13. A remote control apparatus that receives voice activated commands comprising:
a first microphone;
an enable microphone function configured to activate the first microphone such that the first microphone can receive inputs;
a processor configured to digitize inputs received at the first microphone;
a speech encoder configured to compress the digitized inputs;
a multiplexer configured to multiplex the compressed digitized inputs with control commands to produce a data transport stream comprising a control stream and a speech stream; and
a transmitter configured to wirelessly transmit the data transport stream to a device associated with the remote control apparatus.
