IEC 62356-3:2003

Video recording - 12,65 mm type D-11 format - Part 3: Data mapping over SDTI

IEC 62356-3:2003 specifies 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 24/1,001/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 60/1,001I, the SDTI interface operates at a frame rate of 30/1,001 Hz.

Enregistrement vidéo - Format de type D-11 12,65 mm - Partie 3: Mappage de données à travers l'interface de transport de données série (SDTI)

La CEI 62356-3:2003 spécifie le mappage du flux de données d'images compressées de type D-11 dans la zone de charge utile SDTI (Interface de transport de données série) (SMPTE 305.2M) ainsi que le mappage de quatre canaux de données AES3 et des données de code temporel dans des paquets H-ANC. Le mappage du flux de données d'images compressées de type D-11 est défini pour les vitesses d'images codées à la source de 24/1,001/P, 24/P, 25/P, 50-I, 30/1,001/P et 60/1,001. Pour la transmission de données d'images compressées codées à des vitesses d'image source de 25/P et 50/I, l'interface de transport de données série fonctionne à une vitesse de trame de 25 Hz. Pour la transmission de données d'images compressées codées à des vitesses d'images source de 30/1,001P et 60/1,001I, l'interface de transport de données série fonctionne à une vitesse de trame de 30/1,001 Hz.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.

This International Standard specifies 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

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 60/1,001I, 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 standard.

1 Scope
This International Standard specifies 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 24/1,001/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 60/1,001I, 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 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 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 SMPTE 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, 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.
