Information processing apparatus, music distribution system, music distribution method and computer program
First Claim
1. An information processing apparatus for playing back music data, connected to a distribution server for distributing music data over a network, comprising:
- a music storage portion to store music data;
a music playback portion to play back music data;
a metadata acquisition portion to acquire metadata describing information about music data being played back in the music playback portion;
a metadata transmission portion to transmit the metadata acquired in the metadata acquisition portion to the distribution server;
a music reception portion to receive distributed music data selected in the distribution server based on the information contained in the metadata and distributed from the distribution server;
a music acquisition portion to acquire local music data from the music storage portion based on the information contained in the metadata, the local music data acquired from the music storage portion being different than the distributed music data distributed from the distribution server; and
a control portion to control the music playback portion to selectively play back the distributed music data distributed from the distribution server and the local music data acquired from the music storage portion by the music acquisition portion based on a configurable playback ratio, wherein the configurable playback ratio specifies a ratio between the distributed music data distributed from the distribution server and the local music data acquired from the music storage portion and, wherein the configurable playback ratio is used by the control portion to select either the distributed music data or the local music data for play back by the music playback portion.

5. An information processing apparatus for playing back content data, connected to another information processing apparatus over a network, comprising:
-
a content storage portion to store content data; a content playback portion to play back content data; a metadata acquisition portion to acquire metadata describing information about content data being played back in the content playback portion; a metadata transmission portion to transmit the metadata acquired in the metadata acquisition portion to the other information processing apparatus; a content reception portion to receive distributed content data selected in the other information processing apparatus based on the information contained in the metadata and transmitted from the other information processing apparatus; a content acquisition portion to acquire local content data from the content storage portion based on the information contained in the metadata, the local content data acquired from the content storage portion being different than the distributed music data transmitted from the other information processing apparatus; and a control portion to control the content playback portion to selectively play back the distributed content data transmitted from the other information processing apparatus and the local content data acquired from the content storage portion by the content acquisition portion based on a configurable playback ratio, wherein the configurable playback ratio specifies a ratio between the distributed content data transmitted from the other information processing apparatus and the local content data acquired from the content storage portion and, wherein the configurable playback ratio is used by the control portion to select either the distributed content data or the local content data for play back by the music playback portion.

13. A non-transitory computer-readable medium storing a computer program for playing back music in a computer connected to a distribution server for distributing music over a network, the computer program causing the computer to execute a process comprising the steps of:
-
storing music data; playing back music data; acquiring metadata describing information about the music being played back in the playback step; transmitting the metadata acquired in the metadata acquiring step to the distribution server; receiving distributed music selected in the distribution server based on the information contained in the metadata and distributed from the distribution server; acquiring local music data from the music data stored in the storing step based on the information contained in the metadata, the local music data acquired from the music data being different that the distributed music received from the distribution server; and controlling music playback to selectively play back the distributed music data distributed from the distribution server and the local music data acquired in the music acquiring step based on a configurable playback ratio, wherein the configurable playback ratio specifies a ratio between the distributed music data distributed from the distribution server and the local music data acquired from the music storage portion and, wherein the step of controlling music playback further includes using the configurable playback ratio to select either the distributed music data or the local music data for play back by the computer.
