Features of the DVS-7300/7350
I/O Expansion System
The DVS-7300/7350 I/O expansion system comprises a DVS-7300/7350
system centered on a DVS-7000A, in combination with a DVS-V6464M or
HDS-X3600 Digital Video Routing Switcher. The primary inputs, signal
matrix, and so on of the DVS-7000A 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, an automatic output 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).
Full-featured video effects
M/E banks
There are three M/E banks, each with equivalent functionality. Each bank
includes two keyers which can be operated independently and
simultaneously.
The output from any M/E bank can be input as a background signal to any
other, for further keying and other operations.
