Abstract

PROBLEM TO BE SOLVED: To improve the operability of a channel-presetting device by enabling the device to preset a channel, even when the device does not know the channel number by making the channel pre-settable based on the divided display of all receivable channels. SOLUTION: When a user operates a POS setting button 16b of a remote controller, a CPU 15 controls tuners 3 and 4 so as to allow the tuners 3 and 4 to select all receivable channels and permits a video compression circuit 10 for auxiliary screen to compress video signals contained in the television signals of the selected channels at a compression rate required for displaying the signals in a divided state by supplying the video signals to the circuit 10. The CPU 15 also allows on-screen display of the setting information to be preset in pictures based on the video signals of each channel. Since the preset images of all the receivable channels are displayed on a main screen in a state where the images are divided into a plurality of parts, the user can confirm and select a settable image from the plurality of image displayed on the main screen and can preset a channel by operating a operating button 16d of the remote controller.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a presettable television receiver for setting a predetermined receiving channel for an arbitrary position number, and more particularly to a channel suitable for improving operability accompanying preset setting. It relates to a preset device.

[0002]

2. Description of the Related Art Currently, in television receivers sold in Japan, a preset method of setting a receiving channel corresponding to an arbitrary position number is generally adopted.

[0003] In a television receiver set by such a preset method, for example, among position buttons indicating position numbers such as 1 to 12 provided on a remote control transmitter, a user can select an arbitrary number of position buttons. When is pressed, the channel set at the time of presetting is selected by the tuning device.

However, in the conventional television receiver capable of performing the preset operation as described above, the preset operation of setting a desired channel to an arbitrary position number is very troublesome, and it is not an operation work that anyone can easily perform. Complicated operation work had to be performed.

[0005] Further, the above disadvantages will be described in detail.
In the above-mentioned television receiver, one channel of VHF (hereinafter abbreviated as CH) is placed in position 1 and 2CH of VHF is placed in position 2 by the manufacturer before shipping.
, And so on up to 12 channels of general VHF. For this reason, a user in the metropolitan area can receive all broadcasts after purchasing, except for UHF, without doing anything by himself, and does not feel the trouble of the preset described above.

However, for a user receiving UHF in a local area, it is necessary to set the position of each receiving channel by a preset operation, so that the trouble of the operation associated with the channel preset poses a problem.

Here, a general channel preset operation method will be described. For example, a preset operation is performed by the following operation method. Regarding the channel preset setting, for example, a case will be described in which, for example, 43CH of UHF is set to the position number 1 provided in the remote control transmitter, and the on-screen display in this case is set to 1.

Now, it is assumed that the user presses a channel setting button (also referred to as a POS setting button) provided on the remote control transmitter (not shown). Then, a control microcomputer (hereinafter, referred to as a CPU) in the television receiver.
Controls the memory and the on-screen display circuit to display a channel setting screen as shown in FIG. 8 on the screen of the device. The channel setting screen display is an on-screen display of information based on preset setting items such as a channel to be preset, a position number, and a display channel, and operation help information indicating an operation method based on the setting.

Then, the user operates a channel setting operation button provided on the remote control transmitter to select and display a desired "43CH" in order to receive a channel to be preset.

Next, the user operates a volume control operation button provided on the remote control transmitter to select "1" which is a channel number to be displayed on the screen.

Then, in order to set a preset position number, a position button (key button such as a numeric keypad) of position number 1 provided on the remote control transmitter is pressed.

Finally, by pressing a channel setting button provided on the remote control transmitter, the preset operation is completed, and the UHF43CH is moved to position "1".
Is preset and, unlike the example shown in the figure, "1" is set to be displayed on-screen when a channel is selected. In addition, when setting a channel to each of a plurality of positions, by repeating the operation after the operation button operation for the channel setting of the remote control transmitter,
Set similarly.

Although the channel preset operation as described above is a general operation method in the prior art,
In this method, since the user must select and set channels one by one, the operation is very complicated.

