Abstract:
PURPOSE: A network ID based federation and single sign on authentication method is provided to perform SSO authentication between an NACF and a web application service using an IdP(Identity Provider). CONSTITUTION: NACF(Network Attachment Control Function) wire/wireless access federation authentication by an access network service provider(12) is received. Federation SSO authentication between an access network and a service network provider(13) is provided using the NACF authentication information if the authentication is performed. Or, federation SSO authentication between the access network and a web application service provider(14) is provided.
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:
PURPOSE: An advertisement-connected coupon providing system and a method thereof are provided to store coupon or advertisement data which a third business operator provides in a server which the business operator manages. CONSTITUTION: A coupon providing unit(16) provides corresponding coupon information through a service delivery platform(14) according to a coupon request from a user terminal(10). If there is an advertisement related to the provided coupon information, the coupon providing unit requests the advertisement to advertisement providing unit(18) through the service delivery platform. The coupon providing unit receives corresponding advertisement information from the advertisement providing unit. The coupon providing unit provides the advertisement information and the coupon information to the user terminal.
Abstract:
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.
Abstract:
The present invention provides methods for providing a media content performed by a client and by a server, a client for providing a media content, and a server for providing a media content. The method comprises: transmitting a request for the media content to a server based on a Media Presentation Description (MPD) of the media content; and receiving a segment of the media content based on the MPD, from the server. The MPD includes one or more periods, the period includes one or more adaptation sets, the adaptation set includes one or more representations, the representation includes one or more segments, the period is defined based on a period element including a start attribute and a duration attribute, and each of the representations starts from a start time of the period and continues to an ending point of the period. The start time of the period is determined one of below methods: i) when a start attribute exists in a first period element of the first period, a start time of the first period is equal to the start attribute, ii) when a start attribute does not exist in the first period element of the first period, and when a second period element of the second period includes a duration attribute, the start time of the first period is determined by adding the duration attribute of the second period element to a start time of the second period, and iii) when a start attribute does not exist in the first period element of the first period, and when the first period is the first of the one or more periods, the start time of the first period is set to 0. The second period is previous period with respect to the first period.
