1. A method for processing an input digital video signal, encoded in a scalable video coding format that supports one or more of spatial and quality scalability in order to produce an output digital video signal at an intended resolution, the method comprising:

  • for the output signal, replacing information in a plurality of scalable layers of at least one input video signal lower than a target layer that corresponds to the intended resolution such that information not required to decode the output video signal at the intended resolution is replaced by information that requires fewer bits in the output video signal, and wherein the output video signal with the replaced information is still conforming to the scalable video coding format, wherein a side information input data enables the replacement of the information not required to decode the output video signal at the intended resolution of the side information input data without fully parsing the entire input video signal.