By the way, in the above-mentioned channel presetting method, the above-mentioned inconvenience may become remarkable due to different regions. For example, in the vicinity of Tokyo, many homes receive satellite radio waves obtained by converting VHF broadcasts to UHF because the received radio waves of VHF are not good. In such a home, while receiving UHF, the position number and screen display of the remote control transmitter (on-screen display)
Corresponds to "1", "3",
“4”, “6”, “8”, “10”, and “12” are easy to understand and convenient. However, there are cases where such a channel preset cannot be easily implemented. As an example of such a case, Table 1 shows the relationship between the VHF CH before conversion and the UHF CH after conversion in the southern region of Gunma Prefecture, and VHF before conversion in the adjacent northern region of Gunma Prefecture. Table 2 shows the relationship between the CH of the UHF and the CH of the converted UHF.

[0015]

[Table 1]

[Table 2] As can be understood from these tables (Tables 1 and 2), U
"1" is received in order from the channel with the lowest HF,
It is not necessarily sufficient to set “3” and “4”. That is, in these areas, the conversion channels of “1CH” and “3CH” are far from the numbers of “4 to 12CH” and the order is reversed, and it is very difficult to understand. Moreover, the converted UHF channel number is not published in newspapers, and is information that cannot be known to general users apart from the clerk of the store. Therefore,
When the user himself / herself performs the channel preset, the user can actually watch the broadcast contents and compare it with the program information described in the TV column such as a newspaper to obtain the UHF and VHF.
There is no other way to examine the interaction of the channel with the other. However, when similar programs are being broadcast,
It is difficult to make a determination easily, and it is necessary to repeatedly operate the channel setting operation button as described above to confirm the broadcast content.

As described above, the channel preset function according to the prior art is an inconvenient method in which if the user does not know the channel number, the operability is extremely poor and a complicated operation is required.

Incidentally, there is a preset method which is improved to reduce inconvenience in the above-mentioned channel preset method as much as possible. In this method, the channel number of each area is stored in the memory of the channel selection circuit at the manufacturing stage, and when the user selects the area, the reception channel of the area is automatically set at each position. This is a setting function. In this case, the relationship between the position number and the channel number is set in a combination determined by the manufacturer.

Therefore, if this automatic area setting function is used, many users can easily perform preset setting without complicated operation of channel presetting. However, even if this automatic area setting function is used, for example, when it is desired to receive a channel not set by the automatic area setting function, or to set a combination of the position number and the channel number to a combination different from the automatic area preset In such a case, it is necessary to set one channel for each position number with the user himself, and a complicated preset operation is required.

In an area where reception is very poor in an area where viewing is difficult and where a plurality of satellite stations receive radio waves, one channel is a satellite station and another channel is a B station.
Similarly, when a satellite station is selected according to a reception state, such as a satellite station, a complicated preset operation is required. In this case, even if the automatic region setting function is used, the VHF channel before conversion is changed. Even if they are the same, the UHF channels after conversion are different, so that it is impossible to cope with the automatic area setting function.

Further, in the prior art, a preset setting screen accompanying a channel preset is usually, for example, as shown in FIG. 8, for example, the entire main image (parent screen) based on a received television signal or external video signal, or a screen on the screen. Is displayed on the screen. Therefore, if all of the channels that can receive such a preset setting screen are divided into a plurality of sections at a time and displayed on the screen, the above-mentioned inconvenience can be expected to be reduced. As a conventional technology capable of dividing and displaying images of a plurality of channels on one screen,
For example, JP-A-56-51171 and JP-A-6-51171
Documents such as Japanese Patent Application Laid-Open No. 1-258581 and Japanese Patent Application Laid-Open No. 2-97181 have already been proposed, and some of them have already been put to practical use. However, these proposals are used only for the purpose of selecting a channel to be viewed, and are not currently used for a channel preset setting operation.

[0021]

As described above, a television receiver equipped with a conventional channel preset device employs a channel preset method of presetting a channel in accordance with a position number.
According to this method, the operation is complicated, and if the user does not know the channel number, the operation is more complicated, and the preset setting operation cannot be easily performed.

Therefore, the present invention has been made in view of the above-mentioned problems, and all the receivable channels are displayed in a divided manner, and presetting can be performed based on the divided display, so that the channel number is not known. However, an object of the present invention is to provide a channel preset device that can easily set a preset and improve operability.

