Abstract
A method for characterizing performance of an error correction scheme for digital data transport is provided. A digital data packet stream within an Internet Protocol packet stream is monitored for a first set of packet errors. Errors of the Internet Protocol packet stream are corrected according to the error correction scheme to produce a corrected Internet Protocol packet stream. The digital data packet stream within the corrected Internet Protocol packet stream is monitored for a second set of packet errors. The first and second sets of packet errors are compared to characterize the performance of the error correction scheme.

A method for characterizing performance of an error correction scheme for transport of digital video data, comprising:
- monitoring a digital video data packet stream comprising transport stream packets of the digital video data within an Internet Protocol packet stream for a first set of continuity count errors of the transport stream packets;
- correcting errors of the Internet Protocol packet stream according to the error correction scheme, thus producing a corrected Internet Protocol packet stream;
- monitoring the digital data packet stream within the corrected Internet Protocol packet stream for a second set of continuity count errors of the transport stream packets;
- and
- comparing the first set of continuity count errors and the second set of continuity count errors to characterize the performance of the error correction scheme.
A system for characterizing performance of an error correction scheme for transport of digital video data, comprising:
