Description

The present invention relates to a channel selection device and a television capable of executing sequential channel selection for selecting channels in the order of channel numbers, and a channel selection control method for executing the sequential channel selection.

Today, in the situation where television broadcasting is being carried out in various broadcasting formats such as BS broadcasting and CS broadcasting in addition to terrestrial broadcasting, the number of channels of television broadcasting has increased so that viewers have difficulty in selecting it. Yes. Also, among these channels, there are many paid channels that require a viewing contract, and even though it is impossible to view without a contract, it is necessary to select a channel up or down (sequentially). Even those channels that cannot be viewed are selected. For this reason, there is a disadvantage that it takes a long time to select a desired channel. A digital broadcast receiver disclosed in Japanese Patent Laid-Open No. 10-215441 is known as a technique that can eliminate such inconvenience. In this digital broadcast receiver, when the channel up key or the channel down key is operated in the state where the viewable channel mode is set, the channel up / down is executed only for the channels that can be viewed by the tuner. For this reason, channels that cannot be viewed are not selected,
It is possible to select a desired channel in a relatively short time.
Japanese Patent Laid-Open No. 10-215441 (pages 4-9 and 2-11)

However, the conventional digital broadcast receiver has the following problems. That is, in this digital broadcast receiver, channel selection time is shortened by executing channel up / down for only viewable channels. On the other hand, for example, when contracting viewing of pay channels in CS digital broadcasting, there are many pack contracts where many pay channels can be viewed at a low price. It contains a lot of channels that never happen. Therefore, it is still difficult to select a desired channel in a short time for a conventional digital broadcast receiver that targets all the channels that can be viewed, including channels that are rarely viewed. There is a problem that there is.

In this case, a method may be considered in which a channel with low frequency of viewing is set in advance on the setting screen as a channel selection exclusion channel, and the channel selection exclusion channel is skipped at the time of channel up / down. However, with this method, it is difficult to determine which channel is skipped. For example, when a large number of channel exclusion channels are set,
Even if the user wants to view the skipped channel, there is a disadvantage that it is difficult to grasp that the channel is set as a channel exclusion channel. Further, when changing the setting of a channel set as a channel selection exclusion channel to a channel up / down target, it is necessary to switch to the setting screen and reset the setting, resulting in inconvenience that the operation becomes complicated.

The present invention has been made in view of such problems, and it is a main object of the present invention to provide a channel selection device, a television set, and a channel selection control method that can easily grasp a channel that has been skipped at the time of skipping channel selection. And It is another object of the present invention to provide a channel selection device, a television set, and a channel selection control method that can easily set channels excluded from channel selection as targets for channel selection.

In order to achieve the above object, a channel selection apparatus according to the present invention includes a reception unit that receives a broadcast signal, a channel selection unit that selects a channel of the broadcast signal to be received by the reception unit, and the channel selection unit according to a channel switching operation. And a control unit that executes sequential channel selection for selecting the channels in order of channel numbers, and channel selection exclusion set as a channel to be excluded from the target of sequential channel selection A storage unit that stores channel selection information capable of specifying a channel; and when the control unit causes the channel selection unit to execute the sequential channel selection, the control unit performs the next channel selection immediately before the channel switching operation. When the channel after the next rank corresponds to the channel exclusion channel specified based on the channel selection information, the channel after the next rank is skipped and the channel selection is excluded. Together to execute interlaced tuning for further selecting a channel of the next rank not correspond to channel the tuning unit to display the channel number of the interlaced channel on the display unit.

