Overview
This part of IEC 60728 defines the characteristic values of equipment used in headends of terrestrial broadcast and satellite reception systems (excluding outdoor units for satellite reception and broadband amplifiers in the headend described in IEC 60728-3). The standard differs from the previously valid standard (2008 edition) as follows: the title and scope have been adapted. Several new terms have been added to Clause 3. The following clauses have been amended: 4.1 Measurement method for digitally modulated signals; 4.6.2 RF signal-to-noise ratio for digitally modulated signals; 4.8.2 Measurement method for group delay distortion at DVB channel converters; 4.9 Phase noise of RF carriers; 4.15 Decoding reserver (teletext); Annex D Special national conditions; Annex E Correction factors for noise interference; Annex F Digital signal levels and bandwidths; Annex G Minimum frequency spacing of converted satellite signals in the intermediate frequency range; Annex H Measurement errors due to mismatched equipment; Annex I Correction factor for a spectrum analyzer. The responsible committee is DKE/K 735 "Kabelnetze und Antennen für Fernsehsignale, Tonsignale und interactive Dienste" ("Cable networks for television signals, sound signals and interactive services") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
