1 scope
This International Standard specifies the mapping of type D-11 compressed picture datastream into the SDTl payload area (SMPTE 305.2M) together with the mapping of fourchannels of AES3 data and time-code data into H-ANC packets. Type D-11 compressedpicture data-stream mapping is defined for source-coded picture rates of 24/1,001/P,24/P,25/P，50-l，30/1,001/P and 60/1,001.For the transmission of compressed picture data codedat source picture rates of 25/P and 50/l, the SDTl interface operates at a frame rate of 25 Hz.For the transmission of compressed picture data coded at source picture rates of 30/1,001Pand 60/1,0011, the SDTl 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/Pand 24/P require the SDTl interface to operate at frame rates of 24/1,001Hz and 24 Hz withthe parameters defined in Annexes A and B of this standard.

3 General specifications
This standard specifies the mapping of type D-11 data stream packets over SMPTE 305.2M(SDTI). Type D-11 data stream comprises packets of basic blocks containing compressedpicture data and auxiliary picture data as specified in lEC 62356-2.
Four channels of 24-bit AES3 data are optionally mapped into the H-ANC space of theinterface according to SMPTE272M. In addition,VITC may also be mapped into the H-ANCspace.
Type D-11 data-stream packets are grouped into six equal data segments of which the firstthree data segments are mapped onto the first field of the SDTl and the last three datasegments are mapped onto the second field of the SDTl, 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-ANCspace.VITC data may also be mapped into the H-ANC space.
