Abstract: A method for protecting personal information in a home network is provided, in which a controlled device receives a subscribe request for a service of the controlled device, from a control point, and accepts the subscribe request. The controlled device receives information about the control point from the control point, and performs event delivery to the control point according to a policy that is set based on the information about the control point, when an event occurs in the controlled device.

Abstract: Disclosed is a method and apparatus for processing multiple inputs from a plurality of users in a home network. A control point requests electronic devices in the home network to transmit input capability information, receives the input capability information as a response to the request from the electronic devices, and performs session setup using the input capability information by determining a receiver for receiving input signals and at least two senders for sending input signals. The control point transmits input signals transmitted by the at least two senders to the receiver.

Abstract: A method of processing an action executes an action requested by a control point for controlling a controlled device through a network, stores a result of executing the action as a pending result of the action when a network connection between the controlled device and the control point is terminated, and transmits the stored pending result of the action to the control point when the network connection between the controlled device and the control point is resumed.
