Information processing system that manages stored content using playlists
A system allows a user to integrally manage content regardless whether the content is owned or not owned by the user. In a reproduction terminal, one piece of sort-out information is generated from one play list. Sort-out information is obtained by classifying the metadata of content registered with a play list into three types of metadata, search metadata, display metadata and processing metadata. The sort-out information generated in the reproduction terminal is transmitted to a reproduction terminal via a sort-out information server. In the reproduction terminal, a same play list as a play list of the reproduction terminal is created on the basis of the provided sort-out information. In the created play list, each piece of content registered with the play list is managed by making a distinction between the content owned by the user and the content not owned by the user.
1. A method for generating suggestions based upon a play list, the method comprising:
at an information generating apparatus:
storing a first play list including grouped content; and
generating information for use by an information processing apparatus in creating a second play list, said second playlist including some of the grouped content in the first play list, the information including metadata of the grouped content in the first play list, the generating means generating the information suggesting additional content related to the grouped content; and
at the information processing apparatus:
acquiring the information generated by the information generating apparatus; and
creating means for determining whether each piece of the grouped content or the metadata of the grouped content in the information acquired by the information processing apparatus is currently stored in the information processing apparatus, and creating the second play list including data indicating whether or not each piece of the additional content in the second play list is currently stored in the information processing apparatus or was previously stored in the information processing apparatus owned by the user and transferred to another device owned by the user.
2. An information processing system having an information generating apparatus and an information processing apparatus,
the information generating apparatus comprising:
storage means for storing a first play list including grouped content; and
generating means for generating information for use by the information processing apparatus in creating a second play list, said second playlist including some of the grouped content in the first play list, the information including metadata of the grouped content in the first play list, the generating means generating the information suggesting additional content related to the grouped content,
the information processing apparatus comprising:
acquiring means for acquiring the information generated by the information generating apparatus; and
creating means for determining whether each piece of the grouped content or the metadata of the grouped content in the information acquired by the acquiring means is currently stored in the information processing apparatus, and creating the second play list including data indicating whether or not each piece of the additional content in the second play list is currently stored in the information processing apparatus or was previously stored in the information processing apparatus owned by the user and transferred to another device owned by the user.
3. A non-transient computer readable recording medium including computer executable instructions, wherein the instructions, when executed by a processor, cause the processor to perform a method for generating suggestions based upon a play list, the method comprising:
at an information generating apparatus:
storing a first play list including grouped content; and
generating information for use by an information processing apparatus in creating a second play list, said second playlist including some of the grouped content in the first play list, the information including metadata of the grouped content in the first play list, the generating means generating the information suggesting additional content related to the grouped content; and
at the information processing apparatus:
acquiring the information generated by the information generating apparatus; and
creating means for determining whether each piece of the grouped content or the metadata of the grouped content in the information acquired by the information processing apparatus is currently stored in the information processing apparatus, and creating the second play list including data indicating whether or not each piece of the additional content in the second play list is currently stored in the information processing apparatus or was previously stored in the information processing apparatus owned by the user and transferred to another device owned by the user.
