Patent number: 12075124Abstract: Methods and systems are provided for streaming a media asset with an adaptive bitrate transcoder. A server receives, from a client device, a first request for a first portion of the plurality of portions to be transcoded at a first bitrate. The server then starts to transcode the plurality of portions at the requested first bitrate to generate a plurality of corresponding transcoded portions. The server updates a header of a transcoded portion to include: 1) a transcode latency value; and 2) a count value indicating a number of available pre-transcoded portions of the media asset at the time the first request was received. The server then transmits the transcoded portion to the client. The client device then determines a second bitrate based on the transcode latency value included in the header of the transcoded portion corresponding to the first portion.Type: GrantFiled: October 25, 2022Date of Patent: August 27, 2024Assignee: Rovi Guides, Inc.Inventors: Steven Mayhew, Maciej Dobrzynski, Jonathan Oliver

Patent number: 12014452Abstract: The present disclosure describes systems, methods, and non-transitory computer readable media for detecting user interactions to edit a digital image from a client device and modify the digital image for the client device by using a web-based intermediary that modifies a latent vector of the digital image and an image modification neural network to generate a modified digital image from the modified latent vector. In response to user interaction to modify a digital image, for instance, the disclosed systems modify a latent vector extracted from the digital image to reflect the requested modification. The disclosed systems further use a latent vector stream renderer (as an intermediary device) to generate an image delta that indicates a difference between the digital image and the modified digital image. The disclosed systems then provide the image delta as part of a digital stream to a client device to quickly render the modified digital image.Type: GrantFiled: August 14, 2023Date of Patent: June 18, 2024Assignee: Adobe Inc.Inventors: Akhilesh Kumar, Baldo Faieta, Piotr Walczyszyn, Ratheesh Kalarot, Archie Bagnall, Shabnam Ghadar, Wei-An Lin, Cameron Smith, Christian Cantrell, Patrick Hebron, Wilson Chan, Jingwan Lu, Holger Winnemoeller, Sven Olsen

Patent number: 8380249Abstract: The present invention proposes a transmission method for transmitting data in a telecommunication network (NW), said telecommunication network comprising at least one access network (RAN) adapted to transmit data to/from at least one terminal device (MS) and a core network (CN, MSC, GW/TC), which are connected to each other via a first interface (Iu), wherein said data are exchanged via said first interface (Iu) using a real-time transfer protocol (RTP). Preferably, said real-time transfer protocol complies with ITU-T H.225 and ITU-T H.323 Recommendations. Consequently, transmission resources available on said first interface can be effectively and economically used, since the RTP protocol conforming to ITU-T H.323 Recommendation is adapted to handle discontinuous transmission.Type: GrantFiled: September 6, 2001Date of Patent: February 19, 2013Assignee: Nokia Networks OyInventor: Jyri Suvanen
