摘要： In the conventional content, a minimum access unit of the random access information is one frame unit. In the case of SVC video content, one frame consists of a plurality of scalable layers. The SVC data can be used for each salable layer only when the data is accessible for each scalable layer. The present invention provides a method and apparatus for transmitting and receiving an SVC file for each scalable layer wherein the SVC file can be accessed for each scalable layer by allowing metadata to contain a layer descriptor in a network abstraction layer unit (NALU) or in a byte unit.

摘要： Provided is a method for transmitting packet-based media data having a header in which an overhead is minimized. A method for media data transmission may comprise the steps of: encapsulating media data to allow a media fragment unit (MFU) header and an M-unit header to share one format; allowing an MMT payload format to include a header field for an operation which is not supported by an RTP header, and transferring the encapsulated media data from a specific entity to another entity; and controlling the transfer of the media data. Therefore, a transmission overhead is minimized, so that it is possible to efficiently transmit media data.

摘要： Disclosed is a method for generating a substream ID usable in transmitting media content based on a plurality of scenarios, and allocating the substream ID for transmitting media. A method for allocating an ID for transmitting media content comprises: a step of generating a substream ID containing information required for transmitting the media content based on a certain scenario from among a plurality of scenarios; and a step of transmitting the substream ID to a client. According to the present invention, a header for the transmission of media may be simplified, media content may be transmitted regardless of the number of ports, number of servers, and presence/absence of additional information, an application to be introduced in the future may be used, and backward compatibility for an existing media content transmission system may be provided.

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 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.
