Description

  The present invention relates to a playback apparatus and a playback method for playing back content according to playback function settings according to function setting information for each user use.

When viewing content on a playback device such as a display device such as a television or DVD player, the user can select screen settings such as contrast and sharpness from the menus displayed on the menu setting screen. It is widely performed to select and set setting contents such as voice settings such as main / sub voice and volume. Recently, this menu setting can be performed in multiple ways. Therefore, when there are multiple users on a single playback device, each of the multiple users can select their own settings according to their own preferences. You can also see what you can do. In this case, conventionally, an initial menu preset at the time of factory shipment of the playback apparatus is generally set by each user according to his / her preference.
For example, Patent Document 1 discloses a technique related to a television system in which each user can individually perform various settings by identifying the user (see Patent Document 1).
JP 2002-335513 A

By the way, a plurality of users who use one playback apparatus may have a common preference for setting contents, and only a part may be different. Conventionally, even in such a case, each of a plurality of users individually selects and sets the setting contents according to his / her preference.
However, when the playback functions are diversified and the menu setting contents are diversified, it is complicated to individually set each user's preferences until the preferences are basically common. For example, when there are four menu settings related to video, a brightness value, a contrast value, a sharpness value, and a color balance (tone correction) value, the user A sets all the values to “8”. Assume that user B has a preference that only the color balance value is set to “7” and the remaining value is set to “8”. In this case, for example, if the factory presets are all set to “5”, in the conventional method, the users A and B individually set all the menus. It is necessary to perform the setting operation once.
On the other hand, if the contents set by either one can be set by using the other, the setting operation becomes extremely easy. In the above example, if A is set for all menus and then B can be diverted, B only needs to change the color balance value from 8 to 7, so the setting operation for A and B Is reduced to 5 times in total, and the time required for this setting operation can be saved. In particular, with the widespread use of digital broadcasting, it is not possible to divert such a situation in light of recent circumstances such as the selection of various menus for broadcast data as well as video and audio. It is expected to become inconvenient, and it is increasingly necessary to realize menu settings that allow such diversion.

  In addition, for one user, for example, there is a case where it is desired to perform reproduction using a plurality of settings so that the volume value setting is changed between daytime and nighttime. Even in this case, it is possible for one user to use a plurality of such settings by considering the daytime and nighttime as separate users using the conventional technology, but one setting cannot be diverted to the other. Therefore, the same inconvenience occurs as described above. For example, assuming that there are four menu settings related to audio, ie, volume (volume) value, balance, bass, and Dolby ON / OFF selection, when the volume value is one (for daytime), “MAX value 60”, On the other hand (for nighttime), “MAX value 25” is set, and the other menus have the same setting contents. In this case, when changing the volume value from daytime to nighttime or from nighttime to daytime, the other menu settings are the same. It is inconvenient to repeat it.

  Therefore, the problems to be solved by the present invention include a case where a plurality of users can individually select setting contents for one playback device (including a case where one user can select a plurality of setting contents). In the following, the reproducing apparatus and the reproducing method can reduce the complexity of the setting operation of the user and save the time required for the setting operation by diverting the contents set by one user to the other.

<Overview>
The playback apparatus according to the present embodiment includes a unit for playing back content by playback function setting according to function setting information for each user use, a unit for storing function setting information used by the unit for each user use, and one user In order to change the function setting information for use, the function setting information relating to some functions among the function setting information for use by other users is copied and changed.

<Configuration>
FIG. 1 is a diagram illustrating an example of functional blocks of the playback apparatus according to the present embodiment. Each unit, which is a component of the present invention, is configured by either hardware, software, or both hardware and software. For example, as an example for realizing these, when a computer is used, hardware composed of a CPU, a memory, a bus, an interface, peripheral devices, and the like, and software executable on these hardware are listed. Can do. Specifically, the functions of the respective units are realized by sequentially executing the programs developed on the memory, by processing, storing, and outputting data on the memory and data input through the interface.

As shown in the figure, the “reproducing device” 0100 of this embodiment includes a “reproducing unit” 0101, a “storing unit” 0102, and a “changing unit” 0103. In addition, the “change unit” may include “update information holding unit” 0104, “copy unit” 0105, and “change unit” 0106 as shown in FIG.
The “playback unit” is configured to play back content with playback function settings according to function setting information for each user use. The type of content does not matter. Therefore, it may be content including both video and audio, content including broadcast data, or content including only video and audio only. “Function setting information” refers to information for controlling content playback conditions and the like. Specific examples of “function setting” include the following. Information related to video (herein referred to as “viewing related information”) includes brightness value, contrast value, sharpness value, color balance (tone correction), playback speed (normal playback, double speed playback, slow motion). Motion playback). Examples of the audio-related information include volume value, balance, bass, Dolby ON / OFF selection, main / sub audio selection, speaker / earphone selection, stereo / monaural selection, and the like. The information related to the OSD display can include font size selection, menu design selection, and the like. In addition, the presence or absence of channel display or other menu display, the presence or absence of display of electronic program information (EPG) or other broadcast data in the case of broadcast data can be exemplified. Furthermore, initial channel setting, timer function ON / OFF, energy saving mode selection, and the like can be given. For example, when the playback device is a display device such as a television, the operation for setting the function is performed by an input by pressing a button on the remote controller.

  FIG. 2 is a conceptual diagram showing an example of a remote controller such as a television set on which keys for such function setting operations are arranged. As described above, the playback device of the present embodiment is configured to play back by playback function settings in accordance with the function setting information for each user use, and for this reason, the function settings are made for each user use. . Also in the example shown in the figure, reflecting this, a “user switching menu key” 0206 is provided on the remote controller. The remote controller shown in the figure is also provided with a “menu key” 0205 for selecting function setting contents. Then, based on the input from the “user switching menu key” and “menu key”, the playback function setting process according to the function setting information for each user use can be executed. A specific configuration for executing the processing will be described later.

