A broadcast receiver includes a mode determination unit to determine a current operation mode among a plurality of operation modes, a communication interface to transmit the determined current operation mode to a mobile device through interactive communication, and to receive a control command from the mobile device, and a controller to provide a service of the determined current operation mode according to the control command received from the mobile device. Accordingly, a user controls the broadcast receiver through the mobile device according to the operation mode so that user's convenience is improved.

Broadcast receiver, mobile device, service providing method, and broadcast receiver controlling method

Provided is a method of transmitting and receiving personal broadcasting data in a peer-to-peer (P2P) based network. A terminal (client) that receives a personal broadcast requests a tracker server for a viewing reservation by using electronic program guide (EPG) information or a uniform resource locator (URL) of a personal broadcasting channel, a terminal (broadcaster) that transmits personal broadcasting data receives a list of clients that made a viewing reservation of the personal broadcast from the tracker server and notifies the clients about starting of the personal broadcast when it is time to start the personal broadcast. Accordingly, the client starts streaming when notified of the starting of the personal broadcast by connecting to the personal broadcasting channel after making the viewing reservation, without having to wait for the personal broadcast to start.

Method and apparatus for transmitting and receiving personal broadcasting data based on peer-to-peer communication

Provided is a method of controlling a security level of a device. The method includes: requesting a server to authenticate a device, wherein the requesting is performed by a second application installed in the device; generating a device-server session for communication between the server and the device, based on the authentication of the device by the server; requesting access to the server by using the generated device-server session, wherein the requesting is performed by a first application installed in the device; and receiving content from the server due to the first application accessing the server.

Method and apparatus for handling security level of device on network

Method and apparatus for receiving data by using a plurality of pieces of information managed by a server that manages information about data that can be received via one or more peer-to-peer (P2P) networks and information about peers respectively connected to each P2P network.
