User Controls
The user interface for the HDP4 is a 4-switch DIP accessible through
a cut-out in the outside of the case (same side as the AC power
connector). Use the DIP switches to enable/disable and configure
scaling modes, and assign which AES audio channels are
disembedded.
The exact function of each DIP switch and what it controls is described on the following
pages.
Switch 1 SCALE—Turns Scaling On or Off
:
Switch 2 FULLSCRN—Selects Scaling Mode (when SW1 is ON)
:
Switch 3 AUDIO—Selects Two AES Channels for Disembedding
:
Switch 4 AUX—720p60 Output
ON OFF
Normal Operation Turns scaling off; the picture will output 1:1.
Note: only works when it is possible to display the
entire unscaled raster
For example, it is not possible to display a 1920 x
1080 input on a 1600 x 1200 monitor.
Use a 1920 x 1200 (WUXGA) monitor for
optimal performance. 1:1 scaling will then
be supported for all input formats.
OFF ON
Normal Operation (aspect ratio preserved) Scaler always fills screen as described in “Video
Scaling”
1/2 3/4
Selects AES Channels 1 and 2 for
disembedding from the SDI stream.
Selects AES Channels 3 and 4 for disembedding
from the SDI stream.
OFF ON
Normal Operation Forces the output to 720p60. Useful for
compatibility with most HDTVs.
