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.
