Patent number: 10992999Abstract: Techniques are disclosed for seamless media content switching during fixed-duration breaks. A user can request that a first media content item played by a client device during a fixed-length break be skipped. A server can determine an amount of time remaining in the break, determine an updated playlist of one or more media content items that together at least partially but not completely consume the entire amount of remaining time, and provide the updated playlist to the client device. The client device can determine a delay duration amount of time that it will continue playing the first media content item before skipping to a media content item from the updated playlist. This delay duration is determined such that the entire break can be filled with media content without any dead air or clipped media content.Type: GrantFiled: June 5, 2019Date of Patent: April 27, 2021Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Stefan Paul Redmond, Mario Colina

Patent number: 10616623Abstract: The “swarming” behavior of multimedia content distribution network subscribers—numerous, near-simultaneous requests for the same content by different users—is predicted, based on analysis of past viewing habits. Users are grouped based on correlations in the multimedia content requested and the time at which it is requested. When a set of users of a group requests particular multimedia content, that content is autonomously distributed, via a shared distribution channel, to the terminal equipment of all users in the group, where it is buffered. As other users in the group request the same multimedia content, an initial portion is distributed to each requesting user via an individual channel. As the rendered content catches up to the buffered content, the terminal equipment switches from the content delivered via the individual distribution channel to the buffered content. The individual distribution is then terminated, and the individual distribution channel released.Type: GrantFiled: January 9, 2017Date of Patent: April 7, 2020Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventor: Stefan Paul Redmond

Patent number: 10313162Abstract: The embodiments described herein provide communication devices and methods that can facilitate communication between galvanically isolated systems. Specifically, the embodiments facilitate communication to a galvanically isolated system that is shut down without requiring that this shutdown system consume its own power while it is shutdown. To facilitate this, the communication devices and methods provide a wake-up device on the side of the shutdown system and facilitate the transfer of power across the galvanic isolation to the wake-up device when communication to the shutdown system is needed. With the wake-up device powered using power that was transferred across the galvanic isolation, the wake-up device can perform the actions needed to wake up the shutdown system, and can thus facilitate communication between the galvanically isolated systems. Thus, communication between galvanically isolated systems is facilitated without requiring that the shutdown system consume its own power during shutdown periods.Type: GrantFiled: April 27, 2018Date of Patent: June 4, 2019Assignee: NXP B.V.Inventors: Stefan Paul Van Den Hoek, Lucas Pieter Lodewijk Van Dijk, Cecilius Gerardus Kwakernaat
