VIDEO IN AND OUT
Connect a source of composite analog (NTSC or PAL-B) video to either or both BNC's labeled ANLG A/
ANLG B. Connect a reference black signal to the REF IN BNC. Decoded video with embedded audio is
available on the SDI OUT (1A/2A), (1B/2B) BNC's, two for each channel. Decoded and re-encoded analog
video with control text is available on the MON OUT output BNC. If the module is not present or the power
is off, there will be nothing on any of the outputs. The module is designed to support simultaneous
decoding of two video signals of the same format.
