Output Conversion Modes
One of four output conversion modes for either 4:3 or 16:9 output aspect
ratio format can be selected with user controls as follows:
•
For 4:3 format, 1 = Bypass, 2 = Letterbox, 3 = Full Height, 4 = 14:9, or
•
For 16:9 format, 1 = Bypass, 2 = Pillarbox, 3 = Full Width, 4 = 14:9.
Examples of the conversion modes are shown in
for both 4:3 and 16:9 formats.
Control of the desired video output conversion mode can be from four
sources:
•
Web page, Newton Control Panel, or local control,
•
GPI triggering of pre-programmed registers,
•
Video Index Coding data on video input signal, or
•
Wide Screen Signaling (WSS) on input signal.
When set for Remote/Local operation (
Newton Control Panel and local control settings are always enabled and
always valid. GPI controls are based on these settings, stored in GPI regis-
ters, and triggered by the web page, local controls, or an customer-supplied
external device. Video Index Coding and WSS may or may not be valid
depending on the presence of information on the input signal. The status
of both WSS and Video Index Coding is reported at all times for the input
signal on the Settings web page in read-only form (
