26 X75HD/X75SD Installation and Operation Manual
Chapter 1: Introduction
The controls for those processing blocks are located in the submenu
located at Video Setup>Processing, and will appear automatically as
the respective hardware and software options are installed.
Default (Auto Detect) vs. Video Routing and Simulcast
Modes
There are two main operational modes for defining the input video:
M-Path (multiple-path) processing, and Simulcast processing. A third,
Auto Detect, is the default mode.
X75HD/X75SD units are shipped with Auto Detect video mode as the
factory default setting. This mode sets the X75HD/X75SD to
automatically detect analog, SD1, SD2, HD-F, HD1, HD2, composite,
and S-video inputs. When video is connected to any of these inputs, the
X75HD/X75SD automatically selects the applied input video and then
sends the converted video to all outputs. The Video Input LEDs on the
front panel show the selected video source.
In the video routing mode, an output is selected, and then the input to be
processed to that output is selected. Depending on the configuration, up
to four paths can be set up.
To operate an X75HD/X75SD frame in Simulcast mode (where any two
inputs are selected to switch simultaneously between determined
outputs, such as SDTV and HDTV), you will need to set up the unit to
process signal information differently. To do this, see “Simulcast
Operation” on page 32.
For more information on the conversion capabilities and options
provided by the X75HD/X75SD, see “HD Conversion Capabilities” on
page 349.
