Configuration
Configuration
The 8990ARC can be configured locally using onboard switches or
remotely using the 8900NET GUI interface or the Newton Control Panel. A
summary of all functions available with each control type along with the
ranges and default values for each parameter is given in
Table 8 on page 26 .
The configuration of the 8990ARC determines:
• Output aspect ratio (16:9/4:3),
• Display conversion modes: (see Output Conversion Modes on page 17 ),
• Bypass (no conversion),
• Pillarbox for 16:9 output or Letterbox for 4:3 output,
• Full Width for 16:9 output or Full Height for 4:3 output,
• 14:9 output,
• High or Low vertical resizing filtering – for vertical black/white or
severe chroma transitions,
• Position of converted outputs on the monitor (Tilt for vertical and Pan
for horizontal positioning),
• Blanking or passing of vertical ancillary data (VANC),
• Number of active video lines selected as data lines (None, 1, 2, or 3),
• Enable one of three Video Index Control modes allowing control from
data within the video input signal,
• Enable one of three Wide Screen Signaling (WSS) Control modes
allowing control from video source data and selection of WSS line (lines
13-27),
• Enable/disable of GPI control,
• Save/Recall of user-defined configurations for each of four GPI and
one non-GPI controlled memory register, and
• Recall of factory default settings.
Output Format Control Summary
The output format from the module can be resized by selecting an aspect
ratio, a conversion mode, and setting vertical resizing.
Output Aspect Ratio
The output aspect ratio can be selected with the web page, Newton control
panel, local controls, or though the GPI registers as either 16:9 or 4:3.
Figure 6 on page 15 and Figure 7 on page 16 illustrate the output conver-
sions for both 4:3 and 16:9 formats.
