Patent number: 11425178Abstract: Techniques for low latency streaming, for example in a broadcasting environment, are described herein. In some examples, a playlist may include both currently encoded segments, which are segments that are fully encoded at or before playlist generation, and also future encoded segments, which are segments that have not yet been fully encoded at playlist generation. In some cases, the inclusion of future encoded segments in a playlist may result in a player requesting a segment that has not yet been fully encoded at the time that the request is received by the server. In some examples, even though the segment is not yet fully encoded, the server may nevertheless save and process the request, for example by transmitting encoded portions of the requested segment as those portions are made available by the encoder.Type: GrantFiled: June 30, 2020Date of Patent: August 23, 2022Assignee: Twitch Interactive, Inc.Inventors: Yueshi Shen, Martin Hess, Shawn Hsu, Eran Ambar, Abhinav Kapoor, Jorge Arturo Villatoro, Spencer Nelson, Jeffrey Garneau, Cyrus Hall, Jyotindra Vasudeo, Andrew Francis, Yuechuan Li, Chih-Chiang Lu

Patent number: 11146834Abstract: Techniques for low latency streaming, for example in a broadcasting environment, are described herein. In some examples, one or more individual renditions may be encoded into multiple rendition versions associated with different respective latencies. Also, in some examples, one or more individual renditions may be encoded into multiple rendition versions having different respective amounts of forward error correction (FEC), for example by an edge node of a video streaming service. Also, in some examples, video may be broadcast using a protocol that does not require retransmission of lost packets, such as Web Real-Time Communication (WebRTC), which is commonly used for point-to-point transmissions. Also, in some examples, one or more servers may receive quality of service feedback information from each player to which video content is transmitted. The one or more servers may use this feedback information to select and switch between appropriate renditions and rendition versions for each player.Type: GrantFiled: September 28, 2017Date of Patent: October 12, 2021Assignee: Twitch Interactive, Inc.Inventors: Yueshi Shen, Martin Hess, Shawn Hsu, Eran Ambar, Abhinav Kapoor, Jorge Arturo Villatoro, Spencer Nelson, Jeffrey Garneau, Cyrus Hall, Jyotindra Vasudeo, Andrew Francis, Yuechuan Li, Chih-Chiang Lu

Patent number: 10484730Abstract: Techniques for estimation of bandwidth for transfer of video content in chunked transfer mode are described herein. A number of chunk samples may be collected during video content transmission. For each chunk sample, its respective delivery speed may be compared to its respective encoding bitrate. If the delivery speed is greater than or equal to the encoding bitrate, then the chunk sample may be included in a primary set of chunk samples. The primary set of chunk samples may be clustered into a lower speed cluster and a higher speed cluster. A representative speed, such as an average or weighted average speed, of the delivery speeds of the chunk samples in the lower speed cluster may be determined, and the bandwidth may be estimated based on the representative speed.Type: GrantFiled: January 24, 2018Date of Patent: November 19, 2019Assignee: Twitch Interactive, Inc.Inventors: Yuechuan Li, Yueshi Shen, Graham Keefe Tremper, Abhinav Kapoor, Matthew Szatmary, Nikhil Purushe, Eran Ambar

Patent number: 10116989Abstract: The techniques described herein may, for example, allow a quantity of buffered video frames to be reduced, for example for use in adaptive bitrate (ABR) streaming and other streaming transmissions. The quantity of buffered video frames may be reduced by dropping certain selected buffered frames from a resulting video output that is displayed to the viewer. This may reduce end-to-end latency without requiring a change in frame rate or fast forwarding of the video output, which may sometimes not be available or permitted by a resulting video player. These buffer reduction techniques may sometimes be employed upon a determination that transmission conditions have stabilized and that holding large quantities of buffered video may be unnecessary. In some examples, the disclosed techniques may be particularly advantageous for live streaming scenarios, in which end-to-end latency may be particularly problematic for the viewer.Type: GrantFiled: September 12, 2016Date of Patent: October 30, 2018Assignee: Twitch Interactive, Inc.Inventors: Yueshi Shen, Ivan Marcin, Josh Tabak, Abhinav Kapoor, Jorge Arturo Villatoro, Jeff Li

Patent number: 8321905Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for fast switching of media streams, are described. The methods and systems described in this specification enable switching media streams as quickly as possible without playback interruption by not having to playback the content of the full buffer prior to the switch to the new stream. The fast switching disclosed in this specification is based on configuring a media player operated at a client computer to specify a switching time offset that corresponds to buffered content. In addition, the disclosed methods and systems enable a media streaming server computer, that is streaming a first media stream to the client computer, to select a key frame of a second media stream that is at or near a switching time offset specified by the client computer, and to immediately begin transmission of the second media stream.Type: GrantFiled: October 2, 2009Date of Patent: November 27, 2012Assignee: Adobe Systems IncorporatedInventors: Kevin Streeter, Stephen Cheng, Abhinav Kapoor
