Abstract

An example implementation may involve a computing system receiving, from a media playback system, a request for an indication of a playhead pointer for a particular queue of media items. The implementation may also involve the computing system identifying a position of a playhead pointer within the particular queue of media items. Each position in the queue may correspond to a media item. The implementation may further involve the computing system sending, to the media playback system, an indication of the playhead pointer. The indication of the playhead pointer indicates the assigned position of the playhead pointer.

Claims

1. A method comprising:

receiving, by a computing system from a media playback system, a request for an indication of a playhead pointer for a particular queue of media items;

identifying, by the computing system, a position of a playhead pointer within the particular queue of media items, wherein each position in the queue corresponds to a media item; and

sending, by the computing system to the media playback system, an indication of the playhead pointer, wherein the indication of the playhead pointer indicates the assigned position of the playhead pointer.

2. The method of claim 1, wherein identifying a position of a playhead pointer comprises:

generating a playhead pointer configured to indicate a position within a queue; and

assigning the generated playhead pointer to a position in the particular queue of media items

3. The method of claim 1, further comprising:

receiving a media item identifier that indicates a particular media item that the media playback system is to play back; and

wherein assigning the playhead pointer to a position in the particular queue of media item comprises assigning the playhead pointer to a particular position in the queue corresponding to the particular media item that the media playback system is to playback.

4. The method of claim 1, wherein assigning the playhead pointer to a position in the particular queue of media item comprises

receiving, from the media playback system, a request to playback the particular queue of media items at the beginning of the particular queue;

and

assigning the playhead pointer to a particular position that is ordered first in the queue.

5. The method of claim 1, wherein sending the indication of the playhead pointer comprises sending a universal resource identifier that indicates the assigned position of the playhead pointer in the queue of media items.

6. The method of claim 1, wherein sending the indication of the playhead pointer comprises sending an indication of the playhead pointer that causes the media playback system to initiate playback of the queue at the assigned position of the playhead pointer.

7. The method of claim 1, further comprising:

receiving an indication of a particular position of a local playhead pointer in a local copy of the queue at the media playback system;

determining that the particular position of the local playhead pointer in the local copy of the queue is different from the assigned position of the playhead pointer; and

re-assigning the playhead pointer to a position in the queue corresponding to the particular position.

8. The method of claim 1, wherein the media playback system includes at least one zone of one or more playback devices configured to play back media items in synchrony, and wherein sending the indication of the playhead pointer comprises sending an indication of the playhead pointer that causes the one or more playback devices of the at least one zone to initiate playback of the queue at the assigned position of the playhead pointer.

9. The method of claim 1, further comprising:

assigning, to a particular device of the media playback system, an owner status, wherein the owner status authorizes the particular device to perform a particular set of operations corresponding to manipulation of the playhead pointer.

10. The method of claim 1, further comprising:

assigning, to a first device of the media playback system, an owner status, wherein the owner status authorizes the first device to perform a first set of operations on the playhead pointer; and

assigning, to one or more second devices of the media playback system, a subscriber status, wherein the subscriber status authorizes the one or more second devices to perform a second set of operations on the playhead pointer, and wherein the second set of operations is different from the first set of operations.

11. The method of claim 1, further comprising:

assigning, to a particular device of the media playback system, an owner status, wherein the owner status authorizes the particular device to perform a first set of operations on the playhead pointer; and

assigning, to one or more respective devices of one or more additional media playback systems, a subscriber status, wherein the subscriber status authorizes the one or more respective devices to perform a second set of operations on the playhead pointer, and wherein the second set of operations is different from the first set of operations.

12. The method of claim 11, wherein the first set of operations corresponds to control of the position of the playhead pointer, and wherein the second set of operations correspond to playback of the queue in synchronization with the playhead pointer.

13. The method of claim 1, further comprising:

receiving, from a control device, an indication of a command to manipulate the assigned position of the playhead pointer;

based on the request, sending to the media playback system, an indication of the command to manipulate the assigned position of the playhead pointer;

after sending the indication of the command to manipulate the assigned position of the playhead pointer, receiving an indication of a new position of the playhead pointer;

re-assigning the playhead pointer to the new position; and

sending, to the control device, an indication that the position of the playhead pointer has been re-assigned.

14. A computing system comprising:

a network interface;

at least one processor;

a data storage; and

a program logic stored in the data storage and executable by the at least one processor to;

receive, from a media playback system, a request for an indication of a playhead pointer for a particular queue of media items;

assign a playhead pointer to a position in the particular queue of media items, wherein each position in the queue corresponds to a media item; and

send, to the media playback system, an indication of the playhead pointer, wherein the indication of the playhead pointer indicates the assigned position of the playhead pointer.

15. A method comprising:

receiving, by a control device of a media playback system, input data that associates a zone of one or more playback devices with a particular queue of media items;

sending, by the control device to a computing system, a request for an indication of a playhead pointer for the particular queue of media items; and

receiving, by the control device, the requested indication of the playhead pointer, wherein the indication of the playhead pointer indicates an assigned position of the playhead pointer in the particular queue of media items, and wherein the assigned position corresponds to a media item at that position in the particular queue.

16. The method of claim 15, further comprising:

cause a graphical interface to display an indication of the assigned position of the playhead.

17. The method of claim 16, wherein causing the graphical interface to display the indication of the assigned position of the playhead comprises causing the graphical interface to display an indication of a media item that corresponds to the assigned position of the playhead pointer in the queue of media items.

18. The method of claim 15, further comprising:

receiving one or more respective messages indicating respective positions of the playhead in the queue of media items; and

upon receiving each message, causing the graphical interface to display an indication of the respective position of the playhead indicated by the message.

19. The method of claim 15, further comprising:

receiving input data indicating a command to manipulate the position of the playhead pointer; and

send, to the computing system, a request to manipulate the position of the playhead pointer according to the command.

20. The method of claim 15, further comprising:

receiving an indication of one or more queues of media items at the computing system; and

causing a graphical interface to display an indication of the one or more queues of media items; and

wherein receiving input data that associates a zone of one or more playback devices with a particular queue of media items comprises receiving input data that associates the zone of one or more playback devices with a particular one of the one or more queues of media items.
