Spatial-temporal error concealment with side information for standard video codecs

Error concealment (EC) is important for transmitting video over error prone networks such as the Internet or wireless networks. Different EC strategies have their own advantages for different scenarios. However, it is generally difficult for the decoder to figure out which strategy works the best for a specific case. This paper proposes to use data embedding to convey the necessary high level side information in a standard compliant way to help improve the decoder\´s EC performance. We show that the EC "mode" information (i.e.., whether spatial EC or temporal EC should be used) is critical for a spatial-temporal EC approach.
