MPEG-2 SDI Encoder

LMSE

Lightem Systems LMSE series is a multi-functional MPEG-2 encoder. It supports SDI/CVBS and audio input, and converts into two channels of ASI or IP. The input is compressed as MPEG-2 MP@ML format, with coder real-time encodes and multiplexing according to MPEG-2 format, which in turn generating DVB transport stream. It completely complies MPEG-2 standard.
