Power increase based on packet type
Techniques for controlling one or more audio amplifiers in or associated with a device coupled on a local area network are disclosed. An example playback device includes a processor, an amplifier, a network interface, and a memory. The memory includes a software module that, when executed by the processor, causes the playback device to: operate in a first power mode in which the amplifier consumes a first amount of power; while operating in the first power mode, detect that the playback device received, via the network interface, a specified type of data packet; and based on determining that the playback device received the specified type of data packet, transition from operating in the first power mode to operate in a second power mode in which the amplifier consumes a second amount of power, wherein the first amount of power is less than the second amount of power.
1. A playback device comprising:
a processor;
an amplifier;
a network interface; and
tangible, non-transitory, computer-readable memory comprising instructions that, when executed by the processor, cause the playback device to:
operate in a first power mode in which the amplifier consumes a first amount of power;
while operating in the first power mode, receive one or more packets addressed to the playback device via the network interface and determine that the one or more received packets comprises a specified type of data packet; and
after determining that the one or more received packets comprises the specified type of data packet, transition from operating in the first power mode to operating in a second power mode in which the amplifier consumes a second amount of power, wherein the first amount of power is less than the second amount of power.
2. The playback device of claim 1 , wherein the specified type of data packet is a data packet associated with an audio source.
3. The playback device of claim 1 , wherein the specified type of data packet is a data packet received from an audio source.
4. The playback device of claim 1 , wherein the amplifier comprises an analog circuit.
5. The playback device of claim 1 , wherein the specified type of data packet comprises audio content from an audio source.
6. The playback device of claim 1 , wherein the specified type of data packet comprises a packet of an audio stream from an audio source.
7. The playback device of claim 1 , wherein the specified type of data packet comprises a control packet that comprises control information relating to an audio stream from an audio source, wherein the control packet is received from one of the audio source or a computing device separate from the audio source.
8. The playback device of claim 1 , wherein the specified type of data packet comprises a control packet comprising a command to start playback of an audio stream.
9. The playback device of claim 1 , wherein transitioning from operating in the first power mode to operating in the second power mode comprises switching at least one electronic connection.
10. The playback device of claim 1 , wherein the first amount of power is no power.
11. The playback device of claim 1 , wherein the first amount of power is greater than no power.
12. A method comprising:
a playback device operating in a first power mode in which an amplifier of the playback device consumes a first amount of power;
while operating in the first power mode, the playback device (i) receiving one or more packets addressed to the playback device, and (ii) determining that the one or more received packets comprises a specified type of data packet; and
after determining that the one or more received packets comprises the specified type of data packet, the playback device transitioning from operating in the first power mode to operating in a second power mode in which the amplifier consumes a second amount of power, wherein the first amount of power is less than the second amount of power.
13. The method of claim 12 , wherein the specified type of data packet is a data packet associated with an audio source.
14. The method of claim 12 , wherein the specified type of data packet comprises audio content received from an audio source.
15. The method of claim 12 , wherein the specified type of data packet comprises a packet of an audio stream from an audio source.
16. The method of claim 12 , wherein the specified type of data packet comprises a control packet comprising a command to start playback of an audio stream from an audio source, wherein the control packet is received from the audio source or a computing device separate from the audio source.
17. The method of claim 12 , wherein the second amount of power is greater than no power.
18. A tangible, non-transitory computer-readable storage medium having stored therein instructions executable by one or more processors, wherein the instructions, when executed by the one or more processors, cause a playback device to perform a method comprising:
operating, the playback device in a first power mode in which an amplifier of the playback device consumes a first amount of power;
while operating in the first power mode, the playback device (i) receiving one or more packets addressed to the playback device and (ii) determining that the one or more received packets comprises a specified type of data packet; and
after determining that the playback device received the specified type of data packet, the playback device transitioning from operating in the first power mode to operating in a second power mode in which the amplifier consumes a second amount of power, wherein the first amount of power is less than the second amount of power.
19. The tangible, non-transitory computer-readable storage medium of claim 18 , wherein the specified type of data packet is a data packet associated with an audio source.
20. The tangible, non-transitory computer-readable storage medium of claim 18 , wherein the specified type of data packet comprises control information relating to an audio stream from an audio source, wherein the control information is received from one of the audio source or a computing device separate from the audio source.
21. The tangible, non-transitory computer-readable storage medium of claim 18 , wherein the specified type of data packet comprises a control packet comprising a command to start playback of an audio stream.
