Abstract: 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.

Abstract: A system and method of providing quality of service (QoS)-enabled digital content in peer-to-peer (P2P) networks are provided. The QoS-enabled service system on the P2P network includes: a service provider capable of providing digital content; one or more user nodes receiving digital content from the service provider; one or more donor nodes lending resources for providing digital content; and a supernode receiving information on user nodes and donor nodes, and a copy of digital content from the service provider, allowing the exchange of digital content among the user nodes through P2P networking, and when at least one user node experiences a P2P networking error during the exchange of the digital content, arranging for a predetermined number of donor nodes from among the one or more donor nodes to join the P2P networking.

Abstract: A method and an apparatus for transmitting additional information on digital broadcasting to an IPTV by using a home gateway are provided. The additional information on a digital broadcast program is received through an IP based home network, and a DVBSTP packet is created by using the received additional information, and the packet is transmitted to the home network. Accordingly, a user can immediately obtain various pieces of information on a current broadcast program or a next broadcast program, and thus scheduled recording can be accurately carried out by using information on a broadcast time of the broadcast program.

Abstract: Provided is a method of remotely controlling local network devices. The method includes periodically receiving an access request from each local network device in a local network, to which direct access from the outside is blocked, if a connection between a local network device and a server located outside the local network is formed as a result of receiving the access request, determining whether a command to be transmitted to the local network device exists, and if it is determined that a command to be transmitted to the local network device exists, transmitting the command to the local network device while the connect is being formed to control the local network device.

Abstract: A method and apparatus that provide additional information on a digital broadcast to home network devices in a home network, the method including receiving the additional information on a digital broadcast from an external network; determining at least one device among the home network devices as a receiving device of the additional information; and transmitting the additional information to the receiving device.

Abstract: A method and apparatus for managing a plurality of tuners for providing a broadcasting service to a plurality of devices in a home network. To provide the broadcast service requested by one of the devices, it is determined whether a tuner to which any broadcast service is pre-assigned can provide the requested broadcast service along with the pre-assigned broadcast service, and the requested broadcast service is additionally assigned to the tuner. If the tuner does not exist, a tuner to which no broadcast service is assigned is detected among from the tuners that can receive a broadcast program corresponding to the requested broadcast service, and the requested broadcast service is assigned to the tuner. Accordingly, in the environment in which various broadcast services are provided to a plurality of devices through a single gateway in a network, the broadcast services can be provided to the devices.
