3.2.2 Television aspect ratio

If you have a PAL television, you have to set the TV Type op-
tion to PAL. In that case, if you switch to a service of the NTSC
standard, the digital receiver will presents the pictures con-
verting into the PAL standard. However, it is inevitable to
lose a little picture quality. Likewise, the contrary case brings
about the same result.
The best thing is to watch PAL services with a PAL television
and to watch NTSC services with a NTSC television. How-
ever, a multi television set is able to process both of them. So
if you have a multi television set, you had better set the TV
Type option to Multi. Then the digital receiver will present pic-
tures without standard conversion.
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.
