The selection correspondence information storage means corresponds to first selection correspondence information in which the selection operation key and the channel of the television broadcast are associated, and the selection operation key and the video output device. Second selection correspondence information attached to the remote control means, the selection correspondence information used for the selection processing by the selection processing means, the first selection correspondence information and the second selection A switching key for switching to either one of the correspondence information is provided, and the selection correspondence information used for the selection processing by the selection processing means is changed from the first selection correspondence information to the first by the operation of the switching key. When switched to the second selection correspondence information, the second selection correspondence information is displayed.
In the television receiver configured as described above, the second selection correspondence information displayed by operating the switching key is referred to, and the selection operation key corresponding to the desired video output device is operated. By doing so, it is possible to easily select the desired video output device. Therefore, the number of operations for selecting a plurality of video output devices connected to the television receiver is reduced.

Further, it is desirable that the external video input means can acquire identification information for identifying the video output device.

A key 74 (an example of a switching key) and an automatic registration key 75 are provided. In addition to the various keys shown in FIG. 2, the remote controller 7 is provided with a volume adjustment key or the like provided on a remote control of a general television receiver, but the description thereof is omitted here.
In response to various key operations, the remote controller 7 transmits input operation signals corresponding to the keys to the remote controller I / F 8 by wireless transmission such as infrared transmission.

The remote controller I / F 8 acquires the input operation information transmitted from the remote controller 7 and outputs the input operation information to the control circuit 11. In the television receiver X, various processes corresponding to the input operation information are executed by the MPU 11a.
Specifically, when the channel selection key 72 is pressed on the remote controller 7 and the input operation information corresponding to the channel selection key 72 is input to the remote control I / F 8, the MPU 11a Based on the transmitted input operation information, a display content (output content) to be displayed (output) on the monitor screen 6 is selected. At this time, the display content is determined based on selection correspondence information 31 and 32 (to be described later) stored in advance in the RAM 11c.

Here, the selection correspondence information 31 and 32 stored in the RAM 11c will be described with reference to FIG.
As shown in FIGS. 3A and 3B, the RAM 11c has two different selection correspondence information 31 (first information) in which the channel selection key 72 and the display contents to be displayed on the monitor screen 6 are associated with each other. ) And selection correspondence information 32 (an example of second selection correspondence information) are stored. That is, the RAM 11c is an example of a selection correspondence information storage unit.
For example, in the selection correspondence information 31, as shown in FIG. 3A, the channel selection key 72a is associated with a channel 1 (1CH) of television broadcasting, whereas the selection correspondence information 32 As shown in FIG. 3B, the channel selection key 72a is associated with the channel 2 (2CH) of television broadcasting.
The selection correspondence information 31 is set by channel setting or the like in the initial setting of the television receiver X, and the selection correspondence information 32 is a preference registration / operation process (described later in the flowchart of FIG. 4) executed by the MPU 11a. Reference). Here, the MPU 11a when executing such setting processing corresponds to the selection correspondence information setting means.

In the television receiver X configured as described above, when the preference key 74 provided on the remote controller 7 is pressed, the selection correspondence information used in the control circuit 11 is changed to the selection correspondence information 31 and It is switched to either one of the selection correspondence information 32.
Hereinafter, an example of a procedure of preference registration / operation processing executed by the MPU 11a in the television receiver X will be described with reference to FIG. In the figure, S1, S2,... Represent processing procedure (step) numbers.
First, in step S1, the MPU 11a determines whether or not the favorite key 74 of the remote controller 7 has been pressed. Specifically, it is determined whether or not input operation information corresponding to the preference key 74 is input to the remote control I / F 8 by pressing the preference key 74 of the remote control 7.

