TRD-S COFDM Receiver

      The receiver is used in CCTVs with diversed reception.
      This mode requires two receivers: one of the receivers is assigned as a master receiver and the other one as a slave receiver. Receiver rf inputs are connected to spaced antennas.
      A digital bitstream from the slave receiver output is set to the master receiver input by means of an DVB ASI (C) interface. The analysis of digital bitstreams from two receivers is effected in the master receiver to detect errors and a decision is made which of the bitstreams should be sent to the MPEG decoder for its conversion into video- and audiosignals. Thus there is a possibility of a signal choice from the most undistorted digital bitstream when the slave receiver is used.
      A delivery set includes two receivers.
