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.
摘要:
A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of media content are provided. The media content may include a sequence of one or more periods. The metadata may include a start time attribute and/or a duration attribute of each of the periods. The metadata may determine a start time of each of the periods, and a start time of each of segments included in each of the periods. A terminal may access segments included in each of the periods, may decode and render data of media content included in the segments, and may play back the media content.

A method includes transferring a general query message to managers of a mobility control server in response to receiving, from a router, the general query message for detecting a mobile node that requested to receive multicast data; storing, in a multicast mapping table, an address of the mobile node that requested to receive the multicast data when a membership report message of the mobile node is received from at least one of the managers and transferring the membership report message to the router; and forming a tunnel between the router and a manager that transfers the membership report message.

An Open Internet Protocol Television (IPTV) platform is provided. By providing remote medical services to users in the Open IPTV environment using a remote medical service providing apparatus including: an application programming interface (API) calling unit to call, when receiving a request for receiving a remote medical service from a counselor's terminal, an API of an Open Internet Protocol Television (IPTV) platform; and a service provider to provide the remote medical service to a user through the API, it is possible to provide remote medical service operators with environments where they can develop and share various remote medical to services and content.

An access point, a layer 2 switch, and multicast handover supporting method using the access point and the layer 2 switch are provided. According to the method of supporting multicast handover, when a mobile node is handed over from one cell to another while being provided with a multicast service in a wireless mobile communication network, the L2 switch performs multicast traffic routing in response to reception of MAC address information and multicast service source and group information from the access point. Hence, multicast traffic can be supported to be fast and seamlessly handed over within layer 2 network equipment.
摘要:
A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided. The metadata may include one or more BaseURL elements. Uniform Resource Locators (URLs) of segments forming media may be generated based on the BaseURL elements. Additionally, a URL of a segment may be generated by mapping a BaseURL element among the BaseURL elements to a sourceURL attribute of the segment. Segments indicated by generated URLs may be identical to each other.
