Abstract

PROBLEM TO BE SOLVED: To provide a content reproduction device capable of improving the convenience of a UO-masked operation while maintaining control of the operation using a UO mask in content.SOLUTION: The content reproduction device includes a signal processing part for acquiring UO mask information that specifies a UO mask for inhibiting a specific operation in accordance with contents of content, and an information processing part for holding an operation accepted by an external I/F processing part during content data reproduction in the case that the operation is inhibited by UP mask, and executing the held operation when determining that the UP mask is released on the basis of the UO mask information acquired by the signal processing part.

Description

  The present invention relates to a content reproduction apparatus that reproduces content data.

In recent years, players that play back content data recorded on recording media such as BDMV (Blu-ray Disc Movie (registered trademark)) and DVD-Video have become widespread.
The user can insert a recording medium into the player and perform operations such as playback of content data, pause of playback, and fast-forward / rewind.

  On the other hand, a content creator can set playback control for content data at the time of content creation. For example, it can be set so that the user cannot pause or fast-forward during playback of a specific scene. Such a setting is called a UO (User Operation) mask. When the user requests a UO masked operation, the player outputs a warning sound or displays a screen notifying that the operation is prohibited.

  The UO mask can be set in various ways depending on the content. For this reason, the user can know that the requested operation is prohibited by the UO mask by the above warning or the like, but at what timing the operation can be executed, that is, the UO mask It is not possible to know when to be released. In such a case, conventionally, the operation is repeatedly requested until the UO mask is released.

  For example, Patent Document 1 discloses an AV system having means for presenting a user with prohibition and cancellation of an operation using a UO mask. This AV system detects, for example, whether each operation is currently prohibited or permitted in parallel with DVD playback, and indicates that the operation is prohibited or permitted. Present in

Japanese Patent Laid-Open No. 11-312042

Prohibiting the execution of the operation requested by the user using the UO mask is not a problem as the standard operation intended by the content creator.
However, since it is impossible to know the timing at which the UO mask is released, it is necessary to repeat the operation request as described above, or to wait more than necessary until the operation becomes possible.

  Even if it is indicated that the operation is prohibited or permitted as in Patent Document 1, after all, the user needs to wait for presentation that the operation is permitted. For this reason, if the user does not pay much attention to the presentation contents of the presentation means, there is a possibility of waiting for an unnecessarily long time before executing the operation by missing the release timing of the UO mask.

  The present invention has been made in order to solve the above-described problems, and content reproduction capable of improving the convenience of an operation masked with UO while maintaining the control of the operation using the UO mask in the content. The object is to obtain a device.

  The content playback apparatus according to the present invention includes an external I / F processing unit that receives an operation from a user, and controls the content data playback in accordance with the operation received by the external I / F processing unit. And a signal processing unit that acquires UO mask information that defines a UO mask that prohibits a specific operation according to the operation, and an operation accepted by the external I / F processing unit during playback of content data is prohibited by the UO mask. An information processing unit that holds the operation and executes the held operation when it is determined that the UO mask is released based on the UO mask information acquired by the signal processing unit. .

Embodiment 1 FIG.
FIG. 1 is a block diagram showing a configuration of a content reproduction apparatus according to the present invention. For example, the content reproduction apparatus 1 shown in FIG. 1 is a content reproduction apparatus that reproduces content data recorded on a disk d that is a recording medium, and includes an optical pickup 2, a signal processing unit 3, an AV decoder 4, and an AV output unit 5. , A monitor 6, an operation input unit 7, an external I / F processing unit 8, an information processing unit 9, and a nonvolatile memory 10.

The optical pickup 2 reads a recording signal from the disk d, converts it into an AV stream, and outputs it to the signal processing unit 3.
The signal processing unit 3 is a signal processing unit that outputs the AV stream from the optical pickup 2 to the AV decoder 4 and acquires UO mask information recorded on the disk d via the optical pickup 2. Here, the UO mask information is information that defines a UO mask that prohibits a specific operation in accordance with the content recorded on the disc d.

