In FIG. 1, an FM broadcasting station 1 multiplexes an audio program 4 and a character program 5 by a multiplexing transmitter 3. Reference numeral 2 is a receiving device for receiving and displaying teletext.

Specifically, the receiving device 2 has a receiver for teletext (eg, visible radio) 2a shown in FIG. 2 and a navigation device 2b shown in FIG. The display device 6a as a display means for displaying character information of the visible radio 2a includes display units 7a to 7c of three lines, and the display device 6b of the navigation device 2b has a display unit 7a of eight lines.
~ 7h, and each of the display units 7a ~ 7h has 15
Characters are displayed.

In the radio 2a and the navigation device 2b which are visible, the operation function keys (preset keys) F1 to F7 (representative reference numeral 11), the direction key (cursor key) 12 for moving the cursor, etc., and the confirmation of the operation. And keys 13 and 13 respectively.

The receiving device 2 includes an antenna 16 and a tuner (reception means) 18 for receiving a teletext signal transmitted from the transmitting device 3, and a demodulator for demodulating FM multiplex data from the received signal. 19 and.

The CPU 20 of the visible radio 2a and the navigation device 2b has a function as a display control means for obtaining and displaying the changing tendency of the traffic congestion situation based on the traffic congestion information received and accumulated.

An I / F 21 is connected to the CPU 20, and a signal indicating a vehicle state (shift position, steering angle, half door, etc.) detected by a sensor (not shown) via the I / F 21. Alternatively, a signal indicating the traveling position is input.

Furthermore, the CPU 20 has an IC card 22, a ROM 23, which is a storage device which functions as a storage means for accumulating traffic congestion information in the received character information.
The RAM 24 is connected to input and output predetermined data, and the calendar timer 25 is connected to input date and time information.

A converter 26 for converting the received character information into voice data is connected to the CPU 20, and the converted voice data is output from a speaker 28 via an amplifier 27. Has become.

Data of the format shown in FIG. 5, for example, is input to the transmitter 3 from the input device 5 as character information. The above data is the source of the information,
It is composed of a header 8 having a control code or the like as an identifier for designating the characteristic of the information, and the content 9 of the information.

Next, the operation of the receiver 2 will be described with reference to FIG. First, a menu of teletext programs currently being broadcast is displayed by tuning a predetermined frequency, and when a traffic information program is selected from the menu item, the program is displayed (steps S1 and S2). At this time, when the traffic congestion prediction display is not instructed by the key operation or the like, and when the received traffic information program includes traffic congestion information, the content of the traffic congestion information is stored in the RAM 24 or the like. (Steps S3 to S5).

Here, in the RAM 24 or the like, for example, as shown in FIG. 7, the route name in the received traffic jam information,
Location information such as point names, date and time information such as months, days of the week, and holidays,
Also, the traffic congestion tendency information such as the total traffic congestion distance at the specific time and the number of receptions at the specific time is stored.

On the other hand, if the prediction display of the traffic jam condition is instructed in step S3, the route name, the spot name, etc. are displayed (step S6), and the route name etc. are selected (step 7). ), Date information such as the current month, day of the week, and holidays is read from the calendar timer 25 (step S8).

Then, from the contents of the traffic jam information stored in the RAM 24 or the like, the traffic jam tendency in a specific month, day of the week, etc. at a specific place is obtained as, for example, an average value of the traffic jam distance over time, and the traffic jam is calculated. The tendency is displayed (step S9), and the process proceeds to step S4.

Here, the prediction display of the congestion tendency is performed as shown in FIGS. 8 and 9, for example. That is, for example, if the Tennozan tunnel of the Meishin Expressway is selected as the route name and the spot name on Monday in March, the accumulated values shown in FIG. 8 at the same route and at the same spot on Monday in March are read from the RAM 24. The traffic congestion tendency shown in FIG. 9 is displayed.
When the display 6a for displaying three lines is used, the display data 30 is displayed by scrolling left and right. Further, when the navigation device 2b is used as a receiving device, map information regarding the predetermined place may be displayed together with the traffic jam condition.

As described above, since the tendency of the change in the traffic congestion status at the corresponding place on the corresponding month and day of the week is obtained and displayed from the accumulated value of the received and stored traffic congestion information, for example, in FIG. The peak of traffic congestion is around 8:00 am, and after that, it is possible to predict changes in traffic congestion, such as to resolve the traffic congestion. For example, if it passes at noon, it will not be possible to meet the traffic congestion. Further, by displaying the traffic congestion tendency on another route, it is possible to select a road with a low traffic volume.

[0022]

As described above, in the character information receiving apparatus according to the present invention, the traffic congestion information of the character broadcasting data is accumulated, and the change tendency of the traffic congestion situation is obtained and displayed from the traffic congestion information.
