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: 11039102Abstract: Various techniques for providing video feed redundancy are described herein. Instructions may be provided for switching input to an output video feed between two or more redundant input video feeds. In some examples, the redundant input video feeds may not be duplicates, may not be frame synchronized, may not be transmitted from the same location, may not be transmitted using the same network types or transmission protocols, and/or may not be initiated at the same time. In some examples, the instructions for video feed redundancy may be associated with respective authorization keys for the redundant input video feeds.Type: GrantFiled: December 12, 2017Date of Patent: June 15, 2021Assignee: Twitch Interactive, Inc.Inventors: Ivan Marcin, Jonas Bengtson, Tarek Amara, Shawn Hsu, Abhinav Kapoor, Jorge Arturo Villatoro, Eran Ambar

Patent number: 10397291Abstract: First streaming video content may be received from a provider. The provider may issue a request to replace part of the first streaming video content with replacement content, such as advertisements. Second streaming video content may be selected as a replacement for a first video player, while third streaming video content may be selected as a replacement for a second video player. Instructions may be sent to the first and the second video player to play a first portion of the first streaming video content, followed by their respective selected replacement content, followed by a third portion of the first streaming video content, with the respective selected replacement content replacing a second portion of the first streaming video content. Replacement of the second portion of the first streaming video content may sometimes introduce latency, which may be reduced using various techniques.Type: GrantFiled: March 29, 2017Date of Patent: August 27, 2019Assignee: Twitch Interactive, Inc.Inventors: Cyrus Hall, Daniel Lin, Maciej Laszcz, Luke Curley, Matthew Louis Szatmary, Abhinav Kapoor, Daniel Arthur McClain, Diana Lu, Scott Wang, Spencer Nelson, Phillip Conover, Scott Rabin, Jorge Arturo Villatoro

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: 9788077Abstract: Techniques for improved rendition switching in association with adaptive bitrate streaming are described herein. The disclosed techniques may allow switching between segments at P-frames in addition to IDR-frames. By allowing switching at P-frames, the disclosed techniques may improve efficiency by, for example, reducing end-to-end latency without causing an undesirable decrease in image quality and image fidelity. In some examples, switching to a lower image quality rendition (e.g., lower bitrate, lower resolution, etc.) may be accomplished using P-frame switching, IDR-frame switching or both. Also, in some examples, switching to a higher image quality rendition (e.g., higher bitrate, higher resolution, etc.) may be accomplished using only IDR-frame switching.Type: GrantFiled: March 18, 2016Date of Patent: October 10, 2017Assignee: Amazon Technologies, Inc.Inventors: Yueshi Shen, Jorge Arturo Villatoro, Matthew Louis Szatmary
