After the content preservation information is stored in the content information server, family ID can be settled on the server system. For instance, users access a website on the server system, they select a family ID from the candidates to confirm a group for content sharing. Family ID is an identifier that can be applied to not only a family, but also friends, colleagues and other groups. When a device is registered in the system, the user can add its device name to the system. A name-resolving server runs in the cloud system and manages the table between the device ID and the device name. The correspondence between the device ID and the device name helps name resolving in the system, as needed. Content IDs may consist of two IDs that are a content ID and a sub-content ID. The sub-content ID is the identifier allocated globally in the content distribution market. The server in the cloud system can derive the content metadata from the sub-content ID. The derivation or reference operations between the sub-content ID and the content metadata will be conducted only on the server side.
Users may purchase new content on content distribution services, remove it from their devices, or update content saved on their devices. Therefore, users’ devices can request the content information server to add, delete and modify the content preservation information stored on the server. The tag <register_all> in Figure 7 shows the requested method on how to handle the content preservation information in the content information server after the server receives it. Each method request (register_all, register, delete, modify, clear_all) from content devices to the content server is described in 7.2.2, 7.2.3, 7.2.4 and 7.2.5.
7.2.2 Entire content information
Content devices can request the content information server to replace the current content preservation information saved on the server with the latest content preservation information. In that case, the content device sets the request method as <register_all> in content preservation information and sends it to the content information server. When receiving the content preservation information, the content information server deletes the users’ old content preservation information identified by user ID and newly adds the received and latest content preservation information. Therefore, when the method <register_all> is designated, all the content preservation information that is related with the device ID is removed once from the server.
7.2.3.2 Addition request to servers
When users purchase or get new content, it can be stored on their devices. In that case, the devices need to make a request to the content information server to add the preservation information of the newly saved content. The data format that the devices send to the server is given in Figure 8. An outline of an operating sequence is shown in Figure A.2.
