DVB Solution

This solution mainly uses IRD and STB acquisition signal as program signal source, uses high-definition encoder to re-encode the signal, multiplex the video data, scramble the program through CAS system, support other CAS with the same cipher, and transmit to the transmitting station after mixed modulation by the modulator.

The following is a diagram of the operation environment of the local network. Program source acquisition can be carried out according to the specific operation program for front-end equipment acquisition. It can use the STB device to capture the program HDMI input to MUX / SCRAMBLER, or an IRD device for acquisition and to transfer programs to the MUX / SCRAMBLER over the network. Figure 1 is the operation system setup diagram, and figure 2 is the internal structure diagram of CAS system. The specific deployment needs to confirm whether it is a distributed or a single deployment based on the current operational environment.
