FOREWORD
This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the Audio-
Video and Multimedia Systems and Equipment Sectional Committee had been approved by the Electronics
and Information Technology Division Council.
There is no ISO/IEC Standard on this subject.
The concerned Committee responsible for the formulation of this standard has reviewed the provisions of the
following International Standards and has decided that they are acceptable for use in conjunction with this
standard till Indian Standard on these are published:
