  When the operation screen is output and the controller for operating the operation screen is not operated for a specified period of time, the operation screen is automatically deleted or the power is turned off. There is no operation time-out process to enter the mode. For example, in the case of a digital broadcast receiving device, if the operation setting function menu screen of the device is displayed and the no-operation state continues for a predetermined time, the menu screen is automatically deleted and the program viewing screen is not returned. Operation timeout processing may be performed.

(Example 1)
Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. The digital broadcast receiving apparatus according to the first embodiment displays an operation screen (GUI) that operates in conjunction with both the key operation of a key provided in the remote controller and the three-dimensional operation of moving the remote controller in three dimensions. The user can easily input an operation instruction to the digital broadcast receiving apparatus such as function setting and channel switching by visually operating the remote controller with a key operation and three-dimensional operation while viewing the operation screen.

FIG. 1 is a functional block diagram of the digital broadcast receiving apparatus according to the first embodiment. Note that the reference numerals in parentheses of the effective area determination unit 1100, the no-operation counting unit, the application unit, and the timeout time determination unit displayed in broken lines in FIG. 1 represent components related to the digital broadcast receiving apparatus of the second or third embodiment. This is not related to the present embodiment.

The remote control signal processing unit 100 includes a remote control signal light receiving unit (not shown), acquires a key code and pointer coordinates from a remote control signal received by the light receiving unit, and a user interface unit 200.
To pass. The key code is a command system determined in accordance with an instruction that can be input to the digital broadcast receiving apparatus by a remote control operation, such as a channel switching instruction or an electronic program guide display instruction, and is held by the remote control signal processing unit 100.
The remote control signal processing unit 100 acquires the current pointer coordinates from the user interface unit 200, calculates new pointer coordinates from the three-dimensional operation signal (acceleration signal, tilt signal) acquired from the remote control signal, and passes them to the user interface unit 200. . Details of the remote control signal processing unit 100 will be described later. In this embodiment, the remote controller corresponds to the controller of the present invention.

The user interface unit 200 controls the application unit 400 and the broadcast receiving unit 700 based on the key code input from the remote control signal processing unit 100. The user interface unit 200 passes the key code from the remote control signal processing unit 100 to the application unit 400 and the no-operation counting unit 600. The user interface unit 200 passes the new pointer coordinates from the remote control signal processing unit 100 to the pointer creation unit 300, the application unit 400, and the no-operation counting unit 600. The user interface unit 200 acquires remote control operation type information (information indicating whether the operation is a key operation or a three-dimensional operation) from the remote control signal processing unit 100, and passes the information to the application unit 400. The process in which the remote control signal processing unit 100 determines the remote control operation type will be described later. The user interface unit 200 passes the current pointer coordinates acquired from the remote control signal processing unit 100 to the remote control signal processing unit 100.

  The pointer creation unit 300 creates a pointer image based on the pointer coordinates acquired from the user interface unit 200, and passes the pointer image to the GUI superimposing unit 900.

The application unit 400 creates an operation screen of an application corresponding to the key code acquired from the user interface unit 200 and passes it to the GUI superimposing unit 900. The application provides a function of inputting operation instructions such as setting of the digital broadcast receiving apparatus main body, video input switching, three-digit channel number input, and electronic program guide display to the digital broadcast receiving apparatus. The application unit 400 controls the operation screen of the application according to the key code and pointer coordinates from the user interface unit 200, so that the operation screen operates in conjunction with the user's remote control operation. The operation screen includes, for example, a window, a list of options, a focus frame, and the like. Control of the operation screen includes, for example, movement of the focus frame, screen transition, item selection, and the like. The application unit 400 acquires remote control operation type information from the user interface unit 200. The application unit 400 requests the timeout time determination unit 500 to determine the no-operation timeout time. The application unit 400 acquires the no-operation timeout period determined by the timeout period determination unit 500, and requests the no-operation count unit 600 to count the no-operation period in order to perform the no-operation timeout process with the no-operation timeout period. .
When the application unit 400 receives a notification from the no-operation counting unit 600 that the no-operation period has reached the no-operation timeout period, the application unit 400 executes no-operation timeout processing. The no-operation time-out process refers to the GUI superimposing unit 900 on the operation screen when the duration of the no-operation state of the remote control after the last remote control operation for operating the operation screen reaches a predetermined threshold. This is a process of automatically stopping the output and deleting the operation screen from the monitor. Hereinafter, the threshold value for the duration of the no-operation state is referred to as “no-operation timeout time”. Further, the duration of the non-operation state of the remote controller since the last remote control operation for operating the operation screen is referred to as “non-operation period”. The no-operation period is a period in which a key code or pointer coordinates from the user interface unit 200 is not passed.
In the present embodiment, the application unit 400 corresponds to the output unit of the present invention.

