NOTES:
• The audio test outputs pink noise on the embedded digital audio output
(Ch 1 and 2, 48 kHz, 16 bit).
•
All test patterns include a single pixel crop pattern line (except Blue mode).
Screen Saver and Timeout — Select the screen saver (see figure 11 ,
2
on the
previous page) to mute the video output when no active video is detected. The screen
saver can be set to a black (default) or a blue background for a specific (time-out)
duration, before the output sync is disabled. The time-out duration can be set to Never
(default), or to any duration from 1-500 seconds.
The screen saver option allows connected display devices to go into a low power standby
mode when the DSC 301 HD has no active input.
Input
x
: Auto-Image — Select this options (
3
) to turn the per-input Auto-Image mode
on or off. Auto-Image automatically attempts to size and position the image to Fill (or
Follow to follow the native aspect ratio of the input) every time a new input signal is
detected.
When enabled, Auto-Image mode is activated by switching physical inputs on the DSC
(such as IN2 to IN3), or by any interruption in input sync, even if the same input resolution
is detected (such as disconnecting and reconnecting the same input), or by a power
cycle. Issuing an Auto-Image with overscan enabled, runs an auto phase routine (YUV and
RGB only) and centers and sizes the input according to table values.
Input
x
: Aspect Ratio — Select this option (
4
) to set the per-input aspect ratio to
Fill (fills the entire output raster) or to Follow (follows the native aspect ratio of the
input).
When in Fill mode, if an Aspect Ratio adjustment for a single input rate is desired, the
correct size and center can be manually set up under Picture Controls (Image Size and
Position).
When in the Follow mode, each input rate is displayed with its native aspect ratio (4:3,
5:4, 15:9, 16:9, 16:10) with the correct letter box or pillar box settings visible under the
Image Size and Center Picture Controls.
Input
x
: Auto Memory — Select this option (
5
) to turn the per-input Auto Memory on or
off.
The DSC 301 HD has 32 auto memory locations per input, for RGB/YUV and HDMI
inputs. YUV and RGB signals on the same input have unique auto memories; for example
720p YUV and 720p RGB are stored with unique Auto Memory settings.
Auto memory locations store the same Input Config and Picture Control values as an
Input Preset, except for Input Type, Preset Name, Film Mode, or Audio Gain/Att.
Overscan — Select this option (
6
) to set the overscan mode ( 0% , 2.5% or 5.0% ) per
input type.
This zooms and crops SMPTE inputs to mask edge effects and ancillary data that are
common in broadcast signals.
NOTE:
Overscan is valid only on SMPTE input rates (NTSC, PAL, SECAM, 480p,
576p, 720p, 1080i, or 1080p, or 2k).
Auto Switch — Select this option (
7
) to turn the Auto Switch mode on or off, and to set
the priority. The Auto Switch setting allows for basic, unmanaged, input switching based
on the presence of active input signals. Auto Switch mode options are:
• Disabled (off)
• Setting priority to
High to low
(input 3 to input 1)
• Setting priority to
Low to
high (input 1 to input 3).
