METHOD AND APPARATUS FOR PROCESSING A DIGITAL DATA STREAM

摘要

The invention provides for a method and apparatus for of processing digital data (10), comprising the steps of forming a plurality of discrete bursts of data (12) from the digital data, charging a charge storage device (32) during periods (14) between the discrete bursts of data, and subsequently discharging the charge storage device (32) during the discrete bursts of data (12) so as to provide at least part of the power required during the data bursts (12) and so as to reduce peak power requirements while allowing for the transfer of data at rates less than a minimum data rate set for data recordal/playback.