Upon receiving the no-operation timeout time determination request from the application unit 400, the timeout time determination unit 500 refers to the timeout time information for each application, determines the no-operation timeout time, and passes it to the application unit 400. Here, the time-out information for each application is a table that defines the initial value of the no-operation time-out time and the premium rate during three-dimensional operation for each application. The premium rate at the time of three-dimensional operation is a ratio for increasing and correcting the no-operation timeout time when the remote control operation type is a three-dimensional operation. Details will be described later. The timeout time information for each application is held by the timeout time determination unit 500. Details of the processing of the timeout time determination unit 500 will be described later. In this embodiment, the timeout time determination unit 500 corresponds to the setting unit of the present invention.

  When receiving the no-operation count request from the application unit 400, the no-operation counting unit 600 counts the no-operation period. When the no-operation period reaches the no-operation timeout period designated by the application unit 400, the no-operation counting unit 600 notifies the application unit 400 to that effect. Details of the no-operation counting unit 600 will be described later.

The broadcast receiving unit 700 receives program data multiplexed by the MPEG2-TS method from a broadcast wave, and separates it into video, audio, and data. Here, the data is data for data broadcasting, captions, PSI / SI (Program Specific Information / Service Information), and the like. The compressed encoded video and audio separated by the broadcast receiving unit 700 are decompressed and decoded by the video decoding unit 800 and the audio decoding unit (not shown), respectively, and output to a monitor and a speaker (not shown), respectively. Here, PSI / SI is information for selecting an arbitrary channel or an arbitrary program, and includes information such as a channel number and a program title.

  The video decoding unit 800 decompresses and decodes the compressed and encoded video separated by the broadcast receiving unit 700 and passes it to the GUI superimposing unit 900.

The GUI superimposing unit 900 superimposes the pointer screen acquired from the pointer creating unit 300 and the operation screen acquired from the application unit 400 on the program video input from the video decoding unit 800 and outputs the superimposed video to the monitor.
At this time, the program video may be erased to display only the operation screen, or the luminance of the program video may be reduced and the operation screen may be displayed as an overlay thereon.

The time management unit 1000 manages the current time based on the time information included in the PSI / SI information separated by the broadcast receiving unit 700. The time management unit 1000 monitors the passage of time after the no-operation counting unit 600 starts counting the no-operation period, and when the period specified by the no-operation counting unit 600 has elapsed, Notify that the specified period has passed.

FIG. 13A shows an example of a screen displayed on the monitor of the digital broadcast receiving apparatus when the operation screen is output. In FIG. 13A, a screen 90 represents the entire screen that the GUI superimposing unit 900 outputs to the monitor. An image 80 represents a program video output from the video decoding unit 800. The menu 41 and the video setting window 42 represent operation screens created by the application unit 400. The example shown in FIG. 13 (A) is an example of an operation screen that is output when the function setting menu of the apparatus main body is called and video setting is selected from the function setting menu. A pointer 30 represents a pointer image created by the pointer creation unit 300. The example shown in FIG. 13A is an example of an operation screen that is output when the brightness adjustment of the video setting is performed by a three-dimensional operation. As shown in FIG. 13 (A), the operation screens 41 and 42 of the menu application are displayed as an overlay on the program video 80. When the duration of the no-operation state of the remote control reaches the no-operation timeout time, the menu 41, the video setting window 42 and the pointer 30 are automatically deleted by the no-operation timeout process, and only the program video 80 is displayed on the screen 90. It becomes a state.

  FIG. 2 is a functional block diagram of remote control signal processing unit 100.

