NATIONAL FOREWORD

This Indian Standard (Part 8) (First Revision) which is identical with IEC 60728-10 : 2014 ‘Cable networks for television signals, sound signals and interactive services - Part 10: System performance for return paths’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on recommendation of the Audio, Video and Multimedia Systems and Equipment Sectional Committee and approval of the Electronics and Information Technology Division Council.

This standard was originally published in 2002 and was based on IEC 60728-10 : 2001. The first revision of this standard has been undertaken to align it with the latest version of IEC 60728-10 : 2014.

This Indian Standard is published in several parts. The other parts in this series are:

Part 1 Safety requirements

Part 3 Active coaxial wideband distribution components

Part 4 Passive coaxial wideband distribution components

Part 5 Headend

Part 7 Electromagnetic compatibility of systems

Part 9 Interfaces of cabled distribution systems for digitally modulated signals

Part 10 Optical equipment

The text of IEC Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker, while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
