Description

[Detailed Description of the Invention] [Summary] In television broadcasting, audio is played on the premise that viewers are watching television images. Therefore, when broadcasting a sports program or the like, it is sometimes difficult to know the content and situation from only the audio. In contrast, radio broadcasting conveys information to listeners only through audio, so
Even though it is only audio, the content is easy to understand.

While driving or working, in situations where you can sometimes see the television image, if you cannot see the image, you can occasionally watch the television image while listening to the radio sound if there is a corresponding radio program. is desirable. Therefore, the television receiver was equipped with a radio receiver, making it possible to switch between television audio and radio audio. Furthermore, channel selection is made easier by associating television channels with a memory that stores the frequencies of corresponding radio stations.

[Industrial application field]

TECHNICAL FIELD The present invention relates to a television receiver, and more particularly to a television receiver suitable for enjoying sports programs with corresponding radio broadcasts in situations where images can be viewed from time to time while driving a car or working.

[Conventional technology]

Although automobiles are now equipped with television receivers, drivers are unable to view the screen while driving for safety reasons, and can only occasionally view the screen when stopped at a traffic light or the like. A similar situation may also occur while you are working on something.

Television broadcasts are usually broadcast on the premise that viewers are listening to the audio while watching the television broadcast screen. For this reason, in sports programs and the like, it is difficult to understand the game situation and the like just from the audio. In comparison, in radio broadcasting, information is transmitted only through audio, so it is difficult to understand the match situation using only audio.
Radio broadcasts are easier to understand than television broadcasts.

Broadcasting stations for television broadcasting and broadcasting stations for radio broadcasting are generally affiliated with each other, and when broadcasting sports programs such as professional baseball, television broadcasting stations and radio broadcasting stations are related. Broadcasting stations often carry out broadcasts at the same time.

[Problem to be solved by the invention]

Up until now, television receivers and radio receivers have generally been separate devices, and some television receivers have a radio reception function, but you can listen to radio broadcasts while watching the television broadcast screen. I can't hear the audio. Therefore, as mentioned above, while driving or working, the television receiver was operated and sometimes the television screen was watched, and when the screen could not be seen, the television audio was listened to. Or, the current situation is that the television receiver is not operated and only the audio of the radio broadcast is listened to. Therefore, while driving or working, it is desirable to be able to listen to the corresponding radio broadcast while viewing the television broadcast screen.

When a car is equipped with a television receiver, it is generally also equipped with a radio receiver, and the situation described above cannot be said to be an effective use of these devices.

For this reason, it is conceivable to set the volume of the TV receiver to the lowest level, select the corresponding radio station, and output the radio sound, but this requires volume control to adjust the volume.
There is a problem that operations become complicated when changing channels, etc.

Furthermore, both television receivers and radio receivers are used normally, so if you want to listen to a radio broadcast while watching a television broadcast screen, you should tune in to the television broadcast channel. There is a problem in that it is necessary to select the radio broadcasting station to be broadcast, which is troublesome.

The present invention has been made in view of the above-mentioned problems, and it is possible to listen to the audio of a radio broadcast while viewing the television broadcast screen. The purpose is to make it possible to switch.

[Means to solve the problem]

In order to solve the above problems, a television receiver according to the present invention has a radio reception function and audio switching means. FIG. 1 is a diagram showing the basic configuration of a television receiver based on the present invention.

In FIG. 1, reference numeral 3 denotes a television receiver, which corresponds to a conventional television receiver that receives television broadcast signals, displays television broadcast images, and outputs television broadcast audio. The television receiver of the present invention includes, in addition to the conventional television receiver, a radio receiving section 1 that receives a radio broadcast signal and outputs the radio broadcast audio, and that switches between the television broadcast audio and the radio broadcast audio. Audio switching means 2 for outputting
This makes it possible to listen to radio broadcast audio while viewing television broadcast images.

Furthermore, in another aspect of the present invention, the radio receiving unit 1 includes presetting means for storing the frequency of a radio broadcasting station and automatically selecting a radio broadcasting station having the stored frequency, and selecting a television broadcasting channel. and this preset means can be associated with each other.

[For production]

As shown in FIG. 1, the television receiver of the present invention is capable of easily switching between the audio of television broadcasting and the audio of radio broadcasting using the switching means 2, thereby making it possible to view images of television broadcasting. It is now possible to listen to radio broadcasts while listening to radio broadcasts.

