Abstract: A method for transmitting an MMT packet in an MMT (MPEG Media Transport) system includes: generating an MMT asset by performing encapsulation based on a Media Processing Unit (MPU) generated based on a media Access Unit (AU); generating MMT Composition Information on the MMT asset; generating an MMT packet by packetizing the MMT asset and the MMT-CI; and transmitting the generated MMT packet to a receiving side, wherein the MMT-CI may contain dependency information of the MMT asset on at least one other MMT asset. Accordingly, it is possible to indicate whether an MMT packet depends on other MMT assets when transmitting and receiving multi-layered media data, and to support proper decoding of the MMT asset when providing hybrid delivery-based MMT service.

Abstract: Disclosed is an apparatus and method of segmenting an object. An object segmentation method according to the present disclosure includes: receiving an input image; receiving a user input indicating at least one piece of information on a foreground region and a background region included in the input image; generating at least one among a foreground pixel list and a background pixel list using the received user input; calculating Gaussian distribution of at least one pixel that makes up the input image using at least one among the generated foreground pixel list and background pixel list; and determining whether the at least one pixel is a foreground pixel or a background pixel using the calculated Gaussian distribution.

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.
