The
Preselection Function
for recording control loads the controller memory of the
recorder with the information about all programs required to be recorded. The viewer
chooses the required programs from television program guides, then enters the relevant
information into the recorder. PSF is always active when teletext is selected and is inde-
pendent from PDC.
The
Recording Control Function (RCF)
allows remote control, from a source of
transmission, of a recording made by a receiving equipment capable of preselecting the
program to be recorded. Such a function depends on the broadcaster sending a program
label in coded form together with the program.
In 54200 the RCF is active as soon as the user selects a PDC data set 1 to 9 in the
Teletext B system.
The contents of PDC data sets 1 to 4 can be changed by the user. Data sets 5 to 9 have
fixed data and are not programmable.
The instrument offers a special PDC service, the Multi Labelling. In this mode the con-
tents of PDC data sets 1 to 4 is transmitted in four parallel data channels. This is realized
by the Label Channel Identifier (LCI) part of the data packet 8/30 format 2.
