Extron electronics SMP 300 Series User Manual page 52

Use the left ([) ADJUST knob to select the desired input. Us the right ({) ADJUST knob to
toggle AUTO IMAGE ON or OFF (default).
When enabled and a new input frequency is detected, an existing Auto Memory for the
signal is applied (if AUTO MEMORY is enabled). If no entry exists, an automatic Auto‑Image
is applied to the new signal. This sizes and positions the incoming video signal to display
properly within the channel window, with respect to the current aspect ratio setting.
The value is global to all analog inputs on the SMP 300 Series and defines the minimum
luminosity that the Auto‑Image routine defines as active video (default: 25%).
Auto‑Image affects active pixel, active lines, H/V start, and phase configurations. All other
picture controls remain unchanged. If the aspect ratio is set to FILL, H/V position returns
to 0, 0 and the H/V size is set to match the current output rate. Input sampling settings are
updated according to standard Auto‑Image operation. If the aspect ratio is set to Follow or
Fit, the H/V position and H/V size are set to maintain the native aspect ratio of the input in
respect to the current output resolution. All input sampling settings are updated according
to standard Auto‑Image operation. Image size and position are reset to default values after
auto imaging.
Press NEXT to select the input value and move to the next submenu.
NOTE: Aside from the standard Auto‑Image SIS command, there are unique
commands to Auto‑Image to fill the output and maintain input aspect ratio (see
Auto-Image and Memory
Preview HDMI Output
Use either front panel ADJUST knobs to select the refresh rate
of the Preview HDMI Output. It can be either 50 Hz or 60 Hz
(default). The resolution follows the archive output and cannot be
changed.
Press NEXT to select the value and move to the next submenu.
NOTE: When the selected archive resolution is under 720 lines (for example, if the
archive encoder is set as 848x480 or 512x288) the HDMI preview output is set to
1280x720, with the video content centered in the 720p window.
Auto Memory
AUTO MEMORY is enabled on all inputs by default. It should only
be disabled if the user desires to have a source applied to the
input treated as a new source regardless of whether the source
was detected previously.
When enabled and a new input frequency is detected, an
existing Auto Memory for the signal is first applied.
If no entry exists, it performs an automatic Auto‑Image on the new signal. This sets a size
and position for the image to fill the screen, with respect to the current aspect ratio setting.
The SMP 300 Series has 16 global memory locations, and stores unique entries for each
input format (for example, YUVi versus YUV-HD). Auto Memory saves H/V start, active
pixels, active lines, total pixels, phase, brightness, contrast, color, and tint settings.
The input lookup table identifies new analog inputs based on input type, total line count
of the input, and H/V frequency. Auto Memory locations associate with specific entries
in the input lookup table (not based solely on H/V frequency). For example, the RGBHV
1024x768 @ 60 Hz input lookup table entry can only have a single associated Auto Memory.
