Abstract

The present invention relates to a method for optimizing the FEC scheme comprising the steps of: (a) receiving a batch of data packets designated for transmission; (b) choosing a number of divisors having no common denominators in accordance with the said batch of data packets; (c) organizing into blocks said batch of data packets a number of times in accordance with the number of divisors using said divisors; and (d) creating a FEC packet for each of said blocks.

Claims (12)

1. A method for optimizing a forward error correction (FEC) scheme comprising the steps of

a. receiving a batch of data packets designated for transmission;

b. choosing a number of divisors having no common denominators with one another, a number of packets in the batch not being divisible by at least one divisor of the number of divisors;

c. organizing into blocks said batch of data packets a number of times in accordance with the number of divisors using said divisors; and

d. creating a FEC packet for each of said blocks.

2. The method according to claim 1 further comprising the steps of

e. transmitting the designated batch of data packets together with the created FEC packets to a receiver; and

f. recovering lost data packets of said designated batch of data packets using said created FEC packets at said receiver.

3. The method according to claim 1 , where the divisors are 5, 7, and 9.

4. The method according to claim 1 , where the divisors are 5, 6, and 7.

5. The method according to claim 1 , wherein the number of divisors is at least three.

6. The method according to claim 5 , wherein the designated batch of data packets includes packets from a previous designated batch of data packets, the number of data packets from the previous designated batch of data packets corresponding to a remainder for a number of data packets in the previous designated batch of data packets divided by the at least one of the at least three divisors that is not a common denominator of the number of packets in the previous designated batch of data packets.
