Abstract:
The present invention relates to an encoder, transcoder and methods thereof. A transcoder embodiment involves transcoding a bitstream representing an original video source from an input video format to an output video format. An encoder embodiment involves providing transform coefficients in side information related to an encoded video bitstream.

Claim (Index 33):
A non-transitory computer-readable storage medium comprising a computer program product including instructions to cause at least one processor to:\n receive the bitstream with the input video format, wherein the input video format is a first video format; receive side information related to said video bitstream, said side information comprising at least:\n a video bitstream representing the original video source with a second video format, \n coding parameters based on knowledge of the original video source; and \n transform coefficients, indicative of a residual between original transform coefficients and estimated transform coefficients; \n decode said received side information to generate transcoding guiding information; estimate a representation of said bitstream and transform coefficients with a second video format based on the received bit stream with first video format and the generated transcoding guiding information; determine a first set of transform coefficients from the estimated transform coefficients wherein the first set of the transform coefficients captures the main characteristics of the original transform coefficients; determine a second set of transform coefficients from the side information wherein the transform coefficients of the second set corresponds to same positioning within a transform block as the transform coefficients of the first set; add the second set of transform coefficients to the first set of the transform coefficients, to create refined transform coefficients that better captures the characteristics of the original transform coefficients than the estimated transform coefficients; and encode the estimated representation of said received bitstream with the second video format using the created refined transform coefficients.
