Abstract

A video quality module receives data indicating a visibility status of a tab of a web browser running on a user device. The video quality module determines, based on the data indicating the visibility status of the tab whether the tab of the web browser is currently visible to a user of the user device, the tab of the web browser comprising a streaming media player. If the tab of the web browser is not currently visible to the user, the video quality module decreases a quality of a video component of a streaming media file playing in the streaming media player.

Claims

1. A method comprising:

providing, from a media streaming server, a streaming media file to a streaming media player in a first tab of a plurality of tabs of a user interface running on a user device, wherein a second tab of the plurality of tabs comprises content not including the streaming media player;

receiving, at the media streaming server, data from the user device indicating a visibility status of the first tab of the plurality of tabs in the user interface running on the user device;

determining, based on the data indicating the visibility status of the first tab, whether the first tab of the user interface is currently visible to a user of the user device, wherein the first tab is not visible to the user when the second tab of the plurality of tabs is selected; and

if the first tab of the user interface is not currently visible to the user, decreasing, by a processing device of the media streaming server, a quality of a video component of a streaming media file being provided to the user device and playing in the streaming media player, while maintaining a current status of an audio component of the streaming media file.

2. The method of claim 1, wherein the first tab of the user interface is not visible to the user when the first tab is in the background of the user interface, behind one or more other tabs including the second tab.

3. The method of claim 1, further comprising:

halting a transmission of the video component of the streaming media file to the user device; and

continuing to transmit an audio component of the streaming media file to the user device.

4. The method of claim 1, further comprising:

if the first tab of user interface is currently visible to the user, determining if the video component is currently decreased from a default setting.

5. The method of claim 4, further comprising:

if the video component is currently decreased from the default setting, increasing the quality of the video component to the default setting; and

if the video component is not currently decreased from the default setting, maintaining a current quality of the video component.

6. The method of claim 4, wherein the first tab of the user interface is visible to the user if the first tab is in the foreground of the user interface.

7. The method of claim 1, wherein receiving the data indicating the visibility status of the first tab comprises sending a request for the visibility status of the first tab using a page visibility application programming interface of the user interface.

8. A non-transitory machine-readable storage medium storing instructions which, when executed, cause a processing device to perform operations comprising:

providing, from a media streaming server, a streaming media file to a streaming media player in a first tab of a plurality of tabs of a user interface running on a user device, wherein a second tab of the plurality of tabs comprises content not including the streaming media player;

receiving, at the media streaming server, data from the user device indicating a visibility status of the first tab of the plurality of tabs in the user interface running on the user device;

determining, based on the data indicating the visibility status of the first tab, whether the first tab of the user interface is currently visible to a user of the user device, wherein the first tab is not visible to the user when the second tab of the plurality of tabs is selected; and

if the first tab of the user interface is not currently visible to the user, decreasing, by the media streaming server, a quality of a video component of a streaming media file being provided to the user device and playing in the streaming media player, while maintaining a current status of an audio component of the streaming media file.

9. The non-transitory machine-readable storage medium of claim 8, wherein the first tab of the user interface is not visible to the user when the first tab is in the background of the user interface, behind one or more other tabs including the second tab.

10. The non-transitory machine-readable storage medium of claim 8, the operations further comprising:

halting a transmission of the video component of the streaming media file to the user device; and

continuing to transmit an audio component of the streaming media file to the user device.

11. The non-transitory machine-readable storage medium of claim 8, the operations further comprising:

if the first tab of user interface is currently visible to the user, determining if the video component is currently decreased from a default setting.

12. The non-transitory machine-readable storage medium of claim 11, the operations further comprising:

if the video component is currently decreased from the default setting, increasing the quality of the video component to the default setting; and

if the video component is not currently decreased from the default setting, maintaining a current quality of the video component.

13. The non-transitory machine-readable storage medium of claim 11, wherein the tab of the user interface is visible to the user if the first tab is in the foreground of the user interface.

14. The non-transitory machine-readable storage medium of claim 8, wherein receiving the data indicating the visibility status of the first tab comprises sending a request for the visibility status of the first tab using a page visibility application programming interface of the user interface.

15. A system comprising:

a processing device;

a memory coupled to the processing device; and

a video quality module, executable by the processing device from the memory, to;

provide, from a media streaming server, a streaming media file to a streaming media player in a first tab of a plurality of tabs of a user interface running on a user device, wherein a second tab of the plurality of tabs comprises content not including the streaming media player;

receive, at the media streaming server, data from the user device indicating a visibility status of the first tab of the plurality of tabs in the user interface running on the user device;

determine, based on the data indicating the visibility status of the first tab, whether the first tab of the user interface is currently visible to a user of the user device, wherein the first tab is not visible to the user when the second tab of the plurality of tabs is selected; and

if the first tab of the user interface is not currently visible to the user, decrease, by the media streaming server, a quality of a video component of a streaming media file being transmitted to the user device and playing in the streaming media player, while maintaining a current status of an audio component of the streaming media file.

16. The system of claim 15, wherein the first tab of the user interface is not visible to the user when the first tab is in the background of the user interface, behind one or more other tabs including the second tab.

17. The system of claim 15, the video quality module further to:

halt a transmission of the video component of the streaming media file to the user device; and

continue to transmit an audio component of the streaming media file to the user device.

18. The system of claim 15, the video quality module further to:

if the first tab of user interface is currently visible to the user, determine if the video component is currently decreased from a default setting.

19. The system of claim 18, the video quality module further to:

if the video component is currently decreased from the default setting, increase the quality of the video component to the default setting; and

if the video component is not currently decreased from the default setting, maintain a current quality of the video component.

20. The system of claim 18, wherein the tab of the user interface is visible to the user if the first tab is in the foreground of the user interface.

21. The system of claim 15, wherein receiving the data indicating the visibility status of the first tab comprises sending a request for the visibility status of the first tab using a page visibility application programming interface of the user interface.