The “storage unit” is configured to store function setting information used by the playback unit every time the user uses it.
The “changing unit” is configured to copy and change function setting information related to some functions among the function setting information used by other users in order to change the function setting information used by one user. For example, according to the above-described example, the function setting information of one user B is changed from “Brightness value 5, contrast value 5, sharpness value 5, color balance value 5” to “Brightness value 8, contrast”. When changing to “value 8, sharpness value 8, color balance value 7”, the function setting information for the A user who is already another user is set to “brightness value 8, contrast value 8, sharpness value 8, color balance value 8” Therefore, by copying the brightness value, contrast value, and sharpness value that uses the A-use function setting information, and setting only the color balance value individually, the entire function setting information is obtained. Will change. Note that “change” includes not only literally “changing” settings customized for other users, but also when customizing for users for the first time from the factory preset state as in the above example. The setting to be performed (that is, the change from the preset state) is also included.
As is clear from the above, the “reproducing apparatus” of the present embodiment is not limited to any type as long as it reproduces content by reproducing function setting according to function setting information for each user use. Typically, a display device such as a television, a DVD player, or a personal computer capable of reproducing video and audio is applicable, but the display device is not limited thereto, and may be an audio device that reproduces only audio.

  In addition, the “update information holding unit” included in the “change unit” is configured to temporarily hold the update information in order to change the stored function setting information in units of user use. The “copying means” copies function setting information related to some functions among the function setting information used by other users as update information to the update information holding unit in order to change the function setting information used by one user. It is configured as follows. The “changing unit” is configured to update and change the function setting information stored in the storage unit with the updating information held in the updating information holding unit. Here, the “update information” is information generated and held separately from the function setting information itself in order to be used for copying / changing the function setting information.

Therefore, a specific configuration related to copying / changing of the function setting information will be further described with a more detailed example. Here, an example in which the “change unit” includes “update information holding unit”, “copy unit”, and “change unit” will be described.
When the function setting information related to some functions among the function setting information used by other users is copied and changed, first, the user who is the setting target of the information is switched. For example, as described above, this is performed based on pressing of a “user switching menu key” provided on the remote controller. Hereinafter, the case of switching from the user A to the user B will be described with reference to this example.
First, when a “user switching menu key” provided on the remote controller is pressed, a user switching menu is displayed on the display screen of the playback device.

FIG. 3A shows a display example of such a user switching menu. This figure shows an example in which user B copies a part of user A's function setting information and diverts it as B's own function setting information. In this case, the user B is selected by moving the cursor with the cursor key 0208 provided on the remote control shown in FIG. FIG. 3A shows a state in which the user B is selected by such an operation. Next, when the enter key 0209 provided on the remote control shown in FIG. 2 is pressed again, the screen display is switched from the user switching menu to the setting content selection menu shown below.
FIG. 3B shows a display example of a setting content selection menu. In this case, as a selection menu, menus such as “viewing related”, “sound related”, and “OSD display related” are displayed on the screen so that the selection of YES / NO can be made as to whether or not the current setting contents are maintained. Note that “maintain the current setting contents” is an expression viewed from A as the copy source user (ie, another user), and the setting contents of the other user A are copied. This is the same as the example of “maintaining the current setting contents” below. Then, for example, in the case of “viewing-related”, if the selection is made to maintain the current setting contents of the function setting information (user A function setting information), the cursor is moved to the “Yes” position. When the enter key is pressed, all of the viewing-related function setting information that has already been set for user A is copied and becomes user B function setting information as it is. On the other hand, for example, for voice-related function setting information, there is a selection that part of the current function setting information is changed (that is, the setting contents of other user A's function setting information that is the current setting contents are not maintained). If it has been made, the screen is switched to the setting value storage area screen by moving the cursor to the “No” position and pressing the enter key. In the figure, “Yes” is selected for the viewing-related and OSD-related function setting information, and “No” is selected for the voice-related function setting information.

  4 and 20 show display examples of screens for setting value storage areas for changing sound-related function setting information. In the examples of these figures, the function setting information related to the use of the user A, which is the current setting, is displayed on the left side of the screen, and the function setting information related to the use of the user B is displayed on the right side. As for the function setting information related to the use of the user B, if there is information customized for the user B so far, for example, the latest information is displayed, and there is no customized information for the user B yet. For example, information in a preset state at the time of factory shipment is displayed. This example shows a case where the latest information among the information customized for the user B is displayed. When the user B selects to maintain B's own function setting information as it is, for example, by pressing the “return” key 0210 provided on the remote control shown in FIG. Return to the display screen. Also, instead of maintaining the current function setting information collectively, it is possible to select YES / NO as to whether or not to maintain the current information for each item such as “volume value” and “balance”. It may be. For example, although not shown, there is a display of YES / NO similar to the selection menu screen for setting contents in FIG. 3B next to each item for user B, and this can be selected by moving the cursor. May be. In this case, for example, the function setting information of the user B (“15” in accordance with the example in the figure) is maintained for the volume value, and the function setting information of the user B (in the example in the figure is used for the balance). "0") is not maintained, and the current function setting information of user A ("L1" according to the example in the figure) is maintained (that is, the function setting information of user A is copied to user B). The function setting information can be changed individually). Alternatively, a new value that is neither the latest function setting information of B itself nor the current function setting information of A for a certain item may be directly input. Then, after such individual selection or input is completed, the display screen of the selection menu of the original setting contents is returned by pressing the “return” key or the like as in the above example.

