摘要:
New devices (101) are added to an existing domain by obtaining domain information (e.g., domain name and private domain password) from devices (101) already in the domain that preferably are in close proximity. Once the domain information has been transferred from the device already in the domain to the device being added to the domain, the device being added to the domain contacts a key issuer (105) to complete its registration into the domain. The key issuer returns a DRM domain private key (206) as well as a DRM certificate (202). Both are utilized by the device to obtain and render digital content (204).
