Claim:
1. A method of processing multimedia data, the method comprising: receiving an access unit of the multimedia data, the access unit comprising a first section received in error; determining whether the received access unit is uniformly coded or non-uniformly coded, wherein the access unit is uniformly coded when all slices within the access unit are of a same type, and the access unit is non-uniformly coded when slices within the access unit are of different types; obtaining error distribution information that identifies a slice type of a current slice corresponding to the first section, the slice type being of the same type as all slices within the access unit when the access unit is uniformly coded, the slice type is decided based on the available spatially and/or temporally neighboring slice types when the access unit is non-uniformly coded; selecting, based on the error distribution information, an error recovery scheme from the group consisting of frame rate up conversion and temporal error concealment for B-frame; and processing the received access unit using the selected error recovery scheme.
