Theory of Operation

VBOB is a digital video switcher that routes video inputs from different sources to
various output formats. VBOB inputs include Serial Digital Standard Definition (SD) and
High Definition (HD) BNC connectors, a Low Voltage Differential Signaling (LVDS)
video input connector, and an optional dual-link Transition Minimized Differential
Signaling (TMDS) input. VBOB outputs include dual-link Serial Digital Standard
Definition and High Definition BNC connectors, which you can use with applications
where Alpha signals accompany the YUV video. In addition, VBOB includes an LVDS
video output connector. Generator Locking Device (Genlock) input and loop-throughs
for both Standard Definition Video and High Definition Video, and a RS-232 port for
system upgrading and maintenance are also included.

Utilizing a highly advanced 80-bit parallel video crossbar, you can configure VBOB for
various I/O applications. VBOB complies with the following standards:

•

High Definition SMPTE-292M

•

Standard Definition SMPTE-259M

Note:

HD and SD have separate connections, which allows you to switch between

operational domains without switching cables.