[0023]

According to the present invention, there is provided a channel presetting device for receiving a television signal, selecting a predetermined channel of the received television signal, and selecting the channel. Screen synthesizing means for multi-displaying the images of a plurality of channels selected by the means on one screen, and performing preset setting by associating a position number with a receiving channel based on the multi-displayed video. Preset setting means, on-screen display means for superimposing and displaying setting information necessary for setting the preset on the image of the selected channel, and responding to the activation of the preset setting means, and The tuning means is controlled so as to tune sequentially, and the setting information is added to the images of a plurality of tuned channels. And control means for controlling said picture composing means and the on-screen display unit to on-screen display to those provided with the.

In the present invention, the screen synthesizing means and the on-screen display means provide, on one screen (on the main screen on which the main image is displayed), setting information necessary for presetting to the image of the receiving channel. The setting screen displayed on-screen is divided into a plurality of sections. In this case, the control means controls the tuning means to select a plurality of receivable channels. To set a preset, use the remote control's operation buttons to select a setting screen that can be set from the preset setting screen that is divided and displayed, and set the position number and the reception channel (display number) in association with each other. By doing so, the channel preset setting is performed. This makes it possible to perform the preset setting in which the position number and the receiving channel correspond to each other while checking the images of a plurality of receivable channels, so that the setting operation can be easily performed and the operability is improved. Becomes possible.

[0025]

The main-screen video compression circuit 9 performs signal processing necessary for displaying the input video signal on the screen and supplies the processed video signal to the switching circuit 11. At this time, when the channel preset setting mode is selected, the main screen video compression circuit 9 performs normal signal processing on the input video signal for the main screen, and displays the parent and child screens of a half screen. When the mode is selected, the input video signal is compressed and output so that the main image based on the video signal is displayed on a half screen (mainly on the left screen).

The sub-screen video compression circuit 10 performs signal processing required for displaying a sub-screen (small screen) on the input video signal, and provides the same to the switching circuit 11 as described above. At this time, when the channel preset setting mode is set, the sub-screen video compression circuit 10 compresses and outputs the input video signal so that an image based on the input video signal is displayed on the right screen as a sub-screen. Or receivable CH
When displaying all images, the video signals for each channel sequentially selected are subjected to compression processing at a compression ratio capable of multi-display as shown in FIG. 2, and then sequentially output at predetermined time intervals.

Although not shown, in the case of multi-display, the output of the sub-screen video compression circuit for each channel selection under the control of the CPU 15 is stored in a digital memory or the like connected to the sub-screen video compression circuit. By writing to a means (not shown) and reading out sequentially, multiple display as a still image becomes possible. The reading control of the digital memory is performed using a clock based on a synchronization signal separated from the video signal for the main screen.

The switching circuit 11 switches and synthesizes the video signal input under the control of the CPU 15 at a predetermined timing, or supplies only the input video signal for the main screen to a video drive circuit (not shown). Thereby, an image based on the output video signal can be displayed on the screen of the picture tube 12.

The audio is subjected to processing such as amplification for reproduction and output by the audio processor 13 so that the audio based on the received television signal is reproduced through the audio speaker 13. Has become.

By the way, the television receiver according to the present invention is provided with a remote control transmitter (hereinafter abbreviated as "remote control") 16 provided with various key buttons for facilitating a channel preset setting operation and executing various functions. Have been.

The remote controller 16 has a power button 16a for turning on / off the power, and a preset setting mode (a mode in which the preset on-screen display is executed and the channel can be preset, which is depressed when performing the channel preset setting). POS setting button 16b for activating the POS), a plurality of POS buttons 16c on which a position number at the time of selecting a channel is described, an operation associated with the channel preset setting, volume adjustment, or up. An operation button 16d used for a down channel selection operation is provided.

When any one of these key buttons is pressed, the remote controller 16 transmits key information based on the operation of the key button to the CPU 15 of the television receiver.

The CPU 15 fetches key information transmitted from the remote controller 16 or key information generated by a key operation unit (not shown) of the main body (not shown), and performs various operations such as channel selection and channel preset setting based on the key information. Perform control. For example, when the POS setting button 16c of the remote controller 16 is pressed, the CPU 15 controls the main tuner 3 or the sub tuner 4 so as to select a channel preset at the pressed position number.
When the operation by 6d is performed, the CPU 15 controls volume adjustment and up / down channel selection (channel switching). When a setting operation on various setting menu screens is performed by the operation button 16d, the CPU 15
Performs the setting based on this information and controls to perform the processing according to the setting.

