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 FEC scheme comprising the steps of:

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

b. choosing at least three divisors having no common denominators in accordance with a number of data packets in said batch of data packets;

c. organizing into blocks said batch of data packets a number of times in accordance with a number of divisors using said at least three 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 at least one of the at least three divisors is not a common denominator of a number of packets in the designated batch of data packets.

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.
