21、cifies the mapping of type D-11 compressed picture data stream into the SDTI payload area (SMPTE 305.2M) together with the mapping of four channels of AES3 data and time-code data into H-ANC packets. Type D-11 compressed picture data-stream mapping is defined for source-coded picture rates of 24/1,0
22、01/P,24/P, 25/P, 50-I, 30/1,001/P and 60/1,001. For the transmission of compressed picture data coded at source picture rates of 25/P and 50/I, the SDTI interface operates at a frame rate of 25 Hz. For the transmission of compressed picture data coded at source picture rates of 30/1,001P and 60/1,00
23、1I, the SDTI interface operates at a frame rate of 30/1,001 Hz. The transmission of compressed picture data coded at the source picture rates of 24/1, 001/P and 24/P require the SDTI interface to operate at frame rates of 24/1, 001Hz and 24 Hz with the parameters defined in Annexes A and B of this s

28、a stream packets over SMPTE 305.2M (SDTI). Type D-11 data stream comprises packets of basic blocks containing compressed picture data and auxiliary picture data as specified in IEC 62356-2. Four channels of 24-bit AES3 data are optionally mapped into the H-ANC space of the interface according to SMP
29、TE 272M. In addition, VITC may also be mapped into the H-ANC space. Type D-11 data-stream packets are grouped into six equal data segments of which the first three data segments are mapped onto the first field of the SDTI and the last three data segments are mapped onto the second field of the SDTI,
30、 as shown in Figure 1 and Table 1. Figure 1 also includes the optional four channels of 24-bit AES3 data mapped into the H-ANC space. VITC data may also be mapped into the H-ANC space.
