  • the invention relates to a radio receiver, in particular one suitable for receiving radio data Radio receiver for a motor vehicle, with a Receiving part for setting, receiving and Demodulation of a broadcast frequency to be received, a decoder for next to a radio program via a received radio frequency transmitted radio data, a display unit for displaying as part of the radio data transferred program name and a memory with Storage spaces for storing radio programs characteristic program identifiers, and a method for Display a program name one over a currently one suitable for receiving radio data Radio receiver, in particular an RDS radio receiver for operation in a motor vehicle Broadcasting frequency transmitted radio program the genre of independent patent claims.
  • Radio Data System RDS for VHF / FM sound broadcasting "of the European Broadcasting Union from March 1984 are used to transmit additional information in the form of digital data, such as program identifiers (PI), via radio broadcasting frequencies of radio broadcasters, in addition to the actual broadcasting programs
  • PI program identifiers
  • Receiving this data suitable radio receiver can perform a variety of operations, in particular those necessary for undisturbed reception, independently and without user intervention, so that, for example, the driver of a motor vehicle in which the radio receiver is installed does not have to make any manual entries on the RDS car radio and so that his attention can be fully focused on road traffic.
  • RDS radio data system
  • NDR2 Program Service Name PS
  • SR1 Saarland's first radio program Broadcasting
  • Radio receivers suitable for receiving radio data are known in the form of RDS car radios, which have a receiving part for setting, receiving and demodulating a radio transmission frequency to be received, a decoder for radio transmitted alongside a radio program via a received radio transmission frequency -Data and a display unit for displaying the program name (PS) transmitted as part of the radio data, and which contain a program name (PS) transmitted in coded form by means of the radio data system of a currently received radio program in the form of plain text on your display Show.
  • PS program name
  • An inventive radio receiver and that Method according to the invention with the features of independent patent claims have the advantage that even in the event of misuse of the PS information for other information such as Scrolling texts or advertisements for display on the car radio display as the program name of the radio program currently being heard are not suitable, the actual or a user-definable program name of the current on Broadcast receiver set radio program on the Display unit of the radio receiver is shown.
  • Radio receiver with a reset button Equip input unit, whereby by means of Reset button a stored in the radio receiver user-defined program name can be deleted, so that instead of the user-defined program name using the PS information of the radio data signal transmitted Information on the display unit of the radio receiver can be represented.
  • Figure 1 shows schematically the structure of the invention Radio receiver using the example of an RDS car radio for Operation in a motor vehicle.

  • the input unit 35 comprises the number keys required to operate the radio receiver or to select stored programs, whereby letters can be generated instead of the numbers by double assignment of the number keys with repeated successive operation of one and the same key, such as this, for example, from the car radio described in the Blau Vietnamese brochure mentioned at the beginning with an integrated mobile radio telephone with the type designation Amsterdam TCM 127 "is known.
  • the controller 15 of the radio receiver 10 described the task comes about, using the controls of the Input unit 35 generates user-defined program names in the other memory locations 72, 74, 76, 78 of the PS list 70 write the memory 50.
  • the falls Control also the task of enrolling one user-defined program name PS 'in the memory 50 the other storage location 72, 74, 76, 78 to select the broadcast program currently received or the currently received radio program identifying identifier.
  • the controller 15 also has the task of checking whether a user-defined program name PS 'is stored in the PS list 70 of the memory 50 for a radio program currently being received, or the program identifier PI associated with the received radio program. If this is the case, this stored user-defined program name PS displayed primarily on the display unit 40 of the radio receiver before a program name PS transmitted by means of the radio data signal via the radio transmission frequency currently set on the radio receiver frequency.
  • FIG. 2 schematically shows a section of an according to the radio data signal 100 transmitted to the radio data system, that according to the RDS specification mentioned in Groups 105 is divided into 106 bits each. Every group in turn comprises four blocks 110, 120, 130 and 140 of 26 bits each, in the RDS specification as blocks A, B, C, D, each block an information part 112, 122, 132, 142 and a so-called Check word with overlaid offset word 114, 124, 134, 144, includes.
  • the actual, using the radio data signal too transmitted information is in the Information words 112, 122, 132, 142 of blocks A, B, C, D (corresponding to reference numerals 110, 120, 130, 140) included, while the 10-bit test and Offset words 114, 124, 134, 144 of each block of the Error detection and / or correction (test word), as well as the Synchronization (offset word) of an RDS radio receiver serve on the radio data signal.
  • the group type is an example of this 0A, in its first block 110 a program identifier (Program Identifier PI) is broadcast, which indicates which program on the one just received Broadcasting frequency is broadcast.

  • RDS radio receivers With commercially available RDS radio receivers, the for example from the company's prospectus Blau Vietnamese are known, are within the group types 0A and 0B transmitted program name information PS of the transmit the currently set broadcast frequency Broadcasting program using the decoder 30 from the radio data signal isolated and on the display unit 40 des Radio receiver 10 shown.
  • the program name includes up to eight numeric and / or alphanumeric characters and is static, that means unchangeable in time. An exception this immutability over time is then permissible if, for example, several radio programs share common broadcasting frequency so that for example, a first program in the morning and a second program in the afternoon on the same frequency be sent. In this case it is permissible that the Program name when changing the program from a first to a second program name is switched.
  • FIG. 3 shows a flow chart for an inventive Method in the present embodiment in the form of software in the controller 15 of the invention Broadcast receiver is implemented.

  • the program identifier i.e. the PI code, which is assigned via the currently set transmission frequency is transmitted from which read from the RDS decoder 30 RDS data stream.
  • step 225 the controller 15 checks in Step 230, whether on that memory location 72, 74, 76, 78 the PS list 70, the storage location 62, 64, 66, 68, on which the over the currently set broadcast frequency received program identifier PI is stored, assigned a user-defined program name PS 'is stored is. If so, which is checked in step 235, so in step 240 the one that is currently set Broadcasting frequency transmitted program identifier assigned user-defined stored in memory 50 Program name PS 'read from the memory and from the Control 15 to the display unit 40 to display the Program name forwarded. The process finally ends with step 250.
