Abstract From the Canadian patent

Disclosed is a system and method that provides rate controlled insertion of asynchronous data into a synchronous stream in a broadcast system. A calculation of the transmission time for an asynchronous data file is determined from the file size, available data transfer rate redundancy , transmission factor, bandwidth scale factor and connect time latency. Transmission time may be employed to schedule transmission of asynchronous data for use at a predetermined time. Transmission time for multiple files may be combined to determine a transmission start time for a first file such that a last asynchronous file is transmitted by a predetermined time.

Why it's free to use

  • Filed March 29, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 29, 2021.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 29, 2023.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
