Cinde 2BG Video Priority Switcher/Black Generator
The CInde 2BG is an extremely useful device with wide application. Essentially
a video sync detector and black raster generator, the 2BG has two external video
inputs (Video and Aux), providing 4 operating modes (selectable by front panel switches):
Priority mode 1: Video output follows video input, defaults to generated black if video disappears
Priority mode 2: Video output follows video input, defaults to Aux input if video disappears
Override mode 1: Outputs AUX signal at all times
Override mode 2: Outputs generated black at all times
The generated signal is PAL black raster (no colour burst).
