IEC 60728-5:2015 specifies the characteristics of equipment used in the headends of terrestrial broadcast and satellite receiving systems (without satellite outdoor units and without those broadband amplifiers in the headend as described in IEC 60728-3). It:- covers the frequency range 5 MHz to 3 000 MHz;- identifies performance requirements for certain parameters;- lays down data publication requirements for certain parameters;- stipulates methods of measurements;- introduces minimum requirements defining quality grades (Q-grades). This third edition cancels and replaces the second edition published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:- new text for the introduction, following the scope of IEC TC 100/TA 5;- introduction of IPTV to the scope;- headend specification for digital terrestrial TV signals according to the DVB-T2 standard;- headend specification for digital TV signals in cable networks according to the DVB-S2 standard.
