Definitions
- the invention is based on a method for recording information transmitted over a radio frequency according to the preamble of the independent claim.
- the additional information such as a program identification (PI: Program Identification) for the unique Identification of a program content transmitted equally via one or more radio frequencies, traffic identification (TP: Traffic Program) identifying programs broadcasting traffic news, a list of alternative frequencies (AF: Alternative Frequencies) via which the same program is transmitted as via a currently received radio frequency and Information about other program chains (ON: Other Networks) enables, among other functions, an automatic tuning of the radio receiver to one Radio frequency.
- PI Program Identification
- TP Traffic Program
- AF Alternative Frequencies
- the additional information is divided into so-called groups, depending on the information to be transmitted of different types, with four blocks of 26 bits each, 16 bits of which contain the actual information and a further 10 bits of error detection and correction and the synchronization of the receiver with the RDS Serve signal, transmit.
- this information is used to still bring traffic information to the user when listening to a radio program via which no traffic information is transmitted.
- the devices mentioned evaluate the EON information in such a way that if traffic information marked by the TA identifier occurs within the program to which the EON information refers, the receiver for the duration of the traffic information from the currently received one is set to this radio frequency, and thus the reproduction of the traffic information is guaranteed. After the traffic information has ended, the receiver is tuned back to the original radio frequency which does not transmit any traffic information.
- DE 43 06 595 AI describes a radio receiver in the form of a car radio which has the possibility of automatically recording traffic information transmitted via a radio frequency and identified as such by an identifier.
- the radio receiver described also has a monitoring operating state in which, on the one hand, current traffic information can still be recorded even after it has been switched off, but at the same time an excessive load on the vehicle battery, which serves as an energy source for the radio receiver, is avoided.
- the means required for receiving and evaluating a radio frequency are supplied with energy in a clocked manner, but the components which have a particularly high energy consumption, such as, in particular, an LF output stage, are however completely switched off.
- the receiver is tuned to a predetermined radio frequency and the received radio frequency is monitored for the presence of an identifier identifying traffic information while the receiving and evaluating means are switched on. If an identifier is recognized, the receiving, evaluating and further recording means are permanently supplied with energy for the duration of the identifier and the information is recorded.
- the radio receiver described in DE 43 06 595 AI presupposes that a radio frequency before switching the device into the monitoring state on the receiving part is set via which traffic information is transmitted. If this is not the case, a state-of-the-art car radio, for example the devices mentioned by Blau Vietnamese-Werke GmbH, Hildesheim, initiates a TP-oriented station search, i.e. a search for radio frequencies that broadcast traffic information. In the case of several TP radio frequencies determined, the strongest reception is set as the reception frequency. The consequence of this is that, when the radio receiver is started up, traffic information is stored in the traffic information memory for the user of unknown transmitters, which under certain circumstances confuses the user. It is also possible that irrelevant traffic information from a remote radio station is saved for the current receiver location, which also adds to the confusion and also limits the generally scarce storage space at the expense of relevant traffic information.
- the method according to the invention for recording information transmitted via a radio frequency in which, in a monitoring state, the means required for receiving and evaluating a radio frequency are supplied with energy in a clocked manner, the receiving and evaluation means being set to a predetermined value during the on-period Broadcast frequency tuned and the received broadcast frequency is monitored for the presence of an identifier identifying information, wherein in the event of recognition of an information identifier, the receiving, evaluating and further recording means for the duration of the identifier are permanently supplied with energy and the information is recorded, and when the monitoring state is switched on, the predetermined radio frequency is determined as the frequency to which a radio frequency which has been set before switching on the monitoring state and does not transmit any information has the advantage that in the case of a through the user-selected radio frequency, via which no traffic information is transmitted, during the monitoring operating state, that is to say when the radio receiver is switched off, traffic information from the same transmitter as in the switched-on operating state is recorded in the traffic radio memory.
- the radio frequency set on the receiver before the monitoring state begins is reset. This saves the user from having to re-tune to the radio frequency that is actually desired.
- Figure 1 is a block diagram of the essential part of the invention of a radio receiver according to the invention for performing the method
- FIG. 2 is a flowchart of the inventive method. Description of the embodiments
- the control unit 1 connected to an operating unit has a clock generator 3 which can switch the controllable switch 12 in a clocked manner via the control unit.
- An output of the signal decoder 7 downstream of the IF stage 6 is connected to the controller 1 and a further output is connected to a memory 8 provided for recording and for querying traffic information. If the device switch 11 is closed, the operating voltage 13 reaches the LF stage 4 and the controller 1, which in turn closes the controllable switch 12 and thus also the HF stage 5, the IF stage 6 and the signal decoder 7 supplied with the operating voltage 13.
- the car radio is thus switched on and is in normal operation. If the car radio is to be brought into a monitoring state, in which a set radio frequency is monitored for the transmission of traffic information, but the program received via the set radio frequency is not reproduced, the device switch 1 must be opened, as a result of which in particular the LF level 4 is switched off becomes. By opening the switch 11, which is communicated to the controller 1 by a drop in the operating voltage at the output terminal of the switch 11 fed to it, the clock generator is triggered which now controls the controllable switch 12 in such a way that it is used to receive and monitor a radio frequency required functional means 5, 6, 7 clocked with operating voltage 14 are supplied.