The CPU 15 also controls the display of a sub-screen (in the case of a two-screen display), the control of multi-screen display, and the control of on-screen display. For example, the CPU 15 is connected to a memory 17 in which character information such as characters and figures, channel preset setting information, and the like are stored in advance.
5 reads out the information for on-screen display corresponding to the instruction of the key information from the memory 17, and outputs the read out information to the on-screen display circuit 18.

Although not shown, the on-screen display circuit 18 comprises a display control unit and a CG memory. The CG memory stores bitmap data corresponding to characters such as characters and graphics indicated by the on-screen display information. The display control unit controls the CG memory based on the on-screen display information to output an RGB signal for displaying the designated character at a display position indicated by the on-screen display information. That is, the on-screen display circuit 18 uses the RG

When the control signal is supplied to the switching circuit 11, the switching circuit 11 inputs the R signal based on the control signal.
The GB signal (character information) is superimposed on the composite video signal of the main screen and the sub-screen, and then the output signal is supplied to a video drive circuit (not shown) as described above, so that the screen of the picture tube 12 is on-screen. The display will be made.

By the way, in the television receiver adopting the channel preset device of the present invention, the channel preset setting screen for allowing the user to easily perform the channel preset setting operation by using the on-screen display function in the CPU 15. Can be displayed. Thus, a specific display control example in the CPU 15 will be described in detail with reference to FIGS.

In this embodiment, the user in the southern part of Gunma prefecture receives the radio wave of the satellite station converted into UHF as described in the prior art, and also changes the position number and display number of the remote controller in the newspaper. CH described in the TV column
In order to match the information, it is assumed that channel preset setting is performed so as to match the VHF CH before conversion.

Now, it is assumed that the user in the southern region of Gunma Prefecture presses the power button 16a of the remote controller 16 to turn on the power, and presses the POS setting button 16b (see FIG. 1) to set the channel preset as described above. I do. Then, the remote controller 16 transmits key information for instructing the POS setting mode to the CPU 15 of the device main body, and the CPU 15 receives the key information and recognizes the execution of the POS setting mode.

Then, the CPU 15 performs various controls based on the POS setting mode. For example, the CPU 15
When recognizing the OS setting mode, first, all the receivable channels are automatically selected using the main tuner 3 and the sub tuner, and an image based on all the channels is divided into one screen as shown in FIG. Control is performed so that each video signal is compressed by the compression circuit 10 and sequentially supplied to the switching circuit 11 using a digital memory (not shown) so as to perform multi-display. That is, image data as a still image is supplied.

At the same time, the CPU 15 reads from the pre-stored memory 15 the on-screen display information such as the pre-conversion CH number and position number, and the display number in Table 1 (satellite stations in the southern region of Gunma Prefecture). The on-screen display circuit 18 and the switching circuit 11 are controlled so that the on-screen display information is displayed on-screen corresponding to the screen based on the video signal of the selected channel. Thus, by supplying the synthesized signal to the video drive circuit (not shown), the channel preset setting screens 12a to 12f of the respective UHF channels are displayed on the screen as shown in FIG.

In the display example of the preset setting screen shown in FIG. 2, the CPU 15 displays an image having an aspect ratio of 16: 9 by dividing the screen vertically into three parts and horizontally into four parts and displaying each of the above-mentioned 12CH images on one screen. It is a display screen at the time of controlling the compression rate of a compression circuit. Also, different from such a multi display example, the channel preset screens 12a to 12
f may be multi-displayed.

FIG. 3 is an enlarged view of one of the plurality of channel preset setting screens (screen 12a) thus displayed. That is, on each of the channel preset screens 12a to 12f, a setting including characters and numerals of each "reception channel" of the UHF that needs to be preset, the "position number" to be preset, and the "display number" to be displayed on the screen. The display unit 22 is displayed on-screen, for example, at the upper right of the screen.

