Abstract

A communication system is disclosed which includes: a storing element for storing content data corresponding to an image associated with a distributed storage medium; a retrieving element for retrieving address information on a network from the distributed storage medium; an accessing element for accessing the storing element based on the address information retrieved by the retrieving element; and a recording element for recording to the distributed storage medium the content data acquired by the accessing element from the storing element.

Claims

1. A first communication apparatus comprising:

storing means separate from an optical disc for storing optical disc identification data for identifying the optical disc and content data in association with the optical disc identification data, the content data comprising audio data, video data and/or game data associated with said optical disc;

receiving means for receiving the optical disc identification data held on said optical disc, said optical disc identification data being transmitted from a second communication apparatus based on an address retained on said optical disc, wherein the second communication apparatus is at a same location as a location of the optical disc;

judging means for making a judgment whether said optical disc is legitimate based on said optical disc identification data received by said receiving means;

searching means for searching through said storing means for the content data corresponding to said optical disc based on said optical disc identification data;

transmitting means for transmitting said content data to said second communication apparatus in accordance with the judgment by said judging means;

wherein said optical disc identification data is image data;

retrieving means for retrieving information about an address on a network and storage medium identification data for identifying said optical disc, from said optical disc which stores the address information and said storage medium identification data and which has a recording area on which content data comprising audio data, video data and/or game data are to be recorded;

judging means for making a judgment whether said optical disc is legitimate based on said storage medium identification data retrieved by said retrieving means;

recording means which, based on said address information retrieved by said retrieving means, accesses said second communication apparatus which stores the content data comprising audio data, video data and/or game data corresponding to said optical disc, said recording means further recording on said recording area of said optical disc the content data transmitted from said second communication apparatus, wherein the recording means is at a same location as a location of the optical disc;

controlling means for controlling said recording means in accordance with the judgment,

wherein said recording means further comprises;

accessing means which, based on said address information retrieved by said retrieving means, accesses said second communication apparatus which stores the content data corresponding to optical disc; and

downloading means for recording to said recording area of said optical disc the content data transmitted from said second communication apparatus; and

wherein said controlling means inhibits access to said second communication apparatus by said accessing means depending on the judgment by said judging means.

2. A first communication apparatus according to claim 1, wherein said judging means judges whether said optical disc is legitimate based on whether said optical disc identification data received by said receiving means is stored in said storing means.

3. A first communication apparatus according to claim 1, wherein said optical disc identification data is provided corresponding to each content data item recorded on said optical disc.

4. A first communication apparatus according to claim 1, wherein said content data stored in said storing means is kept up to date.

5. A first communication apparatus according to claim 1, wherein said content data stored in said storing means is furnished with supplementary data.

6. A first communication apparatus according to claim 1, wherein said content data stored in said storing means is compressed data.

7. A first communication apparatus according to claim 1, wherein said content data stored in said storing means may be downloaded by said second communication apparatus during a specific time period.

8. A first communication apparatus according to claim 1, wherein said content data stored in said storing means may be downloaded by said second communication apparatus a predetermined number of times.

9. A first communication apparatus according to claim 1, wherein said searching means searches through said storing means for the content data in accordance with selection data transmitted from said second communication apparatus.

10. A first communication apparatus comprising:

a storing unit for storing a plurality of track data items comprising audio data, video data and/or game data corresponding to a distributed disc and disc identification data for identifying a legitimate disc, in association with said plurality of data track items;

a receiving unit for receiving said disc identification data that is held on said disc and that is transmitted from a second communication apparatus at a same location as a location of said disc;

a judging unit for making a judgment whether said disc is a legitimate disc based on said disc identification data received by said receiving unit;

a searching unit for searching through said storing unit for said plurality of track data items corresponding to said disc identification data;

a transmitting unit for transmitting to said second communication apparatus said plurality of track data items retrieved by said searching unit in accordance with the judgment by said judging unit;

a retrieving unit for retrieving information about an address on a network at which a plurality of track data items comprising audio data, video data and/or game data are stored corresponding to said distributed disc, and disc identification data for identifying said disc, from said recording medium which stores the address information and said disc identification data and which has a recording area on which said plurality of track data items comprising audio data, video data and/or game data are to be recorded upon receipt;

a judging unit for making a judgment whether said disc is a legitimate one based on said disc identification data retrieved by said retrieving unit;

an accessing unit which, based on said address information retrieved by said retrieving unit, accesses said second communication apparatus which stores said plurality of track data items comprising audio data, video data and/or game data;

a recording unit for recording on said recording area of said disc said plurality of track data items transmitted from said second communication apparatus, wherein the recording unit is located at a same location as a location of said disc; and

a controller for inhibiting access by said accessing unit depending on the judgment by said judging unit.