  Therefore, returning to FIG. 3B, the setting processing operation similar to the above-described viewing-related or audio-related is performed for the OSD display-related items as well, and if there are other functions, all selection menus including these are selected. When the processing operation is completed, the processing operation related to the setting content selection menu is completed based on the movement of the cursor to display YES at the bottom of the screen and the determination key being pressed.

Next, the hardware configuration of the playback apparatus of this embodiment will be described.
FIG. 5 is a schematic diagram illustrating an example of a hardware configuration of the playback apparatus according to the present embodiment. As shown in this figure, the playback unit of the playback device of the present embodiment includes “storage device” 0501, “main memory” 0502, “CPU” 0503, “I / O” 0504, and “display” 0506. Consists of The holding unit includes a “storage device”, a “main memory”, and a “CPU”. The changing unit includes “storage device”, “main memory”, “CPU”, “I / O”, and “remote control” 0505. These are connected to each other via a data communication path such as “system bus” 0507, and perform transmission / reception and processing of information.
The storage device stores various programs executed by the CPU. The main memory provides a work area which is a work area when the program is executed by the CPU. A plurality of memory addresses are assigned to the main memory and the storage device, respectively, and a program executed by the CPU performs processing by exchanging data with each other by specifying and accessing the memory address. It is possible.

First, a configuration for storing function setting information will be described. In this case, the playback device holds the information in advance or generates the information by itself, or obtains it from the outside and stores it in the storage device. As a case where the reproduction apparatus holds the information in advance, for example, a case where function setting information in a preset state at the time of factory shipment of the reproduction apparatus is set in advance can be considered. In addition, as a case where it is generated by itself, for example, a function setting information generation program is stored in a storage device in advance, and based on a function setting information generation command acquired via an interface by input using a remote controller, a keyboard, a mouse, or the like. Thus, a configuration in which the CPU executes the program to generate function setting information can be considered. In addition, as an acquisition source when storing function setting information acquired from the outside, for example, a recording medium such as a broadcast wave or a DVD-ROM can be considered.
In this example, it is assumed that function setting information A generated based on input from the remote control of user A is stored in the α area of the storage device. In this example, the function setting information A includes “brightness value 8, contrast value 5, sharpness value 6, color balance value −20” for viewing, and “volume value 10, balance L1, Bass1, Dolby OFF” for audio. It shall have setting contents. Such setting contents are input, for example, when the user A operates a user switching menu key, a cursor key, a determination key, or the like of the remote controller in the manner described above. Alternatively, the setting may be made as a copy / change process described below. For example, this corresponds to a case where function setting information preset at the time of shipment from the factory and stored in the storage device is read out and copied / changed. When the function setting information is stored in the storage device, the function setting information is stored in association with identification information (for example, information including an identification code such as A001) for indicating that this is related to the user A.
Similarly, function setting information B relating to user B is stored in the β area of the storage device. In this example, the function setting information B is set as “brightness value 0, contrast value 1, sharpness value 3, color balance value 10” for viewing-related, and “volume value 15, balance 0, Bass 8, Dolby ON” for sound-related. It shall have contents. Then, it is stored in association with identification information (for example, information consisting of an identification code such as B001) for indicating that this is related to the user B.

Next, a specific configuration when the function setting information B is changed while copying the setting contents of the partial function setting information A will be described. In this case, first, the copy / change program stored in advance in the storage device is expanded in the work area of the main memory, and the function setting information A and the function setting information B stored in the storage device are also read out to the main memory. Temporarily held in the data areas A and B of the memory. Then, the function setting information is copied / changed by the CPU executing the program. Specifically, for each setting content of the read function setting information A, based on a signal input from the remote controller through the I / O, a selection is made to maintain or change the setting content. If it is the former (maintaining the setting contents of the function setting information A), the setting contents of the function setting information A are copied as update information and temporarily stored in the main memory. Then, the setting contents of the function setting information B are replaced by this. This replacement processing is executed, for example, when the CPU executes a copy / change program to overwrite the data relating to the setting contents of the update information with the data relating to the setting contents of the function setting information B which is the copy destination. The On the other hand, in the latter case (changing the setting contents of the function setting information A), for example, the data relating to the setting contents of the function setting information B remains as it is. The selection of maintenance / change of the setting contents of the function setting information A may be performed in units such as viewing-related and audio-related, or may be performed in units such as brightness values and contrast values that are subdivided therein. .
For example, according to the example shown in FIG. 4 and FIG. 20, for the viewing related “brightness value 8, contrast value 5, sharpness value 6, color value −20” in the function setting information A, this setting content is used. Suppose that the selection to maintain is made. Then, the CPU executes the copying / changing program to copy (copy) the data of “brightness value 8, contrast value 5, sharpness value 6, color value −20”, and function setting up to that time by this data The setting content “Brightness value 0, contrast value 1, sharpness value 3, color value 10” of information B is replaced. On the other hand, in the function setting information A, the sound-related “volume value 10, balance L1, Bass1, Dolby OFF” is not maintained, and the current setting content of the function setting information B is “volume value 15, balance”. If it is selected that “0, Bass 8, Dolby ON” is left, no special processing is performed on this portion. As a result, the setting contents of the function setting information B read from the storage device are “brightness value 8, contrast value 5, sharpness value 6, color value −20” for viewing-related, and “volume value for sound-related”. 15, “balance 0, Bass 8, Dolby ON”. Therefore, the CPU associates the identification information concerning the user B with the changed function setting information, replaces this with the conventional function setting information B stored in the storage device as the function setting information B, and stores it. Hold.
Next, the content reproduction process is performed by the CPU executing a reproduction program. At that time, the processing is characterized in that it is performed according to the function setting information for each user usage generated and held by the above processing, but the specific configuration for the playback processing itself is not made using existing technology. Since this is an appropriate design matter for those skilled in the art, the description is omitted.

