Using the ARC Function
The SD-ARC Insert parameter under the Video Setup>Processing>
ARC (SD-SDI Out) menu selects a video input source to be processed
by the SD aspect ratio converter. All video output groups using the
video input source selected by the SD-ARC Insert parameter will
automatically have the SD-ARC inserted into their video processing
path. The HD-ARC is always available for HD outputs.
The ARC button provides quick access to the ARC (SD-SDI Out) and
ARC (HD-SDI Out) controls. When the HD video processing block is
currently selected, pressing the ARC button takes you straight to the
ARC (SD-SDI Out) variable controls. When the SD 1, SD 2 or Analog
video proc amp block is currently selected, pressing the ARC button
takes you straight to the ARC (HD-SDI Out) variable controls.
Depending on the video configuration, you must manually select the
appropriate ARC controls to apply the settings to outputs. The
following options are available when the ARC button is pressed:
• Aspect Ratio Lock
•H. Size
• H Position
•V Size
• V Position
The manually adjusted User settings can be saved or recalled from the
four ARC Presets that are available from each ARC (HD-SDI Out) and
ARC (SD-SDI Out) menus.
The X75HD/X75SD also provides viewing modes to allow the quick
selection of predefined input and output aspect ratios.
Note
The ARC mode requires an
HD-SDI module to operate in
both HD-SDI and SD-SDI
formats.
