QuestTel's B-SDI-ASI-IP-4CH - MPEG2/H.264 HD Encoder is a new professional HD audio video encoding device with powerful functionality. It has equipped with 4 SDI channels input supporting MPEG2 and MPEG-4 AVC/H.264 video encoding and MPEG-1 Audio layer 2, LC-AAC, HE-AAC and DD AC3 audio encoding. The 4 encoded programs will output through ASI and IP ports in MPTS or SPTS. It adopts inner drawer-type structural design which greatly facilitates the change of encoding modules to HDMI if needed.