  If it is not determined that the preference key 74 has not been pressed (No side of S1), the process proceeds to step S11. In this case, when the channel selection key 72 of the remote controller 7 is operated (Yes side of S11), the display contents to be displayed on the monitor screen 6 based on the operated channel selection key 72 and the selection correspondence information 31. Is selected (S12). For example, when the channel selection key 72a of the remote controller 7 is pressed, the channel 1 (1CH) of the television broadcast corresponding to the channel selection key 72a based on the selection correspondence information 31 (see FIG. 3A). Is selected and output to the monitor screen 6. If the channel selection key 72 of the remote controller 7 is not operated (No in S11), the process returns to the step S1.

On the other hand, if it is determined in step S1 that the preference key 74 has been pressed (Yes in S1), the process proceeds to step S2.
In step S2, the selection correspondence information 32 stored in the RAM 11c is output to the monitor screen 6 by the MPU 11a, so that the selection correspondence information 32 is displayed on the monitor screen 6 as shown in FIG. 6 is displayed. Here, the MPU 11a when executing the display processing of the selection correspondence information 32 corresponds to the selection correspondence information display means. The user can easily know the contents of the selection correspondence information 32 by this display. At this time, on the monitor screen 6, as shown in FIG. 5A, a display for prompting the operation of the enter key 73a provided on the operation key 73 of the remote controller 7 or the channel operation key 72 is performed.

Next, in step S3, the MPU 11a determines whether or not the decision key 73a has been pressed. Specifically, it is determined whether or not input operation information corresponding to the determination key 73a is input to the remote control I / F 8 by pressing the determination key 73a of the remote control 7.
Here, when it is determined that the determination key 73a is pressed (Yes side of S3), the process proceeds to Step S4, and when it is determined that the determination key 73a is not pressed (No side of S3), The process proceeds to step S31.

First, the case where it is determined that the determination key 73a has not been pressed (No side in S3) will be described.
In this case, when the channel selection key 72 of the remote controller 7 is operated (Yes side of S31), the display contents to be displayed on the monitor screen 6 based on the operated channel selection key 72 and the selection correspondence information 32. Is selected by the MPU 11a (S32). For example, when the channel selection key 72a of the remote controller 7 is pressed, the channel 2 (2CH) of the television broadcast corresponding to the channel selection key 72a based on the selection correspondence information 32 (see FIG. 3B). Is selected and output to the monitor screen 6. If the channel selection key 72 of the remote controller 7 is not operated (No side of S31), the process returns to step S3.
That is, in the television receiver X, when the preference key 74 is operated, the MPU 11a stores the selection correspondence information to be referred to when the channel selection key 72 is operated, stored in the RAM 11c. Switching to either the selection correspondence information 31 or the selection correspondence information 32 is performed. Here, a display content selection process for displaying power on the monitor screen 6 based on the channel selection key 72 operated on the remote controller 7 and the selection correspondence information 31 or the selection correspondence information 32 stored in the RAM 11c (see FIG. The MPU 11a when executing S12, S32) corresponds to the selection processing means.

Hereinafter, the case where it is determined in step S3 that the determination key 73a has been pressed (Yes side of S3) will be described.
In this case, in the subsequent step S4, the MPU 11a displays a display for prompting the operation of either the channel selection key 72 or the automatic registration key 75 together with the selection correspondence information 32 stored in the RAM 11c. The data is output and displayed on the monitor screen 6 (see FIG. 5B).
In the subsequent step S5, it is determined by the MPU 11a whether or not the channel selection key 72 has been selected. Specifically, it is determined whether or not input operation information corresponding to the channel selection key 72 is input to the remote control I / F 8 by pressing the channel selection key 72 of the remote control 7.
If it is determined that the channel selection key 72 has been pressed (Yes in S5), the process proceeds to step S6, and if it is determined that the channel selection key 72 has not been pressed ( On the No side of S5), the process proceeds to step S51.

