Patent number: 11936765Abstract: Some embodiments include an apparatus, method, and computer program product for high precision device synchronization of electronic devices in a shared medium. Some embodiments include a first electronic device that utilizes a combination of synchronization techniques to synchronize with a second electronic device. The first electronic device receives a first signal from the second electronic device that includes network-based synchronization data and marker data, and performs network-based synchronization with the second electronic device at a first synchronization accuracy. The first electronic device receives a second signal, and uses the marker data and phase lock synchronization to detect a frequency change of the second signal received, as well as to determine a corresponding time marker. The first electronic device updates a clock of the first electronic device based at least on the corresponding time marker, the network-based synchronization data, and the marker data.Type: GrantFiled: June 24, 2022Date of Patent: March 19, 2024Assignee: Roku, Inc.Inventors: Jan Neerbek, Bjorn Reese, Brian Moller

Publication number: 20230283830Abstract: The invention provides a method for providing a synchronization in a computer network for synchronized playback of audio an/or video by a plurality of separate devices. Each separate device generates a virtual clock in response to a timing of the audio codec of a received audio stream. Especially, segmented time is used as reference time. Either the virtual clock is generated directly in response to the tick counter of the audio codec, or by a periodic measurement of the timing of the audio codec extrapolated by a monotonic clock. A sample rate converter may be used to slightly adjust the frequency of the virtual clock.Type: ApplicationFiled: March 10, 2023Publication date: September 7, 2023Inventors: PAUL FLEISCHER, Brian Thoft Moth Moller, Bjorn Reese

Patent number: 10614856Abstract: Disclosed herein are device, method, and computer program product embodiments for synchronizing playback of audio and/or video content. An embodiment operates by a first device in concert with a second device to collectively select a preferred synchronization mechanism over a third device's default synchronization mechanism such that the third device serves as a session leader. The preferred synchronization mechanism's selection is in accordance with a predetermined prioritized synchronization list comprising the default and preferred synchronization-mechanisms and a virtual clock generated from a timing of an audio codec used for streaming the audio and/or video content. The session leader's default synchronization mechanism has a lower level of priority than the first and second devices' preferred synchronization mechanism. The preferred synchronization mechanism provides a more precise level of synchronization for playback of the audio and/or video content than the default synchronization mechanism.Type: GrantFiled: January 27, 2016Date of Patent: April 7, 2020Assignee: Roku, Inc.Inventors: Brian Thoft Moth Møller, Paul Fleischer, Bjørn Reese

Patent number: 10231008Abstract: The invention provides a protocol and a method for a plurality of separate devices to stream audio and/or video in a synchronized manner in a computer network. One device is session leader and controls synchronization of the streaming of the other devices. If the session leader device is switched off, or becomes otherwise unavailable, local election algorithms on the other devices serve to automatically elect a new session leader to synchronize to in an autonomous manner, e.g. based on a random number election based algorithm. In this manner, a self-organizing synchronization network is provided.Type: GrantFiled: January 27, 2016Date of Patent: March 12, 2019Assignee: ROKU, INC.Inventors: Brian Thoft Moth Møller, Paul Fleischer, Bjørn Reese

Publication number: 20180012632Abstract: A method is provided for synchronizing playback of audio an/or video by a plurality of separate devices in a computer network, e.g. in a wi-fi network. Each separate device is programmed to select a synchronization mechanism in accordance with a predetermined prioritized list of at least two different synchronization mechanisms, and to use the selected synchronization mechanism for synchronizing audio and/or video playback. E.g. use of a clock based on the audio codec clock can be set to a higher priority than use of the system clock, which provides a poorer precision. A session leader serves to provide the synchronization to other separate devices in a session, however a group of two or more separate devices within the session may agree on selecting a synchronization mechanism providing a higher precision than the one provided by the session leader. E.g. to allow high precision timing between separate left and right loudspeakers in a stereo setup.Type: ApplicationFiled: January 27, 2016Publication date: January 11, 2018Applicant: Dynastrom ApSInventors: Brian Thoft Moth Møller, Paul Fleischer, Bjørn Reese
