Abstract: A streaming service transmitting and receiving device and method are provided. An arrival interval jitter is an arrival delay time variation between TCP packets, which arrive at a device receiving a streaming service. The device receiving a streaming service determines a de-jitter buffering time to absorb a network jitter before TS packets in a TCP packet are inputted into a T-STD buffer model. An initial playback delay time of the device receiving a streaming service is determined by the de-jitter buffering time.

Abstract translation: 提供了一种流媒体服务发送和接收设备和方法。 到达间隔抖动是TCP分组之间的到达延迟时间变化，其到达接收流服务的设备。 接收流媒体业务的设备在TCP分组中的TS分组被输入到T-STD缓冲器模型之前，确定去抖动缓冲时间以吸收网络抖动。 接收流媒体服务的设备的初始回放延迟时间由去抖动缓冲时间确定。

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: 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.

Abstract: Disclosed are an apparatus and method for providing an adaptive HTTP streaming service using metadata for contents. The metadata includes minimum buffering time property indicating the minimum amount of media contents which are initially buffered. A terminal receives contents from a server before playing the contents and buffers the contents by at least the minimum amount. The metadata includes range properties indicating a target range to which a URL points. A terminal receives bytes from the URL which the range properties indicate, and plays the contents using the bytes.

Abstract: 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.

Abstract: The present invention relates to an apparatus and method for transmitting a packet and to an apparatus and method for receiving a packet in an MMT system. A packet transmission apparatus for transmitting a packet in an MPEG media transport (MMT) system may comprise an encapsulation unit which performs an encapsulation including the information relating to whether the time interval between composition time stamps (CTSs) of all of consecutive access units (Aus) in a media processing unit (MPU) is constant so as to encapsulate the media processing unit. Thus, the amount of timing information which may be contained within one media processing unit is reduced to increase the space practically used in data transmission, thereby improving the transmission efficiency.
