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 are a method and apparatus for an adaptive HTTP streaming service using media content metadata. The media content consist of a series of periods. The metadata may include a start time attribute and/or a duration attribute for each period. The metadata may determine a start time of each period and a start time of each segment contained in each period. A terminal accesses the segments contained in each period, and performs decoding and rendering processes on the data of the media content contained in the segments, thereby reproducing the media content.

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： The present invention relates to an apparatus and method for transmitting and receiving a streaming service. The apparatus and method for transmitting and receiving a streaming service involve using a lightweight multimedia file suitable for HTTP streaming. An ISO file that is created by a non-interleaved storage method unsuitable for an HTTP streaming service can be converted, using an HTTP hint track, into a file of an interleaved storage method suitable for an HTTP streaming service. The ISO file may contain multimedia tracks for supporting multiple bit rates and resolutions. Chuck data of media tracks, which provide multiple multimedia qualities, can be efficiently acquired, and the acquired chuck data is stored in an interleaved method, thereby generating a lightweight ISO file suitable for an HTTP streaming service.
