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. According to the system and method, even when the function of a peer does not normally work on a P2P network, a donor as a replacement of the peer is utilized, thereby providing QoS-enabled digital content to a user requesting the digital content.

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.

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.
