ETSI - PRETS 300 158
Satellite Earth Stations (SES); Television Receive-Only (TVRO) Satellite Earth Stations (DE/SES-4001)
|Publication Date:||1 January 1991|
The scope of this is to give minimum specifications for the standardization of the technical characteristics of satellite receiving earth stations, capable of receiving television signals.
The equipment considered in this ETS, is confined to the "outdoor unit" that consists of the antenna with the feed and the low-noise amplifier with its associated down-converter, referred to as Low-Noise Block converter (LNB).
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 covered in this ETS.
Standards for the "indoor unit" are the responsibility of CENELEC. This ETS is applicable to earth stations which receive programmes in the Fixed Satellite Services (FSS) frequency ranges, from 10,70 GHz to 11,70 GHz and from 12,50 GHz to 12,75 GHz (Ku band).
The TVROs are considered for the following services:
- cable distribution head ends:
- community reception systems:
- individual reception systems.
The received television signals can be PAL, SECAM, NTSC 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 those systems operate with the FSS ku band.
Data may be present as coded signals inside television signals.
