MPEG Transcoder
DMT-9724T

DMT-9724, it is professional MPEG transcoder which converts from MPEG-2 to MPEG-4 AVC or MPEG-4 AVC to MPEG-2 as Digital stream(DVB-ASI). Also, it receives various broadcasting signals and transcodes Video/Audio streams. As an option, it receives IP stream, RF(8-VSB, QAM, DVB-T, DVB-S) and modulate many kinds of broadcasting signals after transcoding.

· Any to Any real time Video/audio trans-coding
· Supports 4:2:2/4:2:0 (10bit/8bit) video
· Excellent Audio trans-coding
· Audio leveling adjustment
· Flexible modular and scalable architecture to fit your
   network.
· Up to SD / HD channels in the 1RU chassis
· Low power consumption
· Excellent transcoded video quality
· Audio pass-through
· Input : DVB-ASI, IP Stream
         RF(8-VSB, QAM, DVB-T, DVB-S) options

· Output : HDMI, HD/SD-SDI, IP Stream
             Composite, Component (option)
             RF(8-VSB, QAM, DVB-T, DVB-S) options
