Defines the characteristics of equipment used in the headends of terrestrial broadcast and satellite receiving systems. Only deals with the interfaces between headend components and only explains the function of the devices if this is necessary to support the description of the interfaces. Coverage includes: group delay variation, single channel intermodulation, luminance non linerarity, signal requirements, data publication requirements, and terms and definitions. Also gives diagrams and annexes.