The operation type determination unit 101 determines whether the remote control operation type is a key operation or a three-dimensional operation according to the format of the received remote control signal. Here, the format of the remote control signal is
It is a format for storing information on a key press state or a format for storing information on a sensor state.
The key pressing state information includes key identification information for specifying the pressed key, information indicating whether the key is pressed or released, information indicating whether the key is pressed or not, and the like.
The sensor state information includes an acceleration sensor detection value and an inclination sensor detection value. The acceleration sensor and the tilt sensor are sensors that detect the acceleration of the remote control and the tilt of the remote control during a three-dimensional operation by the user, and are built in the remote control. Details of the operation type determination process by the operation type determination unit 101 will be described later.
If the remote control operation type is determined to be a key operation, the operation type determination unit 101 passes the key pressing state information to the key processing unit 102, and if the remote control operation type is determined to be a three-dimensional operation, the operation state information Is transferred to the pointer processing unit 103.

Upon receiving the key press state information from the operation type determination unit 101, the key processing unit 102 converts the information into a key code and passes it to the user interface unit 200. The key processing unit 102 holds a table for converting key identification information in the key pressing state information into key codes. The key processing unit 102 holds a rule for adding key press state information (information such as the presence or absence of long press) other than the key identification information to the key code. As an example of the additional rule, there is a case where information on the presence or absence of long press is given to the most significant bit of the key code.

When the pointer processing unit 103 receives the sensor state information from the operation type determination unit 101, the pointer processing unit 103 converts the information into pointer coordinates and passes it to the user interface unit 200. The pointer processing unit 103 calculates a difference coordinate from the acceleration sensor detection value and the tilt sensor detection value (see FIG. 3). The acceleration sensor detection value represents the pointer movement amount, and the tilt sensor detection value represents the pointer movement direction. Figure 3
In the case of the acceleration sensor detection value a and the inclination sensor detection value θ, the difference coordinate is (acosθ
, Asinθ). The pointer processing unit 103 calculates new pointer coordinates based on the difference coordinates and the current pointer coordinates acquired from the user interface unit 200.

A process in which the timeout time determining unit 500 determines the no-operation timeout time using the application-specific timeout time information will be described. FIG. 4 shows a process flow of the timeout time determination unit 500, and FIG. 5 shows an example of application-specific timeout time information.
Upon receiving the no-operation timeout time determination request from the application unit 400, the timeout time determination unit 500 confirms the application identification (S501). The application identification is information for identifying the various applications described above, and the application unit 400 passes the information to the timeout time determination unit 500 together with a request for determining the no-operation timeout time. In this example,
A case where the application identification is a menu application will be described as an example.
The timeout time determination unit 500 acquires the initial value of the no-operation timeout time for the application confirmed in step S501 from the timeout information for each application, and sets this value as the no-operation timeout time (S502). In the example of FIG. 5, since 1 minute is set as the no-operation timeout time for the menu application, the no-operation timeout time is set to 1 minute in step S502.
Next, the timeout time determination unit 500 acquires remote control operation type information from the application unit 400 (S503).
If the operation type is a three-dimensional operation (Y in S504), the timeout time determination unit 500 obtains an additional rate of the no-operation timeout time for this application from the timeout time information for each application. Then, the no-operation timeout period is corrected to increase according to this premium rate (S505), and the no-operation timeout period determination process ends. In the example of FIG. 5, since the premium rate of the no-operation timeout time for the menu application is 10%, the no-operation timeout time of the menu application in the case of three-dimensional operation is 1 minute 6 seconds.
If the operation type is not a three-dimensional operation (N in S504), timeout time determination unit 500 ends the no-operation timeout time determination process. In the example of FIG. 5, the no-operation timeout time for the menu application in the case of key operation is 1 minute.
As shown in FIG. 5, in this embodiment, the rate of increase in the no-operation timeout time is varied for each application. For example, when the application is an input switching list, the no-operation timeout period is 30%, so the no-operation timeout period for a three-dimensional operation is 1 minute 18 seconds. Similarly, the non-operation timeout time extra rate when the application is a three-digit number input is 50%, so the non-operation timeout time for three-dimensional operation is 1 minute 30 seconds.

