Open the CIPO recordAbstract From the Canadian patent
A device for controlling image encoding with which target code rates suitable for respective program data can be allocated by using a statistical multiplex technique. A controller (3) receives the encoding difficulties (Di) of programs from image encoders (2i) and calculates temporary bit rates (Tmp_Ratei) in accordance with the encoding difficulties (Di) and the conversion formula of the bit rate. Further the controller (3) corrects the , temporary bit rates (Tmp_Ratei) so that the summation of target bit rates (Target_Ratei) may be within a predetermined allowable value and determines final target bit rates (Target_Ratei) and supply them to the respective image encoders (2i).

Why it's free to use
- Filed July 1, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 1, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 1, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
