WIRELESS DISPLAY SYNCHRONIZATION FOR MOBILE DEVICES USING BUFFER LOCKING

摘要

One embodiment of the present invention includes techniques for synchronizing displays of a plurality of mobile devices over a wireless network. A processing unit renders an image frame related to a software application into an application image buffer associated with a first mobile device and causes a second mobile device to render a second image frame into a second application image buffer of the second mobile device. The processing unit receives an acknowledgement over a wireless network indicating that the second mobile device has completed rendering the second image frame. The processing unit displays contents of the application image buffer on a first display device associated with the first mobile device and transmits a signal to the second mobile device over a wireless network that causes the second mobile device to display contents of the second application image buffer on a second display device associated with the second mobile device.

主权项

1. A method for synchronizing displays of a plurality of mobile devices over a wireless network, the method comprising:
rendering a first image frame related to a software application into a first application image buffer associated with a first mobile device; causing a second mobile device to render a second image frame substantially similar to the first image frame into a second application image buffer associated with the second mobile device; receiving an acknowledgement over a wireless network indicating that the second mobile device has completed rendering the second image frame into the second application image buffer; displaying contents of the first application image buffer on a first display device associated with the first mobile device; and transmitting a signal to the second mobile device over a wireless network that causes the second mobile device to display contents of the second application image buffer on a second display device associated with the second mobile device.