A process in which the no-operation counting unit 600 counts the no-operation period based on the designated no-operation timeout time will be described. FIG. 6 shows a processing flow of the no-operation counting unit 600.
When the no-operation count unit 600 receives the no-operation count request from the application unit 400, the no-operation count unit 600 sets the no-operation timeout time designated by the application unit 400 as a count value (S601). The non-operation counting unit 600 waits for notification that one second has elapsed from the time management unit 1000 (S602), and if there is a notification (Y in S602), subtracts the count value by one second (S603). Next, the no-operation counting unit 600 confirms the count value (S604), and if the count value is 0 seconds (Y in S604), notifies the application unit 400 that the no-operation period has reached the no-operation timeout time. (S606), and the non-operation period counting process ends.
If the count value is not 0 seconds (N in S604), the no-operation counting unit 600 checks whether a three-dimensional operation or a key operation has occurred (passed from the user interface unit 200) (S605).
The no-operation counting unit 600 resets the no-operation period count if a three-dimensional operation or key operation occurs (Y in S605) (sets the no-operation timeout period specified by the application unit 400 to the count value). (S601).
If no three-dimensional operation or key operation has occurred (N in S605),
Continue counting the no-operation period (wait for notification from the time management unit 1000 that 1 second has elapsed)
(S602).
In this embodiment, the no-operation counting unit 600 corresponds to the control unit of the present invention.

As described above, according to the present embodiment, the no-operation timeout time is set longer in the three-dimensional operation than in the key operation. As a result, even if the pointer moves away from the operation screen due to camera shake or looking aside during 3D operation and it is counted as a no-operation period, the menu screen is erased against the user's intention by the no-operation timeout process. Can be suppressed.

Although only the menu application has been described in the present embodiment, the same effect can be obtained with an input switching application, a 3-digit channel number input application, and an electronic program guide application. In that case, as shown in FIG. 5, the rate of increase in the no-operation timeout time during three-dimensional operation is changed for each application. For example, when entering a three-digit channel number, the pointer tends to go out of the operation screen when the user drops his eyes on the television column of a newspaper or magazine to confirm the channel number, and an unintended no-operation period is counted. There is a high possibility. In the example of FIG. 5, in view of this point, in the case of a three-digit channel number input application, the premium rate of the no-operation timeout time at the time of three-dimensional operation is set larger than that of other applications. In this way, in consideration of the ease of occurrence of an event that the pointer goes out of the operation screen during the three-dimensional operation, an additional rate of the no-operation timeout time during the three-dimensional operation may be set for each application. As a result, when the user inputs an instruction to the digital broadcast receiving device via the operation screen by a three-dimensional operation, it is more certain that the operation screen disappears due to the no-operation timeout process against the user's intention. Can be suppressed.

(Example 2)
In this embodiment, a case will be described in which the count of the no-operation period is changed depending on whether the pointer coordinates are within a predetermined effective area of the operation screen.

The functional block diagram of the digital broadcast receiving apparatus of this embodiment is obtained by adding an effective area determination unit 1100 indicated by a broken line to the functional block diagram of FIG. 1 described in the first embodiment. Other components are the same as those in the first embodiment. However, since the processing content of the non-operation counting unit is different from that of the non-operation counting unit 600 of the first embodiment, the reference numeral is changed to be the non-operation counting unit 601 in this embodiment. The following description will focus on differences from the first embodiment.

When the no-operation counting unit 601 receives the no-operation counting request from the application unit 400, the no-operation counting unit 601 counts the no-operation period. In the first embodiment, the period during which no key code or pointer coordinates from the user interface unit 200 are simply passed is counted as the no-operation period. However, the non-operation period counting method of the present embodiment is different from that of the first embodiment. Details will be described later.
When the pointer coordinates are passed from the user interface unit 200, the operation count unit 601 requests the effective area determination unit 1100 to determine whether the pointer coordinates are within the effective area. Details of the no-operation counting unit 601 will be described later.

Upon receiving an effective area determination request from the no-operation counting unit 601, the effective area determination unit 1100 refers to the application-specific effective area information to determine whether the pointer coordinates are within the effective area, and determines the determination result as the no-operation counting unit. Pass to 601. Here, the effective area is a predetermined area that is not regarded as a no-operation state if the pointer coordinates are within that area during the three-dimensional operation. Application-specific effective area information is a table that stores information about effective areas determined for each application. The layout information (upper left coordinates, width, height) of the operation screen and the margin area that is effective during three-dimensional operation Contains information. The margin area at the time of 3D operation is an area set around the operation screen, and constitutes an effective area at the time of 3D operation together with the area of the operation screen. The effective area information for each application is held by the effective area determination unit 1100. Details of the effective area determination unit 1100 will be described later. In this embodiment, the area obtained by combining the area of the operation screen and the margin area corresponds to the predetermined effective area of the present invention.

