Input Submenu's Advanced Selections - Extron electronics IN1508 User Manual

Input submenu's Advanced selections

Figure 3-22 shows the selections that are available from the Input > Advanced
screen. The switcher automatically adjusts for different input and output modes.
However, if the input signal has slightly different timing or is non-standard, some
settings may need to be manually adjusted. All settings for each input and output
mode (including non-standard input modes) are stored in non-volatile memory so
that the adjustments do not need to be repeated after the settings are optimized.

Figure 3-22 — Input submenu's Advanced selections
To select one of the advanced settings, use the Menu
desired status indicator bar.
Several Input submenu Advanced selections define the active (image) area of the
input (see figure 3-23 on the next page):
• Active pixels — The number of pixels per line that are inside the input active
area. The baseline for the active pixels adjustment is the right edge of the
image. This value is often referred to as horizontal resolution.
• Active lines — The number of lines per frame that are inside the input active
area. The baseline for the active lines adjustment is the bottom edge of the
image. This value is often referred to as vertical resolution.
For interlaced input signals, this variable refers to the total number of lines
per frame after deinterlacing, not the number of lines per field.
• Horizontal start — The number of pixels per line that are inside the blanking
area to the left of the active area.
• Vertical start — The number of lines per frame that are inside the blanking
area above the active area.

The Input submenu's Advanced settings are a comprehensive set of
adjustments to optimize the switcher for non-standard video inputs. Most
users do not encounter such signals. For those users who do, the switcher
automatically adjusts these settings. The switcher's automatic adjustments
are adequate for most inputs.
