  The present invention relates to a content reproduction device, a display device, a content reproduction method, and the like.

  2. Description of the Related Art Conventionally, content playback apparatuses such as a DVD (Digital Versatile Disk) playback player and a music playback player have special playback functions such as fast-forwarding, rewinding, and skip movement for instantaneously moving the playback position in addition to the normal playback function. In recent years, a content reproduction apparatus can reproduce a plurality of contents, and a user can instruct normal reproduction or special reproduction of another content via a remote controller (hereinafter referred to as a remote controller) or the like. Along with the increase in the number of functions of such content playback devices, the number of operation keys provided in the remote control increases due to an increase in functions that can be designated by the user, and the user interface is complicated. For this reason, there is a problem that an instruction with the operation key is troublesome for a general user and the cost of the product is increased.

  Various techniques have been proposed for simplifying instructions such as special playback using operation keys of a remote controller for such a content playback apparatus. For example, in Patent Document 1, the up direction key is used for switching between the normal playback mode and various trick play modes, and the left direction key and the right direction key are also used for specifying parameters in various trick play modes.

A display unit 200 and a speaker 210 are connected to the content reproduction apparatus 100.

  The content storage unit 110 stores one or a plurality of content files. Each content file has reproduction data corresponding to one or a plurality of contents reproduced by the content reproduction apparatus 100. The content file includes data representing a moving image, data representing one or more still images, data representing sound, and the like. In the following description, a case will be described in which the content file is mainly data representing a moving image, and the content reproduction apparatus 100 reproduces the moving image. The function of the content storage unit 110 is realized by a storage medium such as a DVD that can be attached to and detached from the content reproduction apparatus 100, or a storage device such as a hard disk drive (Hard Disk Drive) apparatus. Note that the content storage unit 110 may be provided inside the content reproduction apparatus 100 or may be provided outside. When provided outside the content reproduction apparatus 100, a portable storage medium such as a USB memory can be used as the content storage unit 110.

  The operation input unit 120 receives user operation input via the operation panel 124 or the remote control 126. The operation panel 124 has a plurality of operation keys provided on the housing of the content reproduction apparatus 100, and based on an operation signal corresponding to the operation key operated by being pressed by the user, for example, Accept operation input. The remote controller 126 has a plurality of operation keys corresponding to the operation keys of the operation panel 124, and outputs a key code corresponding to the operation key operated by being pressed by the user, for example. The receiving unit 122 receives a key code from the remote controller 126 and accepts a user operation input via the remote controller 126. The operation panel 124 functions as an operation unit that receives user operation input. In addition, the remote controller 126 and the receiving unit 122 also function as an operation unit in the same manner as the operation panel 124.

  In the present embodiment, the normal playback mode and the special playback mode are designated by the user's operation input via the five operation keys (specifically, the up / down / left / right direction keys and the determination key) of the remote controller 126, and the desired Realization of content and playlist specification.

FIG. 2 shows an outline of a configuration example of the remote control 126 of FIG. FIG. 2 schematically illustrates the configuration of the remote controller 126 as viewed from above.
The remote control 126 has a power key POF, up / down / left / right direction keys UP, DN, LF, RT and an enter key CK as operation keys. The power key POF is an operation key for instructing to turn on or off the power of the content reproduction apparatus 100.

The down key DN (second operation key) is a direction key for instructing a down direction (a second direction opposite to the first direction). The left direction key LF (third operation key) is a direction key for designating the left direction (a third direction orthogonal to (intersecting with) the first direction). The right direction key RT (fourth operation key) is a direction key for instructing the right direction (fourth direction opposite to the third direction). Note that the remote controller 126 may include, for example, an operation key for volume adjustment in addition to the operation keys shown in FIG.

  The content playback apparatus 100 can play back content in a plurality of special playback modes in addition to the normal playback mode in which normal playback of content is performed. Here, the “special playback mode” is a mode in which special playback of content can be performed. In addition, “normal playback” refers to playback of content at a normal playback speed (movement speed) when the user views the content. On the other hand, “special playback” refers to playback of content in a playback mode different from normal playback, such as fast forward, rewind, and skip movement that instantaneously moves the playback position. The “playback mode” is a mode when content is played back. For example, in the present embodiment, fast forward, rewind, reverse playback, and the like are common in that “the content is played back in the forward or reverse direction at a playback speed different from normal playback”. The form is assumed to be the same reproduction mode (trick play). In this embodiment, trick play and skip movement are different playback modes. In the following description, the playback speed when playing in the reverse direction is represented by using the sign “-” (for example, the playback speed of normal playback is set to “1 ×” and the playback speed in the reverse direction is set to 1 ×. The movement speed when performing the above is “−1 times”). Furthermore, in the special playback mode, it is possible to move within the content, but the degree of movement in one mode or within a certain time in a certain mode is defined as a “movement unit”. For example, in the special playback mode corresponding to the double-speed fast-forward playback, the playback speed “2 ×” is the moving unit. In the special playback mode corresponding to the skip movement of 15 seconds, the movement amount “15 seconds” is the movement unit. In this way, the movement amount or movement speed in the content in each special playback mode is used as a movement unit. In particular, the movement unit in the special reproduction mode is referred to as “special reproduction unit”.

