Program Decoding to HD-SDI, HDMI, YPbPr, & CVBS with Toslink and XLR audio 

Thor H-HD-IRD series Integrated Receiver Decoders have several applications for decoding program content to broadcast quality video.  Equipped with every major video signal output, including HD-SDI, Thor H-HD-IRD units can provide HD video to any display or professional video system.  Also available are modern digital audio outputs on both optical Toslink and XLR connectors.  Dolby AC/3 audio pass through is standard, and closed caption support for both 608 and 708 captioning systems is present.  The V3 platform adds a front panel LCD video display for confidence monitoring, as well as an internal program multiplexer for combining content from both ASI and IP sources simultaneously.  The web interface displays all available programs and corresponding PID's.  Each program can be independently added to either the ASI or IP outputs. 

 All selected programs are multiplexed into a single MPTS output.  Additionally, the IP output can be configured for up to 32 SPTS single program stream outputs, each with different address and port settings.  This allows the V3 system to be used as an intelligent ASI to IP or RF to IP Gateway with add drop and ASI video signal multiplexing capabilities.  Combined multi program transport streams carried over IP can also be separated into their corresponding single program streams.  The RF tuner can be configured for QAM, 8VSB (ATSC), DVB-T, DVB-C, or DVB-S2 signal sources.  Two CAS card slots allow decoded of encrypted programing. 

Thor HD-IRD units can be used for converting broadband programing to uncompressed HD video, as well as multiplexing and retransmitting programs to both ASI and IP outputs.  Thor HD-IRD systems are a reliable and versatile platform for broadcast program decoding and TS protocol conversion

Question and Answers
We have 2 ways to do it.
First H-NVS3500 is a SDI RTSP encoder/decoder, design to reliable send SDI over the public internet, doesn't requires big bandwidth to do it, just about 3Mbps
You would need to use 4pcs to do 2 Videos; 2 as encoders, 2 as a decoders
Or the secound option:
1pcs 2 x SDI encoder H-2SDI-QAM-IPLL  2 SDI input IP streams output
2pcs IRD decoder H-IRD-V3s IP input SDI output
The only way we can do DVBS-S2 to SDI would be using the H-IRD-V3s IRD decoder.
This is a multifunction device with a lot of different futures, one of them is DVBS-S2 to SDI /HDMI / CVBS video output.
It does have CI slot for the CI card, Common Interface (also called DVB-CI) is a technology which allows decryption of pay TV channels.
The Common Interface allows TV manufacturers to support many different pay TV stations, by allowing to plug in exchangeable conditional-access modules (CAM) for various encryption schemes.

We do have a solution for integrated Video encoder and satellite DVB-S/2 modulator
please check these links:
SDI or HDMI Encoder / DVBS-s 2 modulator, that will be installed in your Transmitting Site
On the Receiving side, you can use Sat IRD to receive and decode sat signal to HDMI or SDI
Please see those links and specifications and let me know if that would work for you
You can use 1 IRD, but you would be able to get video from one or the other encoder or you could use 2 IRD's to receive both feeds at the same time
Yes, that is correct. The 8VSB will take the entire frequency and all data within it and output to the ASI. 
So if you have any subchannels, data like closed captions etc, everything will be passed onto the ASI TS.
