One-bit run-length encoding and playback system
First Claim
Patent Images
1. An audio recording system, comprising:
- a one-bit converter for generating a plurality of channels of digital audio data from one or more external sources;
means for interleaving the plurality of channels into a run-length data stream, wherein the run-length data stream comprises a series of binary values indicating run-length lengths for each of the channels of digital audio data; and
an input interface for accepting timing and control data associated with the audio data;
means for inserting control and synchronization markers derived from the timing and control data into the run-length data stream, so that the digital audio data may be correctly located upon playback.

10. An audio playback system, comprising:
-
means for receiving a plurality of channels of digital audio data interleaved into a run-length data stream, wherein the run-length data stream comprises a series of binary values indicating run-length lengths for each of the channels of digital audio data; means for removing control and synchronization markers from the run-length data stream and for using the removed control and synchronization markers to control the playback of the run-length data stream; means for reconstructing the plurality of channels of digital audio data interleaved into the run-length data stream; and means for transmitting the reconstructed plurality of channels of digital audio data to an one-bit decoder, wherein the one-bit decoder recreates analog signals from the digital audio data to drive a plurality of audio transducers. - View Dependent Claims (11, 12, 13, 14, 15, 16)