Further, the television according to the present invention includes a receiving unit that receives a broadcast signal, a channel selecting unit that selects a channel of the broadcast signal to be received by the receiving unit, and a channel selection unit that controls the channel selecting unit according to a channel switching operation. A television including a channel selection device having a control unit that executes sequential channel selection in order of channel numbers and a display unit that displays video based on the broadcast signal, and is excluded from the target of sequential channel selection A storage unit that stores channel selection information that can identify a channel excluded channel that is set as a channel to be selected, and the control unit immediately before the channel switching operation when the channel selection unit executes the sequential channel selection. If the channel after the next rank of the channel selected for the channel corresponds to the channel excluded channel specified based on the channel selection information, Causes the channel selection section to execute the channel selection that skips the channels after the ranking and does not correspond to the channel excluded from the channel selection, and selects the next channel, and displays the channel number of the channel skipped on the display unit. Let

In the channel selection control method according to the present invention, the channel selection unit that selects the channel of the broadcast signal to be received by the reception unit is controlled according to the channel switching operation to execute the sequential channel selection in the order of the channel numbers. In the channel selection control method, when the channel selection unit performs the sequential channel selection, the channel after the channel next to the channel selected immediately before the channel switching operation is subject to the sequential channel selection. When the selected channel is excluded from the channel selection, the skip channel selection is performed to skip the channel after the next rank and select the channel of the next rank not corresponding to the channel excluded channel. The channel selection unit executes the channel number and the channel number of the skipped channel is displayed on the display unit.

According to the channel selection device, the television, and the channel selection control method, the channel selection unit sequentially performs the channel selection when executing the channel selection, and the channel number of the skipped channel is displayed on the display unit. It is possible to reliably notify the user of the channel that has been skipped during channel selection. Therefore, for example, even when the user forgets which channel has been set as the channel selection exclusion channel, the user can surely grasp the set channel.

Further, in the channel selection device according to the present invention, in the channel selection device, the control unit selects the selected channel when the channel number displayed on the display unit is selected. To tune in.

According to this channel selection device, when the channel number displayed on the display unit is selected,
The controller selects the selected channel by simply selecting the channel number on the screen on which the video (TV image) based on the broadcast signal is displayed by selecting the selected channel. You can switch to the channel with the specified channel number. Therefore, for example, as compared with the method of inputting the channel number of the channel selection exclusion channel using a numeric key, the channel can be switched in a short time without causing an input error.

Further, in the channel selection device according to the present invention, in the above channel selection device, when the channel number displayed on the display unit is selected and a predetermined setting operation is performed,
The setting of the selected channel is changed to the channel selection target channel that is the target of the sequential channel selection.

According to this channel selection device, when the channel number displayed on the display unit is selected and a predetermined setting operation is performed, the control unit changes the setting of the selected channel to the channel to be selected. Thus, the selected channel can be changed to the channel to be selected simply by selecting the channel number on the screen on which the video based on the broadcast signal is displayed and performing a predetermined setting operation. For this reason, compared to the method of switching to the setting screen and resetting,
Settings can be changed easily in a short time.

Further, in the channel selection device according to the present invention, in the channel selection device, the control unit selects the channel number of the channel to be selected displayed on the display unit and performs a predetermined resetting operation. When performed, the selected channel is set as the channel exclusion channel.

According to this channel selection device, when the channel number of the channel to be selected displayed on the display unit is selected and a predetermined resetting operation is performed, the control unit excludes the selected channel from channel selection. By selecting the channel number on the screen where the video based on the broadcast signal is displayed and performing the specified resetting operation, the channel whose setting has been changed to the channel selection target channel is selected. Can be set again. Therefore,
For example, even if the channel selection exclusion channel is erroneously changed to the channel selection target channel, it can be easily restored to the original setting.

Further, in the channel selection device according to the present invention, in the channel selection device, the control unit selects the channel number of the channel to be selected displayed on the display unit and performs a predetermined channel selection operation. When performed, the selected channel is tuned to the tuning unit.

According to this channel selection device, when the channel number of the channel to be selected displayed on the display unit is selected and a predetermined channel selection operation is performed, the control unit sets the selected channel to the channel selection unit. By selecting the channel, for example, when changing the setting of multiple channel exclusion channels displayed on the screen to the channel to be selected, the channel is not selected (cannot be switched) simply by selecting the channel number. The channel selection exclusion channel can be changed to the channel to be selected while watching the video of the channel selected by the interlace selection. Further, according to this channel selection device, only the channel whose setting has been changed to the channel to be selected can be set as a channel selection target (channel switching target). Even in the case of sequential channel selection, it is possible to reliably select the channel without jumping over.

