Sparklies
From Biocrawler, the free encyclopedia.
Sparklies are an official term, as used by Sky Television and a number of hardware makers including Amstrad and Pace, for interference on analogue satellite television transmissions.
Sparklies are black or white 'hard' interference dots (as opposed to the 'soft' interference patterns of terrestrial television), caused by either too weak or too strong a signal. When within the satellites rated reception footprint, sparklies are most likely to be caused by a misaligned dish, or LNBs which are too high- or too low-gain for the dish and receiver.
Sparklies do not occur on digital satellite systems, with MPEG artificating being the nearest equivalent symptom.
