FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61834-4 has been prepared by subcomittee 100B: Audio, video and
multimedia information storage systems, of IEC technical committee 100: Audio, video and
multimedia systems and equipment.
The text of this standard is based on the following documents:
FDIS Report on voting
100B/164/FDIS 100B/174/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.

IEC 61834 consists of the following parts:
– Part 1: General specifications;
– Part 2: SD format for 525-60 and 625-50 systems;
– Part 3: HD format for 1125-60 and 1250-50 systems;
– Part 4: Pack header table and contents;
– Part 5: Character information system.
This document is Part 4 of IEC 61834 and describes the pack header table and the contents of
packs which are applicable to the whole recording system of helical-scan digital video cassette.
Part 1 describes the common specifications for the helical-scan digital video cassette recording
system using 6,35 mm magnetic tape.
Part 2 describes the specifications for 525-60 and 625-50 systems which are not included in
Part 1.
Part 3 describes the specifications for 1125-60 and 1250-50 systems which are not included in
Part 1 and Part 2.
Part 5 describes the character information system which is applicable to the whole recording
system of helical-scan digital video cassette.
For manufacturing SD digital video cassette recording system, Part 1, Part 2, Part 4 and Part 5
are referred to.
For manufacturing HD digital video cassette recording system, Part 1, Part 2, Part 3, Part 4
and Part 5 are referred to.
This part of IEC 61834 is to be referred to particularly when the pack header table and the
contents are to be checked.
A bilingual version of this standard may be issued at a later date.
