Publication number: 20230412796Abstract: Systems and methods for hybrid video compression. A method includes receiving an encoded video including at least two compressed frames corresponding to at least two anchor frames and a compressed subset of at least one intermediate frame between the at least two anchor frames, generating, by inputting the at least two anchor frames into a deep machine learning model, a synthesized image frame corresponding to the at least one intermediate frame between the at least two anchor frames, reconstructing at least one hybrid image frame by combining the compressed subset of the at least one intermediate frame with the synthesized image frame, and outputting a video including the at least two anchor frames and the at least one hybrid image frame. Thus, DCT-based video compression techniques can leverage machine learning-based video interpolation techniques to provide encoded video streams with a reduced bitrate and thus reduced bandwidth while maintaining image quality.Type: ApplicationFiled: November 8, 2021Publication date: December 21, 2023Inventors: Feng Liu, Wu-Chi Feng

Patent number: 11129072Abstract: Router advertisements may be used to configure multi-homed Protocol Data Unit (PDU) sessions. A first router advertisement message from a first PDU session anchor and a second router advertisement message from a second PDU session anchor may be decoded. A user equipment (UE) may identify, based on the first and second router advertisement messages, a first preference value associated with destination routes of the first network and a second preference value associated with destination routes of the second data network. The UE may determine a destination data network for a signal by comparing a destination route of the signal to destination routes associated with whichever data network has a greater preference value. The UE may prepare the signal with a prefix based on the destination data network.Type: GrantFiled: February 26, 2018Date of Patent: September 21, 2021Assignee: APPLE INC.Inventors: Alexandre Saso Stojanovski, Danny Moses, Wu-Chi Feng

Patent number: 9124673Abstract: Technology for reducing delay in data streaming at a wireless device while improving re-buffering and video quality is disclosed. A missing data segment can be detected based on an out-of-order data segment being received in a plurality of data segments from a network element in a wireless network. A fake acknowledgement (ACK) can be sent to the network element in the wireless network, based on the context information, acknowledging that the missing data segment was received at the wireless device. The out-of-order data segment without the missing data segment can be provided for display at the wireless device.Type: GrantFiled: September 30, 2013Date of Patent: September 1, 2015Assignee: INTEL IP CORPORATIONInventors: Vallabhajosyula S.

Publication number: 20150089382Abstract: Embodiments described herein relate generally to the migration of a static object, such as an electronic document, across separate computer systems while retaining context data associated with the static object. In one embodiment, a source computer system is adapted to package a static object and associated context information and transmit the package over a network to a target computer system. The target computer system may present the static object in an application with the associated context information to substantially approximate presentation of the same at the source computer system. Other embodiments may be described and claimed.Type: ApplicationFiled: March 26, 2014Publication date: March 26, 2015Inventors: Wu-Chi Feng, Muthaiah Venkatachalam, Meghashree Kedalagudde

Publication number: 20100232504Abstract: Region-of-interest cropping of high-resolution video is supported video compression and extraction methods. The compression method divides each frame into virtual tiles, each containing a rectangular array of macroblocks. Intra-frame compression uses constrained motion estimation to ensure that no macroblock references data beyond the edge of a tile. Extra slice headers are included on the left side of every macroblock row in the tiles to permit access to macroblocks on the left edge of each tile during extraction. The compression method may also include breaking skipped macroblock runs into multiple smaller skipped macroblock runs. The extraction method removes slices from virtual tiles that intersect the region-of-interest to produce cropped frames. The cropped digital video stream and the compressed digital video stream have the same video sequence header information.Type: ApplicationFiled: March 11, 2010Publication date: September 16, 2010Inventor: Wu-chi Feng