FIG. 13B is a diagram for explaining the operation screen, the margin area, and the effective area. FIG.
In FIG. 13B, the same reference numerals and names are used for the same components as those in FIG. A hatched area 110 set around the operation screen (menu 41 and video setting window 42) is a margin area. An area obtained by combining the margin area and the areas of the operation screens 41 and 42 is an effective area. In the example shown in FIG. 13B, the coordinates of the pointer 30 are out of the area of the operation screens 41 and 42, but are in the margin area 110, so the coordinates of the pointer 30 are within the effective area. Therefore, the state shown in FIG. 13B is not regarded as a no-operation state.
That is, the pointer 30 is moved to the operation screens 41 and 42 by a hand shake or a side look during a three-dimensional operation by the user.
Even if it is out of the area, no operation period is not counted.

A process in which the no-operation counting unit 601 counts the no-operation period based on the designated no-operation timeout time will be described. FIG. 7 shows a processing flow of the no-operation counting unit 601. FIG.
In the processing flow of FIG. 6, the processing of step S611 to step S615 and the processing of step S619 are the same as the processing of step S601 to step S605 and the processing of step S606 of FIG. .
If there is a three-dimensional operation or key operation (Y in S615), the no-operation counting unit 601 determines whether it is a three-dimensional operation (S616). If no operation has occurred (N in S615), the process returns to step S612.
When a three-dimensional operation has occurred (Y in S616), the no-operation counting unit 601 acquires a pointer coordinate from the user interface unit 200, and determines whether or not the pointer coordinate is within the effective region. Request to 1100 (S617).
When a key operation has occurred (N in S616), the no-operation counting unit 601 resets the no-operation timeout time designated by the application unit 400 to the count value (S611).
The no-operation counting unit 601 determines whether the pointer coordinates are within the effective region based on the determination result acquired from the effective region determining unit 1100 (S618).
When the pointer coordinates are within the valid area (Y in S618), the no-operation counting unit 601 resets the count of the no-operation period (resets the count value at the no-operation timeout period designated by the application unit 400) (S611 ).
If the pointer coordinates are not within the valid area (N in S618), the no-operation counting unit 601 continues to count the no-operation period (waits for notification from the time management unit 1000 that 1 second has elapsed) (S612)
.

A process in which the effective area determination unit 1100 determines whether the pointer coordinates are within the effective area using the application-specific effective area information will be described. FIG. 8 shows a processing flow of the effective area determination unit 1100, and FIG. 9 shows an example of application-specific effective area information.
Upon receiving a request for determining whether or not the pointer coordinates are within the valid area from the no-operation counting unit 601, the valid area determining unit 1100 confirms the application identification (S1101) and calculates the valid area based on the valid area information for each application. (S1102).
In the example of FIG. 9, in the case of the menu application, the X coordinate of the effective area is 640 (the upper left coordinate X coordinate 660
The value obtained by subtracting the margin 20 from) to 1280 (the X coordinate 660 of the upper left coordinate plus the width 600 and the margin 20). The Y coordinate of the effective area is from 420 (a value obtained by subtracting the margin 20 from the Y coordinate 440 in the upper left coordinate) to 660 (a value obtained by adding the height 200 and the margin 20 to the Y coordinate 440 in the upper left coordinate).
The effective area determination unit 1100 acquires pointer coordinates from the no-operation counting unit 601 (S1103), and determines whether the pointer coordinates are within the effective area calculated in step S1102 (S1104).
When the pointer coordinates are within the valid area (Y in S1104), the valid area determining unit 1100 determines that the pointer is valid (S1105). In this case, the process of Y in step S618 is performed, and the count of the no-operation period is reset.
If the pointer coordinates are not within the valid area (N in S1104), the valid area determination unit 1100 determines that the pointer coordinates are invalid (S1106). In this case, the process in the case of N in step S618 is performed, and the count of the non-operation period is continued.
For example, in the case of a menu application, if the pointer coordinate is (650,500), “valid”
If the pointer coordinates are (630,500), it is determined as “invalid”.
In this embodiment, the no-operation counting unit 601 and the effective area determination unit 1100 correspond to the control unit of the present invention.

As described above, according to the present embodiment, at the time of three-dimensional operation, even when the pointer coordinates are off the operation screen, if the pointer coordinates are within the margin area set on the operation screen, It is not counted as a no-operation period. Accordingly, even when the pointer is unintentionally detached from the operation screen due to a user's camera shake or a side look during a three-dimensional operation, it is suppressed from being regarded as a no-operation state. Accordingly, it is possible to suppress the operation screen from disappearing against the user's intention due to the no-operation timeout process during the three-dimensional operation.

