6. A method for a closed-circuit internet protocol (IP) network, comprising:
- comparing a pre-selected loss period for at least some packets in an internet protocol (IP) transmission, to a first-observed loss period in the IP transmission;
comparing a pre-selected loss distance between two spaced-apart loss-period packets in the IP transmission, to a first-observed loss distance in the IP transmission; and
at least one of;
instructing an FEC transmitter-generator to generate a first loss period that is proportional to the first-observed loss period; and
instructing the FEC transmitter-generator to generate a first loss distance that is proportional to the first-observed loss distance.
