GUIDELINE FOR IMPLEMENTATION OF
COPY CONTROLLED MULTIMEDIA INTERFACE

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.
The main task of IEC technical committees is to prepare International Standards. In
exceptional circumstances, a technical committee may propose the publication of a technical
specification when
• the required support cannot be obtained for the publication of an International Standard,
despite repeated efforts, or
• the subject is still under technical development or where, for any other reason, there is the
future but no immediate possibility of an agreement on an International Standard.
Technical specifications are subject to review within three years of publication to decide
whether they can be transformed into International Standards.
IEC 62436, which is a technical specification, has been prepared by technical area 4: Digital
system interfaces and protocols, of IEC technical committee 100: Audio, video and multimedia
systems and equipment.

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
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
• transformed into an International standard,

INTRODUCTION
Various IEC standards have included methods for transmission of copy control information at
the time when they were developed. For instance, IEC 61119-6 defines copyright status bit for
DAT recorder, and IEC 60958-3 defines the L bit that is specified in IEC 61119-6.
The current consumer products become more complex and use the many IEC standards in
one product.
For instance, a DVD player produces its high quality audio signal securely through
IEC 61883-6, it also performs CD quality audio signal through IEC 60958 or IEC 61937, and
the DVD player can produce audio signals through the other interface using IEC 60958
conformant data format, defined in IEC 61883-6.
Another example is a digital video recorder with hard disk drive or DVD that produces audio
signal to the other audio recorder using IEC 60958 or IEC 61883-6.
These consumer products use many interface standards and should give copy control
information and other information appropriately.
This guideline describes
– the relation between digital interface standards,
– the relation of copy control information and related information,
– the method for information implementation.

4.2 Relation between IEC standards
Figure 1 shows the relation between digital audio interface standards IEC 60958, IEC 61937
and IEC 61883-6.
IEC 60958-1 is the fundamental standard of these related standards, and it defines the basic
structure. The application standards derived form IEC 60958-1 for the linear PCM audio data
transmission are IEC 60958-3 for consumer use and IEC 60958-4 for professional use.
IEC 61937 is derived from IEC 60958, it specifies the data packet structure based on
IEC 60958-1, it is mainly for the transmission of compressed audio data. IEC 61937-1 and
IEC 61937-2 specify the general structure. In part 1 and part 2 of IEC 61937, transmission
method for the specific compressed audio format are specified from in part 3 to part 9 and
later parts. Also IEC 62105 specifies the receiver data transmission using IEC 61937-1
structure.
IEC 61883-6 specifies IEC 60958 conformant data format, this format defines IEC 60958-1
structure in IEC 61883-6. IEC 60958 conformant data format can transmit IEC 60958-1 and all
of its derivative standards.

5 Information for copy control
5.1 Audio
5.1.1 SCMS
IEC 61119-6 specifies SCMS. The status of SCMS is defined in 2 bits of DAT sub-code ID6.
• When ID6 is “00” Copyright status bit set for “not copyright protected”.
• When ID6 is “10” or “11” Copyright status bit set for “copyright protected”.
• The condition “01” in ID6 is not to be used.
A DAT recorder should provide the copyright status in the channel status of digital output. A
DAT recorder records digital audio signal form the digital input, the source device should
provide a category code with the copyright status bit “L-bit”, and it indicates the “generation
status” of the digital audio signal. A DAT recorder detects the copyright status and the
category, and controls recording permission and ID6 information referring the schemes
defined in IEC 61119-6.
The channel status includes the category code with the copyright status bit “L-bit”, which
transmits the generation status of SCMS.
IEC 60958-3 specifies the category codes in the channel status including the category codes
that IEC 61119-6 defines. In the channel status, bit 15 is referred to as the “L-bit”.
IEC 60958-3 Annex C describes the implementation for DAT in relation with input source
signal category.
IEC 60958-3 dose not mention about SCMS but defines category codes with L-bit.
5.1.2 Other information
IEC 61883-6 specifies the ancillary data for CCI in the DVD-Audio adoption layer, but the
compliance rule of CCI is not defined, it is defined by another specification, not an IEC
standard.
5.2 Video
IEC 61880-2 and IEC 62375 specify CGMS-A copy control information of analogue video
signal. In the identification data format, bit 7 and bit 8 of WORD 2 are assigned to CGMS-A. It
defies copyright status as follows.
Bit number 7, 8
0, 0 Copying is permitted without restriction
0, 1 Condition not be used
1, 0 One generation of copies may be made
1, 1 No copying is permitted
6 Implementation of copy control information of audio
6.1 IEC 61937 implementation
IEC 61937-1 defines that the interface format as defined in IEC 60958-1 and IEC 60958-3 is
used. The definition of channel status defined in IEC 60958-3 is applied to all parts of

 IEC 2016
IEC 61937, as the structure of IEC 61937 is described in 4.4. The category codes defined in
IEC 60958-3 is applied to the all parts of IEC 61937.
6.2 IEC 61883-6 implementation
IEC 61883-6 can transmit IEC 60958, IEC 61937 and others with IEC 60958 conformant data
format, the channel status is transmitted with IEC 60958 conformant data format as it is. The
category codes are transmitted with this structure.
7 Implementation of copy control information of audio accompanied with video
Audio signal accompanied with video is transmitted through IEC 60958-3, IEC 61883-6 and
other interfaces. CGMS-A is applied to video signal, the procedure of translation from CGMS-
A of video to SCMS of audio accompanied with that video depends on applications and
conditions (see Annex B).
8 Implementation of other information
Other information is defined in IEC 60958-3 by channel status and user data, for example
sampling frequency, SMPTE time code. This information is transmitted with IEC 61937 and
IEC 60958 conformant format.

Relation between IEC standards and other specifications

The Interface standards of IEC have a relation with the other specifications.
Figure A.1 shows IEC 60958 relation. AES 3 is a standard of AES for professional use,
CP-340 is a standard of the former JEITA (EIAJ) for consumer use. The former version of
IEC 60958 (1989) originates from AES 3 and CP-340 and is for consumer use. After that
IEC 60958 was revised and divided into three parts, as follows:
Part 1: General;
Part 3: Consumer applications and
Part 4: Professional applications; Part 4 reflects AES3.
CP-340 was revised to CPR-1201 and both were withdrawn, the latest one is CPR-1205,
which is an explanation of IEC 60958 and refers to IEC 60958-1 and IEC 60958-3.
AES 3(2002) version was converted into IEC 60958-4 (2003), the future version of AES 3 will
be transformed into the future edition of IEC 60958-4.

(informative)
Copy control information of audio accompanied with video

Video contents have its audio contents. Audio, video and multimedia equipment such as DVD-
Video player outputs video signal, audio signal and information. The copyright control scheme
of the video contents is CGMS-A or the other more complex schemes. This scheme will cover
the audio contents that are accompanied with the video contents.
The copyright control method and information that should be applied to the audio signal that is
output from the video equipment depends on the video format and its copy control schemes.
For instance, DVD-Video format employs its own copy control system that defines the
restriction to the digital audio interface.
Copyright control of digital audio interface is classified as follows.
• SCMS is applied.
• CGMS-A is applied.
• Other copy control scheme is applied.
• No output of audio signal.
IEC standards are applicable to SCMS and CGMS-A cases, another specification would be
applied to the other cases.

GUIDELINE FOR IMPLEMENTATION OF
COPY CONTROLLED MULTIMEDIA INTERFACE
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
