Feedback aided content adaptive unequal error protection based on Wyner-Ziv coding

In prior work, we proposed an unequal error protection algorithm based on Wyner-Ziv coding for error resilient video transmission. In subsequent work it was demonstrated that using either of content adaptive unequal error protection or feedback 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.
