Abstract

Contains guidelines for measurement in Digital Video Broadcasting (DVB) satellite, cable and terrestrial and related digital television systems. It also specifies a number of measurement techniques, such that the results obtained are comparable when the measurement is carried out in compliance with the appropriate definition.