The AV decoder 4 is a decoder that decodes an AV stream into video and audio output data. The AV output unit 5 receives the video and audio output data obtained by the AV decoder 4 decoding the AV stream, displays the video on the screen of the monitor 6, and outputs the audio through the speaker of the monitor 6. The non-volatile memory 10 is a memory that stores reproduction position information as resume reproduction information at the next reproduction start when reproduction of the disk d is stopped.
The nonvolatile memory 10 is used to hold user setting information.

The operation input unit 7 is an operation input unit that receives a user operation input, and receives an operation using, for example, a hardware key, a touch panel, and a remote controller (hereinafter abbreviated as a remote controller) 11. The operation input unit 7 constitutes an HMI (Human Machine Interface) that is interposed between the user and receives a user operation.
An operation signal input using the remote controller 11 or the like is output to the information processing unit 9 via the external I / F processing unit 8. The information processing unit 9 executes user request processing according to the operation signal.

  Further, the information processing section 9 determines whether or not operation is prohibited based on the UO mask information stored in the disk d, and gives a control instruction to the AV decoder 4. In other words, when the UO mask is set for the process requested by the user, the information processing section 9 instructs the AV decoder 4 to display that the UO mask is set, for example, a prohibition mark. When the operation requested by the user is a GUI (Graphical User Interface) displayed on the monitor 6, the AV output unit 5 superimposes a prohibition mark or the like on the GUI screen.

  Further, in the information processing unit 9 according to the first embodiment, when the operation accepted by the external I / F processing unit 8 is prohibited by the UO mask while the content data on the disc d is being reproduced. The operation is held in, for example, the nonvolatile memory 10 and the held operation is executed when it is determined that the UO mask is released based on the UO mask information acquired by the signal processing unit 3.

Next, the operation will be described.
FIG. 2 is a flowchart showing the operation of the content reproduction apparatus according to the first embodiment, and shows processing when an operation request is received from the user during reproduction of content data stored on the disk d.
First, the user makes an operation request using the operation input unit 7 or the remote controller 11 (step ST1). An operation request from the user is input to the information processing unit 9 via the external I / F processing unit 8. The information processing unit 9 analyzes the operation request from the user, determines which operation is requested, and inquires of the signal processing unit 3 whether or not there is UO mask information for the operation of the determination result.

The signal processing unit 3 searches the disc d for UO mask information for the operation of the determination result via the optical pickup 2.
Based on the search result, the information processing section 9 determines whether or not a UO mask is set for the operation requested by the user (step ST2). Here, if the UO mask is not set (step ST2; NO), the information processing section 9 executes an operation requested by the user (step ST3).

When the UO mask is set (step ST2; YES), the information processing section 9 determines whether or not the user has set the automatic execution function (step ST4). For example, when a user sets an automatic execution function using the operation input unit 7 or the remote controller 11 when reproducing the content of the disk d, the information processing unit 9 stores the fact in the nonvolatile memory 10, and A determination is made based on the stored contents.
The setting of the automatic execution function will be described later with reference to FIG.

If it is determined that the automatic execution function is not set (step ST4; NO), the information processing section 9 instructs the AV decoder 4 to display the UO mask with a prohibition mark or the like.
The AV decoder 4 decodes a prohibition mark or the like indicating a UO mask and outputs it to the AV output unit 5. As a result, the AV output unit 5 displays a UO mask such as a prohibition mark on the screen of the monitor 6 (step ST7).

  On the other hand, when the automatic execution function is set (step ST4; YES), the information processing section 9 determines whether or not the operation requested by the user is an operation subject to automatic execution (step ST5). For example, when the automatic execution function is set, an operation for the target is input, and the information processing unit 9 stores the operation in the nonvolatile memory 10. This operation is read from the nonvolatile memory 10 to make a determination.

If the operation is not an automatic execution target operation (step ST5; NO), the information processing section 9 shifts to the processing of step ST7 and causes the monitor 6 to display the UO mask for this operation.
If the operation is an operation subject to automatic execution (step ST5; YES), the information processing section 9 holds this operation in the nonvolatile memory 10 (step ST6). Thereafter, the process proceeds to the process of FIG.

