Thor DVB-S/S2 Encoder & Modulator is an integrated HD Video Encoder with the sattelitte S2 modulator. Hot- swapable modules with diferent video inputs  (CVBS/SDI/HDMI/YPbPr…) are available.

It has also 1 channel ASI input for external  TS (MPEG2 or H.264) multiplexing  . It outputs ASI and DVB-S/S2 RF (IF Optional) simultaneously.

The signal source could be SDI camera, HDMI Blue-ray players and etc. It has web-based NMS GUI interface for easy online management.

Featuring its high performance and low cost, the S2 is especially used by TV stations or DSNG systems to encode SD/HD programs and output to uplink.

Question and Answers
1) If that encoder needs to support 4:2:2, then we can do via external encoder : this is the only way we can do it, 2 separate units, one as an encoder second as a modulator H-MPEG2-H264-E2 , SDI input -ASI output, ( support 4:2;2) H-1SDI-DVBS2 DVBS2 Modulator ASI input - L-band Output 2) Yes, that is why you need both pieces, one unit to encode in 4 2 2 and the other unit takes a TS from the encoders ASI and modulates it to an RF channel.
