Technical overview
4:3 TVs showing 16:9 programs
For a standard 4:3 TV showing a widescreen program, the program is too wide to fit on
the screen. The DIRECTV ® HD Receiver gives you 4 ways to fix the problem:
Letter box: If you choose the letter box format, the 16:9 image is shrunk
until the entire width of the program fits on your TV.
Since the aspect ratio of the program is maintained, the image
is no longer tall enough to fill your screen, so black/gray bars
are seen at the top and bottom of the screen.
Full: If you set your DIRECTV ®
images are stretched to fit the height of the screen, like in the
Letter box format. But instead of applying black/gray bars to
the top and bottom of the screen, the program image is stretched
vertically until it is tall enough to fill your screen.
Your entire TV screen is full, but the program images are a little
stretched to compensate for the program – to – screen mismatch.
Zoom 1: This format stretches the top and bottom edges of the image at
an equal ratio, keeping the 16:9 aspect ratio intact.
The left and right portions of the image will be cut.
Zoom 2: This format breaks the 16:9 aspect ratio and stretches the top
and bottom edges more than the left and right edges of the
image to view less distorted image than the one in Zoom1.
The top, bottom, left and right portions of the image will be
cut, but less than Zoom 1.

CHAPTER 1
Technical overview
16:9 TVs showing 4:3 programs
For a wide screen 16:9 TV showing a standard 4:3 TV program, the program is too tall
to fit on the screen. The DIRECTV ® HD Receiver gives you 5 ways to fix the problem:
Pillar box: If you choose the pillar box format, the 4:3 image is shrunk until
the entire height of the program fits on your TV. Since the aspect
ratio of the program is maintained, the image is no longer wide
enough to fill your screen, so black/gray bars are seen at the
left and right edges of the screen.
Full: If you set your DIRECTV ® HD Receiver to the Full setting, 4:3
images are stretched to fit the width of the screen, like in the
Pillar box format. But instead of applying black/gray bars to
the sides of the screen, the program image is stretched
horizontally until it is wide enough to fill your screen.
Your entire TV screen is full, but the program images are a little
stretched to compensate for the program – to – screen mismatch.
Zoom 1: This format stretches the left and right edges of the image at an
equal ratio, keeping the 4:3 aspect ratio intact.
The top and bottom portions of the image will be cut.
Zoom 2: This format breaks the 4:3 aspect ratio and stretches the left and
right edges more than the top and bottom edges of the image to
view less distorted image than the one in Zoom1.
The top, bottom, left and right portions of the image will be cut,
but less than Zoom 1.
Panorama: This format stretches the left and right edges of the image at a
certain ratio, keeping the center of the image intact.
The center of the screen will keep the equal ratio and the
expansion ratio increases toward the horizontal direction at
both sides.
