4:3

the height of the screen. Wide screen
televisions have a ration of 16:9 while
conventional televisions have a ratio of 4:3.

Personal Zapping
A Philips trade marked feature which allows
any combination of favourite teletext pages
or TV channels to be stored in the coloured
Favourite Channels/Teletext keys. A total of
10 preferred channels/teletext pages of the
same subject or user can be stored in each
coloured key.
S-VHS Signals
These are 2 separate Y/C video signals from
the S-VHS and Hi-8 recording standards. The
luminanace signals Y (Black and white) and
chrominance signals C (colour) are recorded
separately on the tape. This provides better
picture quality than with standard video (VHS
and 8 mm) where the Y/C signals are
combined to provide only one video signal.
System
Television pictures are not broadcast in the
same way in all countries. There are different
standards: BG, DK, I, NTSC and SECAM. The
system setting (p. 6) is used to select these
different standards.
