Design and implementation of DVB-S2 transport stream for onboard processing satellite

Digital Video Broadcasting (DVB-S2) is a digital television broadcast standard which is introduced as a successor for the DVB-S system. This standard is compatible with multiple input protocols (IP, MPEG-2, MPEG-4) which are either encapsulated in transport stream or generic stream. This encapsulation feature makes it possible to support voice, video as well as data known as the triple play. This protocol is also an open standard, which leads to interoperability among different service providers. This protocol is highly suitable for on-board processing satellite as different class of users can be serviced through a single system as well as low cost ground receiver are available. The design described here implements DVB-S2 frame structure for transport stream, single input with constant code rate of 1/2 and QPSK modulation, with a roll-off of 0.20. A Xilinx Virtex®-5 FPGA is used to implement this design as this FPGA is also available in radiation tolerant version.
