HIGH DEFINITION (HD) RECORDING LINK GUIDELINES

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.

International Standard IEC 62546 has been prepared by technical area 9: Audio, video and
multimedia applications for end-user network, of IEC technical committee 100: Audio, video
and multimedia systems and equipment.
The text of this standard is based on the following documents:
CDV Report on voting
100/1470/CDV 100/1558/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.

INTRODUCTION
With the global introduction of High definition (HD) TV services, receivers, and consumer
recording equipment, the need has arisen for a universal recording interface to connect
receivers and recorders.
This International Standard presents a comprehensive proposal for this interface including
content protection 62H [2 ]63H [3 ] 0F . The proposal – intended as a guideline – leverages existing
standards IEC 62481-1, and 64H [4] in the field, ensuring interoperability between receivers and
recorders.

device and monitor provided by HDMI Licensing, LLC.
Figure 1 – High definition reception and recording

The starting point for the proposal is an in-home configuration depicted in 65HFigure 1. The
assumption is that both the receiver (e.g. STB) as well as the recorder (e.g. BD-recorder) are
connected to the display via an HDMI interface 66H [4]. The proposed recording interface
connects the recorder to the receiver and carries compressed signals only. Obviously, the
receiver functionality can be integrated into the display.
The proposed interface recognises the fact that a large amount of content will be made
available in the form of a Pay-TV and thus be protected via a Conditional Access (CA) system.
The required CA functionality is assumed to be contained in the receiver.
