Satellite Earth Stations and Systems (SES); Television Receive-Only (TVRO) equipment used in the Broadcasting Satellite Service (BSS)

This European Telecommunication Standard (ETS) gives minimum specifications for the standardisation of the technical characteristics of satellite receiving only earth stations, capable of receiving audio-visual signals and associated data. A specified quality of service is not a requirement of this ETS. The equipment considered in this ETS is confined to the "outdoor unit" that consists of the antenna with the feed network and the low-noise amplifier with its associated down-converter, referred to as Low-Noise Block (LNB) converter. The output interface towards the indoor unit is defined at the LNB output connector. Consequently the coaxial cable link to the "indoor unit", the intermediate frequency amplifier and the demodulator are not included in this ETS. For the "indoor unit" the relevant standard is prEN 50083: "Cabled distribution systems for television and sound signals". This ETS is applicable to Television Receive Only (TVROs) earth stations which receive audio-visual signals in the Broadcasting Satellite Service (BSS) Ku band frequency ranges from 11,70 GHz to 12,50 GHz.
The TVROs are classified into two different types according to the corresponding services:
   Type A for collective reception, in particular:
      - Community Antenna Television (CATV);
      - Master Antenna Television (MATV).
   Type B for individual reception, i.e. Direct To Home (DTH) equipment.
A clear distinction is made, wherever applicable between specifications for Type A and for Type B equipment in the various Clauses of this ETS. The received television signals can be PAL, SECAM, or the different MAC systems, all with the associated TV sound, and possibly other audio programmes.
Any other new TV systems (e.g. digital) may be received in the future, provided that those systems operate in the BSS Ku Band.
They could be:
- digital TV systems;
- MAC - packet family full channel digital mode.
Data may be present as coded signals inside television signals. Encrypted signals may also be accommodated.
NOTE: This ETS takes as main references for radio frequency specifications the WARC '77 plan (see [1], Appendix 30), and the CCIR relevant Recommendations (see Annex G, informative), but different assumptions are made taking into account the general trend towards very small aperture terminals. Following the decision made during WARC '92 to revise the WARC '77 plan, further developments of Radio Frequency (RF) parameters are expected in the near future and will require further studies.
This ETS specifies:
a) Requirements (indicated in Clause 5).
The requirements cover mechanical, electrical safety and the interface with the indoor unit as well as some electromagnetic compatibility aspects.
The test and measurement procedures associated with the normative requirements detailed in Clause 5 of this ETS shall be met in order to qualify compliance with this ETS.
b) Recommendations (indicated in Clause 6).
The recommendations are related to the quality of reception and are intended to assist manufacturers harmonise equipment design and to enable equipment distributors and end-users to better determine equipment performance. The test and measurement procedures associated with the informative recommendations detailed in Clause 6 of this ETS are given for verification purposes only. The compliance with the recommendations will not be taken as a condition to comply with the standard for TVRO equipment.
All the tests related to the requirements shall be performed and the results entered in the data sheet of the test report. The ability to comply with the recommendations shall also be noted in the data sheet of the test report.
