Abstract
A number of ones in the difference between a current pulse code modulated (PCM) audio sample and an immediately preceding audio sample is compared to a number of ones in the current audio sample to determine which has the fewer number of ones. The audio source sends either the difference or the current audio sample, whichever has fewer ones. By reducing the number of ones sent over a non-return to zero inverted (NRZI) audio bus from an audio source to an audio sink, the number of transitions is reduced, which reduces the power consumed relative to a transmission that does not use this process.
