According to one aspect of the present invention, a method and apparatus
is provided in which input data (e.g., input video data) is encoded in
accordance with a first coding standard (e.g., MPEG-4) to generate
encoded data. The input data is also encoded based on a reconstruction of
the input data to generate encoded side information associated with the
input data. The encoded data are transmitted to a destination (e.g., a
decoding subsystem) over a first channel and the encoded side information
are transmitted to the destination over a second channel. The encoded
data and the encoded side information are decoded and combined at the
destination to generate output data.
