We propose two error resilient techniques for transmission of compressed video over error prone scenarios. The first technique is an improvement on the generalized source channel prediction (GSCP) scheme proposed by Yang and Rose in 2006. The second technique is a modification of weighted prediction (WP) present in the H.264 standard. Both techniques provide greater emphasis on Intra MBs during the formation of a reference frame thereby achieving better error resilience than GSCP with a very modest increase in the bit-rate.
