Abstract
The present disclosure provides a data transmission method of a system in an IP based broadcasting network, the data transmission method comprising the steps of: generating an MPEG media transport protocol (MMTP) packet using a media processing unit (MPU) for a service; generating an IP packet using the MMTP packet; generating a layer 2 (L2) packet using the IP packet and generating a layer 1 (L1) packet stream using the L2 packet; and transmitting the L1 packet stream, wherein absolute time information of the system is included in one of a transmission frame of the L1 packet stream and the L2 packet.
Claims2
A data transmission method of a system in an internet protocol (IP)-based broadcasting network, the method comprising:
- identifying information indicating a transmission time of a frame and a field related to timing information of the frame, wherein the field related to timing information of the frame includes information indicating a unit of a fractional second associated with the transmission time of the frame according to a value of the field;
- and
- transmitting the frame including the information indicating the transmission time of the frame and the field related to the timing information of the frame.
