Open the CIPO recordAbstract From the Canadian patent
An outer decoder and an inner decoder encode a block of information to be transmitted, to improve protection by adding redundancy. The redundancy permits decoding of the information from less than a complete encoded block of information. Time re-alignment of two transmissions of the same content from two base stations can mitigate the problem of duplicated frames. The user of the subscriber station can experience seamless service without repetition of content, even when handing over to a new cell while receiving a buffer of broadcast content.

Why it's free to use
- Filed August 15, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 15, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 15, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
