3.2.3 Television aspect ratio
If you have a wide-screen television, set the TV Aspect Ratio
option to 16:9.
Otherwise, if you have a normal-screen television, set the TV
Aspect Ratio option to 4:3.
You cannot fully enjoy wide-screen programmes with your
normal-screen television as the above figures show. The left
figure shows a normal picture displayed in the normal screen.
To watch wide-screen programmes in the shape like the centre
figure, set the 16:9 Display Format option to Letter Box. Wide-
screen pictures then will be reduced to fit to the width of the
normal screen. Otherwise, to watch them in the shape like the
right figure, set it to Center extract. Wide-screen pictures then
will be cut out on the left and right sides equally to fit to the
width of the normal screen.
3.2.4 High definition television
The digital receiver supports various video resolutions from
576 to 1080. In general a resolution of 720 or more is considered
high definition. The higher the resolution is, the better quality
you can enjoy. However, if your television set does not sup-
port high definition, you cannot enjoy high definition quality
picture.