(Example 3)
In the digital broadcast receiving apparatus according to the present invention, when the remote control operation for operating the operation screen with an operation type different from the operation type assumed by the operation screen is performed, the no-operation timeout time is set to be long. Therefore, when the remote control operation is performed by 3D operation when the operation screen for key operation is output, or when the remote control operation is performed by key operation when the operation screen for 3D operation is output, It becomes difficult to reach the no-operation timeout time. Therefore, when a remote control operation of an operation type different from the assumed operation type is performed, it is difficult to execute the no-operation timeout process. As a result, even in a digital broadcast receiving apparatus that outputs an operation screen that can be operated by either a remote control operation of a key operation or a three-dimensional operation, a no-operation time-out process is executed against the user's intention. Can be suppressed.

  In the present embodiment, when the operation screen varies depending on the remote control operation type, a case will be described in which the no-operation timeout time of the operation screen is determined depending on which operation type screen is operated with which operation type.

The functional block diagram of the digital broadcast receiving apparatus of this embodiment is equivalent to the functional block diagram of FIG. 1 described in the first embodiment. However, since the processing contents of the non-operation counting unit, the application unit, and the timeout time determining unit are different from those in the first embodiment, the signs are changed in this embodiment to determine the non-operation counting unit 602, the application unit 401, and the timeout time, respectively. Part 501. The following description will focus on differences from the first embodiment.

When the application unit 401 acquires the key code and remote control operation type information from the user interface unit 200, the application unit 401 creates an operation screen corresponding to the remote control operation type of the application corresponding to the key code and passes it to the GUI superimposing unit 900.
When the application unit 401 requests the timeout time determination unit 501 to determine the timeout time, the application unit 401 passes the information on the screen type of the application operation screen (key operation screen or 3D operation screen) to the timeout time determination unit 501. . Other points are the same as the application unit 400 of the first embodiment.
In the present embodiment, the application unit 401 corresponds to the output unit of the present invention.

Upon receiving a non-operation timeout time determination request from the application unit 401, the timeout time determination unit 501 determines the no-operation timeout time with reference to the application-specific / screen type-specific timeout time information and passes it to the application unit 401. Here, the time-out time information for each application / screen type defines the initial value of the no-operation time-out time for the key operation screen, the initial value of the no-operation time-out time for the 3D operation screen, and the premium rate for each application It is a table. Here, the premium rate is a rate for increasing and correcting the no-operation timeout time when the screen type of the operation screen does not match the remote control operation type acquired during the no-operation period count. Details will be described later. The timeout time determining unit 501 holds the timeout time information for each application and each screen type. Details of the timeout time determination unit 501 will be described later.

Upon receiving the no-operation count request from the application unit 401, the no-operation counting unit 602 counts the no-operation period. Here, the no-operation period is a period in which a key code or pointer coordinates from the user interface unit 200 is not passed.
When the no-operation period reaches the no-operation timeout time designated by the application unit 401, the no-operation counting unit 602 notifies the application unit 401 accordingly. The no-operation counting unit 602 of the present embodiment is different from the first embodiment in that the no-operation timeout time is reset when the remote control operation type changes during the no-operation period count. Details of the non-operation counting unit 602 will be described later.