Hereinafter, the best mode of a channel selection device, a television, and a channel selection control method according to the present invention will be described with reference to the accompanying drawings. A projection television (hereinafter also simply referred to as “TV”) 1 shown in FIG. 1 is an example of a television according to the present invention, and includes a main body 2 and a remote controller 3 as shown in FIG. .

The channel selection processing unit 11 corresponds to the channel selection unit in the present invention, and selects a channel of the broadcast signal Sb to be received by the tuner 12 under the control of the control unit 22. The tuner 12 corresponds to a receiving unit in the present invention. As an example, the tuner 12 is configured to be able to receive BS digital broadcasting, 110-degree CS digital broadcasting, terrestrial digital broadcasting, and terrestrial analog broadcasting, and is selected by the channel selection processing unit 11. The broadcast signal Sb of the selected channel is extracted from the broadcast wave received by the antenna not shown in the figure and output to the video / audio processing unit 14.

The storage unit 13 stores association data in which each direct channel selection key 32 (see FIG. 2) of the remote controller 3 is associated with a channel (channel number) assigned to each direct channel selection key 32. The storage unit 13 also stores channel selection data Ds (channel selection information in the present invention) used in the up / down channel selection processing 50 (see FIG. 3) executed by the control unit 22. In this case, the channel selection data Ds selects a channel in the ascending order of channel numbers (hereinafter, this channel selection method is also referred to as “up channel selection”), and selects a channel in descending order of channel numbers. Channel selection in sequence (Hereinafter, this channel selection method is also referred to as “down channel selection” or “up channel selection” when not distinguished from “up channel selection”)
The channel to be selected (channel to be selected) and the channel to be excluded from the up / down channel selection (channel to be excluded from selection) can be specified. Specifically, FIG.
As conceptually shown in Fig. 4, a channel exclusion channel (channels 221 to 223 shown in the figure) has a flag ("Yes" in the figure) indicating that the channel is to be skipped at the time of channel selection. ”Flag). Further, a channel (“No” flag in the figure) indicating that the channel is selected (not skipped) at the time of up / down channel selection is attached to the channel to be selected.

The video / audio processing unit 14 outputs the video signal Sp1 and the audio signal Ss1 based on the broadcast signal Sb output from the tuner 12 to the video output unit 15 and the audio output unit 17, respectively, under the control of the control unit 22. The video output unit 15 generates a video signal Sp2 for video display based on the video signal Sp1 output from the video / audio processing unit 14 or video data stored in a memory outside the figure, under the control of the control unit 22. And output to the display unit 16. As an example, the display unit 16 includes an optical engine and a screen panel (both not shown), and the projection light that is light-modulated based on the video signal Sp2 from the video output unit 15 is applied to the screen panel from the back side. Various images are displayed by projecting.

The audio output unit 17 amplifies the audio signal Ss1 output from the video / audio processing unit 14 and outputs the amplified audio signal Ss2 to the speaker 18. The speaker 18 outputs a sound based on the sound signal Ss2 output from the sound output unit 17. The “voice” in the present specification includes not only a human voice but also various “sounds” such as bird calls, wind sounds, and music. Light receiver 1
9 receives the infrared signal Si output from the remote controller 3 and outputs an operation signal So. The key input processing unit 20 outputs a control signal Sc corresponding to the operation signal So output from the light receiving unit 19 to the control unit 22. The timer 21 operates according to the control of the control unit 22, and outputs a timer signal St to the control unit 22 when a display time t set by the control unit 22 has elapsed.
The control part 22 controls each part which comprises the television 1 according to the channel selection control method which concerns on this invention.
In addition, when the control signal Sc corresponding to the channel up key 33a or the channel down key 33b of the remote controller 3 is output from the key input processing unit 20, the control unit 22 performs FIG.
By executing the up / down channel selection processing 50 shown in FIG. 4, the channel selection processing unit 11 is caused to execute up / down channel selection. In this case, when performing the up / down channel selection, the control unit 22 skips the above-described channel selection exclusion channel and selects a channel after the next rank (hereinafter, this channel selection method is referred to as “skip”). 4) is executed by the channel selection processing unit 11 and the skip setting / cancellation processing 70 shown in FIG. 4 is executed in accordance with a control signal Sc corresponding to a predetermined operation key on the remote controller 3.

