Publication number: 20230388571Abstract: Systems and methods for encoding a plurality of alternative streams of video content using multiple encoders in accordance with embodiments of the invention are disclosed. An encoding system includes multiple encoders. Each of the encoders receives a source stream of video content that is divided into portions. Each of the encoders generates portions of the plurality of alternative streams from the portions of the source stream. The portions of the alternative streams generated by a particular encoder are stored in a container for the particular encoder. Each encoder also generates index information for the portion of the alternative stream generated by the encoder that is stored in a manifest for the encoder.Type: ApplicationFiled: August 14, 2023Publication date: November 30, 2023Applicant: DIVX, LLCInventors: William David Amidei, Abhishek Shivadas, Kevin Dean-Yong Wu

Publication number: 20230336612Abstract: Systems and methods for quick start-up of playback in accordance with embodiments of the invention are disclosed. Media content may be encoded in a plurality of alternative streams and a quick start-up stream. The quick start-up stream may include media content that is encoded at a lower quality that the alternative streams and may be encrypted with a different, less secure encryption process than that of the alternative streams. During a start-up of playback, the playback device streams the media content from a quick start-up stream until a metric, such as a decryption key for the alternative streams is met. The device then streams the media content from the alternative streams in response to the metric being met.Type: ApplicationFiled: December 19, 2022Publication date: October 19, 2023Applicant: DIVX, LLCInventors: William David Amidei, Jason Braness, Cristina Dobrin

Patent number: RE48761Abstract: A method includes encoding video at a first bitrate to produce first encoded sections, and at a second bitrate that is less than the first bitrate to produce second encoded sections. The method further includes measuring levels of objective quality, indicative of perceptual quality, of the first and second encoded sections. The method includes determining, based on the measured objective quality levels, replaceable sections among the first encoded sections, and replacement sections among the second encoded sections, each of the replacement sections to replace a corresponding one of the replaceable sections. the method includes streaming the first encoded sections except for the replaceable sections, and the replacement sections instead of their corresponding replaceable sections.Type: GrantFiled: April 11, 2018Date of Patent: September 28, 2021Assignee: DIVX, LLCInventors: Abhishek Shivadas, William David Amidei
