Abstract
A method and an apparatus for managing domains are provided. The method of managing one or more domains performed by a domain manager located in a home network includes determining whether to register a first device located in the home network to a domain, and providing data required to share content between the first device and a second device registered to the domain according to the determination. In the method and apparatus, content can be shared by connecting the devices with one another including a user, and the burden of content providers for management can be reduced.

A method of registering a device with a domain, the method comprising:
- requesting domain information to a domain information providing unit of a domain manager;
- receiving the domain information from the domain information providing unit;
- requesting registration of the device with the domain to a domain data providing unit of the domain manager using the domain information;
- transmitting a device key of the device to the domain manager, wherein the device key is comprised in device information of the device;
- and
- receiving a domain key of the domain from the domain data providing unit of the domain manager,
