Helical-scan digital video cassette recording system using 12,65 mm (0,5 in) magnetic tape - Format HD-D5 -- Part 1: VTR specifications

This part of EN 62330 specifies the content, format, and recording method of the data blocks containing HD compressed video data defined in part 2, audio, and associated data which form the helical records on 12,65 mm (0,5 in) tape in cassettes as specified in EN 61835. In addition, this standard specifies the content, format, and recording method of the longitudinal record containing tracking information for the scanning head associated with the helical records, and also the longitudinal cue audio, and time and control code. One video channel of HD compressed video data and four independent audio channels are recorded in the digital format. Each of these channels is designed to be capable of independent editing. The HD compressed video data are derived from the following HD video signal: 1080 line / 59,94 Hz field frequency interlace system 720 line / 59,94 Hz frame frequency progressive system

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 specifications, 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 62330-1 has been prepared by Technical Area 6: Higher data rate
storage media and equipment of IEC technical committee 100: Audio, video and multimedia
systems and equipment.
It was submitted to the national committees for voting under the Fast Track Procedure as the
following documents:
CDV Report on voting
100/504/CDV 100/603/RVC
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this publication will remain unchanged until
2008. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

Part 1: VTR specifications
1 Scope
This part of IEC 62330 specifies the content, format, and recording method of the data blocks
containing HD compressed video data defined in part 2, audio, and associated data which
form the helical records on 12,65 mm (0,5 in) tape in cassettes as specified in IEC 61835.
In addition, this standard specifies the content, format, and recording method of the
longitudinal record containing tracking information for the scanning head associated with
the helical records, and also the longitudinal cue audio, and time and control code.
One video channel of HD compressed video data and four independent audio channels are
recorded in the digital format. Each of these channels is designed to be capable of
independent editing.
The HD compressed video data are derived from the following HD video signal:
• 1080 line / 59,94 Hz field frequency interlace system
• 720 line / 59,94 Hz frame frequency progressive system
Figure 1 and Figure 2 show block diagrams of the processes involved in the recorder.
