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 congured by using the Extron
control software for Windows
®
or by using a control system.
Front panel security lockout (executive mode) — To prevent accidental changes to
the unit’s settings, 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 lm. When lm 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 digital video scaler’s advanced
film mode processing 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 dened 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.
Controlling the DVS 304 Devices
All DVS 304 series devices can be controlled using one or more of the following methods:
• 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, and Extron control 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.