  In the present embodiment, it is assumed that two or more special playback modes having the same playback mode and different movement units are included in the plurality of special playback modes. Specifically, in the present embodiment, the special playback mode corresponding to 30-second skip movement and the special playback mode corresponding to 15-second skip movement are distinguished from each other as different special playback modes. On the other hand, in this embodiment, if the playback mode is trick play, the same special playback mode (trick play mode) is assumed regardless of the speed of movement. Specifically, in this embodiment, both the double-speed fast-forward playback and the quad-speed fast-forward playback are included in the trick play mode. At this time, the up key UP and the down key DN have a function of selecting and determining one of a plurality of special reproduction modes arranged in descending or ascending order of the moving amount or moving speed.

  In the present embodiment, a content movement mode and a playlist movement mode are defined as modes other than the normal reproduction mode and the special reproduction mode. Then, the up key UP and the down key DN are combined with a function of selecting one of the content movement mode and the playlist movement mode in addition to the plurality of special reproduction modes. In the content movement mode, movement from one content to another content (movement between contents) is performed, and in the playlist movement mode, movement from one content group (playlist) to another content group ( Move between playlists). Here, in the content movement mode, one or more contents can be set as a movement unit. In the playlist movement mode, one or two or more playlists can be set as a movement unit.

Further, in the present embodiment, the left direction key LF and the right direction key RT are also used as a function of selecting and determining the execution direction (reproduction direction) of the special reproduction mode determined as described above.
Furthermore, in the present embodiment, the left direction key LF and the right direction key RT are combined with the function of selecting one of the contents in the content movement mode or one of the playlists in the playlist movement mode.
Furthermore, the determination key CK is also used as a function for determining the selected content or playlist.
In a predetermined special playback mode such as trick play or slow playback, which will be described later, the function of selecting and determining the moving amount or moving speed in the content with the left direction key LF and the right direction key RT is also used.

FIG. 3 is an explanatory diagram of modes of the content reproduction apparatus 100 in the present embodiment.
The modes of the content playback apparatus 100 in this embodiment are broadly classified into a playlist movement mode, a content movement mode, a chapter movement mode, a scene movement mode, a skip movement mode, a trick play mode, a slow playback mode, and a stop mode. Of these modes, the chapter movement mode, scene movement mode, skip movement mode, trick play mode, and slow reproduction mode correspond to the special reproduction mode. In each of the above modes, the movement units to be selected by one operation input are different from each other. If it is considered that the normal playback mode is 1 × speed trick play, the normal play mode may be included in the trick play mode of FIG. 3. In FIG. 3, hierarchies are made so that the movement unit becomes smaller in the order of playlist movement mode, content movement mode, chapter movement mode, scene movement mode, skip movement mode, trick play mode, slow playback mode, and stop mode. Yes.

In the playlist movement mode, movement from one playlist to another playlist is performed. That is, the movement unit to be selected in the playlist movement mode is “playlist”. The playlist is composed of a plurality of contents.
In the content movement mode, movement from one content to another is performed. The movement unit to be selected in the content movement mode is “content”. The content is composed of a plurality of chapters or scenes.
In the chapter movement mode, movement from one chapter to another is performed. That is, the movement unit to be selected in the chapter movement mode is “chapter”. Note that a plurality of chapters are provided in one content based on preset chapter information.
In the scene movement mode, movement from one scene to another scene is performed. The movement unit to be selected in the scene movement mode is “scene”. A plurality of scenes are provided in one content.
In the skip movement mode, the content moves instantaneously from the current reproduction time to another reproduction time for a specified time within one content. That is, the movement unit to be selected in the skip movement mode is “specified time”. In the present embodiment, as a plurality of skip movement modes having different designated times, a skip 30-second movement mode (first special reproduction mode) and a skip 15-second movement mode (second special reproduction mode) are provided. Here, the skip 30-second movement mode and the skip 15-second movement mode have the same content reproduction mode and different movement amounts or movement speeds in the content. The skip 30-second movement mode is a first skip movement mode corresponding to the first movement amount (30 seconds). On the other hand, the skip 15-second movement mode is a second skip movement mode corresponding to a second movement amount (15 seconds) different from the first movement amount.
In the trick play mode, trick play (fast forward, fast reverse, reverse playback, etc.) is performed. The execution direction and speed of the trick play mode can be changed by the left direction key LF and the right direction key RT.
In the slow playback mode, slow playback (slow playback in the forward direction, slow playback in the reverse direction) is performed. The execution direction and speed of the slow playback mode can be changed by the left key LF and the right key RT.
In the stop mode, the content reproduction and the content reproduction stop are repeated.

Each time an operation input is performed with the down key DN, the mode is switched to a mode in which the movement unit is small. Specifically, each time an operation is input with the down key DN, the mode is switched to a mode in which the moving amount in the content is small or the moving speed in the content is slow. When an operation input with the down key DN is performed while the playlist movement mode with the largest movement unit is selected, the content movement mode and the chapter movement mode are switched in this order. In this way, every time an operation input is made with the down key DN, the mode is switched to a mode in which the movement unit is small (small) by one step.

The left direction key LF has a function of switching the execution direction to the past direction (reverse direction, the direction opposite to the content reproduction direction) in the current special reproduction unit in addition to the function of the known left direction key.
The right direction key RT has a function of switching the execution direction to the future direction (forward direction, content reproduction direction) in the current special reproduction unit in addition to the function of the known right direction key.

  The determination key CK determines the reproduction target content from the playlist list or the content list in addition to the function of the known determination key. Further, the enter key CK is an operation key for instructing a pause during reproduction and for instructing a reproduction during the stop or pause.