  The process described above is the same even when one user uses a plurality of pieces of function setting information to perform reproduction according to the settings. A specific example in such a case will be described in detail in another embodiment.

  In the above description, the example in the case of changing the function setting information for one user overwriting the function setting information for another user using the update information has been described. However, the change processing in this embodiment Is not necessarily performed using the update information. For example, the change processing may be performed by directly overwriting function setting information for one user based on information recorded on a recording medium such as an IC chip.

  Further, in the above description, an input for specifying a function to be changed, which is mainly made when changing function setting information for one user using function setting information for another user, is stored in the storage device. The description has been made on the assumption that the function setting information for use by other users is once read into the main memory, and the input is performed to specify the function to be used from that. In this case, regarding the function setting information read to the main memory, it is determined whether to maintain or change the setting contents one by one. However, the playback apparatus of the present embodiment is not limited to such a configuration. For example, the playback device is configured to receive and process only information specified as information related to a function selected as a change target in advance. In this case, it is not necessary to determine whether to maintain or change the setting contents.

  Although different from the configuration of the playback apparatus of the present invention, the changing unit sets the function setting related to “some functions” among the function setting information for other user use in order to change the function setting information for one user use. Instead of copying and changing information, it may be configured to copy and change function setting information related to “all or part of functions” among function setting information used by other users. For example, in the case of copying and changing the function setting information regarding all functions, for example, in accordance with the display example of the selection menu of setting contents shown in FIG. The setting information (user A's function setting information) is selected to be maintained, and for all menus, the cursor is moved to the “Yes” position and the Enter key is pressed, and the setting at the bottom of the screen is completed. The case where the cursor is moved and the determination key is pressed is displayed on the display of “YES”, and the processing operation related to the setting content selection menu is completed. As a result, the function setting information of user B is all copied and replaced with the same content as the function setting information of user A.

  Due to the above configuration, when changing the function setting information for one user (for example, B), the function setting information for another user (for example, A) matches the preference of the user (B). For the portion to be changed, it is not necessary to directly input the same value as A, and the value can be set as a changed value by a simple YES / NO selection operation using a cursor key or the like instead. Become. As a result, the complexity of the setting operation of the user is reduced, and the time required for the setting operation can be saved.

<Process flow>
FIG. 6 is a diagram illustrating an example of a processing flow in the playback apparatus of the present embodiment. The flow of processing in FIG.
First, in storage step S0601, the playback apparatus stores function setting information used for playback for each user use.
Next, in the reproduction step S0602, the reproduction apparatus reproduces the content with the reproduction function setting according to the function setting information for each user use saved in the saving step.
Next, in the copying / changing step S0603, the playback apparatus changes a part of the function setting information for other user use in order to change the function setting information for one user use used for playback in the playback step. Copy and change function setting information related to functions.
Next, in step S0604 of saving (after changing function setting information), the reproducing apparatus saves the changed function setting information when the function setting information is copied or changed in the copying / changing step.
Further, in the playback step (after the function setting information change) S0605, the playback device sets the content by the playback function setting according to the function setting information for each user use after the change stored in the storage step (after the function setting information change). Play.
Of the above steps, the processing in the saving step and the processing in the saving step (after changing the function setting information) are the functions setting information to be saved copied / changed in the copying / changing step. The only difference is whether it is a thing or not, and the processing content of the storage process itself is the same. The same applies to the processing in the playback step and the processing in the playback step (after changing the function setting information).

Next, the flow of processing in the copy / change step will be described in more detail with reference to another drawing.
FIG. 7 is a diagram showing an example of the processing flow in the copying / changing step. As shown in the figure, first, when it is determined in step S0701 whether or not to start work, if it is determined to start work, the reproduction device (specifically, in step S0702 for starting the copy / change program). The CPU constituting the changing unit (the same applies hereinafter) is activated by developing the copy / change program stored in the storage device in the main memory. Next, in step S0703 for accepting selection of setting information of another person that the user wants to use, the playback device selects function setting information related to the use of other users for each setting content of the function setting information related to the use of other users. Accept. This selection acceptance is executed by, for example, receiving a signal input from a remote controller through I / O. This signal is input, for example, by selecting whether to maintain or change the current setting contents for each setting contents of the function setting information by operating a key on the remote controller.
When the setting item related to the selection input in this way and received i-th (i is an integer starting from 1) is acquired (steps S0704 and S0705), the setting content related to the selected setting item is maintained. In step S0706 for selecting whether or not to change, the acquired setting contents of the function setting information related to the use of other users are maintained (that is, the setting contents of the function setting information related to the use of other users are copied to one user) "Change the setting contents of the function setting information related to use.)" Is selected, the function setting information is retained in order to maintain the setting contents of the function setting information related to other user use for the setting item i. In step S0707, the playback apparatus temporarily uses the function setting information for other user usage related to the setting contents as update information. On the other hand, in step S0706, the selection is made to change the setting contents of the function setting information related to other user use (in this example, the setting contents of the function setting information related to own use are maintained as they are). If so, the playback apparatus maintains the setting contents of the function setting information related to one user use as it is in step S0708 for maintaining the setting contents of the function setting information related to the use of the setting item i. As a result, the setting contents of the function setting information related to the use of one user remain unchanged.
When the processing in step S0707 or S0708 is performed, the process proceeds to step S0709 for determining whether i is the last. If it is determined that i is the last in the step, the stored setting information indicates In step S0710 for updating the setting information, the playback apparatus copies the temporarily stored update information and overwrites the data related to the setting contents of the function setting information for one user use (note that the step S0708 is described above). In step S0710, the processing in step S0710 is not performed). As a result, the processing for copying the setting contents of the function setting information related to the use of another user and changing the setting contents of the function setting information related to the use of one user is executed.
On the other hand, if it is determined in step S0709 that it is not the last, the process returns to step S0705, and the processing in step S0705 and subsequent steps is performed again. In step S0709, “i is the last”. The same process is repeated until a determination is made.
In the above description, the example in which the process in step S0710 is performed only after “i is the last” is determined in step S0709 is different. However, in this case, the update information is stored in step S0707. Whenever it is performed, a change process related to the setting contents of the function setting information for one user using the update information may be performed.

