Abstract: A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided. The metadata may include a minBufferTime attribute indicating a minimum amount of initially buffered media content. A terminal may receive content from a server before playback of the content, and may buffer the content by at least the minimum amount. The metadata may include a range attribute that designates a range of a target indicated by a Uniform Resource Locator (URL). The terminal may receive bytes designated by the range attribute from the URL, and may play back the content using the received bytes.

Abstract: A method of acquiring an Internet protocol (IP) address to control a standby mode of a set-top box, and the set-top box and a power management server performing the method are disclosed. The method may include determining whether a state of the set-top box changes from a broadcasting state in which a broadcasting service is provided to a passive standby state in which a network connection between the set-top box and a headend providing the broadcasting service is blocked, receiving state information associated with an IP address allocated to the set-top box for the network connection in response to the state of the set-top box changing to the passive standby state, and transmitting, to the set-top box, a state change command to maintain the network connection for the IP address allocated to the set-top box based on the received state information.

Abstract: Provided is a node control apparatus communicating an external Internet Protocol (IP) network and managing a plurality of mobile nodes included in a local network. The node control apparatus manages information relating to the plurality of mobile nodes, each equipped with one or more wireless interfaces, configures one or more groups by classifying the plurality of mobile nodes according to the type(s) of the wireless interface(s) of each of the plurality of mobile nodes, selects a representative node for each of the groups, and allows the member nodes of each of the groups to communicate with the external IP network via their representative node. Therefore, it is possible to minimize power consumption by selectively using a wireless interface for use in connecting to the representative node of each of the groups.
Abstract translation: 提供了一种通信外部因特网协议（IP）网络并管理包括在本地网络中的多个移动节点的节点控制装置。 节点控制装置管理与配置有一个或多个无线接口的多个移动节点有关的信息，通过根据无线接口的类型对多个移动节点进行分类来配置一个或多个组 多个移动节点中的每一个为每个组选择代表性节点，并且允许每个组的成员节点经由其代表节点与外部IP网络通信。 因此，可以通过选择性地使用无线接口来连接到每个组的代表性节点来最小化功耗。