- the controller 1 If, during the short switch-on phases of the clocked operating voltage 14, a signal identifying traffic information in the RDS signal is recognized by the signal decoder 7, the controller 1 holds the controllable switch 12 for the duration of the presence of the TA identifier in the switched-on state and controls it Memory 8 for recording the traffic information transmitted via the set radio frequency. If the signal decoder 7 determines that the TA identifier is no longer present at the end of the traffic information, the controller 1 reactivates the clock generator 3 for clocked switching of the controllable switch 12 on a corresponding signal from the signal decoder 7. The car radio is thus located back in the monitoring state, which is only by a renewed Traffic announcement or by closing the device switch 11 is interrupted or ended.
- the duration of the pauses between two T of switch-on of the operating voltage to less than 1.6 seconds maximum in the sense of energy saving but close to this limit, for example 1.5 seconds.
- the traffic announcement is read out in a manner known per se.
- control circuit 1 is connected to a second memory 15, in which a non-TP radio frequency set before opening the device switch 11 on the HF stage, and the TP radio frequency to which the non-TP frequency refers, can be stored ,
- DIN EN 50 067 provides so-called EON (Enhanced Other Networks) information as part of the radio data system, which is transmitted in groups of the "14A" and "14B" type.
- EON Enhanced Other Networks
- Traffic information before in the set program, that it does not transmit any traffic information itself, i.e. it is a non-TP radio frequency, but it does
- the controller 1 also has a data connection to the HF stage 5, via which the data of a frequency to be set can be fed to the tuning circuit of the HF stage 5.
- the second memory 15 can be supplied with frequency data from the EON data, which are evaluated by means of the signal decoder 7, namely the data of the TP radio frequency to which a set non-TP radio frequency refers, via the controller 1.
- the radio receiver described is the basis for the method described below with reference to FIG. 2.
- the program signal received via a radio frequency set by means of the tuning circuit at the HF stage 5 is reproduced via the LF stage and the loudspeakers 9 connected to it.
- the signal decoder 7 monitors the RDS signal of the set radio frequency for EON information, that is to say to references to other traffic information-transmitting, i.e. TP radio frequencies , as well as announcement identifiers (TA) that relate to such a different radio frequency.
- EON information that is to say to references to other traffic information-transmitting, i.e. TP radio frequencies , as well as announcement identifiers (TA) that relate to such a different radio frequency.
- the radio receiver is matched to the associated other, ie EON-TP radio frequency, for the duration of the TA identifier and the transmitted traffic information is reproduced. After the end of the traffic information, the radio receiver is tuned back to the originally set non-TP radio frequency.
- step 100 it is checked whether the radio receiver is tuned to a non-TP radio frequency (step 105). If no non-TP radio frequency, that is to say a TP radio frequency, is set, then this TP radio frequency is monitored in the manner described for the occurrence of traffic information and the
- a search is made in the second memory 15 for a TP radio frequency stored for the last set non-TP radio frequency (step 115). If no such TP radio frequency is found in the second memory 15 (step 120), that is to say the last non-TP radio frequency set did not refer to an associated TP radio frequency, then a Transmitter search for the strongest detectable TP frequency is initiated and the strongest reception TP radio frequency determined in the course of the search is set at the receiver (step 125), whereupon this is monitored for the occurrence of traffic information (step 110).
- step 120 If it is determined in step 120 that the data of a TP radio frequency are stored in the second memory 15, that is to say that the last non-TP radio frequency set had referred to a TP radio frequency, this is set at the receiver (step 130) and its Receiving quality checked (step 135). If it is determined that the TP radio frequency set cannot be received sufficiently, the alternative frequencies available for the TP radio frequency are checked with the same PI codes, i.e. the same program content, until an alternative worthy of reception is found (step 140) and in the case of a signal that is worth receiving Alternatively, this is set as a TP radio frequency on the receiver, whereupon the process continues with step 110.
- the alternative frequencies available for the TP radio frequency are checked with the same PI codes, i.e. the same program content, until an alternative worthy of reception is found (step 140) and in the case of a signal that is worth receiving Alternatively, this is set as a TP radio frequency on the receiver, whereupon the process continues with step 110.
- the alternative frequencies can be determined both on the basis of the AF data, that is to say lists of alternative frequencies transmitted by means of the radio data system, and also in the course of a station search by checking the program identifier (PI) of the receivable radio frequencies. If no alternative worthy of reception is found, the receiver determines another TP radio frequency worthy of reception as part of a station search (step 120) and monitors this for the occurrence of traffic information (step 110).
- PI program identifier
- Radio receiver by switching on the device switch 11.
- the second memory is then the last one set before the radio receiver was switched off Broadcast frequency read out and this set on the receiver (step 150).
- received radio frequencies can be monitored not only for traffic information, but generally for any type of marked information.
- information carriers other than the radio data signal can also be monitored for identifiers.
- a Duchsagekartung of the ARI (driver information system) system which is also transmitted via a radio frequency, can be monitored.
