20.500.12556/RUL-29598 Napredne satelitske komunikacijske tehnike za video prenos Advanced satellite communication techniques for video transmission Hiter razvoj televizijske industrije je eden ključnih razlogov za razvoj tehnologije pri prenosu satelitske slike in tona. Prvi sistem satelitske digitalne video radiodifuzije je razvila delovna skupina DVB Project leta 1993. Imenuje se DVB-S. Zaradi napredka slike standardne kakovosti v visoko ločljivost, je DVB-S po skoraj desetih letih delovanja potreboval nadgradnjo sistema. Potreba po večjem prenosu podatkov, kakovosti in robustnosti je leta 2005 narekovala izdelavo satelitske digitalne radiodifuzije druge stopnje, ki je uporabnikom omogočala nove naprednejše modulacijske tehnike. Tako kot DVB-S se je tudi DVB-S2 obdržal slabih 10 let, vse do prihoda tretje generacije prenosa signala, imenovanega NS3, ki ga je osnovalo podjetje NovelSat. Prednosti NS3 so naprednejše modulacijske tehnike, izboljšana poraba pasovne širine, boljša spektralna učinkovitost in kompatibilnost z dosedanjima DVB-S in DVB-S2 sistemoma. The rapid development of the television industry is one of the main reasons for development of the satellite video transmission technology. The first such system was the Digital Video Broadcasting – Satellite known as DVB-S. It was developed in 1993 by working group named DVB Project. DVB-S soon needed the upgrade, because of high definition videos which required higher data rate. The upgrade followed in DVB-S2 which stands for Digital Video Broadcasting – Satellite – Second Generation which provided users with advanced modulation techniques and was also compatible with previous DVB-S system. DVB-S2 was around for almost 10 years until the third generation system arrived. The third generation system NS3 was developed by NovelSat. The advantages are advanced modulation techniques, a better use of spectral efficiency and compatibility with DVB-S and DVB-S2 systems.
