Definitions

  • the invention relates to a receiver for digital radio (DAB).
  • DAB digital radio
  • DAB digital radio
  • a receiver for digital radio programs is known in which features of the received ensembles are stored in a table and both the reception time and the reception time of the respective ensemble are stored. This list is sorted according to actuality and when recording a new record the oldest record is deleted. By means of an operating element it is possible to search up and down within this list and to select an ensemble already received in the past, to which the receiver is set.
  • a DAB receiver is known in which a table is stored in which the content of a DAB ensemble is stored and is displayed to facilitate the selection of a new transmitter.
  • the frequency of the ensemble received is stored in a table and a relationship between the ensemble frequency and the ensemble identifier, which is contained in the fast-information-channel and the frequency is stored in the table.
  • a relationship between the ensemble identifier and the service identifier, which is also included in the fast-information channel is recognized and the service identifier is also stored in the table to establish a relationship between the service identifier and the service identifier. Displayed in the display, also inscribed in the table.
  • the object of the present invention is to provide an easier operation in that the search of a receivable ensemble takes less time. This object is achieved by a receiver having the features ⁇ of claim 1.
  • the invention allows further entries in the table, which go beyond the previously received ensembles, characterized in that the characteristics of other ensembles (OE) are also taken from the respectively received ensemble and entered into the table.
  • OE ensembles
  • the features entered in the table are accompanied by indicators which reflect the relevance.
  • this development can be designed such that when adding an ensemble in the memory of the table contents is re-sorted and / or that upon reaching the capacity of Table, a record with the lowest actuality is deleted.
  • the signals received via an antenna 1 are fed to a receiving part 2, the output signal of which is fed to a decoder 3.
  • a decoder 3 This in turn has an output which is connected via a low-frequency amplifier 4 with loudspeakers 5 (for the sake of simplicity, only one loudspeaker has been shown).
  • signals from the decoder 3 are fed to a controller 6, which controls the entire signal processing sequence in the receiver. This includes, among other things, the processing of inputs on the keyboard 7 and the display of information on a display 8.
  • the controller 6 is further connected to a memory 9, in which, inter alia, according to the invention, the list of ensembles is stored.
  • the controller 6 is connected to a control input of the Epfangsteils 2 to set this to the respectively desired ensemble.
  • the flowchart ( Fig. 1 ) returns the part of the program in the controller 6 ( Fig. 3 ), which is used to create or update the table.
  • an ensemble is selected by the user he wishes to receive.
  • the ensemble information EI is read out and formed at 14 a record containing the ensemble identifier (EId) and the frequency f of each ensemble.
  • identifiers of other ensembles can be read from the ensemble information at 13, so that then incurred at 14 a plurality of records.
  • Fig. 2 illustrated flowchart illustrates the choice of one of the stored ensembles, wherein in Fig. 2 only the associated frequencies are indicated.
  • an input follows that the ensemble following in the list should be set.
  • it is checked if the current frequency is fx ⁇ fm. If this is the case, it is increased by 1 at 24 x and the frequency f (x + 1) is set at 25. However, if the frequency fm has already been reached, then 26 is set to 0.