When the television receiver has only one tuner, the CPU 15 controls to display all the multi-screens (preset setting screens 12a to 12f) as still images. It is also possible to control so that the images are sequentially updated at predetermined time intervals. Further, in the present embodiment, since two tuners 3 and 4 are provided, among the channel preset setting screens 12a to 12f, the screen in which the preset setting is possible is a complete moving image. It is possible to switch the tuner so as to perform display control. In this case, as for the audio, the CPU 15 controls the AV switching circuit 7 so as to output only the audio of the screen in a presettable state.

Therefore, the channel preset setting screen can be displayed on the screen by the channel selection control and the display control by the CPU 15.

The number of channels to be displayed at one time may be controlled so as to match the number of POS buttons (position buttons) 16c provided on the remote controller 16, in which case the operability is further improved. It becomes possible. If the number of receivable channels is too large to display all at once, it is displayed as the next page as shown in FIG. 2, and information for allowing the user to recognize that there is a next page is displayed in a message. The part 12g is displayed on-screen. Of course, when there is no next page, as shown in FIG. 2, the message display section 12g indicating "there is no next page" is displayed on-screen.

Further, in order to easily distinguish a setting screen (hereinafter referred to as an active screen) in a channel presettable state as described above from other setting screens, for example, the active screen is shown in FIG. As shown in the figure, the frame display unit 23 in which the color arrangement is changed is displayed, or the character colors of “channel”, “position”, and “display” are changed, and further, “position” in which a number is input in a preset setting item -Control may be performed so that the cursor corresponding to the position at "display" blinks.
As a result, it is possible to obtain a channel preset setting screen in which the setting operation is easy.

Next, a setting operation method using the channel preset setting screen will be described.

Now, assuming that the channel preset setting screen shown in FIG. 2 is displayed on the screen, the user next selects an active screen (a screen in a settable state) from a plurality of divided setting screens. At this time, to select and move the active screen, the remote controller 1 shown in FIG.
The operation is performed using the six operation buttons 16d, and the preset setting items are sequentially set using these operation buttons 16d.

For example, as shown in FIG.
If the user selects the H setting screen 12b as the active screen, the user operates the operation button 16d or the POS button 16d.
By operating c, the preset items “position” and “display” of the setting display section 22 are set in order. At this time,
Assuming that the “position” number is set to “10” and the “display” number displayed on the screen is also set to “10”, the screen after setting is as shown in FIG. Thus, the channel preset setting based on CH33 is completed.

If there is another setting screen for which a channel preset needs to be set, the active screen is moved and the setting items are set in the same manner.

By such a setting operation, channel preset setting can be easily performed.

In the present embodiment, at the time of preset setting, the message display section 24 such as "can be set channel" indicating that the channel can be set by the on-screen control of the CPU 15 is turned on for the active screen. Since the screen is used, the user can easily confirm the active screen. In addition, about this active screen,
If the control is performed so as to reproduce the sound in the receiving channel, the broadcast contents can be more easily confirmed.

Further, a configuration may be adopted in which the display control by the CPU 15 can be performed so that only the active screen of the plurality of divided display screens is switched to the large screen and displayed. In this case, a screen mode (4: 3 display / 16:
9) is operated using an operation button for switching the screen display mode. In the case of a television having only one tuner, control is performed so that the screen at the time of switching to the large screen is displayed as a complete moving image. I do. Thereby, by performing the setting on the active screen on the large screen, it is possible to easily confirm the broadcast content of the CH to be preset, and furthermore, in the case of displaying the moving image and outputting the sound, The channel preset setting can be performed while checking the moving image and the sound.

Further, in this embodiment, when all the channels that can be automatically received are selected, there is a possibility that channels that do not need to be preset because of poor reception conditions may be selected. However, in such a case, the display can be controlled by the CPU 15 so as not to display the image of the channel having a poor reception state. For example, a screen to be erased is temporarily set as an active screen, and an image based on the channel is erased by pressing an operation button such as “video” provided on the normal remote controller 16 (not shown). Channel selection and display control are performed so that the image of the channel is displayed in a raised manner. This makes it possible to arrange a plurality of divided setting screens into screens based on necessary channels only, thereby further improving operability.

