APPLICATION IN LMDS

    The example of application "CryptOn" system in LMDS networks is ТРС "Trophy" (manufacturer - a company "TROPHY").
    In contrast to the cable TV networks, and also to the networks with application of MMDS, in LMDS networks a standard satellite analog tuner, equipped with the connector "DECODER" for connection of the decoder, is used to receive standard radio signal.
    The renewal of the coded television signals is fulfilled by decoders model DV-01. In this model sync pulses renewal is carried out in modified video signal of the image (In contrast to the decoders model DRA, where sync pulses renewal is implemented in a modified radio signal).
    To work in a mode of the renewal of the modified video signal it is necessary
(Figure 1):
  • to connect decoder to the connector "DECODER" of the tuner;
  • to connect decoder power supply adapter to the power supply of the step-down converter;
  • to switch tuner to a mode of work with the decoder ( to a mode "Decod On").
