Digital Teletext - Hitachi 22LD4500 Instructions For Use Manual

DIGITAL TELETEXT

Many digital terrestrial television channels not only broadcast pictures and sound
for programmes but also pages of information on the programmes, the weather,
news and many other topics.
Some channels are entirely given over to digital teletext and carry no normal TV
programme at all. These dedicated digital teletext channels will not give a quarter-
screen image in the EPG or the Channel List screen. When such a channel is se-
lected, after a brief pause, they will usually display the opening page of information
automatically.
Other channels have digital teletext pages broadcast alongside the television pro-
gramme and often include a reduced-size broadcast picture within digital teletext
pages. These usually require the teletext keys to be pressed to activate the digital
teletext pages.
In both cases, moving through the
different pages of information is ac-
complished in a variety of ways,
dependent on the individual broad-
casters, but including use of the
"
LECT" keys to select items from
on-screen menus, and the co-
loured keys to jump directly to par-
ticular pages.
You can exit any digital teletext
channel by changing channel in any
of the normal ways. You can leave
the digital teletext function of a com-
bined digital teletext/programme
channel, to return to normal televi-
sion viewing of that channel, by
pressing the "
22
", " ", " ", " " and "SE-
" key. .

Hint
Calling for the information banner or any
menu on-screen stops the TV from dis-
playing the digital teletext pages and
they are temporarily replaced by a blank
picture while the banner or menu is dis-
played. Digital teletext cannot be ac-
cessed when the Subtitles are enabled
