8-1-2 NAVIGATION MODES
To provide faster access by the user to certain pages within the Teletext service a method was included in the Teletext
specification for the broadcaster to link pages, so they could be accessed using a single key press. Due to the constraints of
how some equipment operated in the field one methods of linking or navigation of these pages were developed and are
known as FLOF .
FLOF (Full Level One Future)/FASTEXT
When user switches to Teletext at first, A given page will be selected. This page will most probably be the main index page
but it can be arranged that an advertising page comes up first. This will depend on how the broadcasting organization
wishes to use the new feature (X8/30).
At the bottom of this first page are four key words, or prompts, each word in a different colour. The colour of these prompts
will be matched by four colour buttoms on the remote control. For example:
WORLD NEWS
TV GUIDE
(Red)
(Green)
On pressing the green button (TV GUIDE) on the remote control unit, the next page will be the top TV guide page. This page
will have a row 24 set of prompts which when selected with the appropriate button will take the user quickly through the
pages associated with the initial choice of subjects. The next set of prompts could be:
BBC1
BBC2
(Red)
(Green)
Thus the use with a single key press can explore the sublect of interest. if the user chooses to go back, this is achieved by
pressing the index key.
