(Main)Cable networks for television signals, sound signals and interactive services - Part 1: System performance of forward paths
Cable networks for television signals, sound signals and interactive services - Part 1: System performance of forward paths
IEC 60728-1:2014 is applicable to any cable network (including individual receiving systems) having in the forward path a coaxial cable output and primarily intended for television and sound signals operating between about 30 MHz and 3 000 MHz. It specifies the basic methods of measurement of the operational characteristics of cable network having coaxial cable outputs in order to assess the performance of these systems and their performance limits. This fifth edition cancels and replaces the fourth edition published in 2007 and constitutes a technical revision. It includes the following changes: - redrafting of measurement procedure and updating of performance requirements to include DVB-T2 signals; - reference to IEC 60728-1-1 for home networks; - reference to IEC 60728-1-2 for performance requirements at system outlet in operation.

Kabelska omrežja za televizijske in zvokovne signale ter interaktivne storitve - 1. del: Lastnosti sistema za naprejšnje poti (IEC 60728-1:2014)
Standard se uporablja za katero koli kabelsko omrežje (vključno s posamičnimi sistemi za sprejem), ki ima v naprejšnji poti koaksialni kabelski izhod ter je namenjeno za televizijske in zvokovne signale s frekvenco med približno 30 MHz in 3000 MHz. Ta del standarda IEC 60728 določa osnovne metode merjenja obratovalnih značilnosti kabelskega omrežja s koaksialnimi kabelskimi izhodi, da bi se ocenile lastnosti teh sistemov ter omejitve njihovega delovanja.
