16.7. Version 2 Error-Robustness Test
As explained in the previous section, the MPEG-4 Audio Version 2 verification tests included three coding efficiency subtests and two error-robustness subtests. In Section 16.6, the coding efficiency test was addressed. This section deals with the error-robustness test.
The evaluation of error robustness implied a comparison between the perceived quality of a stream corrupted by transmission errors against the perceived quality of the same stream when uncorrupted. For this, it was essential to select relevant channel conditions.
16.7.1. Test Conditions
All natural speech and audio coding tools included in the MPEG-4 Audio standard allow for error-robust operation by means of their error-resilient bitstream ...