Therefore, according to the present embodiment, as described above, the user who receives the UHF-converted satellite radio waves can compare all the channels at the same time without recognizing the channel numbers. Newspaper TV
If the program is confirmed in a column or the like, it is possible to easily recognize and determine which channel of the VHF corresponds to the broadcast program. Also, even if the channel number is known, the channels that can be received are displayed on the screen at once, and channel preset settings can be made in that state, eliminating the need to adjust channels one by one, simplifying the operation procedure. And operability can be improved.

In the present embodiment, the channel preset setting in the case of receiving the radio wave of the satellite station obtained by converting the VHF broadcast in Tokyo into UHF in the Kanto area as described above has been described. It is possible to apply even if it does. For example, when a VHF broadcast in Tokyo is received on a CATV in the Kanto area, it is desired that the position number of the remote controller 16 and the display on the screen match the original VHF channel number. Therefore, even in such a case, by adopting the setting method according to the present invention, the channel setting operation by the user can be made easier and the operability can be improved as compared with the conventional method. Not only a John receiver but also a CATV receiver can be used.

The present invention can be applied to a VTR connected to a television receiver, and can be applied to all receiving devices capable of receiving television signals. Obviously, a similar effect is obtained.

By the way, recently, "Perfect TV"
Digital satellite broadcasting is being implemented.
Many digital satellite broadcast stations, such as "Dirik TV" and "J Sky B", are scheduled to participate. Accordingly, the number of channels increases to several hundreds of channels, and the channel selectivity for the user increases. In addition, since it becomes possible to receive digital satellite broadcasts with a common receiving device as a device, the user can use the most frequently viewed channel among channels that can be received (a channel with a free channel and a receiving contract). It is desired to preset channels for desired position numbers or program genres.
Even in such a case, the present invention can be applied. An example of such an embodiment will be described with reference to FIGS.

FIGS. 6 and 7 show an embodiment in which the channel presetting device according to the present invention is incorporated in a television receiver for digital satellite broadcasting. FIG. 6 shows a case where preset channels are displayed as icons by genre. FIG. 7 is a screen display diagram showing a channel preset setting screen when the movie shown in FIG. 6 is selected.

In this embodiment, unlike the above embodiment in which a desired channel is preset according to a position number, for example, as shown in FIG. 6, "movie", "sport", "news", "music", "music" A channel preset of a desired channel is performed for each genre such as “travel”, “gourmet”, and “shopping”.

For example, the memory 17 shown in FIG. 1 stores on-screen display information such as pictograms and symbols for each genre described above, and when a setting button (not shown) of the remote controller 16 is pressed, the CPU 15 On-screen display information is read, and the on-screen display circuit 18 is controlled to display a channel preset setting table of contents for each genre as shown in FIG. 6 on the screen.

In the case of channel presetting, when the user selects one of the icons in the genre display sections 25a to 25h of the table of contents, the CPU 15 sets the receivable channel of the selected genre in the same manner as in the above embodiment. Is controlled so that the setting screens 26a to 26f are displayed in a plurality of segments at a time. At this time, the channel to be received for each genre is identified by the CPU 15 by using information such as program information and identification information included in the received signal, and channel selection control is performed. As a result, all receivable channels according to the genre can be selected, and the on-screen display can be performed at once.

Assume that the genre display section 25a of "movie" shown in FIG. 7 is selected by the user's operation.
Then, the CPU 15 displays a channel preset setting screen 26 for each genre as a next screen.

Then, the user selects a screen (one of the screens 26a to 26f) based on the channel desired to be preset in the "movie" genre from the setting screen 26 using the remote control operation button 16d. ,
Further, similarly to the above-described embodiment, the number of the "position" and the number of the "display" to be displayed on the screen are set, and the channel setting in the genre of "movie" is performed.

Also, in the case of preset setting for other genres, it is possible to preset the desired channel for each selected genre by performing the same setting operation as described above.

When a plurality of channels are preset for each genre, control may be performed so as to assign a priority to the preset. In this case, when the user selects a genre to be viewed, the priority is set. , The channel of the genre selected on the basis of is selected and displayed, so that there is an effect that the channel selection operation can be easily performed without any hesitation.

Therefore, according to the present embodiment, even when digital satellite broadcasting having multiple channels is received, the channel preset setting can be easily performed similarly to the above-described embodiment, and the operability is improved. It becomes possible.

[0074]
