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.

摘要： 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.

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： 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.
摘要翻译：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。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。
