Patent number: 11589088Abstract: Media content is encoded based on network quality of service parameters. For instance, quality of service parameters for a network between a media server and a media client are determined by a system. The system selects an encoder based on a list of decoders available at the media client and the quality of service parameters, and encodes at least a portion of the media via the encoder. The system can further determine settings for the encoder based on a media type, and encode the media via the encoder according to the settings. The system can detect when the media client moves to a new network, detect new quality of service parameters, and select a new encoder based on the list of decoders available at the media client, the media type, and the new quality of service parameters.Type: GrantFiled: October 1, 2020Date of Patent: February 21, 2023Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Todd Andrew Fryer, David Irvin, Nick Nicas

Publication number: 20230028218Abstract: Aspects of the subject disclosure may include, for example, a method in which a processing system of a media server determines a number of media content playout periods in a media program to be presented at a client device, obtains a media content item for presentation during a playout period, and transmits the media content item for storage in a client device cache prior to presentation of the media program. The method also includes transmitting to the client device a time stamp associated with the transmitting of the media content item, and transmitting an instruction to the client device to perform buffering of streaming media during the playout period. The client device also transmits a first message indicating that the transmitting of the media content item has been performed, and a second message indicating that the presenting of the media content item has been completed. Other embodiments are disclosed.Type: ApplicationFiled: October 4, 2022Publication date: January 26, 2023Applicant: AT&T Intellectual Property I, L.P.Inventors: Nicholas Nicas, Todd Fryer, David Irvin
