Definitions

  • the invention relates to a receiver with a device for the selection of digitally coded messages Contain location information and other information and each as a new message and as a corresponding one Repeat messages with updated if necessary Content will be broadcast, with at least the new ones Messages are saved in the receiver and played back.
  • RDS radio data system
  • Specifications of the radio data system for FM radio are among others in the publication Tech. 3244-E, March 1984 of the European Runfunk Union (EBU).
  • Radio receivers with suitable RDS decoders can transmitted data in addition to audio reception with the Record and decode the same receiver.
  • the TMC messages are not only cyclical sent repeatedly while the content is still up to date also recipients after sending a new message switched on, still feed current messages to can and to increase transmission security.
  • the recipient therefore has the task of saving the message and every message received against this inventory check to see if it is a Repeat message or a new message. Just in the event of a new message, the content will be sent to the driver communicated.
  • a message is considered new if it either with none of the saved messages matches or one of the existing messages updated, for example the change in traffic jam length, but also the cancellation of a disturbance.
  • a message is considered new if it is regarding the location information, a direction information or the type of event from the saved messages differs.
  • the object of the present invention is a receiver to be specified for all those occurring in the company Situations the number of message outputs is not as is perceived as disturbing.
  • This object is achieved in that a new message saved after receipt and with a Timestamp and is provided with a variable that can take at least two values, one of which causes within a given time after the Repetition messages not received by timestamp saved and played back.
  • the recipient with the features of the invention has the Advantage that the output of repeat messages regardless of the infrastructure (service providers, Broadcasters etc.) and is therefore reliable. It will no information about the origin of the message is required, which makes message management easier and Storage space is saved compared to other solutions.
  • variable the value is set that the storage and Replay of a repeat message allowed and that at the receipt of a first repeat message Variable is set to the other value that when receiving further repeat messages, it is checked whether the specified time after setting the variable to the other Value has passed, and if applicable, that received another repeat message saved and played back and the variable is reset to the other value becomes.
  • This training ensures that the first A message can be updated very quickly, whereby the majority of the cases occurring in reality updates that are of interest to the user is covered.
  • variable be represented by a single bit is shown.
  • the variable be represented by a single bit is shown.
  • little Storage space is required, particularly clearly.
  • the respective one Area of application of the vehicle and other circumstances can as a disturbing number of reproduced Repeat messages can be of different sizes.
  • the predetermined time by the user can be preset.
  • the receiver shown in Fig. 1 has in itself known manner an antenna 1, a receiving part 2, a Stereo decoder 4, a NF amplifier 5 as well Power amplifiers 6, 7 and speakers 8, 9. That from the stereo multiplex signal delivered to the receiving part 2 in addition to the stereo decoder 4 fed to an RDS decoder 3, the output of which is connected to a microcomputer 13.
  • a microcomputer 13 serves to control the receiver for decoding, management, preparation for playback and selection of the TMC messages.
  • a keyboard 14 and a display device (display) 15 connected to the microcomputer 13 a keyboard 14 and a display device (display) 15 connected.
  • the output of the selected TMC messages can either be via the display 15 or as a voice output take place, for which purpose the microcomputer 13 via a Speech synthesizer 16 with an input 10 of the LF amplifier 5 is connected.
  • FIG. 2 shows a flowchart of the message update, which as a program in the microcomputer 13 (Fig. 1) upon receipt a message is processed.
  • a message TMC from one in the microcomputer 13 provided communication unit picked up and decoded.
  • this message appears with the current stock stored messages TMC1 to TMCn compared.
  • the Message is a new TMC message NTMC. If this is the case the message is stored at 26, with a time stamp TS, which corresponds to the current time H, and the Variables - hereinafter called the up-date lock US - Mistake.
  • the new message is output.
  • the program ends at 30.
  • the up-date lock US is active. Meets this, the time stamp TS is compared at 27 with the current time H. At 28 there is a branch depending on whether the one found at 27 Time difference H-TS is greater than the blocking time ST. If applicable, the message is updated at 29, the is the name of the message saved up to that point Repeat message overwritten and with a time stamp TS provided. Furthermore, the up-date lock US is activated and at 32 the message is output.