The remote controller 3 is formed separately from the main body 2 as shown in FIG. The remote controller 3 is also referred to as a “channel up / down key 33” when the power key 31, the 12 direct channel selection keys 32, the channel up key 33a, and the channel down key 33b (hereinafter, both keys 33a and 33b are not distinguished). ), Cursor keys 34a-34d
(Hereinafter referred to as “cursor key 34” when not distinguished), skip setting key 35,
Various operation keys such as enter key 36 and volume adjustment key 37 are arranged, and when these operation keys are operated, infrared signal Si corresponding to each operation key is output (transmitted).

Next, the overall operation of the television 1 will be described with reference to the drawings. In the initial state, it is assumed that channel selection data Ds conceptually shown in FIG.
In the television 1, when the power key 31 of the remote control 3 is operated, the remote control 3 outputs an infrared signal Si corresponding to the power key 31, and the light receiving unit 19 receives the infrared signal Si and receives the operation signal So. Output. Next, the key input processing unit 20 outputs the operation signal So, that is, the control signal Sc corresponding to the power key 31 to the control unit 22. In response to this, the control unit 22
A power supply unit (not shown) is controlled to supply power to each unit of the television 1. Subsequently, the channel selection processing unit 11 selects a channel (for example, 220 channels) that was selected at the time of the previous power-off under the control of the control unit 22, and the tuner 12 is selected by the channel selection processing unit 11 220. The broadcast signal Sb of the channel is output to the video / audio processing unit 14.

Next, the video / audio processing unit 14 outputs the video signal Sp1 and the audio signal Ss1 based on the broadcast signal Sb output from the tuner 12 to the video output unit 15 and the audio output unit 17, respectively. Subsequently, the video output unit 15 generates a video signal Sp2 based on the video signal Sp1 and video data stored in a memory (not shown) and outputs the video signal Sp2 to the display unit 16. Next, the optical engine of the display unit 16 projects the projection light that is light-modulated based on the video signal Sp2 onto the screen panel. In addition, the audio output unit 17 outputs the audio signal Ss output from the video / audio processing unit 14.
1 is amplified and an audio signal Ss2 is output to the speaker 18. As a result, as shown in FIG. 2, a video P1 obtained by superimposing a 220-channel television video Pt with a 220-channel channel number Cn is displayed on the display unit 16 and a 220-channel audio is output from the speaker 1.
8 is output.

Next, for example, when channel switching is performed by up channel selection, the channel up key 33a of the remote controller 3 is operated (channel switching operation in the present invention). At this time, the remote controller 3 outputs an infrared signal Si corresponding to the channel up key 33a, and the key input processing unit 20 outputs a control signal Sc corresponding to the channel up key 33a to the control unit 22. In response to this, the control unit 22 executes the up / down channel selection processing 50 shown in FIG. In the up / down channel selection processing 50, the control unit 22 uses the channel selection data Ds stored in the storage unit 13 to select the currently selected channel (220 channels in this example).
The channel having the next highest number (the channel after the next rank in the present invention: 221 channels in this example) is acquired (specified) (step 51).

Next, the control unit 22 determines whether or not a flag (Yes flag) indicating that the acquired channel 221 is skipped is attached based on the channel selection data Ds (step 52). In this case, as shown in FIG. 5, since the Yes flag is attached to the 221 channel, the control unit 22 executes the process of step 51 again to select the next rank channel (in this case, 222 channel). Then, the process of step 52 is executed. Then
The control unit 22 is not marked with a Yes flag, that is, No indicating that it is not skipped.
Steps 51 and 52 are repeated until a channel with the flag is acquired.

