Abstract:
1. A method of processing bi-directionally predicted multimedia data comprising a first section received in error, the method comprising: identifying, by a decoder hardware device, a first forward reference section and a first backward reference section based upon a determination of motion vectors associated with regions of the first forward reference section and the first backward reference section, such that the regions, when moved along the respective motion vectors, overlap regions of the first section received in error, wherein the first forward reference section is contained in a forward reference frame, and wherein the first backward reference section is contained in a backward reference frame; determining, by the decoder hardware device, temporal prediction data for the first section received in error, wherein the temporal prediction data corresponds to the first forward reference section and the first backward reference section; and estimating, by the decoder hardware device, the first section received in error based on at least one of the first forward reference section and the first backward reference section.
