Abstract

An example playback device may store an active volume state variable in memory, where the active volume state variable corresponds to a current playback volume. The playback device may also store a volume limit state variable in memory, where the volume limit state variable corresponds to a playback volume limit of the playback device. The playback device may detect a command to begin playback of media from a given source and then select a startup playback volume to be one of the current playback volume and the playback volume limit based on the given source of the command to begin playback. The playback device may then play back media at the startup playback volume.

First claim

We claim:

1. A playback device comprising:
a processor;
a non-transitory computer-readable medium; and
program instructions stored on the non-transitory computer-readable medium that, when executed by the processor, cause the playback device to perform functions comprising:
storing an active volume state variable in memory, wherein the active volume state variable corresponds to a current playback volume;
storing a volume limit state variable in memory, wherein the volume limit state variable corresponds to a playback volume limit of the playback device;
detecting a command to begin playback of media from a given source;
determining an identity of the given source of the command to begin playback, wherein the determined identity of the given source comprises a given sensor of a given device;
based on the determined identity of the given source of the command to begin playback, selecting a startup playback volume to be one of the current playback volume and the playback volume limit; and
playing back media at the startup playback volume.

2. The playback device of claim 1 , wherein the given device is the playback device and the given sensor is a touch sensor located on the playback device.

3. The playback device of claim 1 , wherein the volume limit state variable is a maximum volume state variable, and the playback volume limit is a maximum playback volume, and wherein the program instructions, when executed by the processor, further cause the playback device to perform functions comprising:
determining that the active volume state variable is greater than the maximum volume state variable, and wherein the selected startup playback volume is the maximum playback volume.

4. The playback device of claim 1 , wherein the volume limit state variable is a maximum volume state variable, and the playback volume limit is a maximum playback volume, and wherein the program instructions, when executed by the processor, further cause the playback device to perform functions comprising:
determining that the active volume state variable is not greater than the maximum volume state variable, and wherein the selected startup playback volume is the current playback volume.

5. The playback device of claim 1 , wherein the playback device is part of a media playback system comprising a plurality of playback zones and a control device, wherein the playback device is in a first playback zone, wherein the given device is the control device and the given sensor is a touch sensor on the control device, and wherein the program instructions, when executed by the processor, further cause the playback device to perform functions comprising:
determining that the control device is within a second playback zone; and
based on the determination that the control device is within the second playback zone, adjusting the volume limit state variable.

6. The playback device of claim 1 , wherein the program instructions, when executed by the processor, further cause the playback device to perform functions comprising:
detecting a command to pause play back of media from the playback device;
based on the detected command to pause play back of media (1) pausing playback of media from the playback device, and (2) determining a first time corresponding to the command to pause playback of media; and
based on the detected command to begin playback of media, (1) determining a second time corresponding to the command to begin playback of media, and (2) determining that a difference between the first time and the second time exceeds a threshold pause time period.

7. The playback device of claim 1 , wherein the program instructions, when executed by the processor, further cause the playback device to perform functions comprising:
detecting a command to pause play back of media from the playback device;
based on the detected command to pause play back of media, (1) pausing playback of media from the playback device, and (2) determining a first time corresponding to the command to pause playback of media; and
based on the detected command to begin playback of media, (1) determining a second time corresponding to the command to begin playback of media, and (2) determining that a difference between the first time and the second time does not exceed a threshold pause time period.

8. A playback device comprising:
a processor;
a non-transitory computer-readable medium; and
program instructions stored on the non-transitory computer-readable medium that, when executed by the processor, cause the playback device to perform functions comprising:
storing, by the playback device, a maximum volume state variable corresponding to a maximum playback volume of the playback device;
detecting, while the playback device is in a paused state for play back of media, a command received from a given source to increase the playback volume of the playback device to a proposed playback volume;
determining an identity of the given source of the command to increase the playback volume, wherein the determined identity of the given source comprises a given sensor of a given device;
determining an active volume state variable based on (1) the determined identity of the given source and (2) a comparison of the proposed playback volume to the maximum volume state variable, wherein the active volume state variable corresponds to a current playback volume; and
storing the active volume state variable in memory.

9. The playback device of claim 8 , wherein the given device is the playback device and the given sensor is a touch sensor located on the playback device.

10. The playback device of claim 8 , wherein the program instructions, when executed by the processor, further cause the playback device to perform functions comprising:
determining that the proposed playback volume is greater than the maximum volume state variable, and wherein the current playback volume is the maximum playback volume.

11. The playback device of claim 8 , wherein the program instructions, when executed by the processor, further cause the playback device to perform functions comprising:
determining that the proposed playback volume is not greater than the maximum volume state variable, and wherein the current playback volume is the proposed playback volume.

12. The playback device of claim 8 , wherein the program instructions, when executed by the processor, further cause the playback device to perform functions comprising:
detecting a command to begin playback of media; and
based on the command to begin playback of media, playing back media at the current playback volume.

13. A method comprising:
storing, via a playback device, an active volume state variable in memory, wherein the active volume state variable corresponds to a current playback volume;
storing, via the playback device, a volume limit state variable in memory, wherein the volume limit state variable corresponds to a playback volume limit of the playback device;
detecting, via the playback device, a command to begin playback of media from a given source;
determining, via the playback device, an identity of the given source of the command to begin playback, wherein the determined identity of the given source comprises a given sensor of a given device;
based on the determined identity of the given source of the command to begin playback, selecting, via the playback device, a startup playback volume to be one of the current playback volume and the playback volume limit; and
playing back, via the playback device, media at the startup playback volume.

14. The method of claim 13 , wherein the given device is the playback device and the