A process in which the timeout time determination unit 501 determines the no-operation timeout time using the timeout information for each application and each screen type will be described.
FIG. 10 shows a processing flow of the timeout time determining unit 501, and FIG. 11 shows an example of timeout time information for each application and each screen type.
Upon receiving the no-operation timeout time determination request from the application unit 401, the timeout time determination unit 501 confirms the application identification and the screen type of the operation screen (S511). Here, the screen type information is information indicating whether the operation screen is a key operation screen or a three-dimensional operation screen.
Next, the timeout time determination unit 501 acquires the initial value of the no-operation timeout time for the application and screen type confirmed in step S511 from the timeout information for each application and each screen type. Then, this value is set as the no-operation timeout time (S512). In the example of FIG. 11, the initial value of the no-operation timeout time for the menu application is set to 1 minute if the screen type is a key operation, and 1 minute 6 seconds if the screen type is a three-dimensional operation.
Next, the timeout time determination unit 501 acquires a remote control operation type from the application unit 401 (S513), and determines whether the remote control operation type matches the operation screen type (S514).
If the remote control operation type matches the operation screen type (Y in S514), the timeout time determination unit 501 ends the no-operation timeout time determination process. In the example of FIG. 11, the no-operation time-out time is set to 1 minute when the operation screen type is key operation and the remote control operation type acquired in step S513 is key operation. When the operation screen type is a three-dimensional operation and the remote control operation type acquired in step S513 is a three-dimensional operation, the no-operation timeout time is set to 1 minute 6 seconds.
When the remote control operation type and the operation screen type do not match (N in S514), the timeout time determination unit 501 acquires an additional rate for this application from the timeout information for each application and each operation type. Then, the no-operation timeout time is corrected to be increased according to this premium rate (S515), and the no-operation timeout time determination process is completed. In the example shown in Fig. 11, the no-operation timeout period is 3 for the remote control operation type when the screen type is key operation.
For dimension operations, it is set to 1 minute 6 seconds with an increase of 10%. In addition, when the screen type is a three-dimensional operation and the remote control operation type is a key operation, the no-operation timeout time is set to 1 minute 13 seconds, which is 10% higher than 1 minute 6 seconds.

A process in which the no-operation counting unit 602 counts the no-operation period based on the designated no-operation timeout time will be described. FIG. 12 shows a processing flow of the no-operation counting unit 602.
When receiving the no-operation count request from the application unit 401, the no-operation counting unit 602 acquires and stores the screen type (S621). The subsequent processing of step S622 to step S626 is equivalent to the processing of step S601 to step S605 of FIG.
In this embodiment, when a three-dimensional operation or key operation has occurred in step S626 (Y in S626), the no-operation counting unit 602 matches the operation type of the generated remote control operation with the stored screen type. Check (S627). If no operation has occurred (N in S626)
), The process returns to step S623.
When the generated operation type matches the stored screen type (Y in S627), the no-operation counting unit 602 resets the no-operation timeout time set in step S622 to the count value and counts the no-operation period. Is reset (S622).
If the generated operation type does not match the stored screen type (N in S627), the no-operation counting unit 602 re-stores the operation type (S628) and sets a new no-operation timeout time corrected by increasing the premium rate. Obtained from the application unit 401 (S629). Then, the acquired no-operation timeout time is reset to the count value, and the no-operation period count is reset (S622).
For example, if the remote control operation type when the user interface unit 200 first issues a menu screen call instruction is a key operation, the application unit 401 creates a menu screen for a key operation screen. Thereafter, when a key operation occurs during the no-operation period count, the no-operation timeout period remains 1 minute, the count value is set to 1 minute, and the no-operation period starts counting. On the other hand, when a three-dimensional operation occurs during the no-operation period count, the no-operation timeout time is corrected to be increased to 1 minute 6 seconds, the count value is set to 1 minute 6 seconds, and the no-operation period count is started. If a key operation occurs during the no-operation period count with the no-operation timeout time set to 1 minute 6 seconds, the no-operation timeout time is returned to 1 minute and the count value is set to 1 minute. Start counting.
In this embodiment, the no-operation counting unit 602 corresponds to the control unit of the present invention.

As described above, in this embodiment, the remote control operation of the operation type assumed by the operation screen is performed as in the case of performing the three-dimensional operation on the key operation screen or the key operation on the three-dimensional operation screen. If not, a long no-operation timeout period is set. As a result, it is possible to prevent the operation screen from disappearing due to the no-operation time-out process regardless of the user's intention, whether the user operates the remote control by key operation or the 3D operation when outputting the operation screen. .

Each example described above is an exemplification of the embodiment of the present invention, and the above-described example may be modified within the technical scope of the present invention. For example, in each of the above embodiments, the key operation and 3
Although an example has been described in which the operation type is determined based on the remote control signal format using a remote controller capable of both dimension operations, the key operation remote controller and the three-dimensional operation remote controller may be separate. In that case, information identifying which remote control signal is issued is added to the remote control signal, and the remote control signal processing unit 100 determines the operation type of the remote control with reference to the identification information. May be.
The present invention provides a video output device that outputs an operation screen that operates in conjunction with both key operation and three-dimensional operation types, as well as a digital broadcast receiver, such as a recorder, a media player, and a game machine. It can also be applied to video output devices.
