BS EN IEC 60728-101-2:2023 PDF

1   Scope

This part of IEC 60728‑101 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.

NOTE 1 When a change of signal format is made at the headend , the summation of the impairments does not apply (see also Clause 6).

In a building divided into apartment blocks, the signals received by the antennas are distributed by the MATV / SMATV cable network up to the home network interface ( HNI ); the television signals are then distributed (inside the home) by home networks ( HN ) of various types up to the system outlet or terminal input. The cable network can support two-way operation, from the system outlet (or terminal input) towards the headend . The home network can use coaxial cables, balanced pair cables, fibre optic cables (glass or plastic) and also wireless links inside a room (or a small number of adjacent rooms) to replace wired cords.
