It is a figure which shows an example of carrying out and reproduction | regeneration of a part of content which concerns on embodiment. It is a figure which shows an example of the content search using the tag information which concerns on embodiment.

  FIG. 1 is a diagram illustrating an example of a schematic configuration of a content processing system according to the embodiment. As shown in FIG. 1, the content processing system includes a communication terminal 1, a content processing device 2, a tag list server 3, and the like.

  The communication terminal 1 can receive input of keywords, detect keywords from various data, and register (store) these keywords. For example, one or more keywords of interest on Twitter or FaceBook, or one or more keywords used for site search can be registered. The content processing device 2 receives one or more keywords transmitted from the communication terminal 1, and searches one or more contents managed by the content processing device 2 for one or more contents corresponding to the received one or more keywords. Then, the retrieved one or more contents or a part of the retrieved one or more contents is transmitted to the communication terminal 1. Thereby, the communication terminal 1 can receive one or more contents or a part of one or more contents corresponding to one or more keywords, and reproduce the received one or more contents or a part of one or more contents. it can. For example, the content processing apparatus 2 can transmit a content stream or a partial content stream to the communication terminal 1, and the communication terminal 1 can stream and reproduce the content or a part of the content.

  For example, the content managed by the content processing device 2 has meta information (content ID, title, performer information, explanation, etc.). When the communication terminal 1 designates a content search including all keywords (AND search), the content processing device 2 searches for one or more contents having meta information including all received keywords. Thereby, the communication terminal 1 receives one or more contents or a part of one or more contents having meta information including all keywords, and reproduces the received one or more contents or a part of one or more contents. Can do. When the communication terminal 1 specifies a content search (OR search) including at least one of all keywords, the content processing apparatus 2 has meta information including at least one of all received keywords. Search for one or more contents. Thereby, the communication terminal 1 receives one or more contents or a part of one or more contents having meta information including at least one keyword, and reproduces the received one or more contents or a part of one or more contents. can do.

  In addition, tag information may be associated with content managed by the content processing apparatus 2. When the communication terminal 1 specifies content search (AND search) including all keywords, the content processing device 2 searches for one or more contents associated with tag information including all received keywords.

You can also. The user of the content storage device 2a can specify the tag information included in the tag list a via the content storage device 2a, and the content storage device 2a is specified corresponding to the specification of the tag information. Based on the tag information, the content A is reproduced from the beginning of the predetermined scene, and when the tag information includes a comment, this comment is also reproduced (displayed). The content storage device 2 a transmits the tag list “a” of the content A to the tag list server 3.

  In addition, for example, the user of the content storage device 2b first passes the content storage device 2b through the content storage device 2b to the first scene that the content A stored by the content storage device 2b likes (for example, a position 15 minutes from the beginning). A cue point can be set, a second cue point can be set in the second scene (for example, a position 45 minutes from the beginning) of the content A, and the first and second cue points by the user can be set. In response to the setting operation, the content storage device 2b creates a tag list b including first and second tag information corresponding to the first and second cue points. For example, the tag list b includes the ID of the content A, the first tag information is the first position information (position information for 15 minutes from the top of the content A), and the first tag information is the first information Comments can also be included, the second tag information can include second position information (position information for 45 minutes from the beginning of the content A), and the second tag information can also include a second comment or the like. it can. The user of the content storage device 2b can specify the first tag information included in the tag list b via the content storage device 2b, and the content storage corresponding to the specification of the first tag information. The device 2b reproduces the content A from the beginning of the first scene based on the designated first tag information, and also reproduces (displays) the comment when the first tag information includes a comment. . Similarly, the user of the content storage device 2b can specify the second tag information included in the tag list b via the content storage device 2b, and in response to the specification of the second tag information.
