transmission. In subsequentwork it was demonstrated that using either of content adaptive unequal error protection or feed-back aided unequal error protection individually improved error resilience performance. In the current paper we propose to combine the use of a content adaptive function, implemented at the encoder, with the channel loss feedback provided by the decoder. The experimental results demonstrate improved rate distortion performance.
