Controlling the DVS 304 Devices

All DVS 304 series devices can be controlled using one or more of the following methods:
•
•
•
•
•
Buffered video outputs —
DVS 304 models – Five rear-panel BNC connectors and one VGA-type 15-pin HD
•
connector provide connections for RGB or Y, R-Y, B-Y output. Both outputs are
active at all times for simultaneous output.
DVS 304 DVI models – Five rear-panel BNC connectors and one DVI-I connector
•
provide analog and digital output (DVI-I) and analog output (BNC). All outputs are
active at all times for simultaneous output of RGB or Y, R-Y, B-Y. DVI-D output is
disabled for RGB pass-though.
Device control — The scaler has four methods of control: by its front panel, via a
computer or other RS-232/Ethernet control device, using the optional IR 902 remote
control, or via the Signal Processing Products Control Program (SPPCP).
Scaled outputs — The DVS 304 models offer 69 output rates and the DVS 304 DVI
models offer 70 output rates.
RS-232 configuration — All DVS 304 series units can be configured by using the
Extron control software for Windows
Front panel security lockout (executive mode) — To prevent accidental changes
to the settings on the unit, the scaler provides front panel lockout of all controls
except input switching. A second executive mode completely disables all front panel
controls.
3:2 pull down detection for NTSC and 2:2 film detection for PAL video
sources — These patented, advanced film mode processing features help maximize
image detail and sharpness for video sources that originated from film. When film is
converted to NTSC video, the film frame rate has to be matched to the video frame
rate in a process called 3:2 pull down. "Jaggies" and other image artifacts can result if
conventional de-interlacing techniques are used on film-source video. The advanced
film mode processing on the digital video scaler recognizes signals that originated
from film. The scaler then applies video processing algorithms that optimize the
conversion of video that was made with the 3:2 pull down process. This results in
richly detailed images with sharply defined lines. A similar process is used for PAL
film-source video.
Versatile mounting options — The non audio models are 1U high, half rack wide
rack mountable devices. Alternatively, they can be placed on a table or other furniture.
Rubber feet are included.
The audio models are 1U high and full rack size and can be rack or desk mounted
using included rack or through-desk mounting brackets.
The front panel controls.
A computer, a touch screen panel, or any other device that can send and receive
the serial communications through the RS-232 or Ethernet port. The Extron Simple
Instruction Set (SIS ) is a set of simple keystroke commands that can be used with
™
any such devices,
Extron Signal Processing Products Control Program (SPPCP) software for Windows
provides a graphical interface for controlling the scaler from a computer.
The optional IR 902 remote control, replicating most of the front panel controls.
Ethernet control via IP Link, enabling the scaler to be controlled and actively
monitored over a LAN, WAN, or the Internet.
or by using a control system.
