Definitions
- This code can have two or more digits according to as many programs as you want to put in the list of the programs which can be preset.
- the transmitters which are interested in this project will have, obviously, to agree on and draw up a CODES / PROGRAMS / PIECES list which, then, the common communications channels used by the press specialized in radio programs will circulate to the users.
- the block diagram in the picture 1 reports, in a very schematic way, those which are the basic elements of a radio receiver today: a tuner (1), a decoder of the RDS/PAD signal which, in turn, controls the tuner (1), a medium frequency amplifier, a discriminator for the audio signal revelation and, therefore, the low frequency preamplification and amplification phases which control the loudspeaker. There is, obviously, a luminous display which visualizes the current information.
- the tuner selector When you turn the apparatus on, the tuner selector is in a stand by position and allows the signal which is tuned by the tuner 1 to pass toward the medium frequency and the listening circuits (and it allows the indications toward the luminous display too), as it normally happens in actual radio receivers.
- the Tuner 2 starts its automatic search and begins to explore all the frequencies of the selected band.
- the system decodifies the RDS/PAD signal, separates the RDSP/PADP signal and presents it to a comparator which compares it with that coming from the preset programs/pieces selector. This comparation happens, obviously, for every frequency tuned during the automatic search of the Tuner 2. Only if the two signals coincide the comparator activates a MATCH signal which, in turn, sets the following functions :
- the transmitter stops transmitting the RDSP/PADP signal, so the comparator switches the MATCH signal off. Because of this:
- the counter has to have a number of bit equivalent to n
- the selector memory has to have a size equivalent to C x n bit, organized in C words, each one being n bit long.
- the system apart from allowing the normal use of a radio receiver set, that is the tuning in any transmitter of the selected band (manually or by means of the automatic search), also permits to tune in any broadcasting station which is transmitting a desired program/piece preset by means of a prefixed code, which is transmitted by the transmitter together with the RDS/PAD signal and which identifies the program/piece itself unequivocally.
- the tuning can be only automatic, as the broadcasting station which transmits the desired program/piece is a priori unknown.
- the system is not addressed only to the mobile receivers for which the RDS/PAD concept has been introduced, but it can be extended to the fixed installations too, so it allows to benefit by an automatic search concerning programs/pieces rather than frequencies.
- the PLS function can be activated even if the user is using other sound sources ( c. d. ,cassettes ) or if the apparatus is in a stand-by condition.
- the PLS function is based on the search of a numerical code in which you have previously keyd; you can use:
- the PTY function appears vague and not flexible, as it regards codes prefixed by the producer, which one can' t bring up to date at all; therefore thr PTY system doesn' t manage to involve the interest and the active participation of the transmitters, of the other media and of all the firms that mean to advertise their goods.
- PLS system By means of the PLS system, on the contrary, you can involve:
- the RDS system in this case is not useful as the car radio should be on for the duration of the whole journey so as to allow the automatic frequency passages according to the area; On the contrary by means of the PLS system, you have only to key in 7 and in few seconds the car radio tunes itself automatically in the frequency of " Radio x " concerning the city of Palermo.
- the PLS system can be defined as an " interactive system" thanks to which the transmitters and the users are be able to communicate among themselves more easily.
