GROUP ADMISSION SYSTEM AND SERVER AND CLIENT THEREFOR

摘要

Disclosed is a group admission system (1) having a client (200e-200g) and a server (100a-100d) that belongs to a closed group within which contents are available. The client (200e-200g) determines whether it is permissible to request to join the group to be a member device thereof based on the number of groups that the client (200e- 200g) is permitted to be in. If permissible, the client (200e-200g) transmits a registration request to the server (100a-100d) with information unique to the client (200e-200g). The server (100a-100d) determines whether to permit the client (200e-200g) to join the group by registering with the server (100a-100d) based on the number of member devices registered with the server (100a-100d) and the maximum number of member devices registerable with the server (100a-100d). If it is permitted, the server (100a-100d) registers the unique information, and transmits group identification information to the client (200e-200g). The client receives and stores the group identification information.
