Patent ID: 8681865

Claim:
A digital video signal processing system comprising: a video processing unit (“transcoder”) with at least one digital video signal input and at least one digital video signal output, wherein the input video coding format of the transcoder is SVC, wherein the output video coding format of the transcoder is SVC and contains the same temporal, and quality resolutions of the input video coding format and the spatial resolutions of the input video coding format up to and including the one closest (“closest input resolution”) to a desired highest spatial resolution (“desired output resolution”) of the output video coding format, and wherein the transcoder is configured to upsample or downsample the input video signal layer having the closest input resolution to the desired output resolution, as appropriate, and to encode the upsampled or downsampled data using predictors from the coded data of the input video signal layer having the closest input resolution that are appropriately scaled to the desired output resolution and include residuals that are encoded to compensate for the drift introduced.
