Consumer MPEG2 multimedia digital satellite receiver

Abstract

In spite of the delays in availability of digital video and other broadband DTH services, new and high capacity satellite networks are currently under deployment. This paper presents a digital set-top box developed for 54 MHz wide Ku band satellite delivery systems with coherent QPSK demodulation with a total bit rate of 90 Mbps and aggregate data rate of 54 Mbps which is able to provide 8 high quality video-audio programs per satellite transponder with additional data services like EPG (Electronic Program Guide), low speed (up to 38.4 Kbps) asynchronous data and MPEG2 PSI (Program Specific Information) and DVB SI (Digital Video Broadcasting System Information) data tables.
