Antik GX 5204 IRD+Encoder / Transmodulator

 

Antik GX 5204 Multireceiver + Encoder / Transmodulator

 

The GX-5204 integrates a 4 DVB input Receiver on input and a Transmodulator or Encoder as output in one 1U 19” chassis. It provides operators with an ideal DTV headend setup solution by combining a multi-channel receiving, descrambling, remultiplexing or encoding.

The DVB QAM/COFDM modulation and TS over IP operations work together in one single unit. The GX-5204 equipped with 4 independent tuner front end with various factory options for DVB-T/T2, DVB-S2/S, DVB-C, DTMB, ISDB-T and ATSC types, and industrial standard ASI and TS/IP inputs outputs, ensures the compatibility with all kinds of transmission media.

High density real-time H.264 HD/SD Encoders use input from dedicated tuner frontent. The encoded streams can be then remultiplexed and output over its GbE IP and ASI ports.

All models support the Time Base Correction (TBC) to ensure the audio and video synchronisation, the features necessary for the professional TV signal flow. The series provide two TS/IP operation modes. The first is “Full Duplex”, which allows one MPTS or SPTS inputted over 1 multicast/unicast to make up a new MPTS with local encoders, then sends out the new one over 1 multicast/unicast.
