[AVT] Generic FEC how many packets can be recovered



Hi,

 

This may be well understood to FEC experts, but I’m new to this area.

The FEC proposal provides protection for a set of RTP packets, lets say sequence numbers 2 through 10.

If packets, 4, 5, and 6 are lost.  Can this FEC scheme recover ALL the lost packets?  Or is this algorithm only able to recover ONE lost packet in the sequence.

 

If so, the recovery text in the draft could be enhanced to detail how this would be accomplished.

 

Thanks

Brad
