Dynamic Playout of Transition Frames while Transitioning Between Playout of Media Streams
Publication/Patent Number: US2020059691A1 Publication Date: 2020-02-20 Application Number: 16/183,185 Filing Date: 2018-11-07 Inventor: Seo, Chung Won   Lee, Seunghyeong   Assignee: Gracenote, Inc.   IPC: H04N21/44 Abstract: When a device is playing out a first media stream, the device determines a target time for beginning playout of a second media stream in place of the first media stream. The device then starts a stream-transition process that is expected to take anywhere from a minimum expected transition duration to a maximum expected transition duration, and the device starts the transition process in advance of the determined target time by the maximum expected transition duration, to help ensure timely starting of playout of the second media stream. Further, for an uncertainty period that extends from the minimum expected transition duration after the starting to the maximum expected transition duration after the starting, the device generates and plays a sequence of transition frames to help mask transition from the first media stream to the second media stream.

Dynamic Reduction in Playout of Replacement Content to Help Align End of Replacement Content with End of Replaced Content
Publication/Patent Number: US2020059692A1 Publication Date: 2020-02-20 Application Number: 16/183,266 Filing Date: 2018-11-07 Inventor: Seo, Chung Won   Lee, Seunghyeong   Assignee: Gracenote, Inc.   IPC: H04N21/44 Abstract: When a device is playing out a media stream, the device determines a target time at which the device is to start playing out replacement content in place of a portion of the media stream. However, the device then detects that a starting time when the device starts playout of the replacement content is delayed from the target time by a delay period of duration P. In response, the device then reduces its playout of the replacement content by duration P, to help playout of the replacement content end at a desired time. For instance, the device could seek forward in playout of the replacement content by duration P and/or could remove one or more other portions of the replacement content to total a reduction of duration P.
