Is surround sound available
on the Explorer 3100HD?

(sometimes referred to as a S/PDIF output or Dolby
Digital Output).

My Dolby digital receiver has an optical audio input. How can I connect the Explorer 3100HD to It?
The Explorer 3100HD contains a coaxial type (RCA
jack) digital audio output for connection to a surround
sound receiver. There are some aftermarket models
of adapters that convert the coaxial type of output
to an optical type for connection to those surround
sound receivers requiring that type of input.

How do you connect the Explorer 3100HD to an HDTV?
The following diagrams show the Explorer 3100HD
connected to an HDTV:
Normal Connection Method Recommended for 16:9 HDTVs
Connection Method Where Audio Is Split and Baseband
Video Out is Also Connected to HDTV - Recommended
for 4:3 HDTVs

My HDTV has RGB inputs. How do I connect the Explorer 3100HD to it?
The Explorer 3100HD contains YPbPr outputs. For HDTVs requiring RGB HV inputs, Scientific-Atlanta has an RGB adapter. This adapter converts the YPbPr video format to RGB with horizontal and vertical sync. The RGB adapter looks as follows:

My HDTV displays a vertically stretched or centered video image in the middle of the screen. How do I correct this?
Some 4:3 aspect ratio HDTVs display what appears
to be a vertically stretched or centered video image
within the display area when analog or standard-definition
channels are tuned. If this occurs, the image may
appear as follows:
If this does occur, check to see if the HDTV has
picture adjustments that will manipulate the image
so that it fills up the entire screen. If it does
not have picture adjustments, connect up the baseband
video out or S-Video from the Explorer 3100HD to
the HDTV (in addition to the YPbPr connection) and
switch the HDTV’s video input over to that
line where the baseband or S-Video is connected.
This will maximize the display area for analog channels
or standard-definition digital channels (Refer to
the second connection diagram On How To Connect
the Explorer 3100HD to an HDTV).
The reason this happens is that the Explorer 3100HD
is outputting to what it believes is a 16 x 9 aspect
ratio HDTV. The true definition of HDTV is a 1920
x 1080i or a 1080 x 720P resolution at a widescreen
16 x 9 aspect ratio. However, many TV manufacturers
have made HD ready 4 x 3 aspect ratio monitors.
Some HDTV’s, when connected via the YPbPr analog
component inputs, think that the signal coming in
is an HD 1080i signal. Therefore, the HDTV displays
the letterbox bars. Since the Explorer 3100HD is
displaying the side bars, the result may look like
one of the above images.

How do you get the Explorer 3100HD to display the channel information banner on the HD channel?
When the INFO key is pressed on the remote
control or from the Explorer 3100HD front panel,
the information banner appears for approximately
five seconds (on a SARA application site – those
sites running the Passport application may not see
an information banner). During this time, the HD
video is blanked out; however, audio is still present.
The Explorer 3100HD is not currently designed to
display the channel information banner on top of
an HD channel.

When will scaled HD video be available in the program guide? Can the Explorer 3100HD stretch or crop video to make it appear different on the HDTV?
The Explorer 3100HD does not show scaled video in
the IPG (on a SARA application site – the Passport
application may not allow the IPG to be brought up
on screen while tuned to an HD channel). When the
IPG is brought up while on an HD channel, the area
where the scaled video shows is black; however, the
audio is still present. The Explorer 3100HD hardware
does not support showing scaled HD video in the IPG.
Scientific-Atlanta is working on a future generation
HDTV settop that will have this capability. It is
targeted for Q4 2002.
The Explorer 3100HD is not capable of manipulating
the video image to stretch it, crop it, or zoom
it so as to allow the display area to be maximized.
