Abstract

<P>PROBLEM TO BE SOLVED: To reduce the problem that there are some services not actually receivable by a DAB receiver, when an operator pushes a preset key to select one of the services to be received. <P>SOLUTION: The DAB receiver previously stores preset information in a preset memory, including country IDs. When an operator depresses one of preset keys to select a service to receive, the receiver decides whether the service (program) corresponding to the depressed preset key is receivable (S43); then if the service is decided as being not receivable, it eliminates those services with the same country ID as a country ID attached to the service decided as being not receivable, and restructures the relation of preset numbers in the preset information to corresponding services (S45). <P>COPYRIGHT: (C)2004,JPO

x: Orthogonal Frequency Division Multiplexing), which has the characteristic that it is not easily affected by fading and multipath, and uses MPEG layer II for high-efficiency speech coding for speech coding, and transmits at 1.5 MHz. Bandwidth allows for many stereo and data broadcasts.

In DAB broadcasting, many programs are multiplexed and transmitted simultaneously. FIG. 9 is a diagram illustrating the DAB service structure. In FIG. 9, an ensemble is a unit of service transmitted by radio waves having the same carrier center frequency, and one ensemble has a plurality of services (services).
, And a plurality of service components (Service components) belong to the service. Thus, the DAB service structure is basically 3
It has a tree-like hierarchical structure of layers, in which an ensemble is arranged in an upper layer, a service is arranged in a middle layer, and a service component is arranged in a lower layer.

An ensemble whose ensemble label is DAB ENSEMBLE ONE has service labels of alpha 1 radio (ALPHA 1 RADIO), beta radio (BETA RADIO) and alpha 2 radio (AL).
It includes a plurality of (for example, 6) services (Service) such as PHA2 RADIO). The user will receive the selected service at the DAB receiver.

FIG. 10 is a block diagram showing an example of a conventional DAB receiver. Hereinafter, a conventional general DAB receiver will be described with reference to FIG. In this DAB system, it is assumed that OFDM (Orthogonal Frequency Division Multiplex) is adopted as a modulation method. In FIG.
An instruction to start reception, an instruction to start search, and an instruction for reception service in the DAB receiver 50 are given from the user to the MPU 31 via the operation panel 33. Specifically, the operation panel 33 includes, for example, six preset keys to which numbers 1 to 6 are sequentially assigned, each preset key is associated with a service to be received, and the corresponding information is preset information. It is stored in the preset memory 37b. In the following description, the preset key used for presetting may be referred to as a preset memory key, and the preset key used for recalling preset information may be referred to as a preset recall key.

When a DAB broadcast service to be received is selected via the preset key, the frequency information of the Ensemble to which the service belongs is sent from the MPU 31 to the PLL 1 of the front end 13 as a reception frequency setting signal.
Sent to 4. The reception frequency is stored as preset information in the preset memory 37 in association with the preset key, or the service ID (Sid) associated with the preset key is called and the Sid belongs to the service.
The carrier frequency of the Ensemble is read from the correspondence table stored in the memory of the MPU 31.

In the front end 13, a DAB carrier having a specific frequency is received via the antenna 11, processed, converted into a predetermined intermediate frequency signal (IF signal) capable of digital signal processing, and converted into an A / D converter. It is output to 15. In the A / D converter 15, the analog signal is converted into a digital information signal and supplied to the I / Q detector 16.
An OFDM demodulator 21 is composed of the I / Q detector 16, the FFT 17, and the DSP (digital arithmetic device) 18.

The I / Q detector 16 is divided into an I signal and a Q signal so that the OFDM signal can be processed in the subsequent stage.
It is supplied to FT17. Fast Fourier transform is performed by the FFT 17 and the DSP 18, and the channel decoder 23
Is supplied to. In the channel decoder 23, the order of signals is returned to the original order by de-interleaving.
g) and error code detection and correction are performed. The microprocessor (MPU) 31 corrects the error code and calculates the code error rate. When the code error rate exceeds a predetermined value, the decoding operation and the decoded signal obtained by the decoding are performed. A mute control signal for stopping transmission is given to the D / A converter 29.

In the channel decoder 23, only the selected service (program) is extracted based on the program designation signal, and the compressed audio information is MPEG decoder 27.
Is supplied to. In the MPEG decoder 27, the compressed audio information is decoded and decompressed, and the D / A
It is converted into analog information by the converter 29 and output as an analog audio signal.

As described above, the conventional DAB receiver 5 is used.
0 has a plurality of preset keys in the operation panel 33, and is any service among the plurality of services included in the received frequency, the received frequency corresponding to the broadcast service, the ID of the received signal itself. The heel is stored in advance for each preset key and stored in the preset memory 37b. When the operator presses one of the preset keys to specify the reception service, the reception service is switched to the service corresponding to the pressed preset key.
