US Patent 10218760 Dynamic summary generation for real-time switchable videos

In viewing a media presentation having multiple streams or tracks running in parallel and synchronized to a common playback timeline, a user experiencing one of the streams will miss interesting events and other content occurring in other streams. Accordingly, upon receiving an instruction to switch from a first stream to a second stream, a summary of the second stream is dynamically generated based on content that the user missed while watching the first stream. The summary is presented to the user prior to transitioning to presentation of the second stream.
