Abstract

PURPOSE:To improve the operability of a receiver which transmits the name of a receiving broadcasting station by determining an area by the combination of frequencies at which channel selections are made successively by automatic tuning and a comparative decision. CONSTITUTION:When an operation switch 3 is operated in order to set the name of an automatic broadcasting station, a muting circuit 5 operates to inhibit the transmission of a regeneration output from an electric tuner 1. Then, a frequency f0 at which reception is performed at present is stored in the memory 20 in a microcomputer 2 and automatic tuning is carried on to store reception frequencies in the memory 20 successively. When the frequency f0 is detected by making one round of a reception band, the automatic tuning operation is stopped and a decision on the area is made on the basis of the combination of the stored reception frequency to set the name of a broadcasting station corresponding to a reception frequency suitable for the area.

However, even on the same frequency, different broadcasting stations may exist in different locations. For example, TV channel U12 is a commercial broadcaster in Tokyo, but in Osaka it is NHK Educational Television. A similar thing may also occur with radio signals such as FM. Therefore, it is necessary to store several broadcasting station names for one frequency, and configure the system so that only a certain broadcasting station name is output depending on the area where the signal is currently being received. In order to achieve this, it is conceivable to use a predetermined signal for each region, but whether you use a switch or program it by inputting a predetermined decoded signal, the end result is that the user The disadvantage is that it requires manual operation, is difficult to operate, and can lead to erroneous operation.
OBJECTS OF THE INVENTION The present invention aims to eliminate the above-mentioned drawbacks, and aims to provide a receiving device that can automatically determine the current receiving area and output the correct broadcasting station name for a certain frequency by voice. purpose.

Structure of the Invention The present invention includes an electronic tuner section that can automatically sweep, a storage means that stores the correspondence between broadcasting station names and signals, and combinations of reception signals that can be received for each region, and a storage means that stores reception signals from the electronic tuner section. and a discriminating means for blanking out and temporarily retaining the output data indicating the area, and the discriminating means compares the data of the set of received signals received by the automatic sweep with the data in the storage means to determine the area. This system is configured to specify a broadcasting station and output the audio using a voice synthesizing means.

DESCRIPTION OF THE EMBODIMENTS FIG. 1 is a block diagram of the main parts of the present invention. Reference numeral 1 denotes an electronic tuner, which is connected to a microcomputer (hereinafter referred to as microcomputer) 2 through a connection 1b containing frequency detection digit signals and segment signals and an autotuning control connection 1C. Further, one of the input terminals of the microcomputer 2 is connected to an operation switch 3 for automatic broadcasting station name setting, which achieves the object of the present invention. Furthermore, the microcomputer 2 and the voice synthesis section 4 are connected by a connection 2a that includes signals for address designation and start of voice output, and the voice synthesis section 4
The audio signal is output to terminal 6. This microcomputer 2 has a ROM 2 that stores data regarding frequencies, broadcasting stations, etc.
0 is built-in. On the other hand, the reproduction output a1a from the electronic tuner is connected to the output 5a of the muting circuit 5, which is connected to the output line 2b from the microcomputer 2 and the output line 1d from the electronic tuner 1. It is configured to control muting of. Further, FIG. 2 shows a flowchart of main parts of the microcomputer 2 used in the present invention.

Hereinafter, the operation will be explained based on the above-mentioned FIGS. 1 and 2. First, the operation of outputting the name of the broadcasting station being received by the electronic tuner 1 will be briefly explained.

The frequency being received by the electronic tuner 1 is input to the microcomputer 2 as a frequency display segment signal and digit signal through the connection 1b, and then the broadcasting station name for this detected frequency is determined based on the data in the ROM 20. It is determined. When this process is completed, an address designation signal for operating the sound synthesis section 4 and an audio output start command signal are output to the output connection 2a from the microcomputer 2, and based on these signals, broadcast to the audio output terminal 6 of the speech synthesis section 4. The station name will be output. The above is normal operation.

Next, when several broadcasting stations use the same frequency in different areas, the operation of correctly selecting and uttering the name of the broadcasting station in the current receiving area will be described. First, when the operation switch 3 for automatic broadcasting station name setting described above is operated, the program at step 21 of the flowchart of FIG. 2 is started. When the program is started, first in step 21 the muting circuit 5 is operated to prevent the reproduced output from the electronic tuner 1 from being transmitted to the next stage (not shown). Next, in step 22, the currently received frequency f is determined. is stored in the temporary storage means (RAM) in the microcomputer 2, and then automatic tuning is started in step 23. This automatic tuning is performed using connection 1c in Figure 1.
This is done by issuing a control signal from the microcomputer 2 to the electronic tuner 1 via the microcomputer 2. In this automatic tuning, the reception frequency is automatically swept, and when the next broadcasting station signal is received (Stella 7" 24), the reception frequency is stored in the RAM of the microcomputer 2 (at a different address) in step 25. Automatic tuning is started again in step 26.Therefore, during the above operation, several reception frequencies are detected and stored until the frequency f is detected again (step 27).In steps 24 to 26, the reception band or the receiving band without detecting any other stations during reception, and again detecting the frequency f. Step 27
The process then proceeds to step 28 to stop the automatic tuning operation, and detection is performed in steps 24 and 25.

Based on the stored combination of several reception frequencies, it is determined in step 29 which region it is in, and a broadcasting station name corresponding to the reception frequency suitable for that region is set. Furthermore, the voice synthesizer 4 is driven to vocalize the name of the broadcasting station in step 30, muting is canceled in step 31, and the frequency f is set. The playback output of the broadcast station is sent to the next stage and the broadcast can be listened to. Note that step 33 displays when the above automatic tuning operation is in progress. Normally, it takes a few seconds to sweep within one band, and the output is muted during this time, so this is done in order to avoid causing anxiety to the operator. is also valid.

As described above, according to this embodiment, since the combinations of broadcasting stations of frequencies receivable in the area are stored, comparisons are made with the combinations of frequencies sequentially selected by automatic tuning initiated by the operation. By determining
This is very convenient as it allows you to determine the broadcasting stations in that area. Therefore, this receiving device is suitable for television receivers, in-vehicle tuner devices, etc., and can greatly improve operability.

Effects of the Invention The present invention stores data regarding the correspondence between broadcasting station names and their broadcasting frequencies and the combinations of receivable broadcasting station names in each area in a storage means, and automatically selects the electronic tuner unit in sequence by sweeping the data. The selected frequencies are temporarily stored, and the area in which the station was received is determined by comparing the selected frequencies with the data in the storage means, and this is then transmitted to the broadcasting station in the form of voice using voice synthesis means. Since the system is configured to announce the name of the broadcast station, if different broadcast stations in different areas are broadcasting on the same frequency, the name of the broadcast station can be automatically output as a voice when receiving in that area. , it is possible to provide an excellent receiving device that can greatly improve operability.