<Effect>
With the playback device of this embodiment, the content set by one user is diverted to the other, thereby reducing the complexity of the user's setting operation and saving the time required for the setting operation. It becomes possible to provide a method.

<Overview>
The playback apparatus of the present embodiment is basically the same as the apparatus of the first embodiment, but the changing unit specifies a function to be copied and diverted from the function setting information for use by the copying means to be copied. There is a feature in that it has means for receiving the input.

<Configuration>
FIG. 8 is a diagram illustrating an example of functional blocks of the playback apparatus according to the present embodiment. The “reproducing apparatus” 0800 of this embodiment is basically the same as the reproducing apparatus of the second embodiment. However, the “change unit” 0803 further includes a “function specific input unit” 0807.
The “function specifying input unit” is configured to receive an input for specifying a function to be copied and diverted from function setting information for user use to be copied by the copying unit. As used herein, “function” refers to a brightness value, a volume value, and the like, as in the first embodiment. Therefore, “input for specifying a function” refers to an input for specifying which of these functions is to be copied and diverted.

Here, “input for specifying a function” has two significances. One is an input for specifying the function to be changed when the function setting information for one user is changed with the function setting information for another user, as described in the first embodiment. Thus, the function setting information for use by other users stored in the storage device is once read into the main memory, and the input is performed to specify the function to be used from that. This input is made, for example, by selecting a function (for example, a volume value) displayed on the menu screen of the display by moving the cursor, similar to that described with reference to FIG. It is executed based on pressing of the enter key. In this sense, “input for specifying a function” is always accompanied by copying and changing function setting information in principle. In this case, in principle, the copying / changing process is performed in such a manner that all the functions are sequentially identified and whether the function setting information is to be maintained or changed.
The other one is different from this, in which function setting information relating to a function to be copied / changed is first specified, and only the information is read from the storage device to perform the copying / changing process. In this case, unlike the above, since only the function setting information to be copied / changed from the beginning is specified, it is not necessary to determine whether to maintain or change the function setting information. Specific differences relating to the copying / changing process in these two cases will be described in the processing flow described later.

  FIG. 9 is a schematic diagram illustrating an example of a hardware configuration of the playback apparatus according to the present embodiment. The hardware configuration of the playback apparatus of this embodiment is basically the same as that of the first embodiment. A specific configuration relating to copying / changing of the reproducing apparatus of this embodiment will be described below with reference to FIG. Here, an example in which the setting contents of another user A are copied to be the setting contents of one user B will be described. Since the remaining configuration is the same as that of the first embodiment, description thereof is omitted.

As shown in the figure, the changing unit of the playback device of this embodiment includes “storage device” 0901, “main memory” 0902, “CPU” 0903, “I / O” 0904, and “remote control” 0905. It consists of.
In this case, first, the copy / change program stored in advance in the storage device is expanded in the work area of the main memory, and the function setting information A and the function setting information B stored in the storage device are also read out to the main memory. Temporarily held in the data areas A and B of the memory. Then, the function setting information is copied / changed by the CPU executing the program. Specifically, for each setting content of the read function setting information A, the user selects whether to maintain or change the setting content, and copies the setting content of the function setting information A according to the selection to set the function. A process of changing the setting contents of the information B or maintaining the setting contents of the function setting information B is performed. The specific processing procedure is the same as in the first embodiment. Here, in order to change the function setting information of one user B by diverting the function setting information related to use of another user A related to the same function to the function setting information related to a specific function (for example, brightness value). It is necessary to specify the function of the function setting information related to the use of other user A. Therefore, a specific processing procedure for specifying the function will be described below.
In this case, for example, information related to a specific function in the function setting information is held in association with identification information for identifying the function. For example, if the function setting information related to the use of another user A is related to “brightness value”, “0100111011” indicating the setting content of the function setting information is identified and the function is a brightness value. For example, the identification information “01” is stored in association with each other. The function setting information may be further associated with identification information (for example, “001”) for identifying the user A.
Next, a processing procedure when one user B changes the function identification information related to his “brightness value” by using the information will be described. In accordance with the above-described example, first, the CPU constituting the function specifying input unit of the changing unit identifies the identification information “001” for identifying the user A and the identification information “Brightness value” for identifying the function “Brightness value”. The function identification information “01,0100111011” is read based on “01”, and the function setting information related to the brightness value of the user B is also read. The specification for reading out the function setting information relating to the brightness value of the user B is performed based on the identification information for identifying the user and the function as in the case of the user A described above. Then, the function setting information relating to the brightness value of the user A that has been read is copied, and the function setting information relating to the brightness value of the user B is overwritten with the information, whereby the function setting information of the user B is changed. Since the specific procedure for copying and changing in this case is the same as that in the first embodiment, description thereof is omitted.

  According to the configuration as described above, the functions to be copied and diverted are specified from the time of input. Therefore, the processing target of the copy / change is limited to the information related to the specified function, and the efficient copy / change is performed. Processing can be performed.

