Definitions

  • An object of the present invention is to provide a digital audio broadcast receiver which can select a program immediately and facilitate the selection operation of the program.
  • Another object of the present invention is to provide a digital audio broadcast receiver which can omit an extra work of beforehand registering ensembles in association with preset keys as in the case of a preset type receiver.
  • a receiver for digital audio broadcast in which plural programs are grouped, and the plural programs, the data representing the names of the groups and the data of the character sequences indicating broadcast stations are broadcasted through one transmission frequency band, characterized by comprising: a past record table provided to a controller with which when the digital audio broadcast is received, the data of the reception frequency thereof, the data of the character sequence thereof and the data corresponding to the name of the group thereof are assembled as a set and registered; a display device for displaying a list of the names of the groups on the basis of the data of the data corresponding to the names of the groups in the past record table; and the controller for controlling selection of the broadcast on the basis of the reception frequency data corresponding to a name which is selected from the list displayed on the display device.
  • a broadcast wave signal of DAB is received by an antenna 11, and the signal thus received is supplied to a tuner circuit 12 which is designed in a superheterodyne structure to convert the signal to an intermediate frequency signal. Thereafter, the intermediate frequency signal is supplied to an A/D converter circuit 13 to be subjected to A/D (Analog-to-Digital) conversion, thereby obtaining a digital signal.
  • A/D Analog-to-Digital
  • the digital signal thus obtained is supplied to an orthogonal demodulation circuit 14 to be decoded into data of an in-phase component (real-axis component) and an orthogonal component (imaginary-axis component), and these data are subjected to complex Fourier Transform in an FFT circuit 15 to output frequency components every symbol.
  • the output of the FFT circuit 15 is supplied to a viterbi decoder circuit 16 to be subjected to deinterleave and error correction, and also digital audio data of a desired program (service component) are selected.
  • the data thus selected are supplied to an audio decoder circuit 17 to be subjected to decode processing such as MPEG data expansion, and the digital audio data of the desired program are picked up from the decoder circuit 17. Thereafter, the digital audio data thus picked up are supplied to a D/A converter circuit 18 to be D/A-converted to analog audio signals L, R, and then the signals L, Rare supplied to amplifiers 19L, 19R to be amplified, and then supplied to speakers 21L, 21R to reproduce the original broadcast signal.
  • decode processing such as MPEG data expansion
  • a microcomputer 31 is provided as a system controller. Since the tuner circuit 12 is generally designed so that an ensemble (reception frequency) is selected by PLL, the data of a frequency division ratio N of a variable frequency dividing circuit in the PLL are supplied as frequency data for ensemble selection from the microcomputer 31 to the tuner circuit 12.
  • Data necessary to identify or specify a program that is, the data of an ensemble label (representing the name of an ensemble), a service label (representing the name of a service), etc. are picked up from the viterbi decoder circuit 16, and then these data are supplied to the microcomputer 31.
  • the processing goes to a step 122 to supply the ensemble labels of the table HTBL to LCD 35, and the ensemble labels (names) of every eight stations are displayed in forward order on LCD 35 as shown in Fig. 5(A), for example.
  • a first ensemble label is displayed in such a manner as to be surrounded by a rectangular frame, which means a cursor 35C.
  • the names of the ensembles (ensemble labels) which were previously received are displayed in a list style in name order (e.g., alphabetical order) on LCD 35.
  • step 123 the user is allowed to select any one of the ensembles whose names are displayed on LCD 35. That is, upon pushing a down cursor key out of the keys 34 in the display state shown in Fig. 5(A), the cursor 35C is shifted to a second ensemble label (name) as shown in Fig. 5(B). Upon further pushing the down cursor key, the cursor 35C is shifted to a third ensemble label as shown in Fig. 5(C).
  • the processing goes to a step 125.
  • the service ID paired with the ensemble label selected in the step 123 is picked up, and the selection signal SSV indicating the service ID is supplied to the viterbi decoder circuit 16 to select the corresponding service. For example, if "Ensemble B" is selected in the step 123, the service ID paired with the "Ensemble B” is equal to a value ID7 and thus the selection signal SSV indicating the service ID (ID7) is supplied to the viterbi decoder circuit 16 to select the service of the service ID (ID7).
