摘要： 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.

摘要： 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.

摘要： 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.
摘要翻译：提供了一种在基于对等（P2P）的网络中发送和接收个人广播数据的方法。接收个人广播的终端（客户端）通过使用个人广播频道的电子节目指南（EPG）信息或统一资源定位符（URL）来请求跟踪服务器进行观看预约，发送个人广播的终端（广播者）数据接收到从跟踪服务器进行个人广播的观看预约的客户端列表，并且在开始个人广播的时候通知客户关于个人广播的开始。因此，客户端在进行观看预约之后通过连接到个人广播频道通知个人广播的开始被通知，而不必等待个人广播开始。