  <Process flow>

FIG. 10 is a diagram showing an example of the processing flow in the copy / change step. In this example, “input for specifying a function” is the same as the former in the above two meanings, that is, as described in the first embodiment. This is an input to specify the function to be changed when it is changed with the setting information, and the function setting information for other user's use stored in the storage device is once read into the main memory, and it is diverted from it This is the case of input to specify the function to be attempted.
The processing flow of the present embodiment is basically the same as the processing flow of the first embodiment shown in FIGS. However, as shown in the figure, in the accepting step S1003 for selecting the setting information of another person that he / she wants to use, the playback apparatus applies to other user's use for each setting content of the function setting information concerning other user's use. When the selection of the function setting information is received, the selection reception is performed based on an input for specifying the function. The input is performed based on, for example, the movement of the cursor and the pressing of the enter key for specifying the function displayed on the menu screen of the display.
The flow of processing in the remaining copy / change step is the same as the flow of processing in the copy / change step of the first embodiment, and the flow of the remaining processing is also the same as the flow of processing in the first embodiment. Description is omitted.

On the other hand, FIG. 11 is a diagram showing another example of the processing flow in the copy / change step. In this example, “input for specifying a function” specifies the function setting information relating to the latter of the above two meanings, that is, the function to be copied / changed first, and stores only that information. This is an input for reading from the apparatus and performing copy / change processing.
In this case, first, if it is determined in step S1101 whether or not to start work, it is determined that the work is to be started. In step S1102 for starting the copying / changing program, the reproduction apparatus stores the copy stored in the storage device.・ Launch the modified program in main memory.
Next, in step S1103 for accepting selection of setting information of another person that the user wants to use, the playback device selects function setting information related to the use of other users for each setting content of the function setting information related to the use of other users. Accept. This selection acceptance is executed by, for example, receiving a signal input from a remote controller through I / O. This signal is determined to maintain the current setting contents among the setting contents of the function setting information (that is, to reuse other person's setting information and copy it to change its own setting information) Is selected and input by key operation of the remote controller. The difference from the former example shown in FIG. 10 is that the input target is limited to that determined to maintain the current setting contents.
Next, in input receiving step S1104 for specifying a function to be copied and used, the playback apparatus receives a setting item selected based on the input. Then, in the “obtain function setting information of the function specified by input from the function setting information of the other person” step S1105, the playback apparatus performs such acquisition, and further, “updates own setting information with the acquired function setting information”. In step S1106, the playback apparatus performs such an update. The feature here is different from the former example described with reference to FIG. 10. Since the input accepted in step S1204 is specified to maintain the current setting contents from the beginning, the setting contents are maintained or changed. This is because it does not require such a determination step.
Further, in step S1107 for determining whether or not to end the process, if there are a plurality of selected setting items and a plurality of update processes are required, it is determined that the process is not to be ended. Alternatively, the processing after step S1104 is repeated. Then, when there is no longer any object to be processed, the playback apparatus determines that the process is to be ended and ends the process.

<Effect>
The reproduction apparatus of this embodiment limits the copy / change processing target to information relating to the specified function, and enables efficient copy / change processing.

<Overview>
The playback device of this embodiment is basically the same as the playback device of Embodiment 1 or 2, but the changing unit specifies the user usage immediately before the change as the function setting information of the user usage of the copy source copied by the copying means. It has a feature in that it has means to do.

<Configuration>
FIG. 12 is a diagram illustrating an example of functional blocks of the playback apparatus according to the present embodiment. The “reproducing apparatus” 1200 of this embodiment is basically the same as the reproducing apparatus of the first or second embodiment. However, the “change unit” 1203 further includes a “copy source specifying unit” 1207. Although not shown in the figure, the changing unit of the playback apparatus of this embodiment may further include “function specifying input means”.
The “copying source specifying unit” is configured to specify the user usage immediately before the change as function setting information for the user usage of the copy source to be copied by the copying unit.
Since the rest of the configuration is the same as that of the playback apparatus of the first or second embodiment, the description thereof is omitted.

  FIG. 13 is a schematic diagram illustrating an example of a hardware configuration of the playback apparatus according to the present embodiment. The hardware configuration of the playback device of this embodiment is basically the same as that of the playback device of the first or second embodiment. A specific configuration relating to copying / changing of the reproducing apparatus of this embodiment will be described below with reference to FIG. Here, an example in which the setting contents of another user A are copied to be the setting contents of one user B will be described.

  As shown in the figure, the changing unit of the playback apparatus of this embodiment includes a “storage device” 1301, a “main memory” 1302, a “CPU” 1303, an “I / O” 1304, and a “remote control” 1305. And a “display” 1306. The configuration is basically the same as the hardware configuration of the playback device of the first or second embodiment, but in this example, the function setting information immediately before the change is previously stored in the storage device as the change history related to the function setting information A. Has been. Then, the function setting information A immediately before the change is read together with the function setting information B and temporarily held in the data areas A and B of the main memory. Then, the function setting information is copied / changed by the CPU executing the program. The specific processing procedure is the same as that described in the first or second embodiment with reference to FIG.

  According to the configuration as described above, for example, when a plurality of users continuously view the same content on the same playback device, the function setting information to be copied and diverted is information related to user use immediately before the change. Therefore, it is not necessary to specify each copy / change processing target, and efficient copy / change processing can be performed. Specifically, for example, the user A views the content using the playback device by the playback function setting according to the function setting information A, and the user B subsequently follows the same content according to the same function setting information A. When the playback device is used for viewing using the playback function setting, the copy source specifying unit included in the change unit of the playback device specifies the function setting information A immediately before the change as the copy source, so that the function setting information A is displayed. By copying and overwriting the function setting information B, it is not necessary to specify each copy / change processing target.