In this case, when acquiring the 224 channel shown in FIG. 5, the control unit 22 determines that the Yes flag is not attached to the 224 channel (the No flag is attached) in step 52 described above. Then, the channel selection processing unit 11 selects the acquired 224 channels (step 53). That is, the control unit 22 performs the processing of steps 51 and 52 to skip when the channel after the next rank of the channel selected immediately before the operation of the channel up key 33a corresponds to the channel excluded channel. The channel selection processing unit 11 executes channel selection. Next, the tuner 12 extracts the 224 channel broadcast signal Sb and outputs it to the video / audio processing unit 14, and the video / audio processing unit 14 sends the video signal Sp 1 and the audio signal Ss 1 to the video output unit 15 and the audio output unit 17. Output each.

Subsequently, the video output unit 15 generates the video signal Sp2 based on the video signal Sp1 and the video data stored in the memory outside the figure, under the control of the control unit 22. In this case, the control unit 22 adds the 224 channel channel number C to the 224 channel TV image Pt.
n (hereinafter, the channel number Cn of the selected channel is also referred to as “channel number Cn1”), and the channel number Cn (hereinafter referred to as 221 to 223 channels) of each channel skipped during the skip channel selection (hereinafter referred to as “channel number Cn1”). Channel number Cn of the skipped channel
And a video signal Sp2 to be displayed in an overlapping manner with an icon Ic indicating that each skipped channel is flagged as Yes (set as a channel selection exclusion channel). The video output unit 15 is controlled to generate. As a result, as shown in FIG. 6, a video P2 in which the channel numbers Cn1, Cn2 and the icon Ic (black circles shown in the figure) are superimposed on the 224-channel television video Pt is displayed on the display unit 16 ( Step 54) The audio of 224 channels is output from the speaker 18. In this case, the channel number Cn2 is displayed, so that the user can be surely notified of the channel skipped during the skip channel selection. Further, by displaying the icon Ic, it is possible to reliably notify the user that the channel with the channel number Cn2 adjacent to the icon Ic is set as a channel selection exclusion channel.

Next, the control unit 22 sets the display time t of the channel number Cn2 and the icon Ic to, for example, 2 seconds, starts the timer 21 (step 55), and determines whether or not the control signal Sc is output. (Step 56). At this time, when the control signal Sc is not output, the control unit 22 determines whether or not the timer signal St is output from the timer 21, that is, whether or not the display time t has elapsed (step 57). When the display time t has not elapsed, the determination processing in steps 56 and 57 is repeatedly executed. In addition, the control unit 22
When the display time t has passed without the control signal Sc being output, the timer 21 is stopped (step 58). Subsequently, the control unit 22 controls the video output unit 15 to
The display of the channel number Cn2 and the icon Ic is stopped (step 59), that is, the display is switched to the display of the video P6 in which the channel number Cn1 is superimposed on the television video Pt as shown in FIG. finish.

On the other hand, when it is determined in step 56 that the control signal Sc is output, the control unit 22 determines whether or not the output control signal Sc is the control signal Sc corresponding to the skip setting key 35 (step 60). ). In this case, an operation key other than the skip setting key 35 (
For example, when the control signal Sc corresponding to the volume adjustment key 37) is output, the control unit 22
After executing processing (for example, volume adjustment processing) corresponding to the control signal Sc (operation key) (step 61), the processing of steps 58 and 59 described above is executed, and this up / down tuning processing 50 Exit.

Here, in the television 1, it is possible to perform channel switching to a channel selection exclusion channel skipped at the time of up / down channel selection with an easy operation. Further, in the television 1, it is possible to change the setting of the channel set as the channel selection exclusion channel to the channel selection target channel (cancel the channel selection exclusion channel) with an easy operation. In particular,
In a state where the above channel number Cn2 is displayed, that is, in a state where the control unit 22 is executing the processing of steps 56 and 57 in the up / down channel selection processing 50, the skip setting key 35 of the remote controller 3 is operated. At this time, the control unit 22 determines that the control signal Sc is output in step 56 of the up / down channel selection processing 50, and the control signal Sc corresponds to the skip setting key 35 in step 60. It is discriminated that it is Sc, and the skip setting / cancellation processing 70 shown in FIG. 4 is executed (step 62).