  • the list key is pushed under the key input standby state in the step 103, the list of the ensembles which were previously received is displayed on LCD 35.
  • the user can listen to the program of the ensemble.
  • the key corresponding to a desired selection method out of the keys 34 is pushed when the processing waits for the key input.
  • the processing goes from the step 103 to a step 111.
  • the processing goes from the step 111 to a step 112, and it is judged in the step 112 whether the pushed key is a key relevant to the program selection.
  • the key is the relevant key, and thus the processing goes from the step 112 to a step 131.
  • the program selection is carried out by the same method as a general DAB receiver in accordance with the selection method of the program for which the key input is carried out in the step 103. For example, a scan operation is carried out or a different program (service component) of the same ensemble is selected. Thereafter, the processing goes to a step 132 and the table HTBL is renewed in the step 132.
  • the reception time thereof is renewed on the basis of the current time indicated by the time counting circuit 33. Further, if any set of the frequency division ratio N of the variable frequency dividing circuit in PLL of the tuner circuit 12 under reception operation, the service ID and the serial number of the service component does not exist in the data of the table HTBL, it is paired with the current time indicated by the time counting circuit 33 and newly registered in the table HTBL. At this time, if the empty capacity of the memory 32 is lack, a set of data having the oldest reception time is deleted.
  • the program corresponding to the key operation is selected, and the user can listen to the program.
  • the processing of the microcomputer 31 Upon pushing the key corresponding to desired processing out of the keys 34 when the key input standby state is set in the step 103, the processing of the microcomputer 31 goes from the step 103 through the step 111 and the step 112 to a step 141 to execute target processing, for example, processing of controlling the signal level of the amplifiers 19L, 19R to alter the volume, and then the processing returns to the step 103 to wait for the key input again.
  • target processing for example, processing of controlling the signal level of the amplifiers 19L, 19R to alter the volume
  • a list of ensembles which were previously received is displayed on LCD 35, and any ensemble is selected from the ensembles thus displayed, whereby the user can listen to the program. Accordingly, the ensemble can be just immediately selected, and the selection of the ensemble is easy. Further, it is unnecessary that ensembles are registered in advance as in the case of a preset type receiver, and thus no extra time is needed.
  • the data of the table HTBL are sorted and displayed in order of ensemble labels in the steps 121, 122.
  • the data may be sorted in order of N-value or reception time so as to be displayed in increasing order of frequency or in order of reception time from newest to oldest.
  • a selection frequency for each ensemble may be counted to sort and display the ensembles in decreasing order of the count result.
  • the data of the table HTBL are sorted in the step 121.
  • the data may be sorted when the data of the table HTBL are altered.
  • the user may be allowed to beforehand select items when the data of the table HTBL are sorted.
  • the frequency information of other ensembles broadcasted is simultaneously transmitted, so that the frequency information or the corresponding ensemble labels can be also displayed in the step 122.
  • the ensembles indicated by the frequency information may not be actually received because of a geographical condition or reception antenna state. Therefore, the display of the ensembles is carried out with varying the display mode from the display based on the data of the table HTBL, for example by attaching an identification mark to the ensembles, changing the display color, or grouping and displaying these ensemble labels so as to discriminate these ensemble labels from the group of the ensemble labels of the table HTBL.
  • the processing may be executed in accordance with a user's instruction or automatically so as to gain the frequency information of all the broadcasts receivable at a current reception place and contain the frequency information or the ensemble labels thereof in the display of the step 122.
  • the display mode for the ensemble labels of ensembles which are not actually received may be made different from that of the display based on the data of the table HTBL.
  • the display mode of the ensemble label may be set to that of the display based on the data of the table HTBL.
  • a service is provided with an identifier which is called as a program type and indicates a music genre, and thus the display may be grouped on the basis of the identifier. Further, when the language is different every service, an identifier indicating the language is added every service, and thus the display can be grouped every language.
  • the program can be immediately selected, and the selection is easily performed. Further, it is unnecessary that the ensembles are beforehand registered as in the case of the preset type receiver, and thus no extra time is needed.
