Compact Dual Channel HDTV Modulator 


Thor’s dual channel compact encoder modulators are designed for high density digital HDTV channel generation.  These systems accept video inputs in all standard HD or SD formats, including component, composite, or HDMI.  In addition they also support all other advanced functions normally found on larger 19 in rack systems.  Their compact form factor is designed to be a table top/desk mount installation.  Supported features include support for HDCP, closed captioning (608 on analog RCA), independant audio input apart from HDMI for audio.  For convenience all functions can be set via a keypad and LCD display located on top of the unit.  However the ideal method for configuration is provided through any standard web browser.  Two Ethernet network ports are provided, one for configuration and a second for IPTV output.  IPTV output is provided in the form of UDP unicast or multicast address outputs with two addresses for single program SPTS outputs and a single address for the combined multi program MPTS stream.  For broadcasters, both ASI input and output are provided on BNC terminals.  HDTV output is provided on standard 75 ohm Type-F connectors with adjustable RF output power level. The H-2ADHD also is capable of modulating both standards of QAM and ATSC, using the highly functional NMS GUI you’re capable of using either standard without reprogramming the unit. Contact a sales representative for more information.

Question and Answers
Yes, we do, the HDMI to ASI converter is actually MPEG2 or H.264 Video encoders https://thorbroadcast.com/product/1-4-hdmi-to-qam-modulators-and-iptv-streaming-encoders-8230.html/12 HDMI-QAM-IPLL unit is an HDMI encoder and will output video to ASI We have also 2ch HDMI or 4 channel HDMI to ASI They take 2 or HDMI inputs, encoders it MPEG2 or H.264, in mux you can choose one TS or second or muxed together as MPTS on the ASI output. The units have also IPTV outputs, SMTP's or MPTS multicast / unicast - UPD, RTP, RTSP This is the link: https://thorbroadcast.com/product/2-hdmi-ypbpr-hd-digital-tv-modulator-qam-atsc-dvb-t-8230.html
Yes, that is correct. 
Only some of our modulators, typically the more high end models have those specific chipsets which allow multiple programs on a single RF channel / carrier. 
So if you are looking to put at least 2 HD channels or perhaps 4 SD channels on the same RF carrier, then those would be the models you'd want to look at. 
The 4ADHD is an advanced model and has more in depth and intuitive NMS Gui's that allow you to do that. 
You just have to stay within the constraints of RF QAM bandwidth, and those units allow you to set the Mbps output per program. 
All data sheets, manuals, and specs can be found on their independent webpages. 

Yes, the encoder can output either UDP or RTP unicast or multicast streams, depending on your preference. For example, for CH 1 multicast IP streaming, the address is on port 2234. On the VLC player, you can access this stream by typing the following syntax: udp://@ You can access that video anywhere on the LAN network if the IGMP protocol is enabled on the switches. You can also access it on any IP STB, like this one:

Thank you for your inquiry. I've reviewed your scenario and have a question: 

What is the reason for needing to go from HDMI to NDI Converter -> NDI Sienna Digital Matrix -> RTSP stream -> RTSP to CATV RF? 

Why can you not go directly from HDMI to CATV RF? I believe there are too many unnecessary steps in your current setup.

Using just HDMI modulators would be much less complex and more immune to failures.

 Please take a look at this product and the accompanying simple application drawing, and let me know if that would work for you:

In case you Must to go RTSP to CATV RF, than we would need need to decode each RTSP sremm to HDMI anyway and use the same H-HDCOAX-8 modulator
We do not have ability to go directly from RTSP to CATV
We could do that if you would have UDP multicast streams using this unit : (but not RTSP)
