The professional and highly integrated DTV4647S DTV encoder modulator offers a range of functions in one case, including encoding, multiplexing, and modulation. It can handle up to 8/16/24 HDMI (or HDMI plus DVB-S2/S2X tuner) inputs, 1 ASI input, 1 USB player input, and 128 IP inputs via the GE port, and output through multiple DVB-C channels, with optional DVB-T/ATSC/ISDB-T support. Additionally, it supports MPTS output as a mirror of carriers through the GE port, and has 1 ASI out as a mirror of one of the carriers.

 

This full-function device is well-suited for small CATV head end systems, and is a smart choice for hotel TV and entertainment systems in sports bars, hospitals, and apartments. Other features of the DTV4647S include MPEG-4 AVC/H.264 video encoding, 1 ASI input for re-muxing, 128 IP input over UDP and RTP via GE port, support for MPEG1 Layer II, LC-AAC and HE-AAC audio encoding, AC3 Pass Through, audio gain adjustment, and support for 12ch DVB-C RF out (with 8ch/16ch DVB-T, 8ch ATSC, or 6ch/16ch ISDB-T outputs as optional).

 

The device can also support 1 ASI out as a mirror of one of the RF output carriers (optional), MPTS IP output over UDP, RTP/RTSP, LOGO, Caption and QR code insertion (with support for languages such as Chinese, English, Arabic, Thai, Hindi, Russian, and Urdu), PID remapping/ accurate PCR adjusting/PSI/SI editing and inserting, and can be controlled via web management, with easy updates via the web.
