Abstract

The present disclosure generally relates to synchronization between multiple displays for audio and/or visual content. Video, movie, television, live broadcast, streaming or online content typically include visual content and corresponding audio content synchronized to the visual content, i.e., a particular audio frame is set to be play backed at the same time a particular video frame is displayed. The present disclosure provides for delaying the presentation of visual content with respect to one or more displays in order to synchronize the presentation of the visual content on the displays.

Background

TECHNICAL FIELD(1) The technology described herein relates generally to systems and methods for display and editing of content, such as audio/visual content.BACKGROUND(2) Traditional systems for production and post-production engineering or editing of media content such as video, movies, or television often use multiple monitors or displays that display the content, allowing multiple people (often with different focuses) to simultaneously edit content. For instance, a media stream containing both audio content and visual content is played from a workstation to two or more displays. For instance, one display may be associated with a workstation and monitored by a production engineer editing or playing back media content and another display may be monitored by a director, producer or other person reviewing and directing the work of the production engineer, and/or focusing on editing of other aspects or characteristics of the content.(3) Different displays may exhibit varying display latencies due to various hardware and software characteristics causing a lag or time delta between content (either between the two screens) and/or loss of synchronization between audio content and visual content. These varied content playback issues can make the editing environment difficult for engineers. For example, the audio/visual lag can cause an actor's mouth to move visually without the corresponding audio being played. Notably, even displays of the same manufacturer/model can have different

Claims

1. A method for synchronizing content playback over multiple displays comprising: displaying visual content for presentation on a first display of the multiple displays; receiving a user input selecting the visual content; receiving a delay amount to delay presentation of the visual content on a second display of the multiple displays; and displaying, by a processing element, a delayed visual content for presentation on the second display, wherein the delayed visual content comprises the visual content delayed by the delay amount such that presentation of the visual content on the first display is synchronized with the presentation of the delayed visual content on the second display. 18. A system for synchronizing content comprising: a workstation, the workstation including: a processing element; a memory component in communication with the processing element and storing visual content retrievable by the processing element; a video interface operable to transmit the visual content to a first display and a second display, wherein the processing element is operable to transmit, via the video interface, the visual content to one of the first or second displays and to delay transmission of the visual content by a delay amount to the other of the first or second displays. 20. A non-transitory computer storage medium including instructions that when executed by at least one processor of a computing system cause the computing system to perform a method comprising: displaying visual content for presentation on a first display; receiving a user input selecting the visual content; receiving a delay amount to delay presentation of the visual content on a second display; and displaying a delayed visual content for presentation on the second display comprising the visual content delayed by the delay amount, wherein presentation of the visual content on the first display is synchronized with the presentation of the delayed visual content on the second display.
