Abstract
This paper proposes a number of video transcoding techniques for the purpose of adding error resiliency. The proposed solutions make use of distributed video coding technologies which were originally reported in the literature for distributing coding complexity between the encoder and the decoder. Three transcoding solutions are proposed: frequency-domain, time-domain and compressed-domain transcoding, and various decoding architectures are investigated. Error resiliency at the decoder is addressed as a post-process, an integrated process and a pre-process. It is shown that implementing error resiliency as a decoder pre-process and combining this with compressed-domain transcoding removes the need to interfere with the functionality of existing and compliant decoders whilst minimising complexity. The proposed solutions serve as a framework for boosting the error resiliency of pre-encoded video and can be applied to MPEG-2, and H.264/AVC coded streams.
