发明名称 Apparatus, systems and methods for user controlled synchronization of presented video and audio streams
摘要 Systems and methods are operable to correct synchronization between a video stream and an audio stream presented to a user. An exemplary embodiment receives a synchronization correction instruction, wherein the synchronization correction is configured to be initiated by the user; and incrementally adjusts one of the video stream and the audio stream by a synchronization correction, wherein the synchronization correction advances or retards presentation of at least one of the video stream and the audio stream by a predefined duration.

主权项 1. A method comprising: storing synchronization correction information in a memory of a media device wherein the synchronization correction information specifies a predefined synchronization correction duration; receiving a media content stream at the media device, the media content stream comprising a video stream and an audio stream; communicating the video stream to a display for presentation to a user of the media device; communicating the audio stream to one or more speakers for presentation to the user of the media device, wherein presentation of the audio stream is unsynchronized with presentation of the video stream by a first duration, and wherein the first duration of unsynchronized presentation corresponds to an amount of unsynchronized presentation between the audio stream and the video stream that is perceivable by the user; receiving a user initiated synchronization correction instruction; retrieving the synchronization correction information from the memory of the media device in response to receiving the user initiated synchronization correction instruction, wherein the user initiated synchronization correction instruction is configured to reduce the first duration of unsynchronized presentation to a second duration of unsynchronized presentation, wherein a difference between the first duration of unsynchronized presentation and the second duration of unsynchronized presentation equals the predefined synchronization correction duration so that the second duration of unsynchronized presentation is less perceivable to the user; and incrementally adjusting the video stream by a synchronization correction that equals the predefined synchronization correction duration, wherein the synchronization correction advances presentation of the video stream by the predefined synchronization correction duration.
