Patent ID: 8654251

Claim:
A system or apparatus for producing synchronized digital video data, comprising: a plurality of digital video sources consisting of cameras or image sensors, wherein each is arranged to produce a fraction of the said synchronized digital video data; a clock adapted to set a time period for sampling the synchronized digital video data; a clock distribution subsystem through which the video sources are operably coupled to the clock and adapted to communicate and share the clock between each video source, exhibiting a symmetric delay in transferring the clock to each video source, wherein the video sources are also matched so that they will continue to possess an internal state which is identical in all the video sources, which are therefore synchronized, and will hence exhibit identical behaviour over time, if subjected to equivalent conditions at all times; and a video controller arranged to intercept, filter, sort or marshal all configuration commands directed towards any of the video sources, by halting or disconnecting the clock and restarting or re-connecting the clock, so as to ensure that no such command reaches any of the video sources in a way which upsets the synchronized internal states of the said video sources.
