The 4 HDMI and Component HD to Coax Modulator and IPTV Encoder Streamer from Thor provides five 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 four video streams up to 1080p60 each. You can adjust the bit rate from 1.5 to 19 Mb/s. It provides standard audio encoding in MPEG-2 AAC and MPEG-4 AAC, as well as a licensed Dolby AC/3 audio codec. You can select the audio sources from either embedded HDMI or analog RCA ports.

For surround sound, digital audio inputs can be set to "pass-through" mode to preserve 5.1 and 7.1 audio encoded already in Dolby compatible format. Two mirrored ASI outputs are provided for broadcasters for distributing the content generated by the four encoders. Programs input via ASI can also be multiplexed and remapped to the ASI output, adding yet another function to the unit as an ASI multiplexer. 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 rate (CBR) packet.

All four channels can be independently configured for either multicast or unicast outputs, while the closed captioning is supported on a dedicated analog 608 CC port with RCA connector. Any 720 or 1080 line standard video signal in either HDMI or component format can be used for each of the four channels. This system can be configured with firmware for either QAM, DVB-C, DVB-T, or ATSC channel format output.
