RETRASDIG-TVD

In this project the GTAS group developed a unit called DAT (Digital to Analog Transmodulator), which receives the satellite digital TV signal (QPSK modulated) and transforms this signal into a conventional analog PAL channel. The DAT carries out the following tasks: QPSK demodulation, FEC channel decoding (Reed-Solomon and Viterbi), demultiplexing of the MPEG-2 stream and audio /video decoding en enconding form MPEG to PAL. We used chips from LSI LOGIC and made the design, implementation and evaluation of the overall system.
