Abstract

We present a robust real-time video coding scheme that complies with the H.263 standard. By utilizing a feedback channel, the corrupted macroblocks (MBs) due to transmission errors are accurately evaluated and precisely tracked in the encoder. Without dependency trees wide-spanning to unnecessary areas, the error propagation effects are terminated completely by INTRA refreshing the affected MBs. Our simulations show significant video quality improvements in error prone environments.