FIG. 3 is a flowchart showing a flow of an automatic execution process of an operation for which a UO mask is set. The process of FIG. 3 is executed after the process when the operation request from the user shown in FIG. 2 is received is completed. Is done. First, the information processing section 9 starts monitoring the UO mask at a constant cycle while reproducing the content data (step ST1a). Here, the subsequent processing is executed at a constant cycle.
Next, the information processing section 9 determines whether or not the user has set the automatic execution function (step ST2a). The determination method is the same as step ST4 in FIG.
If the automatic execution function is not set (step ST2a; NO), the process proceeds to step ST7a.

When the automatic execution function is set (step ST2a; YES), the information processing section 9 refers to the storage content of the nonvolatile memory 10 and determines whether or not there is an operation held in step ST6 of FIG. (Step ST3a).
If there is no operation held in the nonvolatile memory 10 (step ST3a; NO), the process proceeds to step ST7a.

When there is an operation held in the nonvolatile memory 10 (step ST3a; YES), the information processing unit 9 instructs the signal processing unit 3 to acquire the current UO mask information related to the operation held in the nonvolatile memory 10. (Step ST4a).
Subsequently, the information processing section 9 determines whether or not the UO mask for the above operation has been released based on the UO mask information acquired from the signal processing section 3 (step ST5a).
If the UO mask is not released (step ST5a; NO), the process proceeds to step ST7a.

On the other hand, when the UO mask is released (step ST5a; YES), the information processing section 9 executes an operation corresponding to the current UO mask held in the nonvolatile memory 10 (step ST6a).
In step ST7a, the information processing section 9 executes reproduction information update processing. For example, when the operation is executed in step ST6a and the reproduction information of the content is changed, a process of updating with this is performed.

FIG. 4 is a diagram showing an outline of automatic execution processing of an operation for which a UO mask is set, and shows a case where the operation is “fast forward”. In FIG. 4, on the screen 6a of the monitor 6, the moving image content (face image) is reproduced and displayed. At this time, if the user requests a “fast forward” operation using the remote controller 11, since the UO mask is set for the “fast forward” operation, the prohibition mark 6 b is displayed on the screen 6 a and the “fast forward” operation is performed. The operation is not performed.
Thereafter, when the UO mask is released, the information processing section 9 immediately starts executing the “fast forward” operation. At this time, a fast-forward mark 6c is displayed on the screen 6a.

  As described above, according to the first embodiment, the signal processing unit 3 that acquires the UO mask information that defines the UO mask that prohibits a specific operation according to the content, and the reproduction of the content data, When the operation accepted by the external I / F processing unit 8 is prohibited by the UO mask, the operation is retained and it is determined that the UO mask has been released based on the UO mask information acquired by the signal processing unit 3 And an information processing unit 9 that executes the stored operation at the time. By configuring in this way, it is possible to improve the convenience of the UO masked operation while maintaining the control of the operation using the UO mask in the content.

Embodiment 2. FIG.
In the second embodiment, when an operation in which a UO mask is set is requested, another operation that obtains the same or similar processing result as this operation is executed. Even in this way, it is possible to obtain the same processing result as the UO masked operation or a similar processing result while maintaining the control of the operation using the UO mask in the content, thereby improving the convenience for the user. Can do.
Note that the content reproduction apparatus according to the second embodiment has basically the same configuration as the apparatus according to the first embodiment, and therefore the configuration of the apparatus will be referred to FIG. 1 in the following description.

Next, the operation will be described.
FIG. 5 is a flowchart showing the operation of the content reproduction apparatus according to the second embodiment of the present invention, and shows the processing when there is an operation request from the user during reproduction of the content data stored on the disk d. .
First, the user makes an operation request using the operation input unit 7 or the remote controller 11 (step ST1b). An operation request from the user is input to the information processing unit 9 via the external I / F processing unit 8. The information processing unit 9 analyzes the operation request from the user, determines which operation is requested, and inquires of the signal processing unit 3 whether or not there is UO mask information for the operation of the determination result.

