Software Upgrade Through Rs232 - Sharp TU-R160HA Operation Manual

WIDE
TV sets are available with screens of the standard (4:3) format and widescreen (16:9) format. When
you first installed your receiver you specified the format of the connected TV (this can now be altered if
necessary; see Configuration)Digital terrestrial television broadcasts are also made in both standard
and widescreen formats. In particular, films and dramas tend to be broadcast in widescreen format to
closer emulate the cinema experience, but some programmes such as news bulletins are 4:3. To help
get the most from both TV set and programme when a widescreen film is watched on a standard TV,
or a standard broadcast is viewed on a widescreen set, the receiver includes the "WIDE" key.So long
as the receiver has been correctly set up for the TV set connected, a widescreen programme will
always be displayed correctly on a widescreen set, and a standard format programme will correctly fill
the screen of a standard format TV.
With a widescreen TV set displaying a standard format programme the "WIDE" key switches between
displaying the picture with black bars down the sides, and enlarging the picture so that it fills the whole
width of the screen but the top and bottom are cropped off.With a standard format TV displaying a
widescreen programme, the "WIDE" key switches between displaying the picture with black bars at the
top and bottom of the screen, and filling the whole height of the screen but cropping the sides off
according to instructions broadcast with the programme (called 'pan and scan').The effect of the
"WIDE" key on the picture display is cancelled by pressing "WIDE" again.
NOTE:
Sometimes the TV will automatically try and compensate for an incorrect screen format, in this
instance set the TV to the correct format whilst viewing the programme.
