ST-8631 ST8631 is a transponder that converts DVB signals into IP signals or DVB-T signals. It receives the programs of up to two channels or transponders, selects the programs they need and packs them into a new data stream, pushes the IP stream, or re-modulates it into a DVB-T signal and sends it out. This machine can directly configure the parameters by the buttons, or connect to the network through the Ethernet port and use the PC-side tools for quick configuration. It can also group multiple machines into a network, and realize remote monitoring and setting through the Ethernet network. Order
