Is sending the inaudible during a clock Carrier signal and thus the sending of a spoken traffic announcement recognized, the functional means are kept under current until the transmission of the inaudible carrier signal is ended. The meanwhile Spoken traffic announcement broadcast can be in a storage device of the car radio can be saved.
  • a disadvantage of this technical teaching is that spoken traffic reports only be sent at irregular intervals and the one Always up-to-date recording of spoken traffic reports necessary large number of switch-on processes - ideally in cycle times of only 1.5 seconds - only in very few cases for recording a spoken traffic announcement, but continues with one increased power consumption, which is particularly true in an environment in which there are limited power resources, such as in an automobile, can be disadvantageous.
  • TMC Traffic Message Channel
  • the TMC messages are a continuous digital data stream, which is included in the RDS.
  • the TMC transmission conveys traffic information, which are updated every five minutes. Since the TMC messages are transmitted in coded, language-independent form, can the information contained in the TMC messages according to their Decoding as writing, image or sound information (via the SDS, i.e. the "Speech Dialog System” also available as language) be put.
  • the object of the present invention is to save or update of digital data records, in particular TMC messages, in one To improve the receiving device.

  • the information unit of the first received data record with those of the further received data records is compared, it can be determined when a repetition the receipt of the first data record is present and in the case of a cyclical repetition of sending a complete set of data records the sending of a complete set of data sets is given. It however, it cannot be determined whether the individual records received "correct”, i.e. received with the originally sent content and therefore, for example, only data records with "correct” content can be saved.
  • TMC messages can be used to distinguish between individuals Information unit suitable for the combination of primary location and the value of the direction bit can be used.
  • a repetition A TMC message is present when two TMC messages with the same Primary location that was taken from the same location table and the same value of the direction bit was received. That combination from the primary location and the value of the direction bit of TMC messages can also be used to repeat the whole Set of currently sent TMC messages.
  • TMC multi-sequence messages consist of two to five so-called groups.
  • the first group of a TMC multi-sequence message contains standard information and is always sent first.
  • the further or the Additional groups contain and are additional optional information sent after the first group.
  • the TMC standard (more precisely at ALERT C) assumes that periodic message repetition from the immediate repetition of each group in the broadcast is accompanied.
  • the first group is repeated, then the second etc. If, for example, in a message A three Groups exist (A1, A2 and A3), then the immediate repetition of the message should (with three repetitions selected) A1 A1 A1 A2 A2 A2 A3 is A3 A3.

Overwriting of data records can be such Concern records whose validity period has expired or which have been replaced by modified newer messages. Overwriting the However, data records in the storage device can also be all stored there Data records relate, especially if, for example a complete new set in a buffer device Data records are available for storage in the storage device stands.
  • the method provides that only those data records received are saved, which are not identical to previously saved data records are.
  • This further training has the advantage that the storage process can be significantly shortened, especially if only a few or some of the records already saved by newly received records must be deleted or overwritten.
  • the receiving device shown schematically as an exemplary embodiment in FIG. 1 has an HF background tuner 10 for TMC messages, to which an antenna device 12 can be connected. Via the power supply device 14, 16, the RF background tuner 10 can be supplied with power via the controllable switch 16 via the clock generator T contained in the present example in the power supply device at a time interval of 15 minutes (t 15 ) selected here. In addition to the HF background tuner 10 for TMC data, further required components of the receiving device according to the invention can be supplied with current. The HF background tuner 10 forwards the received TMC messages to the excerpt / comparison and control device 18, shown here as a unit.
  • the extracting / comparing device 18 compares the information units suitable for identifying the TMC messages with those which are already stored in the storage device 20 for TMC messages. As soon as this comparison produces a specific, predeterminable result, the comparison device 18 outputs a comparison signal which is received by the control device 18, which is not shown explicitly here. The control device 18 then outputs at least one control signal for actuating the power supply device. In the selected example, this signal is an OFF signal. It is further provided in the present exemplary embodiment that the power supply device 14, 16 can or can delete the TMC messages stored in the memory device for TMC messages at intervals of 15 minutes (t 15 ).

  • the decoded data can then also by a optional or external output device 24 in the form of text, image and / or language are output.
  • TMC 2 shows a schematic illustration of the sequence of the TMC sent and receivable TMC messages 26, 28, 30, which are symbolic here are represented with the letters A to F.
  • TMC simple symbolic Display selected 6 messages.
  • a first TMC message "B" which is a message deals with a low priority, provided only a one-time reception a complete set of TMC messages currently being sent or is required, the reception of the TMC messages should be stopped as soon as the receipt of another TMC message "B" is determined.
  • TMC message "A" is a TMC message with low priority. Because within the complete Set of TMC messages no longer receives the TMC message "A" was, it can be assumed that this Record is about one that is no longer valid and therefore not more needs to be stored in the storage device. Should he be in the storage device due to a previous reception and Storage process, it can or should be from the Storage device to be deleted.
  • High priority TMC messages are transmitted within a complete set of TMC messages transmitted several times, as in right example of Fig. 2 represented schematically by the TMC messages "E" is. Will start after turning on 36 the power supply such a message is received when TMC messages are received the reception of the TMC messages continued until the repeated Receiving a TMC message with low priority - here schematically as TMC message "F" shown - is determined.
  • Prior art receiving devices which are suitable Receiving TMC messages does not become TMC messages in OFF mode receive. The same applies to that with certain receiving devices provided two-hour follow-up or when updating of the two-hour timer. During the two-hour run-on or the update of the two-hour timer is currently only TIM (traffic Information Message), i.e. spoken traffic announcements recorded.
  • TIM traffic Information Message
  • a receiving device cyclically Background tuner in low power mode every 15 minutes for one each determining time switched on.
  • the duration of the SCAN operation is determined by the Amount of TMC messages received determined.
  • Background tuners are switched back to OFF mode and only after be returned to SCAN mode after the past 15 minutes.
  • the TMC data thus indirectly control the switching off of the receiving device.
  • the recorded data is updated during SCAN operation. After completion of the update process - recognizable by the repetition the reception of TMC messages with low priority - is switched off again.
  • the waiting time of 15 minutes between two start-up processes is based on the minimum period of validity of TMC messages but can also be set to other periods.
