As shown in table 3, the MPEG-2 video is defined as " 0x02 ", and mpeg audio is defined as " 0x04 ", with identification stream type (stream_type).But, because if 3D three-dimensional video-frequency additional data only is defined as " 0x02 " as the 2D video, then there are two video flowings in the stream type (stream_type) of 3D three-dimensional video-frequency additional data in a program, therefore, in traditional 2D digital receiver, make a mistake.
Therefore, with respect in current standard, be defined as keeping or the value of user's special use in one come redetermination 3D three-dimensional video-frequency additional data flow.
Fig. 6 is the syntax graph according to the transport stream packet of one embodiment of the present of invention.
As shown in the figure, produce packetizing with the form of transmission stream (TS) grouping of regular length and flow PES substantially, and PES generally is divided into two parts: TS packet header and TS grouping pay(useful) load with 188 bytes.The TS packet header comprises sync byte and TS packet identifier (PID), and described PID is used to discern the TS grouping.TS grouping pay(useful) load comprises the basic stream (being PES_Ori and PES_3D) of the packetizing of video and is used for the PES (PES_Au) and the PSI of voice data.
The basic stream of packetizing (PES_Ori, PES_3D and PES_Au) is generated as the TS grouping based on the transmission flow structure of graphic MPEG-2 system standard (ISO/IEC 13818-1) in Fig. 6.Therefore, the packetizing that the packetizing that the packetizing that the transmission of Fig. 1 stream (TS) generation unit 160 receives original videos flows (PES_Ori), 3D three-dimensional video-frequency additional data substantially flows (PES_3D) and voice data substantially flows (RES_Au) substantially, and divides into groups by produce TS referring to the pid value that defines in Program Map Table.
