The ISMUX-004 multiplexer delivers in its output a BTS (Broadcast Transport Stream) generated from the combination of up to eight TS (Transport Streams) inputs. It performs PID filtering and remapping, besides enabling the transmission of interactivity, closed caption and EPG.

The ISMUX controls transmission parameters, such as hierarchical layers settings - number of segments, convolutional code rate, modulation and time interleaving-guard interval and operation mode.
