FOR-A HVS-490 - Selecting Video Sources

67
9-2. Selecting Video Sources
Bus button rows on the control panel facilitate video source selection in the switcher.
A single bus row comprises 18 bus buttons for HVS-492OU units, 22 for HVS-492WOU and 12 for
HVS-492ROU and an M/E has three bus rows: PGM, PST and KEY/AUX for M/E1 and PGM, PST
and KEY/FLEX for M/E2.
Button and video source assignments can be freely set and changed. In addition, each button can
be inhibited to prevent operational mistakes.
Button and video signal assignments are shared by all M/Es, although different assignments for
each M/E is also allowed.
► See Sec. 6-2. “Mapping Video Sources to Bus Buttons.”
9-2-1. M/E Bus Type
An M/E bus has two bus rows: PGM and PST (when set to P/P: factory default setting).
The PGM bus is the upper row and outputs program (on-air) video.
The PST bus is the bottom row and outputs the next video.
The BUS TYPE can be selected for each M/E under BUS TYPE in the [SETUP > SYSTEM >
BUS TYPE] menu from the following three options.
P/P (PGM/PST)
(Default)
Source selections in the PGM and PST buses are switched when transitions occur
and users can always select the next background signal (PST image) in the bottom
row.
A/B
Source selections in the PGM and PST buses do not switch when transitions occur
and the next signal must be selected in the accompanying bus after each transition.
P/P Reverse
PST/PGM mode. PGM and PST buses are placed in the reverse order of
P/P(PGM/PST) and users can always select the on-air background signal (PGM
image) in the bottom row.
