A communication system and so forth are provided by which registration or cancellation of a plurality of apparatus owned by a user can be executed efficiently. In the communication system, a content processing apparatus acquires a second source ID list of a content reproduction apparatus. If it is detected based on the second source ID list that the content reproduction apparatus is not yet registered in a management server and a recorder ID of the content processing apparatus is not yet registered in the second source ID list, the content processing apparatus recommends registration. If a registration instruction of the content reproduction apparatus is accepted, the content processing apparatus requests the management server to register the content reproduction apparatus. The content processing apparatus receives registration completion transmitted from the management server and adds a group ID stored in a first source ID list to the second source ID list of the content reproduction apparatus. If the registration instruction of the content reproduction apparatus into the management server is not accepted, then the content processing apparatus adds the recorder ID of the content processing apparatus to the second source ID list.

The invention claimed is: 1. A communication system, comprising:a content processing apparatus for recording and/or reproducing content data,a content reproduction apparatus for reproducing at least the content data, anda management server for managing said content processing apparatus and said content reproduction apparatus,wherein said content processing apparatus includes a processing unit and a computer-readable storage medium encoded with computer executable instructions, the instructions, when executed by the processing unit, causes the processing unit to perform the steps of:storing a group ID in a first source ID list;acquiring a second source ID list stored in said content reproduction apparatus from said content reproduction apparatus;detecting, based on said second source ID list acquired by said acquiring step, whether said content reproduction apparatus is registered in said management server and detecting whether a recorder ID is included in said acquired second source ID list, wherein the recorder ID is used to identify whether said content processing apparatus produced the content data;outputting notification information for a recommendation of a registration into said management server when it is detected by said detecting step that said content reproduction apparatus is not registered in said management server and that the recorder ID corresponding to said content processing apparatus is not included in said second source ID list;transmitting, when a registration instruction of said content reproduction apparatus into said management server is accepted, registration request information for requesting for the registration of said content reproduction apparatus to said management server;receiving registration completion information representative of a completion of the registration transmitted as a response to the registration request information from said management server;adding, upon a reception of the registration completion information, the group ID stored in said first source ID list to said acquired second source ID list;adding, when the registration instruction of said content reproduction apparatus into said management server is not accepted, the recorder ID corresponding to said content processing apparatus to said acquired second source ID list; andtransmitting the updated second source ID list to said content reproduction apparatus;said management server includes a processing unit and a computer-readable storage medium encoded with computer executable instructions, when executed by the processing unit of said management server, causes the processing unit of said management server to perform the steps of:registering said content reproduction apparatus into a registration record to the user in response to the registration request information; andtransmitting the registration completion information representative of the completion of the registration to said content processing apparatus; andsaid content reproduction apparatus includes a processing unit and a computer-readable storage medium encoded with computer executable instructions, when executed by the processing unit of said content reproduction apparatus, causes the processing unit of said content reproduction apparatus to perform the steps of:receiving the content data wherein the content data includes a source ID;receiving the updated second source ID list from said content processing apparatus;receiving a reproduction request to reproduce the content data;upon receiving the reproduction request, controlling the reproduction of the content data based on the received second source ID list.
