Abstract

A method includes organizing a first media source block in the media container file; calculating forward error correction (FEC) redundancy data based on the first media source block; organizing the FEC redundancy data in at least one FEC reservoir in the media container file; providing, in the media container file, meta data providing an association between the first media source block and the at least one FEC reservoir; storing the first media source block as a first elementary item in the media container file; and providing, in the media container file, information that the first elementary item comprises the first media source block

Claims

1. A method of generating a media container file, comprising:

organizing a first media source block in the media container file;

calculating forward error correction (FEC) redundancy data based on the first media source block;

organizing the FEC redundancy data in at least one FEC reservoir in the media container file;

providing, in the media container file, meta data providing an association between the first media source block and the at least one FEC reservoir;

storing the first media source block as a first elementary item in the media container file; and

providing, in the media container file, information that the first elementary item comprises the first media source block.

2. The method of claim 1, further comprising:

providing a media source file; and

organizing the media source file into the first media source block and any number of other media source blocks.

3. The method of claim 2, wherein the first media source block more than one contiguous portion of the media source file.

4. A media content server, comprising:

a media block manager for organizing a first media source block in the media container file;

a forward error correction (FEC) codec for calculating FEC redundancy data based on the first media source block;

an FEC data manager coupled to the FEC codec for organizing the FEC redundancy data in at least one FEC reservoir in the media container file;

a meta data manager for providing, in the media container file, meta data providing an association between the first media source block and the at least one FEC reservoir;

a media container file manager for storing the first media source block as a first elementary item in the media container file; and

a media source block information manager for providing, in the media container file, information that the first elementary item comprises the first media source block.

5. An apparatus, comprising:

a processor; and

a memory unit communicatively connected to the processor and including;

computer code for organizing a first media source block in the media container file;

computer code for calculating forward error correction (FEC) redundancy data based on the first media source block;

computer code for organizing the FEC redundancy data in at least one FEC reservoir in the media container file;

computer code for providing, in the media container file, meta data providing an association between the first media source block and the at least one FEC reservoir;

computer code for storing the first media source block as a first elementary item in the media container file; and

computer code for providing, in the media container file, information that the first elementary item comprises the first media source block.

6. A program product, embodied on a computer-readable medium, comprising computer code for performing the following steps:

organizing a first media source block in the media container file;

calculating forward error correction (FEC) redundancy data based on the first media source block;

organizing the FEC redundancy data in at least one FEC reservoir in the media container file;

providing, in the media container file, meta data providing an association between the first media source block and the at least one FEC reservoir;

storing the first media source block as a first elementary item in the media container file; and

providing, in the media container file, information that the first elementary item comprises the first media source block.