In the skip setting / releasing process 70, the control unit 22 controls the video output unit 15 to display the cursor Cu on the right side of the channel number Cn1 as in the video P3 shown in FIG. 7 (step 71). Next, the control unit 22 determines whether or not the control signal Sc is output (step 72). In this case, when the control signal Sc is not output, the control unit 22 repeatedly executes the determination process in step 72. On the other hand, for example, when switching to the 223 channel among the skipped channel selection exclusion channels (221 to 223 channels), the downward cursor key 34b is operated only once. At this time, the control unit 22 determines that the control signal Sc is output in step 72 described above, and then determines whether the control signal Sc is the control signal Sc corresponding to the cursor key 34a or the cursor key 34b. It is determined whether or not (step 73).

In this case, since the control signal Sc corresponding to the cursor key 34b is output by the operation of the cursor key 34b, the control unit 22 controls the video output unit 15 to move the cursor Cu to the right of the channel number Cn2. Move by minutes. As a result, “22
3 "channel number Cn2 is selected. Next, the control unit 22 controls the channel selection processing unit 11 to select the selected 223 channel. As a result, a 223-channel television image Pt is displayed on the display unit 16 instead of the 224-channel television image Pt, as in the image P4 shown in FIG. 8 (step 74). Subsequently, the control unit 22 executes the process of step 72 described above (determination process for determining whether or not the control signal Sc is output).

On the other hand, for example, when the setting of the selected 223 channel is changed from the channel selection exclusion channel to the channel selection target channel, the cursor Cu is displayed on the right side of the channel number Cn2 of “223” as in the video P4 shown in FIG. In the state where the channel number Cn2 is selected, the right cursor key 34d is operated only once (setting operation in the present invention). At this time, the control unit 22 determines that the control signal Sc is output in step 72 described above, and then executes the process of step 73 described above. In this case, since the control signal Sc is not the control signal Sc corresponding to the cursor keys 34a and 34b, the control unit 22 determines whether or not the control signal Sc is the control signal Sc corresponding to the cursor key 34c or the cursor key 34d. Is determined (step 75).

In this case, since the control signal Sc corresponding to the cursor key 34d is output by the operation of the cursor key 34d, the control unit 22 rewrites the channel selection data Ds stored in the storage unit 13 (step 76). Change the setting of channel 223 from the channel to be excluded to the channel to be selected. Specifically, the control unit 22 replaces the “Yes” flag (see FIG. 5) assigned to the 223 channel with the “No” flag. Next, the control unit 22 controls the video output unit 15 to display “22” as shown in the video P5 in FIG.
The display of the icon Ic on the left side of the channel number Cn2 of “3” is stopped. In this case, by stopping the display of the icon Ic, it is possible to notify the user that the setting of the 223 channel has been changed from the channel selection exclusion channel to the channel selection target channel. Subsequently, the control unit 22 executes the process of step 72 described above (determination process for determining whether or not the control signal Sc is output).

Here, for example, when the 223 channel that has been changed to the channel selection target channel is set again as the channel selection exclusion channel, the cursor Cu is displayed on the right side of the channel number Cn2 of “223” (the channel number Cn2 is selected). In the state, the right cursor key 34d is operated once again (resetting operation in the present invention). At this time, the control unit 22 re-sets the channel 223 from the channel to be selected to the channel to be excluded from the channel selection by executing the processes of steps 73, 75, and 76 as described above. Next, the control unit 22 controls the video output unit 15 to display the icon Ic on the left side of the channel number Cn2 of “223” as in the video P4 shown in FIG. Subsequently, the control unit 22 executes the process of step 72 described above (determination process for determining whether or not the control signal Sc is output).

On the other hand, when the channel switching to the channel selection exclusion channel and the setting change from the channel selection exclusion channel to the channel selection target channel are finished, the skip setting key 35 of the remote controller 3 is operated again. At this time, the control unit 22 executes Steps 77, 73, and 75, and then executes Step 77. The control signal Sc output from the key input processing unit 20 corresponds to the skip setting key 35. It is determined that the signal Sc, and skip setting / cancellation processing 7
Exit 0. Next, the control unit 22 performs step 5 of the up / down channel selection processing 50 described above.
After executing the processing of 8,59, the up / down channel selection processing 50 is terminated.