Next, the signal processing unit 3 searches the optical pickup 2 for UO mask information for the operation of the determination result from the disk d.
Based on the search result, the information processing section 9 determines whether or not a UO mask is set for the operation requested by the user (step ST2b). Here, if the UO mask is not set (step ST2b; NO), the information processing section 9 executes an operation requested by the user (step ST3b).

When the UO mask is set (step ST2b; YES), the information processing section 9 determines whether or not the user has set the replacement execution function (step ST4b).
For example, when the content of the disc d is reproduced, if the replacement execution function is set by the user using the operation input unit 7 or the remote controller 11, the information processing unit 9 stores the fact in the nonvolatile memory 10, and this A determination is made based on the stored contents. The setting of the replacement execution function will be described later with reference to FIG.

If it is determined that the replacement execution function is not set (step ST4b; NO), the information processing section 9 instructs the AV decoder 4 to display the UO mask with a prohibition mark or the like.
The AV decoder 4 decodes a prohibition mark or the like indicating a UO mask and outputs it to the AV output unit 5. As a result, the AV output unit 5 displays a UO mask such as a prohibition mark on the screen of the monitor 6 (step ST8b).

  When the replacement execution function is set (step ST4b; YES), the information processing section 9 determines a similar operation to the operation requested by the user (step ST5b). Here, based on the UO mask information acquired by the signal processing unit 3, the information processing unit 9 obtains a UO mask from other operations that can obtain the same or similar processing result as the operation requested by the user. An operation that is not set is discriminated, and a similar operation is determined. The details of the similar operation determination process will be described later with reference to FIGS.

If there is no similar operation (step ST6b; NO), the information processing section 9 proceeds to the process of step ST8b.
If there is a similar operation (step ST6b; YES), the information processing section 9 replaces the operation requested by the user and immediately executes this similar operation (step ST7b).

FIG. 6 is a flowchart showing the flow of determination processing for similar operations of “fast forward”.
First, when the information processing unit 9 starts to determine the similar operation of “fast forward” (step ST1c), the UO mask is set in the time search (Time Search) based on the UO mask information acquired by the signal processing unit 3. It is determined whether or not (step ST2c).
Here, the time search is an operation in which a playback position is a position advanced by the search time from the current playback position.
Further, the information processing unit 9 inputs a request amount of “fast-forward” (for example, fast-forwarding time with respect to a predetermined fast-forwarding speed) via the external I / F processing unit 8 and stores it in the nonvolatile memory 10.

If the UO mask is not set in the time search (step ST2c; NO), the information processing section 9 sets the fast-forward request amount of the user based on the “fast-forward” request amount stored in the nonvolatile memory 10 as described above. The corresponding search time is calculated (step ST3c).
Thereafter, the information processing section 9 determines the time search in which the search time calculated in step ST3c is set as a similar operation (step ST4c).
In the time search, if the search time corresponding to the user's fast-forwarding request amount can be accurately calculated, the same processing result as the fast-forwarding can be obtained.

When the UO mask is set in the time search (step ST2c; YES), the information processing section 9 determines whether or not the UO mask is set in the skip next (Skip Next) (step ST5c). Here, the skip next is an operation for causing the next chapter to skip.
If no UO mask is set for the skip next (step ST5c; NO), the information processing section 9 determines the skip next as a similar operation (step ST4c).
This skip next corresponds to a case where the user requests fast-forwarding to the next chapter, and a processing result similar to fast-forwarding can be obtained.

If the UO mask is set in the skip next (step ST5c; YES), the information processing section 9 determines whether or not the UO mask is set in the chapter search (Step ST6c). Here, the chapter search is an operation for shifting to a desired chapter (search target).
If the UO mask is not set in the chapter search (step ST6c; NO), the information processing section 9 sets the next chapter as a search target in the chapter search (step ST7c), and confirms this chapter search as a similar operation. (Step ST4c). This chapter search corresponds to a case where the user requests fast-forwarding to the next chapter, and a processing result similar to fast-forwarding can be obtained.

