IRIB 3+1 Uplinks

 

This project comprises of 4 encoders, 2 multiplexers, 2 modulators and additional monitoring devices. The uplink accepts 3 channels TV input. At the first stage, compression takes place using EN8030 (MPEG-4) then all the services will be multiplexed into one transport stream using MX5620. This single stream will be modulated by TANDBERG’s SM6625. The output will be sent to the transmission section.

The 3+1 configuration enables the system to handle the situation in the absence of one encoder, one multiplexer and/or one modulator.
