Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
105 words
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.
Claim 2
Dependent Claim
105 words
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.
Claim 3
Dependent Claim
16 words
The audio recording system of claim 1, further comprising means for compressing the run-length data stream.
Claim 4
Dependent Claim
16 words
The audio recording system of claim 1, further comprising means for encrypting the run-length data stream.
Claim 5
Dependent Claim
21 words
The audio recording system of claim 1, further comprising means for storing the run-length data stream on a data storage device.
Claim 6
Dependent Claim
16 words
The audio recording system of claim 1, further comprising means for transmitting the run-length data stream.
Claim 7
Dependent Claim
24 words
The audio recording system of claim 1, wherein the one-bit converter accepts both analog and digital signals and generates the digital audio data therefrom.
Claim 8
Dependent Claim
18 words
The audio recording system of claim 1, wherein the one-bit converter generates pulse density modulated digital audio data.
Claim 9
Dependent Claim
24 words
The audio recording system of claim 1, wherein the digital audio data has only two levels comprising a logical one and a logical zero.
Claim 10
Dependent Claim
21 words
The audio recording system of claim 1, wherein the run-length data stream comprises a synchronizing portion and the run-length data portion.
Claim 11
Dependent Claim
128 words
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.
Claim 12
Dependent Claim
128 words
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.
Claim 13
Dependent Claim
16 words
The audio recording system of claim 10, further comprising means for de-compressing the run-length data stream.
Claim 14
Dependent Claim
16 words
The audio recording system of claim 10, further comprising means for de-encrypting the run-length data stream.
Claim 15
Dependent Claim
21 words
The audio recording system of claim 10, further comprising means for retrieving the run-length data stream from a data storage device.
Claim 16
Dependent Claim
20 words
The audio recording system of claim 10, further comprising means for receiving the run-length data stream from a transmitting device.
Claim 17
Dependent Claim
21 words
The audio recording system of claim 10, wherein the run-length data stream comprises a synchronizing portion and the run-length data portion.
Claim 18
Dependent Claim
30 words
The audio recording system of claim 15, wherein the synchronizing portion comprises inserted control and synchronization markers that a timeline for an audio program embedded in the run-length data stream.
