COMPACT DISC VIDEO SYSTEM - 12 cm CD-V
FOREWORD
1)
The formal decisions or agreements of the IEC on technical matters, prepared by Technical Committees on
which all the National Committees having a special interest therein are represented, express, as nearly as
possible, an international consensus of opinion on the subjects dealt with.
2)
They have the form of recommendations for international use and they are accepted by the National
Committees in that sense.
3)
In order to promote international unification, the IEC expresses the wish that all National Committees
should adopt the text of the IEC recommendation for their national rules in so far as national conditions will
permit. Any divergence between the IEC recommendation and the corresponding national rules should, as
far as possible, be clearly indicated in the latter.
This International Standard has been prepared by Sub-Committee 60A: Sound recording,
of IEC Technical Committee No. 60: Recording.
This standard should be read in conjunction with IEC 908: 1987.
The text of this International Standard is based on the following documents:
DIS Report on Voting
60A(CO)142
60A(CO)145
Full information on the voting for the approval of this standard can be found in the Voting
Repo rt
indicated in the above table.

INTRODUCTION
This International Standard specifies the implementation of video information as an
optional addition to IEC 908. Reference is made to IEC 856 and IEC 857.

COMPACT DISC VIDEO SYSTEM - 12 cm CD-V
1 Scope
This International Standard is applicable to a pre-recorded optical reflective disc system
called "compact disc video (CD video)" containing digital audio and "Laser vision" video
information.
In the case of CD video the subclauses mentioned in this standard shall modify the
relevant text in IEC 908.
2 Normative references
The following normative documents contain provisions which, through reference in this
text, constitute provisions of this International Standard. At the time of publication of this
standard, the editions indicated were valid. All normative documents are subject to
revision, and parties to agreements based on this International Standard are encouraged
to investigate the possibility of applying the most recent editions of the normative
documents indicated below. Members of IEC and ISO maintain registers of currently valid
International Standards.
