4IN1 MPEG-2 SD Encoder

Overview

4IN1 MPEG-2 SD Encoder supports SD MPEG-2 video and MPEG-1 audio encoding. It has 4×CVBS video, 4 pairs of unbalanced audio and 1×ASI (BNC (MUX)) input interfaces, and can multiplex the input signal (TS) to generate DVB transport stream (TS/ASI) and IP (TS over UDP) output. The encoder suits 1U rack and can be configured by front panel LCD and NMS (network management software).
