Description

  The present invention relates to an information processing apparatus, an information processing method, a recording medium, and a program, and in particular, an information processing apparatus capable of presenting content in a manner that is easier for a user to understand by using a chapter set for the content, and The present invention relates to an information processing method, a recording medium, and a program.

For example, content data such as movies and video clips distributed using a recording medium such as a DVD or distributed via a network such as the Internet has a specific cue point called a chapter. Has been. For example, in the case of a movie, a chapter is the start of a scene of interest or a point of a story break, and is set to a point representing a break of a video or a song like a track in a CD or the like. For content such as movies and video clips, several points in one title (for example, one movie, one video clip for an album, etc.), a breakpoint that the seller wants to be able to cue at the top of the work For example, chapters are set in advance and sold at the transition of scenes for movies and at the breaks of songs for video clips. In a playback device that plays back content data, a comment or thumbnail image corresponding to a chapter is displayed as a chapter menu, and the user selects one of them to start playback from the corresponding chapter position. May be provided on the screen (see, for example, Patent Document 1).
JP-A-11-69284

  Also, when a chapter is not set in the content, such as when a broadcast program is recorded, for example, the chapter can be set at a desired position by a user operation input, or a scene change is detected and automatically In addition, a technique that can set a chapter automatically or can automatically set a chapter at every predetermined time interval is also widely used.

  By selecting a desired chapter in the content, the user can reproduce a desired portion in the content. For example, by reproducing a little from each chapter set in the content, the entire content can be reproduced. Instead of viewing everything from the beginning of the content in order to understand the content of the content to a certain extent in a short time or searching for a desired location in the content, use the chapter to play from the desired position in the middle of the content It can be made to start.

  With reference to FIG. 1, for example, in content data in which eight chapters are set, a user tries to find a scene 1 recorded between chapter 5 and chapter 6 and at a position close to chapter 6. The case will be described.

  As described above, when a user desires to reproduce a certain part in the content, it is possible to select a desired chapter in the content and start reproduction from the chapter position. For example, as shown in FIG. 1A, when a user tries to search for a desired scene by reproducing only a relatively short time in order from chapter 0, the scene to be searched is shown in FIG. If the playback time from each chapter is short when it is recorded at a time close to the next chapter, as in scene 1 of Fig. 1, there is a high possibility that the desired scene will be overlooked, and the playback time from each chapter will be increased. If it is long, the possibility of finding a desired scene increases, but the possibility that the time taken to find the desired scene will also increase.

  Therefore, consider a case where the user selects any chapter instead of from the beginning of the content, starts playback from there, and tries to find a desired scene. There is no desired scene between the selected chapter and the next chapter, and as shown in FIG. 1B, the chapter 3 is selected, and playback is continued from there, between the chapter 5 and the chapter 6. When scene 1 is found, the user can recognize the playback time from chapter 3 to the desired scene, and is unaware that it has passed through another chapter during playback. If the desired part is found and trying to return to the starting point of that part, the user does not know from which chapter the playback should start. That is, the conventional content reproduction apparatus only uses the chapter as a reproduction start point.

  Further, even when the user sets chapters before and after scene 1 in FIG. 1 in order to repeatedly reproduce only a desired scene divided by chapters, the conventional chapter is used as a playback start point. Since it can only be specified, after the chapter set as the start point of scene 1 is selected and playback is started, playback is stopped when scene 1 ends, and the playback start point chapter is selected again and played back. I had to make an operation input to instruct.

  It is required to present the content without causing the user to perform complicated operations so that the chapters set in the content can be used effectively so that the user can respond to various requests for content usage. Yes.
