Ensemble Multiplexer (1TH-EMUX)

The RadioScape DAB Ensemble Multiplexer enables the generation of a DAB Ensemble Transport Interface (ETI) bit stream in real time by multiplexing together a set of audio and data input streams.

This ETI stream can be configured to conform to either of the two physical layers of the Ensemble Transport Interface ETI (NI, G.703) or ETI (NA, G.704). The Ensemble Multiplexer is linked to the RadioScape Broadcast manager, which provides device control and scheduling functionality.
