Input Signal - Extron electronics RGB-DVI 300 User Manual

Input Signal

Video settings
Signal type — RGB or HDTV component (Y, R-Y, B-Y)
Total pixels — The total number of pixels in a line, including blanking on both sides of the
input active area (active, horizontal sync width, back porch, and front porch). The values can
be adjusted from the default value ±512.
NOTE: The total number of lines per frame, including the blanking above and below the
active area is determined by the input signal and is not user adjustable.
Default values for the detected input resolution for total pixels, active pixels, and active lines
are shown with an asterisk (*) in the on-screen display.
Start — The horizontal start defines the number of pixels in the blanking area to the left of
the active area; the vertical start defines the number of lines above the active area.
NOTE: The vertical and horizontal starts and the active area must be set to frame the
active area of the input signal. If these values are set incorrectly, the scaler may
crop trailing edges (right or bottom) or partially mask the leading edges (left or
top).
Active pixels — The number of pixels per line that are inside the active area. The baseline
for the active pixels corresponds to the horizontal resolution of the input signal. The values
can be adjusted from the default value ±512.
NOTE: The active pixels and total pixels adjustments are interactive. Setting one of these
variables may require the other to be adjusted.
Active lines — The number of horizontal lines inside the active area. The baseline for the
active lines corresponds to the vertical resolution of the input signal. The values can be
adjusted from the default value ±256.
Phase — The timing of sampling by the digital scaler. Sampling at the optimum pixel phase
results in a bright, stable output.
NOTE: Total pixels and active pixels must be correctly set before adjusting phase.
Audio settings (RGB-HDMI 300 A model only)
Gain and attenuation — Gain increases audio levels (0 to +10 dB). Attenuation reduces
audio levels (0 to -18 dB).
Audio delay — When video signals are processed, they can be delayed relative to the
audio signal. The RGB-HDMI 300 A automatically delays audio by approximately 15 ms to
compensate for internal video processing. It also allows the user to set an additional audio
delay to compensate for delays to the video signal introduced by other signal processors and
display devices in the system.
