This cranscoderconverts MPEG Video and Audio format directly from the RF input.

The RF input can be ATSC or QAM or sateliteDVBS 2 , it has also IP and 2 ASI inputs.

Thranscoderd ouputis via ASI and IP SMPTS's 

This transcoder supports advanced re-multiplexing and can effectively provide operators with real-time code rate switch and optimize the video with its high performance.
BISS function is now embedded to descramble Tuner and IP input programs and CC function as well to transport your closed caption (or teletext).
It can be easily managed through web NMS system, and has become an ideal solution for operator to provide high quality video trans-coding.

Question and Answers
Yes, The transcoder can do that, altrought please note that it can Transcode up to 8 SD TS's or only 4 HD TS's
How many TS programs (Videos) do you need to do in total?
The other way would be decoding each ATSC program into the HDMI and using an 8ch Full HD HDMI modulator.

Therefore, you could use simple 8 ATSC to HDMI decoders with an 8-channel modulator. the modulator support MPEG Audio

This is the link to 8ch HDMI modulator
This is the link to ATSC to HDMI decoder STB