Thus, according to the television 1, the control unit 22 causes the channel selection processing unit 11 to execute skip channel selection when performing up / down channel selection, and the channel number of the skipped channel is displayed on the display unit 16. By displaying, it is possible to reliably notify the user of the channel skipped during the skip channel selection. For this reason, users can, for example,
Even when the user forgets which channel is set as a channel to be excluded from channel selection, the set channel can be surely grasped.

Further, according to the television 1, when the channel number Cn2 displayed on the display unit 16 is selected, the control unit 22 sends the channel selection exclusion channel of the selected channel number Cn2 to the channel selection processing unit 11. By selecting the channel, it is possible to switch to the channel of the selected channel number Cn2 only by performing a simple operation of selecting the channel number Cn2 on the screen on which the TV video Pt is displayed. Therefore, the channel can be switched in a short time without causing an input error as compared with the method of inputting the channel number of the channel selection exclusion channel using the numeric keys.

Further, according to the television 1, when the channel number Cn2 displayed on the display unit 16 is selected and the cursor keys 34c and 34d are operated, the control unit 22 selects the channel of the selected channel number Cn2. By changing the setting to the channel to be selected, the channel number Cn2 is selected on the screen on which the television image Pt is displayed, and the cursor key 3
By simply operating 4c and 34d, the channel of the selected channel number Cn2 can be set and changed to the channel to be selected. For this reason, it is possible to change the setting easily in a short time as compared with the method of switching to the setting screen and resetting the setting screen.

Further, according to the television 1, when the channel number Cn2 of the channel to be selected after the setting change displayed on the display unit 16 is selected and the cursor keys 34c and 34d are operated, the control unit 22 By resetting the selected channel number Cn2 as a channel to be excluded from channel selection, the channel number Cn2 is selected on the screen on which the television image Pt is displayed and the cursor keys 34c and 34d are operated. The channel whose setting has been changed to the station target channel can be set again as the channel selection exclusion channel. Therefore, for example, even if the channel selection exclusion channel is erroneously changed to the channel selection target channel, it can be easily restored to the original setting.

In addition, this invention is not limited to said structure and method. For example, when the cursor Cu is moved and the channel number Cn2 is selected, the channel selection processor 11 selects the channel, that is, the cursor Cu is moved regardless of whether or not the channel selection target channel is changed. Although the configuration example in which the channel is switched only by the above is described above, a configuration in which the channel is switched by another method may be employed. Specifically, after changing the setting from the channel selection exclusion channel to the channel selection target channel on the screen, the cursor Cu is moved to the channel selection target channel whose setting has been changed and selected, and in this state, for example, the enter key 36 is operated ( It is possible to adopt a configuration in which channel selection is performed for a channel to be selected when a channel selection operation in the present invention is performed. According to this configuration, for example, when changing the setting of a plurality of channel exclusion channels displayed on the screen to the channel to be selected, the channel cannot be switched only by moving the cursor Cu. The channel selection exclusion channel can be set and changed to the channel to be selected while watching the TV image Pt of the channel selected by the channel (224 channel in the above example). Also, according to this configuration, only the channel whose setting has been changed to the channel to be selected can be selected (channel switching), so that the channel selected by the above operation can be selected for the next up / down selection. It is possible to select a channel without jumping even at the time of station.

In addition, the configuration example in which the channel selection exclusion channel and the channel selection target channel are identified by the display and non-display of the icon Ic has been described above, but the color of the channel number Cn2 instead of the icon Ic or together with the display of the icon Ic. It is also possible to adopt a configuration in which the channel thickness is different between the channel selection exclusion channel and the channel selection target channel so that the channel identification target channel can be identified.

Further, the example in which the present invention is applied to the projection television 1 including the display unit 16 having the optical engine and the screen panel has been described above. The present invention can also be applied. In addition, various channel selection devices such as a BS tuner, a CS tuner, an analog broadcast tuner, and a cable broadcast tuner that do not include the video output unit 15, the display unit 16, the audio output unit 17, and the speaker 18, and these The present invention can also be applied to AV equipment such as VTRs, DVD recorders, and hard disk recorders equipped with the above channel selection apparatus.
