A digital compressed video signal transmission system includes a transport processor (FIG. 7) for segmenting (105,115) compressed data into transport cells for transmission. Particular portions of the compressed data are formatted (110,120,125) into further transport cells, which further transport cells are interspersed with normally occurring transport cells. The further transport cells include redundant video signal data which may be utilized to resynchronize a compressed video signal decoder after loss or corruption of transmitted data.

Why it's free to use
- Filed May 20, 1993 and granted March 18, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 20, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 20, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
