Screen Service Italia showcases new digital TV transmitters

At IBC2004, Screen Service Italia featured a new generation of digital television transmitters with a high degree of integration for multi-frequency networks or single frequency networks according to DVB-T standards.

Starting from the input transport stream, the exciter generates a high-quality OFDM RF signal.

The integrated SFN interface permits operations in precision offset conditions with frequency lock onto the GPS reference signal and compensation for the network delay.

All of the transmitters have double ASI or LVDS inputs to allow maximum flexibility, also in hierarchical mode.

The generation and transmission of COFDM signals at 2k or 8k is possible with QPSK, 16QAM or 64QAM modulation with payloads from 3.73- to 31.67Mb/s.
