TIMING PRESETS
In addition to the factory supplied timing presets, users are allowed to save and
recall up to 61 timing presets. Note that Quadra has a common timing list that
can be applied to either input or output ports.
There are three ways to create a timing preset entry. The first two are listed
immediately below. Note that they store a limited number of timing parameters
as listed in the “Timing Preset” list below.
• Output timing — Timing presets may be created by saving output
timing settings using the
OutPutTiMingSAVE command.
• Direct loading — Timing presets may be created by directly loading
them using the TiMingLISTLOAD
command.
Timing presets contain the following parameters:
• Timing preset name
• Horizontal front porch, sync width, back porch, and active area (in
pixels)
• Vertical front porch, sync height, back porch, and active area (in lines)
• Horizontal and vertical frequencies
• Sync format
• Horizontal and vertical sync polarities
• Interlace
Timing presets that were created by saving input timing with the INputSAVE
command will contain all of the above settings — in addition to the following
supplemental parameters:
• ADC sample phase
• De-interlacer mode
• ADC gain and offset values for Red, Green, and Blue channels
• Brightness, Contrast, Hue, Saturation, Filter settings, Aspect Ratio and
Over/Underscan mode
