Portbale IP  QAM Modulator SQE
 
OverView

Scivo's SQE is a portable multi-functional IP-QAM modulate device. It can receive digital video content over UDP/IP and modulate into a DVB compliant QAM signal. So DTV engineer could use SQE to do field development or establish a low-cost mini product demonstration system. The input data stream could be SPTS and MPTS. With powerful processing ability, SQE can multiplex SPTSs to MPTS and insert SI and EPG information. So it is also an ideal solution of compact and low cost for smaller cable operators running their digital video services.