When the UO mask is set in the chapter search (step ST6c; YES), the information processing section 9 determines whether or not the UO mask is set in the title search (Title Search) (step ST8c). Here, the title search is an operation for shifting a desired title (search target).
If no UO mask is set for the title search (step ST8c; NO), the information processing section 9 sets the next title as a search target for the title search (step ST9c), and confirms this title search as a similar operation. (Step ST4c).
Note that this title search corresponds to a case where the user requests fast-forward to the next title, and a processing result similar to fast-forward can be obtained.

If the UO mask is also set for the title search (step ST8c; YES), the information processing section 9 determines that there is no similar operation to the fast-forward operation requested by the user (step ST10c). This process corresponds to the case where there is no similar operation in step ST6b of FIG.
As shown in FIG. 6, the information processing unit 9 performs an operation for obtaining the same processing result when there are a plurality of operations for obtaining the same or similar processing result as the operation prohibited by the UO mask. Are prioritized over operations that yield similar processing results.
That is, in the case of fast-forwarding, determination is made in order starting from a time search in which the same processing result can be obtained by setting the search time accurately. If it is determined that the operation is similar, the operation is confirmed as a similar operation.
By doing so, it is possible to preferentially execute an operation that obtains the same processing result as the operation for which the UO mask is set, and it is possible to improve user convenience.

FIG. 7 is a diagram showing an outline of execution processing of a similar operation, and shows a case where the operation is “fast forward”. In FIG. 7, “title 1 chapter 1” of the moving image content is reproduced on the screen 6 a of the monitor 6. At this time, when the user requests a “fast forward” operation using the remote controller 11, since the UO mask is set for the “fast forward” operation, the prohibition mark 6b is displayed on the screen 6a and the “fast forward” operation is performed. Is not executed.
If the requested amount of “fast forward” at this time is from the playback position (12:34) to the playback position (13:00), the information processing section 9 performs a time search with the search time set to 13:00. Replace with fast forward and execute. Thereby, the moving image at the reproduction position (13:00) is displayed on the screen 6a.

FIG. 8 is a diagram illustrating an example of a selection screen for automatic execution and replacement execution. As shown in FIG. 8, on the selection screen 6A, the automatic execution selection button 6d shown in the first embodiment, the replacement execution selection button 6e shown in the second embodiment, and OFF for releasing these selections. Button 6f is arranged. The user selects and activates these buttons 6d to 6f using the operation input unit 7 or the remote controller 11, and inputs the input information to the information processing unit 9 via the external I / F processing unit 8. Is done. The information processing unit 9 sets automatic execution or replacement execution according to the input information, and cancels these settings.
By doing in this way, the user can freely set automatic execution and replacement execution and cancel these settings based on the selection screen 6A.

  FIG. 9 is a flowchart showing the flow of determination processing for a similar operation of “fast rewind”. The processing from step ST1d to step ST10d in FIG. 9 corresponds to the case where the playback position is shifted in the direction of returning in the processing from step ST1c to step ST10c in FIG.

FIG. 10 is a flowchart showing the flow of determination processing for a similar operation of “skip next”. First, when the information processing unit 9 starts to determine the similar operation of “skip next” (step ST1e), is the UO mask set in the chapter search based on the UO mask information acquired by the signal processing unit 3? It is determined whether or not (step ST2e).
If the UO mask is not set in the chapter search (step ST2e; NO), the information processing section 9 sets the next chapter as a search target in the chapter search (step ST3e), and confirms this chapter search as a similar operation. (Step ST4e). This chapter search corresponds to a case where the user skips to the next chapter, and can obtain the same processing result as the skip next.

  When the UO mask is set for the chapter search (step ST2e; YES), the information processing section 9 determines whether or not the UO mask is set for the title search (step ST5e). If the UO mask is not set for the title search (step ST5e; NO), the information processing section 9 sets the next title as a search target for the title search (step ST6e), and performs similar operations for this title search. (Step ST4e). Note that this title search corresponds to a case where the user requests a skip next to the content of the next title, and a processing result similar to the skip next can be obtained.

