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.

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: 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: The present invention discloses an apparatus and a method for transmitting a packet and an apparatus and a method for receiving a packet, based on a timing model of an MPEG media transport (MMT) system, which is integrated by considering the advantages of a timing model in an MPEG-2 system and an RTP timing model. The apparatus for transmitting the packet transmits the packet from the MMT system, and comprises: a video stream that is encoded based on an input picture; and an MMT packetizing portion for generating the MMT packet by packetizing an audio stream that corresponds to the video stream, wherein the MMT packetizing portion generates the MMT packet by including synchronization information, which is generated based on a system time clock (STC) that is a master program clock for a video and audio encoder, and an MMT buffering delay. As a result, synchronization of various media sources, measurement of a packet arrival jitter, as well as STC clock locking of the apparatus for transmitting and the apparatus for receiving the MMT can be achieved.
