Abstract

A playback apparatus that communicates with a server and plays back data of a content item in accordance with a control file sent from the server includes a medium-information obtaining unit that obtains medium specifying information specifying a recording medium inserted into the medium-information obtaining unit; a playback-mode specifying unit that specifies a playback mode of a content item recorded on the recording medium; a sending unit that sends the medium specifying information and information specifying the playback mode to the server; and a playback control unit that receives a control file sent by the server in accordance with the sent medium specifying information and the sent information specifying the playback mode and controls playback of the content item recorded on the recording medium in accordance with the control file.

Claims

1. A playback method for playing back data of a content item recorded on a recording medium in accordance with a control file sent from a server through communication, the playback method comprising the steps of:

obtaining medium specifying information specifying the recording medium;

specifying a playback mode of a content item recorded on the recording medium;

sending the medium specifying information and information specifying the playback mode to the server; and

receiving a control file sent by the server in accordance with the sent medium specifying information and the sent information specifying the playback mode and controlling playback of the content item recorded on the recording medium in accordance with the control file.

2. The playback method according to claim 1,

wherein a plurality of content items for introducing products or services are recorded on the recording medium, and

playback of the content items is controlled in a predetermined playback order or at a predetermined playback position in accordance with the control file sent from the server.

3. The playback method according to claim 2, further comprising the step of:

sending information specifying a product or a service for which an order is placed, to the server through a network in accordance with a user command.

4. The playback method according to claim 3,

wherein a control file generated in accordance with a purchase history of a user regarding the products and services is received from the server, the user being associated with the medium specifying information, and playback of the content items recorded on the recording medium is controlled in accordance with the control file.

5. A playback apparatus that communicates with a server and plays back data of a content item in accordance with a control file sent from the server, the playback apparatus comprising:

medium-information obtaining means for obtaining medium specifying information specifying a recording medium inserted into the medium-information obtaining means;

playback-mode specifying means for specifying a playback mode of a content item recorded on the recording medium;
