A camera (110, 110') is provided that can be connected to a processing system (120, 120') via an external connector (154) outside of the housing of the processing system. The camera (110, 110') includes a camera housing (100). An imaging device (111) is provided inside the camera housing (100) that converts moving pictures to a video signal. A bit rate reduction circuit (115) is also provided inside the camera housing (100) and connected to the imaging device (111). The bit-rate reduction circuit (115) reduces a bit rate of the moving picture signal so as to produce a bit-rate reduced video signal having a lower bandwidth than the video signal prior to bit rate reduction.

Why it's free to use
- Filed August 28, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 28, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 28, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
