ABSTRACT:
Methods for scaling (e.g., transcoding) data are described. A sequence of encoded data is accessed. The encoded data are organized according to an encoding scheme that was used to encode the data. A value for a scalable attribute is ascertained. The scalable attribute identifies how the encoded data are to be scaled. A reference to segments of encoded data associated with the scalable attribute is accessed. The reference is beyond the syntax of the encoding scheme. The reference is used to locate the segments in the sequence of encoded data. The segments are found without requiring knowledge by the device of the encoding scheme. A scaled version of the encoded data is created using the segments.
