Abstract

The present invention relates to an information processing apparatus for controlling content reproduction on a basis of a first weight set to a playlist of contents and indicating a priority of the playlist and a second weight set to each of contents registered in playlists and indicating a priority of the content. The information processing apparatus includes a weight setting unit for, when a plurality of playlists are selected, updating a first weight set to each of the plurality of selected playlists and updating a second weight set to each of contents registered in the plurality of selected playlists according to one of a number of playlists in which each of the contents is registered and a specified reproduction method, and a reproduction controlling unit for controlling random content reproduction on a basis of the first weight and the second weight set by the weight setting unit.

Claims

1. An information processing apparatus for controlling content reproduction on a basis of a first weight set to a playlist of contents and indicating a priority of the playlist and a second weight set to each of contents registered in playlists and indicating a priority of the content, said information processing apparatus comprising:

a weight setting unit for, when a plurality of playlists are selected, updating said first weight set to each of the plurality of selected said playlists and updating said second weight set to each of contents registered in the plurality of selected said playlists according to one of a number of playlists in which each of the contents is registered and a specified reproduction method; and

a reproduction controlling unit for controlling random content reproduction on a basis of said first weight and said second weight set by said weight setting unit.

2. The information processing apparatus as claimed in claim 1,

wherein when an instruction to perform, as said reproduction method, random reproduction using a sum of sets of contents registered in the plurality of selected said playlists is given, said weight setting unit updates said second weights set to all the contents registered in the plurality of selected said playlists.

3. The information processing apparatus as claimed in claim 1,

wherein when an instruction to perform, as said reproduction method, random reproduction using contents registered duplicately in the plurality of selected said playlists is given, said weight setting unit updates said second weights set to the contents registered duplicately in the plurality of selected said playlists.

4. The information processing apparatus as claimed in claim 1,

wherein when an instruction to update a weight of a content being reproduced is given by control of said reproduction controlling unit, said weight setting unit updates said first weights set to playlists in which said content being reproduced is registered so as to effect one of an increase and a decrease in said first weights according to a content of the instruction, and also updates weights of other contents registered in the playlists in which said content being reproduced is registered on a basis of the updated said first weights.

5. An information processing method of an information processing apparatus for controlling content reproduction on a basis of a first weight set to a playlist of contents and indicating a priority of the playlist and a second weight set to each of contents registered in playlists and indicating a priority of the content, said information processing method comprising:

a weight setting step of, when a plurality of playlists are selected, updating said first weight set to each of the plurality of selected said playlists and updating said second weight set to each of contents registered in the plurality of selected said playlists according to one of a number of playlists in which each of the contents is registered and a specified reproduction method; and

a reproduction controlling step of controlling random content reproduction on a basis of said first weight and said second weight set by a process of said weight setting step.

6. A program for making a computer perform a process for controlling content reproduction on a basis of a first weight set to a playlist of contents and indicating a priority of the playlist and a second weight set to each of contents registered in playlists and indicating a priority of the content, said program comprising:

a weight setting step of, when a plurality of playlists are selected, updating said first weight set to each of the plurality of selected said playlists and updating said second weight set to each of contents registered in the plurality of selected said playlists according to one of a number of playlists in which each of the contents is registered and a specified reproduction method; and

a reproduction controlling step of controlling random content reproduction on a basis of said first weight and said second weight set by a process of said weight setting step.

7. An information processing means for controlling content reproduction on a basis of a first weight set to a playlist of contents and indicating a priority of the playlist and a second weight set to each of contents registered in playlists and indicating a priority of the content, said information processing apparatus comprising:

a weight setting means for, when a plurality of playlists are selected, updating said first weight set to each of the plurality of selected said playlists and updating said second weight set to each of contents registered in the plurality of selected said playlists according to one of a number of playlists in which each of the contents is registered and a specified reproduction method; and

a reproduction controlling means for controlling random content reproduction on a basis of said first weight and said second weight set by said weight setting means.
