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: 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.
Abstract translation: 提供了一种用于发送具有报头的基于分组的媒体数据的方法，其中开销最小化。 一种用于媒体数据传输的方法可以包括以下步骤：封装媒体数据以允许媒体片段单元（MFU）头部和M单元头部共享一种格式; 允许MMT有效载荷格式包括用于RTP报头不支持的操作的报头字段，并将封装的媒体数据从特定实体传送到另一个实体; 并控制媒体数据的传送。 因此，传输开销最小化，使得可以有效地传输媒体数据。