First, the case where it is determined in step S5 that the channel selection key 72 has been pressed (Yes in S5) will be described.
In this case, in the subsequent step S61, it is determined by the MPU 11a whether or not the television tuner 1 is selected as the display content to be displayed on the monitor screen 6.
If it is determined that the TV tuner 1 is selected (Yes side in S6), the process proceeds to step S61. In the step S61, the display content displayed on the monitor screen 6 from the television tuner 1 by the MPU 11a, that is, any channel of the television broadcast is set to the channel selection key 72 pressed in the step S5. The corresponding display content is registered in the selection correspondence information 32. For example, when the channel 2 of the television broadcast is displayed on the monitor screen 6, when the channel selection key 72a is pressed in the step S5, the display content corresponding to the channel selection key 72a is displayed on the television screen. Registered in broadcast channel 2 (2CH).

On the other hand, when it is determined that the TV tuner 1 is not selected (No side in S6), the process proceeds to step S7. In step S7, it is determined by the MPU 11a whether or not the external input I / F 2a is selected as the display content to be displayed on the monitor screen 6.
If it is determined that the external input I / F 2a has been selected (Yes in S7), the process proceeds to step S71. In the step S71, the display contents displayed on the monitor screen 6 by the MPU 11a, that is, the external input I / F 2a is selected as the display contents corresponding to the channel selection key 72 pressed in the step S5. Information 32 is registered. For example, when the video input from the external input I / F 2a is displayed on the monitor screen 6, when the channel selection key 72b is pressed in the step S5, the display corresponding to the channel selection key 72b is displayed. The external input I / F 2a is registered as the content (see FIG. 5C).

Furthermore, when it is determined in step S7 that the external input I / F 2a is not selected (No side in S7), the process proceeds to step S8. In step S8, the MPU 11a determines whether or not the IEEE 1394 I / F 2b is selected as the display content to be displayed on the monitor screen 6.
If it is determined that the IEEE 1394 I / F 2b is selected (Yes in S8), the process proceeds to step S81. In step S81, the display content displayed on the monitor screen 6 by the MPU 11a, that is, the video output device connected to the IEEE 1394 I / F 2b is displayed corresponding to the channel selection key 72 pressed in step S5. The contents are registered in the selection correspondence information 32 as contents. For example, when the video input from the HDD 22 connected to the IEEE1394 I / F 2b is displayed on the monitor screen 6, when the channel selection key 72c is pressed in the step S5, the channel selection key 72c The HDD 22 is registered as the display content corresponding to (see FIG. 5D).
At this time, since the IEEE 1394 I / F 2b can acquire the identification information of the video output device such as the HDD 22 or the DVD 23, in the step S81, the MPU 11a and the IEEE 1394 I / F 2b together with the video output device. The identification information of the video output device acquired by the above is registered in the selection correspondence information 32.
If it is determined in step S8 that the IEEE1394 I / F 2b is not selected (No in S8), the process returns to step S1.

Next, the case where it is determined in step S5 that the channel selection key 72 has not been pressed (No in S5) will be described.
In this case, in the subsequent step S51, the MPU 11a determines whether or not the automatic registration key 75 has been pressed. Specifically, it is determined whether or not input operation information corresponding to the automatic registration key 75 is input to the remote control I / F 8 by pressing the automatic registration key 75 of the remote control 7.
If it is determined that the automatic registration key 75 has been pressed (Yes in S51), the process proceeds to step S52, and if it is determined that the automatic registration key 75 has not been pressed (S51). On the No side), the process returns to step S5.

In step S52 and subsequent steps, the MPU 11a automatically associates the video output device connected to the television receiver X or connected in the past with the channel selection key 72 and stores the selection stored in the RAM 11c. Processing for registering in the correspondence information 32 is executed. Here, the MPU 11a when executing the automatic registration processing corresponds to the automatic registration means.
First, in the step S52, the MPU 11a determines whether or not the channel selection key 72 for which the corresponding display content is not registered exists in the selection correspondence information 32.
Here, when it is not determined in the selection correspondence information 32 that the channel selection key 72 for which the corresponding display content is not registered exists (No side of S52), the process returns to the step S5. If it is determined that it exists (Yes in S52), the process proceeds to step S53. In the present embodiment, as shown in FIG. 5B, since the display contents of the channel selection keys 72b to 72e are not registered, the process proceeds to step s53.

