Recently you mentioned that you demonstrated in India multi-DRM signals from a single
FM transmitter. How many can be actually broadcast? (Group of DRM supporters in Vizag, India)
The number of individual DRM signals is only limited by the bandwidth of the transmitter. Every DRM signal can originate from an individual broadcaster, who remains in full control over both content and the on-air configuration (e.g. DRM modulation parameters and content elements).Transmission of up to 6 DRM digital blocks (18 Audio + 6 Multimedia Journaline services) was demonstrated from the VS series Nautel transmitter, which has 600 kHz bandwidth, enabled by the RFmondial DRM modulator.
