Technical overview
For example, if you have a standard resolution TV, you would set the Resolution button
to 480p/i.
Then programs received by the DIRECTV
converted to a resolution of 480p or 480i for display on your television.
This information can also be helpful when deciding how to connect your TV and VCR to
the DIRECTV ® HD Receiver. For example, if you have a High Definition TV capable of
displaying 1080i, and a standard VCR, you would want to use the COMPONENT, RGB
or DVI jacks (whichever your TV accepts) to connect the DIRECTV
You would then use the VIDEO OUT jack to connect your VCR.
This will provide each device with the highest quality video signal it is capable of using.
NOTE
• If you connect your TV to one of the composite video out jacks (VIDEO OUT, S-VIDEO OUT), and
you view a HD program with the DIRECTV
or 1080i, the picture will be slightly cropped at the top and bottom (the very top and bottom
edges of the image will not appear on the TV screen).
To avoid this problem, set the RESOLUTION button to the 480p/i position if your TV is connected
to one of the composite video outputs. Also, since the RGB, COMPONENT and DVI jacks do not
output the 480i video format, do not connect a standard definition TV capable of displaying only
480i video to the RGB, COMPONENT or DVI jacks. If you use the DVI jack, for the best access to
HD programming, connect the DVI/HDCP output to the corresponding DVI/HDCP input on your
HD Television (HDTV) or HDTV Monitor that supports High-bandwidth Digital Content
Protection (HDCP) technology.

Aspect ratio

In addition to resolution and interlacing, HDTV is also defined by the aspect ratio of its
broadcasts.
Aspect ratio means the shape of the screen as defined by the ratio of the screen's width
to its height. For analog TV and SDTV, the aspect ratio is 4 units wide by 3 units high
(usually written 4:3).
This is the familiar shape of conventional TVs — slightly wider than they are tall.
For HDTV broadcasts, the aspect ratio is 16:9 (nearly twice as wide as it is tall).
This is, not coincidentally, more like the shape of movies shown in theaters.
This makes HDTV an ideal format for broadcasting and viewing movies on a TV.
But what happens if you are watching a nearly square-shaped 4:3 broadcast on a
rectangular 16:9 TV, or vice-versa? The DIRECTV
a variety of screen formats to help you deal with those scenarios.

Screen formats

To deal with the mismatches that can occur between the shapes of TVs and the aspect
ratios of program broadcasts, the DIRECTV
format controls.
These controls allow you to pick a format to use for both 4:3 TVs showing 16:9 programs,
and for 16:9 TVs showing 4:3 programs.
Here is an explanation of the options. (Details for setting this preference are included in
Chapter 7.)
