Publication number: 20200221152Abstract: 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: March 16, 2020Publication date: July 9, 2020Applicant: DIVX, LLCInventors: William David Amidei, Abhishek Shivadas, Kevin Dean-Yong Wu

Publication number: 20190044995Abstract: 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: August 10, 2018Publication date: February 7, 2019Applicant: DIVX, LLCInventors: William David Amidei, Jason Braness, Cristina Dobrin
