IEC 60728-1-2:2014 provides the minimum performance requirements to be fulfilled in operation at the system outlet or terminal input and describes the summation criteria for the impairments present in the received signals and those produced by the CATV/MATV/SMATV cable network, including individual receiving systems. It is applicable to cable networks intended for television signals, sound signals and interactive services operating between about 5 MHz and 3 000 MHz. The frequency range is extended to 6 000 MHz for home distribution techniques that replace wired cords with a wireless two way communication inside a room (or a small number of adjacent rooms) that uses the 5 GHz to 6 GHz frequency band. This second edition cancels and replaces the first edition published in 2009, and constitutes a technical revision. It includes the following technical: update of performance requirements in Clause 7 to include those for DVB-T2 signals.

This publication is to be read in conjunction with IEC 60728-1:2007.