<Process flow>
FIG. 14 is a diagram showing an example of the processing flow in the copy / change step. The process flow of this embodiment is basically the same as the process flow of the first or second embodiment shown in FIGS. However, as shown in the figure, in the change history reading step S1403, the playback apparatus reads the function setting information immediately before the change previously stored as the change history, and specifies the function setting information immediately before the change as the copy source. (Step S1404). Accordingly, in the subsequent processing steps, selection is accepted as function setting information relating to use by other users (step S1405), and is retained to maintain the setting contents (step S1409). The function setting information to be updated (step S1412) is the function setting information immediately before the change.
The flow of processing in the remaining copy / change step is the same as the flow of processing in the copy / change step of the first or second embodiment, and the flow of the remaining processing is the same as the flow of processing in the first or second embodiment. Therefore, the description is omitted.

<Effect>
With the playback device of this embodiment, for example, when a plurality of users continuously view the same content on the same playback device, the function setting information to be copied and diverted is information related to user usage immediately before the change. Since it has been specified from the beginning, it is not necessary to specify each copy / change process target, and efficient copy / change processing can be performed.

<Overview>
The playback apparatus according to the present embodiment is basically the same as any one of the playback apparatuses according to the first to third embodiments, but includes a change history holding unit that holds a change history of function setting information for each user. Is characterized in that it has a return changing means for executing the undo on the basis of the stored change history to return and change the stored function setting information.

<Configuration>
FIG. 15 is a diagram illustrating an example of functional blocks of the playback apparatus according to the present embodiment. The “reproducing apparatus” 1500 of this embodiment is basically in common with any one of the reproducing apparatuses according to the first to fourth embodiments. However, the playback apparatus according to the present embodiment further includes a “change history holding unit” 1508, and the “change unit” 1503 further includes a “return change unit” 1507. Although not shown in the figure, the changing unit of the playback apparatus of the present embodiment may further include at least one of “function specifying input means” and “copy source specifying means”.
The “change history holding unit” holds a change history of function setting information for each user. Further, the “return changing means” is configured to return and change the function setting information stored by executing undo based on the stored change history. There is no limit to the number of times of undoing, and it may be configured to return to a state in which processing has been performed multiple times before by repeating this multiple times. Furthermore, “Undo” here is not limited to canceling the processing executed immediately before and returning to the state before executing the processing, but going back to the state where the processing was performed several times at a time. Is also included.
The rest of the configuration is the same as the configuration of any one of the first to third embodiments, and a description thereof will be omitted.

Next, the significance of the configuration in which the change history is retained as in the present embodiment, and the function setting information stored by executing undo based on the change history is returned and changed will be described. In this regard, in the first embodiment or the like, typically, when changing the function setting information for one user (for example, B) by copying the function setting information for another user (for example, A), Since the function setting information is overwritten with that of A, the function setting information before the change of B is not saved, and cannot be reused. Therefore, if B wants to return the function setting information to the previous state, if there is no other user with the same function setting information, the setting is again performed by direct key input or the like.
However, for example, there may be a case where it is necessary to repeatedly use the function setting information for the same function setting alternately at regular intervals so that the volume value is changed between daytime and nighttime. It may be necessary to repeatedly use a part of the set contents (for example, daytime volume value) alternately while changing them alternately at regular intervals. In this case, when the information before the change is not saved due to overwriting, it is necessary to reset the setting by direct key input every time the change is made, which is inconvenient. Therefore, if function setting information before change is saved as a change history, copying and changing is performed using this information, so that the same complexity as described in the first embodiment can be reduced and setting operation can be performed. Time savings can be expected. Therefore, the reproducing apparatus of the present embodiment is configured to store the change history and to copy / change based on the change history.

  Next, a specific configuration for copying / changing the function setting information in the playback apparatus of the present embodiment will be described with a specific example. It should be noted that the function setting operation in this embodiment is also performed using a remote controller, and the example of such a remote controller is the same as that shown in FIG.

FIG. 16 shows an example of a screen display for performing such processing. In this example, a case where different volume values (MAX values) are set for each of the three time zones of morning, noon, and night will be described.
In this case, when an “automatic adjustment switching menu key” provided on the remote controller is pressed, an automatic adjustment switching main menu as shown in FIG. 16A is displayed. Then, by pressing the cursor key on the remote controller, the cursor is moved to the “volume value” position, “ON” is displayed, and the enter key is pressed. Then, the screen shown in FIG. 16B is displayed.

  Therefore, using this screen, input is performed by key operation of the remote controller, and the start / end times of each of morning, noon, and night, the MAX value of each volume value, and the like are set and changed. In the example shown in the figure, the start / end time is already in the morning “06: 00: 00-10: 00”, the daytime “10: 00-20: 00”, the night “20: 00-06: 0”, and the MAX value is “morning” 30 ", daytime" 60 ", night time" 25 ", and the like. In this case, when the function setting information is changed by overwriting as in the typical example of the first embodiment, for example, when the MAX value is set to “30” and then changed to “60”, “30” before the change is set. Since “30” is applied again, it is necessary to set this again one by one. In this example, after the morning MAX value is temporarily saved for one function setting menu, the daytime MAX value is stored. When the change is made, the morning MAX value before the change is held as the change history, so that it can be copied and used later. Similarly, when the daytime MAX value is stored and then changed to the nighttime MAX value, the daytime MAX value before the change is retained as the change history, and can be copied and used later. Become. As a result, once the morning, noon, and night MAX values are set once, they can be used alternately and repeatedly by a return change based on the change history relating to them. Further, when a part of the MAX value set as described above is changed, this can be realized by the same configuration. For example, even when the change of changing the daytime MAX value from “60” to “50” and then changing this value to “60” is repeated alternately, the information about the daytime MAX value is obtained for one function setting menu. Since it can be retained as a change history, it can be copied again and used later. A specific configuration for holding and using the above change history will be described later.

