Product Overview
This all-in-one devices which integrate encoding (MPEG-2 HD/SD, MPEG-4/AVC H.264 HD/SD) and modulating to convert V/A signals into Digital RF output. It has equipped with 4 HDMI (4 SDI optional) channels input and 1 ASI input and output with 2 ASI ports and 1 IP (4*SPTS or 1 MPTS) output over UDP, RTP/RTSP through data port.
The latency problem has been greatly reduced to achieve an extremely low value from the encoding progress to the decoding terminals.
It adopts inner drawer-type structural design which greatly facilitates the change of encoding modules (HDMI/SDI /…) as needed.
The signals source could be from satellite receivers, closed-circuit television cameras, Blue-ray players, and antenna etc. Its output signals are to be received by DVB-C TVs or STBs and etc
