Patent ID: 8243824

Claim:
An information processing apparatus configured to process a code stream having a first resolution with data having said first resolution scalably encoded, comprising: setting means for decoding a code stream having said first resolution with a second resolution that is lower than said first resolution and setting an authoring area in which to execute authoring by use of decoded baseband data having said second resolution; first creating means for creating a partial baseband data having said first resolution, which is a part of said authoring area, of baseband data having said first resolution obtained by decoding a part of said authoring area of said code stream having said first resolution; authoring means for executing authoring on said partial baseband data having said first resolution; second creating means for scalably encoding said partial authored baseband data having said first resolution to create a partial code stream that is a code stream of said authoring area; and code stream replacing means for replacing said part of said authoring area of said code stream having said first resolution by said created partial code stream.
