The QPSK / COFDM Estro conversion head-end allows you to receive satellite services (even encrypted) and tune them to a digital terrestrial decoder or a TV with DTT Tuner. The Sat channels, also coming from different transponders, are converted to a DTT mux chosen by the user and mixed with the normal services received via the terrestrial TV antenna. For each converted channel, it is possible to assign an LCN number. In this way, the user will be able to decide which position the converted channels must occupy in the TV channel list. The series consists of four different models, FTA and with CI, and allows you to convert groups of channels (SD or HD) from different TP to mux DTT. The 80402CI and 80403CI modules can be combined with CAM CI for coded services. Programming is performed via the PC.
