Chapter 1 Overview
The DVS-7250 I/O expansion system comprises a DVS-7250 system
centered on a DVS-7200A, in combination with a DVS-V6464M or HDS-
X3600 Digital Video Routing Switcher. The primary inputs, signal matrix,
and so on of the DVS-7200A are replaced by the DVS-V6464M or HDS-
X3600, thus increasing the number of inputs and outputs.
Features
Support for large-scale live systems
Wide range of inputs and outputs
This system supports a wide range of inputs and outputs, including 60
primary inputs, 28 auxiliary outputs, and five assignable outputs. It is ideal
for use in a large outside broadcast vans and large live productions using
substantial numbers of cameras, VTR materials, and monitor feeds.
Source assignment at the video and key levels
The source assignment to cross-point button selections introduces the concept
of video level and key level; by means of a virtual level of key source
assignment to buttons, more efficient source assignment is possible. The
AUTO SELECT function (linking the video source and key source) also
follows these settings.
Full range of preview functions (AUTO PVW2, SHOW KEY)
When an M/E PVW (mix/effect preview) or PST (preset) is selected on the
EDIT PVW (edit preview) bus, with the on-air status of the output video, an
automatic switch to the M/E PGM or M/E PVW signal can be made
according to the on-air status of the M/E or crosspoint selections on the PGM
and PST buses (AUTO PVW2). Also, with a simple button operation the key
source selected on an M/E keyer can be output to EDIT PVW (SHOW KEY
function).
