Publication number: 20240137585Abstract: In some embodiments, a method sends a set of first requests for a set of first segments of a video in a playback session. A first protocol from a plurality of protocols is specified in at least one of the set of first requests. The set of first segments is received. The method determines whether to switch from using the first protocol to a second protocol in the playback session based on receiving the set of first segments. When switching to the second protocol, the method sends a second request in the playback session, wherein the second request indicates the second protocol is to be used to send a second segment of the video.Type: ApplicationFiled: January 2, 2024Publication date: April 25, 2024Applicant: HULU, LLCInventors: Tongyu Dai, Lan Xie, Wenhao Zhang, Deliang Fu, Chao Li, Qiang She, Yuting Gui, Yicheng Liu, Yanping Zhou, Xizhi Xu
