Television Standard; Television Aspect Ratio - Topfield TF 6700 IRc User Manual

3.2.1 Television standard

3.2.2 Television aspect ratio

The digital receiver supports two television standards. One
is PAL standard, and the other is NTSC standard. PAL was
adopted in European countries while NTSC is adopted in USA,
Canada, Mexico and so forth.
If you have a PAL television, you have to set the TV Type
option to PAL. In that case, if you switch to a service of the
NTSC standard, the digital receiver will presents the pictures
converting 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. However,
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 pictures
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
