Abstract:
An example method includes receiving a video bitstream with a high fidelity input format and side information related to the video bitstream. The side information includes a video bitstream representing the original video source with a low fidelity input format, coding parameters optimized based on knowledge of the original video source, transform coefficients, indicative of a residual between the original video source and a decoded version of the high fidelity format. The method further includes decoding the side information to generate transcoding guiding information, estimating a representation of video bitstream with a low fidelity output format, based on the received bit stream and the generated transcoding guiding information, improving the estimated low-fidelity representation by adding the transform coefficients of the side information to transform coefficients generated from the estimated low-fidelity representation, and encoding the improved estimated representation of the low-fidelity bitstream.

Claim (Index 1):
A method for a transcoder arrangement of transcoding a bitstream representing an original video source from an input format to an output format, comprising\n receiving the bitstream with the input video format, wherein the input video format is a high fidelity format; receiving side information related to said video bitstream, said side information comprising at least: a video bitstream representing the original video source with a low fidelity input video format, coding parameters optimized based on knowledge of the original video source, and transform coefficients indicative of a residual between the original video source and a decoded version of the high fidelity format; decoding said received side information to generate transcoding guiding information; estimating a representation of said bitstream with a low fidelity output format, based on the received bit stream and the generated transcoding guiding information adding the transform coefficients of the side information to transform coefficients generated from the estimated representation of said bitstream with the low fidelity output format, to improve the estimated representation of said bitstream with the low fidelity output format; and encoding the improved estimated representation of said bitstream with the low fidelity output format.
