Overview

4EHD14 4 in 1 MPEG-4 AVC/H.264 HD Encoder is a professional HD audio & video encoding and multiplexing device. It has 4 HDMI inputs, supporting MPEG4 AVC/H.264 High Profile coding format. This device is able to encode 4 HD programs at the same time; moreover, it has one ASI input and can multiplex the input TS with the encoded SPTS to output MPTS. The PSI/SI information can be inserted into MPTS output. In conclusion, its high integrated and cost effective design makes the device widely used in various DVB systems.
