Analysis of Digital Video Broadcast Second Generation Satellite (DVB-S2) for Simultaneous Voice Communication & TV Broadcast

Abstract

The growing rivalry mainly in search of the audience in today’s TV broadcasting industry has made the real-time gathering of latest national and international developments through contribution link, the most critical part. The communication among field staff/reporter and head office is through the cellular system. In areas with no mobile coverage, it is almost impossible to stay in touch and very difficult to share the latest updates. In this paper, a detailed study of Digital Video Broadcast- second generation Satellite (DVB-S2) standard used in DSNG (Digital Satellite News Gathering) link is carried out for the feasibility of two ways communication with the digital television broadcast. We have used communication system toolbox in MATLAB Simulink to implement our model. We created the system according to the DVB-S2 standard and also used RF Satellite channel instead of AWGN (Adaptive White Gaussian Noise) channel. Simulation results show that communication signal can be transmitted with digital video television broadcast in DVB-S2 baseband frame.
