    • 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.
    • 本发明公开了一种基于MPEG媒体传输(MMT)系统的时序模型的用于传输分组的装置和方法,以及用于接收分组的装置和方法,其通过考虑时序模型 在MPEG-2系统和RTP时序模型中。 用于发送分组的设备从MMT系统发送分组,并且包括:基于输入画面编码的视频流; 以及MMT打包部分,用于通过打包对应于所述视频流的音频流来生成MMT分组,其中,所述MMT打包部分通过包括同步信息来生成所述MMT分组,所述同步信息基于系统时钟(STC) 视频和音频编码器的主节目时钟,以及MMT缓冲延迟。 结果,可以实现各种媒体源的同步,分组到达抖动的测量,以及用于发送的设备和用于接收MMT的设备的STC时钟锁定。
