Abstract
A computational graceful degradation method is disclosed using priority information in multiple objects case. The method degrades the amount of computation in different ratio every object using the priority information if computational power of a decoder does not come up to that necessary for processing encoded multimedia data as decoding the multimedia data encoded by several objects unit, the priority information being determined by an encoder for optimal graceful degradation in terms of relatively importance between respective objects.
Claims5
A decoding method for media file including a plurality of object data and degradation priority information for each object data comprising the steps of:
- determining the computational power to be allocated for each object data based upon the degradation priority information;
- decoding each object data using the allocated computational power;
- and
- constructing and outputting decoded media using each of the decoded object data.
Media file structure comprising:
- a plurality of audio or visual object data in accordance with MPEG;
- and
- degradation priority information for each object data,
- wherein the degradation priority information indicates a relative importance of each object data.
