    Abstract: PURPOSE: An apparatus and a method for providing streaming contents are provided to generate an URL(uniform resource locator) of a segment by mapping any base URL elements from one or more base URL elements with a source URL attribute of the segment. CONSTITUTION: A server(110) can host DASH(dynamic adaptive streaming over HTTP) segments. A terminal(100) receives meta data(120) of a media from the server. The meta data includes the base URL element. The terminal processes the received meta data(130). The terminal extracts information provided through the meta data or the information included in the meta data. The terminal accesses the segment of the media based on the information provided through the meta data(140,150).

    Abstract: PURPOSE: An apparatus and a method for providing streaming contents are provided to generate an URL of a segment by mapping any base URL elements from one or more base URL elements with source URL attributes of the segment. CONSTITUTION: A terminal(100) receives meta data(120) for a media from a server(110). The server transmits meta data for the media to the terminal. The terminal processes received meta data(130). The terminal can extract information provided from the meta data or information included in the meta data. The terminal accesses a segment of the media based on the information provided from the meta data(140,150). The terminal reproduces the media by decoding and rendering data of the media included in the segment(160).

    Abstract: PURPOSE: A streaming content supplying apparatus and a method thereof are provided to analyze a URL of a segment by using a base URL element. CONSTITUTION: A terminal(100) receives metadata of media. The metadata includes one or more base URL(Uniform Resource Locator) elements. The terminal requests a segment of media by using the URL of the segment. The URL is analyzed about the base URL element. The terminal receives the segment. The terminal performs decoding and rendering of media data within the segment.

    Abstract: An apparatus and method for adapting a scalable video coding (SVC) bitstream is provided. The apparatus may include: a layer selection unit to select at least one quality layer from a plurality of quality layers contained in each of spatial layers of the SVC bitstream; a layer discarding unit to discard the at least one quality layer; and a layer dependency modification unit to modify a quality layer dependency between one or more quality layers remaining among the plurality of quality layers, or a spatial layer dependency between the plurality of spatial layers. Accordingly, it is possible to adapt the SVC bitstream where the entire quality of spatial layers is enhanced.

    Abstract: PURPOSE: A random access supporting method for a scalable video coding based streaming service is provided to support a scalable random access function by including an enhancement layer and a base layer in a DASH(Dynamic Adaptive Streaming over HTTP) service. CONSTITUTION: A segment index box includes an RAP(Random Access Point) index and an RAP(Random Access Point) offset. An RAP synchronization box provides synchronization information existed between SVC(Scalable Video Coding) video layer and an RAP by using the segment index box. A scalable random access function is provided by using the information of the RAP synchronization box and the segment index box.
