Media delivery system and a portable communications module for audio and remote control of interactive toys or devices
First Claim
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
whereinthe 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.

Abstract
A portable communications module (600) of FIG. 6 has an input (621) coupled to receive an incident signal. The input (621) split out a first audio channel containing a context audio track from the incident signal and directs the first audio channel along a first audio output path for selective audio output from a speaker (634, 620) either internally within or external to the module. The input (621)also directs a second audio channel in the incident signal to an RF 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 segment of each track. The input (621) is further arranged to apply a tone encoded signal in the incident signal to at least a tone decoder (640) in a data transmitter chain distinct from the audio transmitter chain (642). A microcontroller (650), responsive to recovered data, is arranged to translate the recovered data into a control signal related to functional control of remote equipment (102). And a data transmit chain (660) operates to modulate the control signal onto a carrier for broadcast to the remote equipment to effect its operational control. The tone encoded data is effectively filtered within the portable communications module to an extent that it is not amplified within the first audio output path and is not processed by the RF audio transmitter chain.
