What is error robustness ?
A. Error robustness means that the encoded audio data can be transported over error prone channels without unacceptable loss in signal quality. MPEG-4 Version 2 realizes this important functionality with two kinds of techniques. One is called “Error Resilience”. The MPEG-4 Audio Version 2 coding algorithms have the ability to generate such error resilient bitstreams that can be decoded with minimal degradation even if they are partially corrupted, if the corrupted part is distinguished. The other technique is called “Error Protection” (see below).