  If the UO mask is also set for the title search (step ST5e; YES), the information processing section 9 determines that there is no similar operation to the skip next operation requested by the user (step ST7e). This process corresponds to the case where there is no similar operation in step ST6b of FIG.

  FIG. 11 is a flowchart showing a flow of determination processing for a similar operation of “skip back”. The processing from step ST1f to step ST7f in FIG. 11 corresponds to the case where the playback position is shifted in the direction of returning in the processing from step ST1e to step ST7e in FIG.

FIG. 12 is a flowchart showing the flow of determination processing for a similar operation of “pop-up on”. Pop-up on is an operation that permits display of a pop-up, and for example, a menu screen is displayed as a pop-up.
First, when the information processing unit 9 starts to determine a similar operation of “pop-up on” (step ST1g), whether or not a UO mask is set in the menu call based on the UO mask information acquired by the signal processing unit 3 is determined. Is determined (step ST2g).
Here, the menu call is an operation for calling a menu screen.

If no UO mask is set for the menu call (step ST2g; NO), the information processing section 9 determines the menu call as a similar operation (step ST3g).
Since this menu call is an operation for calling the menu screen, it corresponds to the case where the menu screen is displayed as a pop-up, and the same processing result as pop-up on may be obtained.
If the UO mask is set for the menu call (step ST2g; YES), the information processing section 9 determines that there is no similar operation to the pop-up on operation requested by the user (step ST4g). This process corresponds to the case where there is no similar operation in step ST6b of FIG.

  FIG. 13 is a flowchart showing the flow of determination processing for a similar operation of “menu call”. First, when the information processing unit 9 starts to determine a similar operation of “menu call” (step ST1h), is the UO mask set to pop-up on the basis of the UO mask information acquired by the signal processing unit 3? It is determined whether or not (step ST2h).

If the UO mask is not set for pop-up on (step ST2h; NO), the information processing section 9 determines pop-up on as a similar operation (step ST3h).
Since this pop-up is an operation for displaying the menu screen as a pop-up, the same processing result as the menu call may be obtained.
If the UO mask is set for pop-up ON (step ST2h; YES), the information processing section 9 determines that there is no similar operation to the menu call operation requested by the user (step ST4h). This process corresponds to the case where there is no similar operation in step ST6b of FIG.

FIG. 14 is a flowchart showing a flow of determination processing for similar operations of the “title menu”. Here, the title menu is an operation for displaying a menu screen on which each title of the moving image content is arranged.
First, when the information processing unit 9 starts to determine a similar operation of the “title menu” (step ST1i), whether or not a UO mask is set in the root menu based on the UO mask information acquired by the signal processing unit 3 is determined. Is determined (step ST2i).
Here, the root menu is an operation for displaying a menu screen in which a chapter menu, an audio menu, a subtitle menu, and an angle menu are arranged in the moving image content.

If the UO mask is not set in the root menu (step ST2i; NO), the information processing section 9 determines the root menu as a similar operation (step ST3i).
Note that this root menu is an operation for displaying a menu screen on which a subtitle menu or the like is arranged, so that a processing result similar to the title menu can be obtained.
When the UO mask is set in the root menu (step ST2i; YES), the information processing section 9 determines that there is no similar operation in the title menu operation requested by the user (step ST4i). This process corresponds to the case where there is no similar operation in step ST6b of FIG.

  FIG. 15 is a flowchart showing the flow of determination processing for similar operations of the “root menu”. First, when the information processing unit 9 starts to determine the similar operation of the “root menu” (step ST1j), is the UO mask set in the title menu based on the UO mask information acquired by the signal processing unit 3? It is determined whether or not (step ST2j).

If no UO mask is set in the title menu (step ST2j; NO), the information processing section 9 determines the title menu as a similar operation (step ST3j).
Since the title menu is an operation for displaying a menu screen on which a title is arranged, a processing result similar to the root menu can be obtained.
If a UO mask is set in the title menu (step ST2j; YES), the information processing section 9 determines that there is no similar operation to the root menu operation requested by the user (step ST4j). This process corresponds to the case where there is no similar operation in step ST6b of FIG.
