Abstract

Satelitske komunikacije omogućavaju prijenos signala između pošiljatelja i primatelja preko satelita. Najvažnija i najrasprostranjenija primjena satelitskih komunikacija je digitalna satelitska televizija. Izvorna norma za modulaciju i kodiranje digitalne satelitske televizije je DVB-S, a norma novije generacije je DVB-S2. Uvođenjem DVB-S2 norme omogućena je primjena Adaptivnog kodiranja i modulacije (eng. Adaptive coding and modulation, ACM) i primjenjuju se poboljšane tehnike kodiranja i moduliranja signala. Procjena parametara kvalitete DVB-S i DVB-S2 normi pokazala je da DVB-S2 norma pruža kvalitetniji prijenos digitalnog TV signala putem satelita, odnosno povećana je učinkovitost u prijenosu podataka i zadržana je optimalna zaštita podataka.

Abstract (english)

Satellite communications enable the transfer of signal between the sender and the receiver by the use of satellite. The most relevant and the most prevalent application of satellite communications is digital satellite television. The original norm to modulate and code digital television is DVB-S, and the norm of newer generation is DVB-S2. By introducing the DVB-S2 norm the implementation of Adaptive coding and modulation (ACM) is enabled, and improved signal coding and modulating are being used. Estimation of the quality parameters of DVB-S and DVB-S2 norms demonstrated that DVB-S2 norm delivers a better quality transfer of digital TV signal using satellite, apropos the efficiency in the transfer of data is increased and optimal protection of data is secured.
