As incorporated in RR-2008

This is not the text in force. It is the version of this Recommendation that RR-2008 gave treaty-binding force, kept so that the incorporated set can be read as it stood at each conference.

Version history

Version evolution

The number in each cell (e.g. −9) is the Recommendation's revision number — the “-9” in ITU-R M.585-9, not a negative value. So −8 → −9 means the binding reference moved from the 8th to the 9th revision.

Scope

protection ratios and associated protection masks are essential characteristics for the television signals in the broadcasting-satellite service (BSS) and associated feeder links;

Recommends

  1. that for any EPM/OEPM compatibility analysis carried out under Articles 4 and 5 of Appendices 30 and 30A, Annex 1 should be applied;
  2. that the associated interference calculation methods of EPM/OEPM provided in Annex 2, should be used for the compatibility analyses referred to in recommends 1.
  3. NOTE 1 – The calculation method to generate protection masks provided in Annex 3 for BSS networks employing all types of digital phase shift keyed emissions may be applied in compatibility analyses for bilateral coordination between administrations.
  4. NOTE 2 – Further studies are needed to develop masks for interference between other types of emission (i.e. for analogue into analogue, digital into analogue and analogue into digital interference). Until such time as these masks are available, the method described in Annex 1 should be used when calculating interference between emissions when the interference is digital.
