FIG. 3 is a diagram illustrating an example, FIG. 3 is a diagram illustrating a specific example of the receiving apparatus, FIG. 4 is a block diagram illustrating a configuration of the receiving apparatus, and FIG. 5 is a flowchart illustrating the operation of the receiving apparatus. In FIG. 1, reference numeral 1 denotes a broadcasting device including a text multiplex broadcasting device for FM broadcasting.
Is a receiving device 2 for receiving and displaying character information, a transmitting device 3 for wirelessly transmitting information to the receiving device 2, and an input device 5 for inputting traffic information and the like to the transmitting device 3 through a telephone line 4 or the like. It has. To the receiving device 3, for example, data in the format shown in FIG. 2 is transmitted from the transmitting device 3 as character information. The data includes a header 8 for designating a source and characteristics of the information, It is composed of the text content 9 of the information. The receiving device 2 receives the received character information,
And a display 6 for displaying the position and the like of a predetermined facility. The display 6 displays the header 8 and the text 9 in three lines.
The display position, the display time, the display ratio between the character information and the map screen, and the like can be arbitrarily changed. The receiving apparatus 2 includes an operation function key 11, a direction key (cursor key) 12 for moving a cursor, and the like, and an operation confirmation key 13. [0015] The receiving device 2 is an antenna 16 and a tuner 18 which are character information receiving means for receiving a teletext signal transmitted from the transmitting device 3, and demodulates FM multiplexed data from the received signal. A demodulation unit 19 and a CPU (sound output control unit) 20 that controls reception by the tuner 18 and controls whether sound is output from the speaker 14 are provided. The CPU 20 is connected to a ROM 23 and a RAM 24 for storing control programs and the like, and inputs and outputs predetermined data. Also, an audio conversion unit 26, which is an audio conversion unit for converting the received character information into an audio signal, is connected. The audio signal is amplified by an amplifier 27 and output from a speaker (audio output unit) 14. It has become. The CPU 20 is connected via the I / F 31 to a navigation device 33 for performing route guidance from the current location to a predetermined location, and inputs the current position of the vehicle detected by the navigation device 33. It has become so. The navigation device 33 includes a ROM as position data storage means for storing position data of a predetermined facility such as a tollgate on a toll road, and the position data is input to the CPU 20 via the I / F 31. , The C
The sound output control function of the PU 20 stops the sound output from the speaker 14 at a predetermined facility, for example, near a tollgate on a toll road. Next, the operation of the receiving apparatus 2 of the present embodiment will be described with reference to FIGS. First, if there is no hold data scheduled to be read aloud by voice, and there is received data of character information when voice reading is instructed by the operation switches 11 to 13 (steps S1 to S3), the I / O The position data of the own vehicle detected by the navigation device 33 via F31 is read (step S4). If there is pending data in step S1, the process proceeds to step S4. If a predetermined switch operation is not detected in step S2, or if character data reception is not detected in step S3, The process moves to step S1. The input current position data is compared with the position data of the tollgate on the toll road stored in the ROM in the navigation device 33, and if the distance between the two is equal to or less than a predetermined value, the position is compared. Are determined to be close to each other, and character information data scheduled to be read aloud are stored as hold data (steps S6 and S7). On the other hand, if the distance between the two is equal to or more than the predetermined value, the reading of the reserved data or the received data in step S1 is performed (steps S6 and S8). Thus, according to the distance to the toll booth,
Since the text-to-speech reading of the text information receiving device 2 is stopped, when the driver is performing operations such as opening / closing a window and paying a toll at a toll booth, it is possible to stop the output of text-based broadcasting by voice. It is possible to prevent the voice output from being missed. In the above embodiment, the navigation device 33 is connected to the receiving device 2, but a GPS antenna and a GPS receiver may be connected. In this case, the position data of the predetermined facility is stored in a ROM or the like in the receiving device 2. In the above embodiment, the case where the predetermined facility is a tollgate on a toll road has been described. However, the present invention is not limited to this, and voices may be output so that the driver concentrates on driving operation or other operations. The sound output may be stopped when a place where the output is easily missed or a situation is detected. As described above, in the information receiving apparatus according to the present invention, the audio output of the information receiving apparatus is stopped in accordance with the traveling position or location such as approaching a predetermined facility, and thereafter, To
The driver can concentrate on driving operation and other operations because the driver can concentrate on driving operation and other operations.If it is easy to miss the voice output, the output of character information by voice can be stopped. There is an effect that the transmission can be reliably transmitted to the driver.