  When the settings for all the menus displayed in FIG. 16B are completed, the cursor is moved to the “setting complete” position at the lower left of the screen and the enter key is pressed to The processing operation related to the automatic adjustment switching is completed.

  In this case, for example, based on a clock built in the apparatus, the playback unit automatically switches the MAX value in a form of performing a return change based on the change history according to the set start time and end time. By performing reproduction with the reproduction function setting according to the function setting information, automatic adjustment of the volume value according to the time can be realized.

Next, the hardware configuration of the playback apparatus of this embodiment will be described. Also, a specific configuration related to retention and use of the change history will be described.
FIG. 17 is a schematic diagram illustrating an example of a hardware configuration of the playback apparatus according to the present embodiment. Since the hardware configuration of the playback apparatus of the present embodiment is basically the same as that described with reference to FIG. 5 for the first embodiment, description of common portions is omitted. However, in this embodiment, the “storage device” 1701 constituting the change unit stores a return change program for executing return based on the change history and returning the function setting information saved. .
Next, an example of a specific configuration related to retention and use of the change history will be described. In this example, the volume value (MAX value) “30” of “morning (06: 00: 00-10: 00)” and “daytime (10: 00-20: 00)” are the same as the example using FIG. 17 described above. An example in which the volume value (MAX value) “60” and the volume value (MAX value) “25” of “night (20: 00-06: 0)” are sequentially changed and repeatedly used will be described. .
For example, when the night MAX value is changed to the morning MAX value, the return change program is first expanded in the main memory based on an input including an instruction to execute an undo, and the morning change stored in the storage device The history and night function setting information are also read and temporarily stored in the main memory.

Then, the CPU changes the night function setting information back to the morning function setting information based on the morning change history, whereby the night MAX value is changed to the morning MAX value. This return change is realized, for example, by overwriting the night function setting information with the morning change history. The specific configuration for overwriting in this case is the same as the specific configuration for overwriting described in the first embodiment. It is. The changed night MAX value is retained as a change history. At that time, for example, the CPU determines the time using a built-in clock (not shown), and executes processing according to the time.
Note that when part of the function setting information once set for morning, noon, and night (for example, when changing the daytime MAX value from “60” to “50”), both processes are performed by the same process. By storing the data before the change as the change history, and copying and using the data, it becomes possible to use them repeatedly.

In addition, in the above, it is assumed that the function setting information before the change will be reused later from the beginning, as in the case of repeatedly using the function setting information set for morning, noon, and night. Although the case of saving has been described mainly in mind, the saving of the change history in the playback apparatus of the present embodiment includes a case where reuse is not assumed from the beginning. According to the above example, for example, since the next room of the apartment was vacant until then, the daytime volume value MAX value was set to “60”, but since the person moved into the next room, that value When only “50” was changed to “50”, the neighbor moved out at a later date, so that only the value may be changed to “60” again. In this case, according to the playback apparatus of the present embodiment, the setting information related to the MAX value “60” of the volume value is stored as the change history, so that it is not necessary to reset each time by diverting it. It will be over.
Further, according to the playback apparatus of this embodiment, for example, it is possible to repeatedly use function setting information set for viewing a program at a specific date and time. For example, if the brightness value is set to “8” only when watching a continuous drama “A” broadcast on the X channel from 21:00 to 22:00 every Tuesday, the function setting information includes the day of the week, time, and channel. By saving as an associated change history, no matter how the brightness value for viewing other programs is changed, when the drama “A” is viewed, the return change means of the change unit automatically Then, the brightness value is returned and changed to “8”, and the playback unit can play back based on the setting.
Furthermore, the change history holding period may be limited to a certain period, and the change history may be automatically deleted when the period elapses. For this reason, the change unit has a change history deletion means. You may do it. For example, in the case of the above-mentioned example, the retention period of the change history relating to the brightness value “8” when watching the continuous drama “A” broadcast on the X channel from 21:00 to 22:00 every Tuesday is set to one week. It is possible. In this case, for example, the change history saved on the first Tuesday of January is copied and saved on the second Tuesday of January, and at the same time, the change history of the first Tuesday of January is deleted. Brightness for the continuous drama “A” is repeated by repeating the process of copying and saving the change history copied and saved on the second Tuesday of the month and simultaneously deleting the change history of the second Tuesday of January. It is possible to hold the change history related to the value without duplication and perform reproduction using this.

<Process flow>
FIG. 18 is a diagram illustrating an example of a process flow related to retention of the change history in the process flow in the playback apparatus of the present embodiment. The processing flow of the present embodiment is basically the same as the processing flow of the first embodiment shown in FIGS. However, as shown in the figure, when the function setting information of itself is updated with the stored setting information (step S1810), the function setting information before the change is stored as a change history (step S1811).
Next, FIG. 19 is a diagram illustrating an example of a flow of processing related to the return change of the function setting information in the flow of processing in the playback apparatus of the present embodiment. Of the processing flow shown in the figure, steps S1901 to S1903 are common to the processing flow of the second embodiment shown in FIG. 14, and the change history stored in advance here is the step described in FIG. This is held by the processing in S1811. Then, in the undo execution step S1904, the playback apparatus executes undo based on the stored change history and changes the function setting information stored. In addition, as shown in the figure, the function setting information before update updated by the return change by executing undo may be further held as a change history (step S1905). As a result, the held function setting information before update is used as a change history in the process related to the next return change.
The remaining processing flow is the same as that of any one of the first to third embodiments, and thus the description thereof is omitted.

<Effect>
Even when it is necessary to repeatedly use both of the function setting information for the same function setting at regular intervals while the reproducing apparatus according to the present embodiment needs to repeatedly use both, both pieces of information are held as update information. Thus, by copying / changing using this information, it is possible to reduce complexity as in the first embodiment and save time required for the setting operation.
