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.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

modulation method and basic system data for video compressed data.
Part 2 describes the specifications for encoding process and data format for 525i and 625i
systems.
The committee has decided that the contents of this publication will remain unchanged until the
maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed;
• withdrawn;

Part 3: Data stream format
1 Scope
This part of IEC 62071 defines the format of the data stream for the synchronous exchange of
DV-based audio, data, and compressed video (whose data structure is defined in SMPTE 314M)
over the interface defined in SMPTE 305M. It covers the transmission of audio, subcode data
and compressed video packets associated with DV-based 25 and 50 Mb/s data structures
including faster-than-real-time transmission for 525/60 SDTI and 625/50 SDTI systems.
This standard does not include the data stream of a DV-compressed structure as defined in
SMPTE 322M.
Space within SMPTE 305M not used by a data stream conforming to this standard may be used
for the transmission of data other than those representing DV-based audio, data and
compressed video.
In this standard, the 60 Hz system refers to the field frequency 59,94 Hz system and the 50 Hz
system refers to the field frequency 50,0 Hz system.

4.1 SDTI header packet data
The header packet data words of the serial data transport interface (SDTI) associated with this
data stream format shall conform to SMPTE 305M. When the SDTI interface is transporting a
data stream conforming to this standard, the block type word within the SDTI header packet
shall have the value 173 for transported data contained in fixed-size blocks when ECC (error
h
correction code) is used and the value
233 when ECC is not used.
h
4.2 Payload
The payload is composed of consecutive fixed-size blocks (see Figure 1). The SDTI data type
word shall identify the data type of this payload with the value 221 .

5 Stream block format
The stream block format is shown in Figure 1. The length of each stream block is 170 words,
including a secondary header, two DIF (digital interface) block IDs, two DIF block data (of
stream data) and an ECC block. The secondary header contains reserved data words, signal
type words, and a transmission type word. The complete word structure of the stream block for
a compressed video data stream is defined below:
Reserved data : 3 words
Signal type : 2 words
Transmission type : 1 word
