Audio data buffering
First Claim
1. A method of buffering audio data in an audio playback system that is adapted to receive and playback separate, discrete audio files from one or more audio sources, where the audio files comprise audio data, and where the audio playback system comprises a master device that receives audio files from the one or more audio sources, buffers the received audio data, and distributes the buffered audio data to one or more active slave audio playback devices, the method comprising:
- requesting, by the master device, a first discrete audio file from an audio source;
receiving, by the master device, the first discrete audio file;
buffering, by the master device, audio data from the received first discrete audio file; and
sending, by the master device, buffered audio data from the received first discrete audio file to the one or more active slave audio playback devices; and
during synchronized playback by the master device and the one or more active slave devices of the audio data from the first discrete audio file, sequentially performing each of the following steps;
requesting, by the master device, a second discrete audio file from an audio source;
receiving, by the master device, the second discrete audio file;
buffering, by the master device, audio data from the received second discrete audio file; and
sending, by the master device, buffered audio data from the received second discrete audio file to the one or more active slave audio playback devices.

Abstract
A method of buffering audio data in an audio playback system that is adapted to receive and playback separate, discrete audio files from one or more audio sources, where the audio files comprise audio data, and where the audio playback system comprises a master device that receives audio files from a source, buffers the received audio data, and distributes the buffered audio data to one or more active slave audio playback devices. The master device requests a first audio file from an audio source, receives the first audio file, buffers audio data from the first audio file, and sends buffered audio data from the first audio file to one or more active slave audio playback devices. During playback of the audio data from the first audio file, the master device requests a second audio file from an audio source, receives the second audio file, buffers audio data from the second audio file, and sends buffered audio data from the second audio file to one or more active slave audio playback devices.

11. A method of buffering audio data in an audio playback system that is adapted to receive and playback separate, discrete audio files from a plurality of different audio sources, where the discrete audio files comprise audio data, and where the audio playback system comprises a master device that receives discrete audio files from the sources, buffers the received audio data, and distributes the buffered audio data to one or more active slave audio playback devices, wherein the master device and the one or more active slave audio playback devices have internal clocks, and wherein audio data is played back by both the master device and the one or more active slave audio playback devices, the method comprising:
-
requesting, by the master device, a first discrete audio file from a first audio source;
receiving, by the master device, the first discrete audio file;
buffering, by the master device, audio data from the received first discrete audio file; and
sending, by the master device, buffered audio data from the received first discrete audio file to the one or more active slave audio playback devices;as soon as the master device finishes receiving the first discrete audio file, sequentially performing each of the following steps; requesting, by the master device, a second discrete audio file from a second audio source; receiving, by the master device, the second discrete audio file; buffering, by the master device, audio data from the second discrete audio file; and sending, by the master device, the buffered audio data from the second discrete audio file to the one or more active slave audio playback devices, wherein the master device sends the buffered audio data to the one or more active slave audio playback devices immediately after the received audio data is buffered by the master device; and synchronizing, by the master device, a playback of audio data from the first and second discrete audio files by the master device and the one or more active slave playback devices, wherein synchronizing comprises the master device determining a playback time per the master device internal clock and transmitting the determined playback time to the one or more active slave audio playback devices.
