TBS8120 is an all-in-one device integrated encoding (MPEG-4/AVC H.264), multiplexing and modulation functions in one standard 1U case. It can convert 12 HDMI signals to 4 DVB-T RF out. The signals source could be from satellite receivers, closed-circuit television cameras and etc. its output signal is to be received by DVB-T standard TVs or DVB-T STBs.

To meet customers' various requirements, this device is also supports IP input and supports 4 MPTS output over IP with UDP/RTP protocol . With "Remux" technology, you can easily select popular channels from input streams, then multiplexed to a new TS stream to 4 RF output.

TBS DVB-T modulator server is the perfect solution for Digital Signage, Private Circuit, STB Testing, and Laboratory Applications. It also provides a very costs-effective solution to transmodulation system and IPTV systems.