In step S53, the MPU 11a determines whether or not a video output device is connected to the external input I / F 2a or the IEEE 1394 I / F 2b.
If it is determined that the video output device is connected to the external input I / F 2a or the IEEE 1394 I / F 2b (Yes in S53), the process proceeds to step S54, and it is determined that the video output device is not connected. If so (No in S53), the process proceeds to step S56. In the present embodiment, since the D-VHS 21 is connected to the external input I / F 2a and the HDD 22 and DVD 23 are connected to the IEEE 1394 I / F 2b, the process proceeds to step S54.

In step S54, the MPU 11a automatically registers the external input I / F 2a, the HDD 22, and the DVD 23 in the channel selection key 72 in which the corresponding display content is not registered in the selection correspondence information 32. .
Specifically, as shown in FIG. 5E, the display contents corresponding to the channel selection key 72b in the selection correspondence information 32 are the display contents corresponding to the external input I / F 2a and the channel selection key 72c. The DVD 23 is registered as display contents corresponding to the HDD 22 and the channel selection key 72d. At this time, as described above, since the IEEE 1394 I / F 2b can acquire the identification information of the HDD 22 and the DVD 23, the identification information is also registered in the selection correspondence information 32.

Thereafter, when the registration of the video output device connected to the television receiver X in the selection correspondence information 32 is completed in the step S54, the corresponding display content is again displayed in the selection correspondence information 32 in the subsequent step S55. It is determined by the MPU 11a whether or not there is the channel selection key 72 that is not registered.
If it is determined in the selection correspondence information 32 that the channel selection key 72 for which the corresponding display content is not registered does not exist (No side of S54), the process returns to the step S5. If it is determined that it exists (Yes in S54), the process proceeds to step S56. Here, as shown in FIG. 5E, since there is a channel selection key 72e whose display contents are not registered, the process proceeds to step S56.

Next, in step S56, it is determined by the MPU 11a whether or not there is a video output device connected to the television receiver X in the past.
Here, if it is determined that there is a video output device connected in the past (Yes side of S56), the process proceeds to step S57, and if it is determined that it does not exist (No side of S56). The process returns to step S5. In the present embodiment, since the D-Tuner 24 has been connected to the IEEE 1394 I / F 2b of the television receiver X in the past, the process proceeds to step S57.

In step S57, the MPU 11a automatically registers the D-Tuner 24, which has been connected in the past, in the channel selection key 72 in which the corresponding display content is not registered in the selection correspondence information 32. The process returns to step S1.
Specifically, as shown in FIG. 5 (f), the D-Tuner 24 is registered as display content corresponding to the channel selection key 72 e in the selection correspondence information 32. At this time, as described above, the identification information of the D-Tuner 24 acquired in the past by the IEEE 1394 I / F 2b is stored and held in the RAM 11c. Therefore, the identification information is read from the RAM 11c and stored in the RAM 11c. It is registered in the selection correspondence information 32.

As described above, in the preference registration / operation process (see the flowchart of FIG. 4), the external input I / F 2a, the HDD 22, the DVD 23, the D-Tuner 24 and the channel selection key 72 are associated with each other. If it is registered in the selection correspondence information 32 (corresponding to the second selection correspondence information) of the RAM 11c, when the preference key 74 is subsequently pressed in the television receiver X, FIG. As shown, the selection correspondence information 32 in which the external input I / F 2 a, the HDD 22, the DVD 23, and the D-Tuner 24 are assigned to the channel selection key 72 is displayed on the monitor screen 6. At this time, since the identification information is stored for the HDD 22, the DVD 23, and the D-Tuner 24 connected to the IEEE 1394 I / F or connected in the past, as shown in FIG. It is desirable to display the selection correspondence information 32 including the model number (BB, CC, DD) which is a part of the identification information.
