The DTV4647S is a powerful device that combines a range of functions into a single case. This device includes encoding and de-modulation, multiplexing, and modulation capabilities. It supports various inputs, including up to 8/16/24 HDMI inputs, 1 ASI input, 1 USB player input, and 128 IP inputs via the GE port. It can output on multiple DVB-C channels, and it also supports MPTS output as a mirror of carriers through the GE port, and 1 ASI out as a mirror of one of the carriers. This makes it perfect for a small CATV head end system and a great choice for hotel TV systems, entertainment systems in sports bars, hospitals, and apartments. It also has MPEG-4 AVC/H.264 video encoding, supports MPEG1 Layer II, LC-AAC and HE-AAC audio encoding, AC3 Pass Through, audio gain adjustment, and supports a variety of languages. Additionally, it supports PID remapping, accurate PCR adjusting, PSI/SI editing and inserting, and can be controlled via web management and updated easily via the web.
