TBS8112 is a compact trans-modulation device that is used to convert free DVB-S/S2/S2X satellite TV channels to DVB-T (Digital Terrestrial Television) format. It supports to receive free satellite channels from 4 frequencies via 4 RF port, and output DVB-T channels in 4 frequencies.

To meet customers' various requirements, TBS8112 DVB-S/S2/S2X to DVB-T trans-modulator also supports IP streams input and local video file storage. With "Remux" technology, you can randomly select required channels from input streams or local video files, then multiplexed to a new TS stream and output in 4 DVB-T Frequencies.

TBS8112 DVB-S/S2/S2X to DVB-T trans-modulator supports NMS system, can be controlled and configured via Ethernet using a standard browser.
