Abstract

Methods and apparatus to process multimedia data enabling faster channel acquisitions, improved error recovery and improved efficiency. An encoder device encodes a first portion of multimedia data using inter-coding to generate a first version, and encodes the first portion of multimedia data using intra-coding to generate a second version. A decoder device receives a first version of a first portion of multimedia data, wherein the first version is inter-coded, receives a second version of the first portion of multimedia data, wherein the second version is intra-coded, and selectively decodes the first and second received versions.
