Description

TECHNICAL FIELD The present invention relates to a channel display device of a broadcast receiver such as a television receiver or a radio.

[Prior Art] FIG. 3 shows an example of a display on a channel display device of a conventional television receiver. In FIG. 3, (7A) is a CRT screen and (1) is a channel position. , 1 to 29 and 0 in total, 30 positions are displayed in Arabic numerals on the screen (7A) of the CRT. (2) is the display information called real channel, which displays the 2-digit Arabic number from 0 to 99 on the screen (7A) of the CRT. The user can set it for each channel position. "---" if not set
Display a blank symbol that becomes.

(3) is an identification symbol, and this identification symbol (3) is always displayed on the screen (7A) of the CRT so that the viewer can identify that the display information (2) is a real channel.

For example, in the Kansai area, if you want to store, or preset, the entrainment information for NHK education in the sixth channel position, if you preset "12" as the display information (2), the screen display as shown in Fig. 3, At the time of tuning, it turns out that the 6th channel position is 12 channels.

FIG. 4 is a block diagram showing a schematic configuration of the television receiver for displaying the screen as described above. In FIG. 4, the broadcast signal input from the antenna (4) is selected and tuned by the tuner (5), CR via signal processing circuit (6)
Video is reproduced and output to T (7) and sound is output to the speaker (8).

A user or the like using the television receiver (9) having such a configuration performs presetting of tuning information and display information, selection of channel position, volume control, etc. through the operation panel (10). In addition, the microcomputer (11) operates according to the operation contents of the user,
It controls the tuner (5) and the signal processing circuit (6), writes / reads the contents of the memory (12), and generates display information. The display information is superimposed on the image as a signal to be displayed on the screen of the CRT (7) in the signal processing circuit (6).

FIG. 5 is a flow chart showing the operation of the micro computer (11) at the time of channel selection in the conventional television receiver, which corresponds to the channel position determination and the determined channel position with channel selection. After the contents are read from the memory (12) and tuning is performed, the channel position (1), the identification symbol (3) and the display information (2) are displayed on the screen (7A) of the CRT (7).
Displayed above. The display time (T) is set in advance, and after T seconds have elapsed, those displays are erased.

[Problems to be Solved by the Invention] Since the conventional channel display device of the broadcast receiver is configured as described above, when the channel position for which the display information (2) is not set is selected, FIG. As shown in, there is a drawback that the channel position (1) and "CH ---", which indicates that the real channel is not set, are displayed, and the display is conspicuous.

Even with a broadcast receiver that has an auto-preset function that automatically presets tuning information for multiple broadcasts by repeating automatic sweep tuning and memory, the effort of presetting tuning information can be saved, but the The presetting needs to be performed manually by the user or the like, and depending on the user or the like, there is a case that the real channel is not properly preset by being tuned and received by the auto presetting. Even in such a case, it is unavoidable that the display information (2) and the identification symbol are displayed as "CH ---" as described above, which is a visual obstacle.

The present invention has been made in order to solve the above problems, and it is a channel of a broadcast receiver which can be made blank when the display information is not set, and at the same time the identification symbol can be made blank to prevent a noticeable display. An object is to provide a display device.

[Means for Solving the Problems] The channel display device of the broadcast receiver according to the present invention is
It is configured to determine whether the display information corresponding to the channel position is blank, and when the display information is blank in the determination result, the identification symbol for identifying the display information is also blank. Is characterized by.

[Operation] According to the present invention, when the display information is not preset corresponding to the channel position, it is determined that the display information is blank in the operation at the time of channel selection, and the identification code is determined based on the determination result. Will also be blank and only the selected channel position will be displayed.

[Embodiment of the Invention] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a flow chart showing the operation of the microcomputer (11) at the time of channel selection in the channel display device of the broadcast receiver according to the embodiment of the present invention, which is different from the conventional example shown in FIG. The display after tuning is divided into the display of the channel position and the display of the identification symbol and the display information, and between the both displays, it is programmed to judge whether the display information is blank or not. That is the point.

According to such a program, if "12" is preset as display information in the sixth channel position (1), for example, as shown in FIG. 3, the channel position (1), The identification symbol (3) and the display information (2) are displayed as in the conventional case. However, if the display information corresponding to the channel position is not set, the identification symbol also becomes blank based on the determination result that the display information is blank, and as shown in FIG. 2, the channel position (1) Only can be displayed on the screen (7A) of the CRT (7).

Since the configuration of the receiver is the same as that in FIG. 4, detailed description and illustration thereof will be omitted.

In addition, if a program that presets the display information of all channel positions to a blank when the auto preset operation is performed is added to the one that has the auto preset function, the auto preset At the time of the end, the display state is the same as the receiver that displays only the channel position. At this point, if the user decides that it is sufficient to display only the channel position, the preset is completed.If the user wants to display the real channel as well, the number of channels that are automatically preset to each channel position is determined by the number of channels. The same effect as that of the above-described embodiment can be obtained by sequentially presetting the real channels while checking whether there is a program table or the like.

In the above embodiment, the channel position and the display information are Arabic numerals and the identification symbol is an English character, but these three displays are alphanumeric, katakana, hiragana, kanji and Japanese. Characters, other foreign language characters, or a combination thereof may be used.

Also, although the case where the channel position and the real channel are displayed at the same time and the display is erased at the same time is shown, for example, after the channel position is displayed first, the real channel is displayed. It may be displayed with a shift.

[Effects of the Invention] As described above, according to the present invention, when the display information is not set, the display information and its identifying symbol can be blanked to prevent the appearance on the screen. In other words, this makes it possible for the user to arbitrarily set the display at the time of channel selection to the display of only the channel position and the display information of both the channel position and the real channel. Therefore, it is possible to inexpensively provide a display device adapted to the preference of local users.
