Abstract
A method and apparatus of processing multimedia data that includes a first section received in error are disclosed. Error distribution information corresponding to the first section may be obtained. One of a plurality of error recovery schemes may be selected based on the error distribution information for the first section. The selection may be based at least on whether a channel switch is detected. The first section may be processed based on the selected error recovery scheme.

A method of processing multimedia data comprising a first section received in error, the method comprising:
- obtaining error distribution information corresponding to the first section;
- selecting one of a plurality of error recovery schemes based on the error distribution information for the first section, wherein the selecting is based at least on whether a channel switch is detected;
- and
- processing the first section based on the selected error recovery scheme.
An apparatus for processing multimedia data comprising a first section received in error, comprising:
- means for obtaining error distribution information corresponding to the first section;
- means for selecting one of a plurality of error recovery schemes based on the error distribution information for the first section, wherein the selecting is based at least on whether a channel switch is detected;
- and
- means for processing the first section based on the selected error recovery scheme.
A processor configured to perform a method, the method comprising:
- obtaining error distribution information corresponding to a first section of multimedia data received in error;
- selecting one of a plurality of error recovery schemes based on the error distribution information for the first section, wherein the selecting is based at least on whether a channel switch is detected;

- processing the first section based on the selected error recovery scheme.
A computer-readable medium embodying means for causing a computer to execute a method, the method comprising:
- obtaining error distribution information corresponding to a first section of multimedia data received in error;
- selecting one of a plurality of error recovery schemes based on the error distribution information for the first section, wherein the selecting is based at least on whether a channel switch is detected;
- and
- processing the first section based on the selected error recovery scheme.
An apparatus for processing multimedia data comprising:
- a receiver configured to receive the multimedia data having a first section received in error;
- and
- an error concealer comprising:
- a selecting module configured to select one of a plurality of error recovery schemes based on the error distribution information for the first section, wherein the error concealer is configured to apply one of the plurality of error recovery schemes based at least on whether a channel switch is detected;
- and
- a processing module configured to process the first section based on the selected error recovery scheme.
