RS-170 and NTSC Video Front Ends

We have circuit designs to phase-lock to analog RS-170 and NTSC video signals, digitize the video data, and write the data to a processor's memory using Direct Memory Access (DMA).

Video Multiplexing and Distribution

Our video multiplexing circuits include an 16-input, 16-output 200MHz BW crossbar switch.  The crossbar switch can be combined with fiber optic transceivers for video and serial data distribution to over 10,000 ft. distance between stations.

Video Graphics

Whether you call it graphics, overlay, marks, or annotation, our embedded control algorithms may be just what you are looking for.  Alpha-numeric characters, bit-mapped, special graphics, reticles, crosshairs, etc.  We have design experience marking video in real-time, for dynamic graphics effects, marking moving objects and displaying dynamic numerical information at video refresh rates.

Control of Video Recorders

North Star has developed unique controls for standard VHS and DV video recorder/players.  By modifying the electronics inside the decks, we can control the mechanisms for video editing, reading time code information, and starting and stopping the deck precisely on a time code for editing and replay purposes.  We have developed both wired and wireless (900 MHz) versions of handcontrollers to go with these decks.
