Definitions

  • This invention relates to a receiver for digital audio broadcasting.
  • DAB Digital Audio Broadcasting
  • Eureka 147 standards is employed as digital audio broadcasting.
  • the DAB adopts:
  • a broadcast of programs has a hierarchical structure such as shown, for example, in FIG. 13.
  • the DAB uses the transmission bandwidth of 1.5 MHz for one channel as mentioned above, and the transmission channel is called "ensemble" as seen in FIG. 13.
  • Each ensemble is selected by tuning with the central frequency of the ensemble.
  • the ensemble is divided into groups called services.
  • the ensemble A shown in FIG. 13 is divided into four services.
  • Each service is divided into several "service components".
  • Each service component is a digital audio signal or digital data which forms one program.
  • a service corresponds to one of ordinary broadcasting stations and is used in such a manner that, for example, a soccer match (program 1A) played in a first location is broadcast in the first service component of the service 1 of the ensemble A and another soccer match (program 1B) played in a second location is broadcast in the second service component.
  • a service is used in such a manner that a news program is broadcast in English in the first service component and another news program is broadcast in French in the second service component.
  • each of the ensembles and the services is given an identification code called “ensemble ID” or “service ID” for identifying the same.
  • Each of the ensembles and the services is also given an "ensemble label” or “service label” for indicating the name of the same.
  • each service component is given a sub channel ID for identifying a sub channel which is a minimum information unit which can be selected by the receiver side.
  • the service component is generally not given a label and is called like "primary service component", “secondary service component 1", “secondary service component 2" ... .
  • an ensemble is selected first, and then one of a plurality of services included in the ensemble is selected, whereafter an object service component (program) is selected from within the selected service.
  • a presetting function is prepared in some FM receivers and AM receivers. If the presetting function is executed, then frequencies of broadcasts of broadcasting stations which can be received are registered into a memory for channel selection so that any of the registered broadcasting stations can thereafter be selected by simple key operations.
  • a digital audio receiver for receiving a digital broadcast which includes a plurality of programs classified in hierarchies and is broadcast with a single transmission band, comprising a display unit for displaying information regarding a program being received and displaying items of one of levels of the hierarchy in the form of a list, and control means to which first and second operation keys, a display mode key and a decision key are connected, the control means controlling so that, when the display mode key is operated to establish a first display mode, information regarding the program being received is displayed on the display unit; when the display mode key is operated to establish a second display mode, the items in the hierarchy are displayed in the form of a list on the display unit; when the first operation key is operated, the level of the hierarchy to be displayed on the display unit is changed; when the second operation key is operated, an item of the level of hierarchy displayed on the display unit is selected; and when the decision key is operated for a result of the selection, a program corresponding to the selected item is selected.
  • a level of the hierarchy is selected by the first operation key, and an item in the selected level of the hierarchy is selected by the second operation key. Then, a program is selected in accordance with a result of the selection.
  • a level of the hierarchy to be selected can be freely moved to an upper level or a lower level.
  • an object item can be selected using the second operation key. In this manner, the key operations are standardized. Accordingly, upon the selection of an object program, this can be selected simply.
  • FIG. 1 there is shown a receiver for digital audio broadcasting to which the present invention is applied. Broadcasting signals of the DAB are received by an antenna 11, and the received signals are supplied to a tuner circuit 12.
  • the tuner circuit 12 includes a PLL (Phase Locked Loop) not shown and is formed in a superheterodyne system such that a reception frequency may be changed by varying the dividing ratio N of a variable frequency dividing circuit not shown of the PLL.
  • a baseband signal of the DAB is demodulated by and outputted from the tuner circuit 12 and is then supplied to an A/D converter 13, by which it is converted into a digital signal by A/D conversion.
  • PLL Phase Locked Loop
  • the digital signal is supplied to an orthogonal modulation circuit 14, by which data of an in-phase component (real axis component) and an orthogonal component (imaginary axis component) are demodulated.
  • An FFT circuit 15 complex Fourier transforms the data to reproduce multi-carriers, D-QPSK demodulates the data for the individual carriers and frequency deinterleaves the data.
  • An output of the FFT circuit 15 is supplied to a Viterbi decoder circuit 16, by which deinterleaving and error correction are performed for the received data and digital audio data of an object service component (program) is selected.
  • the selected data is supplied to an audio decoder circuit 17, by which decoding processing such as MPEG data decompression is performed for the data, and digital audio data of the object service component is outputted from the audio decoder circuit 17.
  • the thus outputted digital audio data is supplied to a D/A converter circuit 18, by which it is converted into analog audio signals L and R by D/A conversion.
  • the signals L and R are supplied to speakers 21L and 21R through amplifiers 19L and 19R, respectively.
  • a microcomputer 31 for controlling the system is provided as control means, and as frequency data to be used to select an ensemble (reception frequency), data of a frequency dividing ratio N of the variable frequency dividing circuit of the PLL is supplied from the microcomputer 31 to the tuner circuit 12.

  • the data for program selection stored in the memory 311 are data necessary to select, for each of programs, the program and include an ensemble ID, a service ID, a sub channel ID, an ensemble label, a service label, a dividing ratio N and so forth.
  • Such program selection data are stored into the memory 311 when a key operation for presetting is performed or when a program is selected and decided by manual operation.
  • an LCD (Liquid Crystal Display) unit 32 is connected as a display unit to the microcomputer 31.
  • the LCD unit 32 can display characters and so forth in a necessary size in the form of combinations of dots arranged in a matrix thereon.
