The H-4ADHD-XXX-IPLL modulator family from Thor broadcast is designed to handle even more applications than any other 4 channel chassis system that has come before.  This system has all the previous award winning features found in Thor Broadcast modulators, as well as several new additional functions for added applications and flexibility.  The platform provides 5 full RF carrier outputs for generating channels from content ingested through the ASI input.  Encoding in either MPEG-2 or H.264 is provided for 4 crystal clear video streams up to 1080p60 each.<br><br>Bitrate is fully adjustable from 1.5 - 19 Mbps, and a variety of audio codecs are available.  Standard audio encoding in MPEG-2 AAC and MPEG-4 AAC are provided, as well as a licensed Dolby AC/3 audio codec.  Audio sources can be selected from either embedded HDMI or Analog RCA ports.

IPTV is not neglected in any way.  All four encoded programs can be mapped to unique IP address outputs and ports in either UDP or RTP format.  The IP output can be configured to strip null packets to reduce network bandwidth or preserve the constant bit rat (CBR) packet stuffing normally preferred by television systems.  All four channels can be independently configured for either multicast or unicast outputs.  Closed captioning is supported on a dedicated analog 608 CC port with RCA connector, an industry standard for line 21 captioning systems.  Any 720 or 1080 line standard video signal in either HDMI or Component YPbPr format can be used for each of the four channels.  Just like all other professional Thor modulator chassis, this system can be configured with firmware for either QAM, DVB-C, DVB-T, or ATSC channel format output.<br><br><br>Features<br><br>Broadcast over existing Coaxial Cabling to an unlimited number of Televisions with FULL HD<br>Broadcast Live HDMI & YPbPr Video as Cable TV & IPTV Channels.<br>Licensed HDMI inputs - works with any source like DVD, Blu-Ray, or any STB<br>Convert HDMI & Component YPbPr HD Video to HDTV Channels<br>Any 1-4 HDMI & YPbPr Inputs up to 720p / 1080i / 1080p<br>Licensed HDMI inputs - works with any source like DVD, Blu-Ray, or any STB<br>4 HDMI Cables FREE<br>Support DD AC3 (2.0 / 5.1 / 7.1) passthrough (for HDMI interface only)<br>Support CC (Closed Caption) EIA608 (from CVBS input)<br>1-4 CATV RF Output up to 4 Adjacent channels<br>QAM-256/64, DVB-T & ATSC formats available<br>Fully IP Control and Network Management through browser<br>Front Panel LCD local control   <br>IPTV Output Unicast or Multicast IGMP UDP, RTP / RTSP<br>ASI Output multiplexer with cherry picking<br>Low Latency available 70-120ms<br>Dolby AC3 or MPEG1/2 Audio Encoding<br>MPEG2 or MPEG4 H.264 Video Encoding<br>Firmware for ATSC, DVB-T, DVB-S2 Available<br>VCT (Virtual Channel Table) support for DVB-C and ATSC<br>LCN (Logical Channel Number) support<br>5 Years warranty
