Abstract:
1. A portable communications module responsive to an incident signal the portable communications module comprising: an put configured: i) to split out a first audio channel containing a context audio track from the incident signal applied thereto, the input further arrange to direct the first audio channel along a first audio output path for selective audio output of the context audio track from a speaker either integrated with the portable communications module orexternal to the portable communications module; and ii) to direct a second audio channel in the incident sign ral to a wireless audio transmitter chain for broadcast, the second audio channel comprising a composite audio signal from a plurality of audio tracks, each audio track embedded with a unique activation code that is present for substantially an entire duration of audio activity in each audio seoment of each track; and iii) to apply a tone encoded signal in the incident signal to at least a tone decoder in a data transmitter chain distinct from the audio transmitter chain; a microcontroller coupled to the tone decoder, the microcontroller .arranged to interpret and translate the tone into a control signal related to functional control of remote equipment; and a data transmit chain, responsive to the microcontroller, the data transmit chain arranged to modulate the control signal onto a carrier for broadcast to the remote equipment to effect functional control thereof; and wherein the tone encoded data is filtered within the portable communications module to an extent that it is i of amplified within the first audio output path and is not processed by the RF audio transmitter chain.