Furthermore, the radio receiving section 1 has a preset means, and this preset means can be associated with a television broadcast channel. Therefore, for example, in professional baseball broadcasts, etc., if the frequencies of the television broadcasting channel and the radio broadcasting station, which often broadcast the same game, are associated in advance using this preset means, after selecting the television broadcasting channel, When the switching means 2 switches from the audio of the television broadcast to the audio of the radio broadcast, the audio of the radio broadcast broadcasting the same game can be output.

This eliminates complicated channel selection operations.

〔Example〕

The purpose of the present invention is to provide a television receiver suitable for enjoying sports programs etc. while driving or working, and the present invention is not limited to use in a vehicle. This will be explained as an example.

In an on-vehicle radio receiver, in addition to manually selecting a broadcasting station using a dial or the like, there is also a method called a preset mechanism. In this system, frequencies of broadcasting stations are stored in correspondence with a plurality of buttons, and by pressing the button, a broadcasting station with the stored frequency is automatically selected. Furthermore, in what is called an auto-preset mechanism, the received radio broadcasting stations can be automatically stored in the preset mechanism in order of the strength of the received radio waves. In recent years, buttons have been replaced by electronic, progressive-scan selection mechanisms.

The radio receiving section 1 of the television receiver of this embodiment also has the above-mentioned preset mechanism.

FIG. 2 is a diagram of the front panel of the television receiver of this embodiment. As shown in the figure, this television receiver includes, in addition to switches such as a power switch 4 found in a normal television receiver, a radio channel selection button 6 paired with a television channel selection button 5; There are an audio selection switch 7 for switching between television broadcast audio and radio broadcast audio and selecting a radio station preset, a frequency display 8 for radio reception waves, and a frequency adjustment knob 9. The operation and operation of this television receiver will be explained.

First, refer to the TV and radio sections of newspapers, etc.
From everyday experience, for example, when broadcasting a professional baseball game, the channel of a television broadcasting station that broadcasts the same game is associated with the frequency of a radio broadcasting station.

Next, after turning on the power switch 4, the audio selection switch 7 is set to preset. In this state, the audio of the radio broadcast is output from the speaker. Then, the frequency adjustment knob 9 is used to adjust the frequency to the frequency of the radio station corresponding to the above-mentioned television broadcast station. After confirming that the frequencies match and the sound is normal, press the paired button below the button for the corresponding television station among the radio channel selection buttons 6. This associates the television broadcast station with the radio broadcast station. This is also done for other television broadcasting station channels and radio broadcasting stations.

After the above preset is completed, by switching the audio selection switch 7 from TV to radio while receiving a television broadcast, the radio broadcast station associated with the preset will be automatically selected for reception. . As this channel selection mechanism, the conventional brisset mechanism can be used as is.

Next, an embodiment in which an auto-preset mechanism is provided as the preset mechanism will be described. Auto preset is a method in which received radio waves are assigned to the channel selection button in order of strength within the frequency range of radio broadcasting, or received radio waves with a certain strength or higher are assigned to the channel selection button in order of frequency. Therefore, the order is independent of the television broadcast channel. Therefore, in this embodiment, a correspondence table as shown in FIG. 3 is used to associate television broadcast channels with frequencies stored by the auto-preset mechanism. The frequencies stored by auto preset are stored in auto preset memory.

In this case, first turn on the power switch, then press the auto preset activation button to store the frequency of the radio station in the auto preset memory. Next, select the frequency of the broadcasting station you want to associate with the television broadcasting channel from among the stored frequencies, set the correspondence mode using a separate switch, and select the television broadcasting channel and the auto preset memory. Press the corresponding button to store the channel and auto preset memory button pairs in the correspondence table.

If you switch the audio from the television broadcast audio to the radio broadcast audio while receiving a television broadcast,
For channels in the correspondence table, the audio of the radio broadcasting station of the frequency stored in the corresponding auto preset memory is automatically output. For channels not listed in the correspondence table, the radio broadcast of the frequency at the first memory location indicated by a in the figure is output. Although there are only four correspondence tables in FIG. 3, there are not so many radio broadcast stations that correspond to television broadcast channels, so four is sufficient. In practice, all of these mechanisms are realized using microcomputers.

〔Effect of the invention〕

According to the present invention, it is possible to realize a television receiver that allows one to listen to the audio of a radio broadcast while viewing the television broadcast screen with simple operations. Furthermore, during professional baseball broadcasts, etc.
By being able to easily switch between the audio of a television broadcast and the corresponding radio broadcast, even when driving or other situations where you cannot always look at the screen, you can listen to the radio broadcast, which makes it easier to understand the situation compared to the audio of the television broadcast.
