DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an FM multiplex receiver. More specifically, the present invention relates to a method for recognizing a code contained in FM multiplex data and storing information corresponding to the code in a message ROM. By outputting the synthesized speech using the speech data, the information corresponding to the code can be confirmed by sound.

[0002]

2. Description of the Related Art In FM multiplex broadcasting, a program different from a main program, for example, text information such as weather forecast, traffic information or news is multiplexed and transmitted to a current FM broadcast. There are two types of program: sequential type and recording type. The sequential type is displayed at the same time as it is received, whereas the recording type is stored in memory once and selected when you want to watch it. And characters are displayed on the display device.

FIG. 7 is a schematic block diagram of a conventional FM multiplex receiver. In FIG. 7, reference numeral 2 denotes an antenna, reference numeral 3 denotes a tuner, and reference numeral 4 denotes demodulation of multiplexed data from an FM detection output outputted from the tuner 3. An FM multiplex data processing unit for controlling a signal from a KEY unit 5 for selecting a program, a storage unit 6 for storing a program, and a LCD panel 7 based on character signal data. The display unit displays a program or a program menu.

In such an FM multiplex receiver, the program number and service identification number of the program stored in the storage unit 6 are shown in FIG.
Is displayed on the display unit 7 as a menu, and one of the menus is selected using the KEY unit 5, and then a program is displayed on the display unit 7.

[0005]

However, in such a conventional example, in order to confirm the information contained in the multiplexed data, it is necessary to display the information on the LCD panel of the display unit 7 and see it one by one. If the configuration has only a display,
In some cases, it is difficult to display all information on the LCD panel due to space limitations. In addition, when this configuration is used in a vehicle, it is difficult to carefully look at the LCD panel while driving. It is also dangerous.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object to provide an FM multiplex receiver capable of confirming information contained in multiplexed data without looking at a display unit. Aim.

[0007]

In order to achieve the above-mentioned object, the present invention is configured as follows.

That is, the present invention shows the information type of a program.
Information type code and when the program was offered
FM multiplex data including at least the information provision time code
In receivable FM multiplex receiver, recognizing the code recognition unit information type code and information provision time code included in the FM multiplex data, the information type code and information
Storage for storing audio data corresponding to the broadcast providing time code
Means, output sound and outputs the sound rather based on the audio data
Program means, and in the menu display state,
When specified, the information type code of the specified program
When the corresponding audio data is read and output as audio,
When a program is selected, information on the selected program
Read the audio data corresponding to the provided time code and
Output .

[0009]

According to the above arrangement, after the reception demodulation, the FM multiplex data is received.
Program based on the code included in the data
Information on the type and the program providing time can be confirmed by voice.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention. An FM multiplex receiver 1 according to this embodiment includes an antenna 2,
The point that the tuner 3, the FM multiplex data processing unit 4, the KEY unit 5, the storage unit 6, and the display unit 7 are provided is similar to the above-described conventional example.

This embodiment is configured as follows so that information corresponding to a code can be confirmed by voice.

That is, the FM multiplex receiver 1 of this embodiment
Recognizes a code included in a message ROM 9 storing a message corresponding to a code in the multiplexed data and a program included in a program demodulated by the FM multiplexed data processing unit 4 and stored in the storage unit 6, and A program genre identification section 8 as a control section for reading out corresponding audio data from the message ROM 9 and an audio output section 10 for reproducing the read audio data into audio and outputting the audio.

FIG. 2 shows an example of a program menu. This may be always displayed as long as the display unit 7 has a sufficient size, otherwise,
The program screen may be switched and displayed by operating the KEY unit 5.

In FIG. 1, a hatched portion represents a program to be currently selected, and the hatched portion is referred to as a cursor here for convenience. The cursor can be moved to another program by operating the KEY unit 5. When the cursor is on, pressing a selection execution key or the like provided on the KEY unit 5 selects the program on the cursor. It is displayed on the display unit 7.

The multiplexed data demodulated by the FM multiplexed data processing unit 4 is, as shown in FIG. 3, data corresponding to one program, a program management data header A for managing one program, a character Page data B such as figures and figures
And This program management data header A is shown in FIG.
The program management data header A includes an n-bit program information type code C. Therefore, the information type code C represents 2 ⁿ types of information types. You can do it.

The program genre identification unit 8 identifies the information type of the program from the information type code included in the program demodulated and stored in the storage unit 6, and outputs the audio data corresponding to the identified information type from the message ROM 9. It is to read.

An audio output unit 10 includes an audio synthesis unit 11 that converts digital audio data read from the message ROM 9 into an analog audio signal, an amplifier 12 that amplifies the audio signal, and a speaker that outputs audio. 13
It is composed of

In the FM multiplex receiver 1 having the above configuration, when the program menu is displayed on the LCD panel of the display unit 7, the cursor is moved by the KEY unit 5 and the cursor is positioned on the program to be selected. A voice corresponding to the information type of the program, for example, a voice such as “traffic information” is output from the voice output unit 10.

Therefore, it is possible to recognize whether or not a program to be selected is a target program by voice on a menu without actually selecting and displaying each program.

The page data B shown in FIG. 3 is composed of a page data header D and a group of data units as shown in FIG. This page data header D is shown in FIG.
As shown in FIG. 5, the page data header D includes a j-bit information provision time code E indicating when the page was provided with information. When this is used, when the program is displayed on the display unit 7, the information provision time code E is recognized by the recognition unit 8, and the audio data corresponding to the time data is read from the message ROM 9, Voice output is possible. In this case, when a program is selected or a page is changed, a sound such as "information provided at 20:15" is output.

[0022]

As described above, according to the present invention, based on a code included in received and demodulated FM multiplexed data, information corresponding to the code is stored in a message ROM. And the program providing time and the program providing time corresponding to the code
It is possible to check the information in the sound, which is very useful.
