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

Publication number: 20100283693Abstract: A wireless terminal antenna is disclosed. The antenna includes a pull rod, a pull rod pedestal located at the base of the pull rod, and a spiral coil. One end of the spiral coil is electrically connected with the pull rod pedestal. The pull rod is axially retractable along the pull rod pedestal until it is retracted into the space enclosed by the spiral coil. At idle time, the pull rod is nested inside the spiral coil so that it is short and portable. When receiving signals normally, the pull rod can be pulled out. The antenna is miniaturized, portable, and provides good performance.Type: ApplicationFiled: June 28, 2010Publication date: November 11, 2010Applicant: HUAWEI DEVICE CO., LTD.Inventors: Yanping XIE, Shaoqing CHEN, Ping LEI, Yongling BAN, Shuhui SUN, Yao LAN
