Patent number: 9872062Abstract: Synchronization of audio and video data can be enforced by embedding audio within video frame data. In a network environment in which audio and video data are generated on a source computing device and then transferred over the network to a destination computing device for output, the source computing device can be configured to encode the video data into an encoded video stream. As part of this encoding, the source computing device can also embed audio in the encoded video stream in a manner that associates the audio with corresponding video frames. The encoded video stream with the embedded audio can then be transferred over the network. The destination computing device can be configured to parse the encoded video stream to remove the audio and route it to an audio buffer and then route the encoded video stream to a GPU.Type: GrantFiled: February 22, 2017Date of Patent: January 16, 2018Assignee: WYSE TECHNOLOGY L.L.C.Inventors: Oleg Rombakh, Richard Goldberg

Patent number: 8819268Abstract: The disclosed technology includes systems and methods providing event- or condition-based notifications of device mirroring responsive to one or more of changes in the physical or internal environments of a computing device, for example a mobile computing device. Moreover, some implementations may include stopping or suspending device mirroring responsive to the same. A change in the physical environment of a computing device may be determined from a change in a signal received at the device, for example a network connection signal, IR signal, or ambient light or noise level. A change in physical environment may also be determined based on a change in location or orientation of the computing device. A change in the internal environment of the computing device may include a change in the active application at the device, or a change in focus to a new application.Type: GrantFiled: June 19, 2013Date of Patent: August 26, 2014Assignee: Google Inc.Inventor: Fred Sauer
