Patent number: 11812103Abstract: 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.Type: GrantFiled: October 13, 2022Date of Patent: November 7, 2023Assignee: ROKU, INC.Inventors: Chung Won Seo, Seunghyeong Lee

Patent number: 11539987Abstract: One high-level aspect of a content-modification system and related methods may involve facilitating content modification by a content-presentation device of received broadcast content in a controlled manner, while under circumstances in which some events that can impact timing may be unpredictable. In particular, certain operations by a content-presentation device may involve matching received content with specific expected content as determined by one or another component of the content-modification system, in order to confirm proper conditions are met for the content-presentation device to proceed with, or continue, content-modification operations. It can happen the matching procedure becomes subject or susceptible to timing irregularities, or jitter. In some instances, jitter may impact the ability to derive the benefits of content modification. Accordingly, example embodiments herein are directed to systems and method for compensation and/or mitigating the effects of jitter.Type: GrantFiled: February 19, 2021Date of Patent: December 27, 2022Assignee: ROKU, INC.Inventors: Shashank Merchant, Bruce William Randall, Brian Johnson, Chungwon Seo, Seunghyeong Lee, Paul Jeffrey Holmquist

Patent number: 11317143Abstract: 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.Type: GrantFiled: November 7, 2018Date of Patent: April 26, 2022Assignee: Roku, Inc.Inventors: Chung Won Seo, Seunghyeong Lee

Patent number: 11245870Abstract: In one aspect, a method for use in connection with a content-presentation device including a first input buffer, a second input buffer, and an output buffer, wherein the content-presentation device is configured such that content from either the first input buffer or the second input buffer can be communicated to the output buffer, includes: (i) receiving, from the content-presentation device, an identifier associated with the content-presentation device; (ii) using mapping data to map the received identifier to a baseline input-to-output delay, which represents a time-period between when content is input into the first input buffer and output by the output buffer; and (iii) transmitting, to the content-presentation device, the mapped baseline input-to-output delay to the content-presentation device to facilitate the content-presentation device (a) determining an input-buffer switching delay, and (b) using the determined input-buffer switching delay to facilitate performing a content-modification operation.Type: GrantFiled: June 18, 2020Date of Patent: February 8, 2022Assignee: Roku, Inc.Inventors: Chungwon Seo, Seunghyeong Lee, Shashank Merchant
