Method and system of extending battery life of a wireless microphone unit

摘要

A method of extending battery life of a wireless microphone unit includes muting the wireless microphone unit responsive to a mute signal from a base station unit, transmitting, by the wireless microphone unit, compressed muted audio data, wherein the compressed muted audio data is compressed via a first compression scheme, determining, by the wireless microphone unit, whether an unmute signal has been received from the base station unit, and responsive to a determination that the unmute signal has been received, unmuting the wireless microphone unit. The method further includes discontinuing transmission of the compressed muted audio data and transmitting compressed audio data via a second compression scheme, wherein the first transmitting step causes the wireless microphone unit to consume less power per unit of transmission time than the second transmitting step.

1. A method of extending battery life of a wireless microphone unit, the method comprising:
muting the wireless microphone unit responsive to a mute signal from a base station unit; transmitting, by the wireless microphone unit, run-length-encoded muted audio data; determining, by the wireless microphone unit, whether an unmute signal has been received from the base station unit; responsive to a determination that the unmute signal has been received, unmuting the wireless microphone unit; and wherein the base station unit comprises a recording device configured to record the run-length-encoded muted audio data transmitted by the wireless microphone unit.
