Patent number: 10178428Abstract: Chunks (12, 14) of encoded video data of a streamed video bitstream (1) are stored and encoded video data is decoded to form decoded video data to be output for display. A selected portion (12) of the stored chunks (12, 14) or selected sub-chunks (25, 27) of the stored chunks (20, 22) for a previous, already played out part (3) of the streamed video bitstream (1) is or are discarded while keeping selected stored chunks (14) or selected sub-chunks (21, 23) stored as navigation tune-in points. The usage of selected stored chunks (14) or sub-chunks (21, 23) that are not discarded from the already played out part (3) of the streamed video bitstream (1) enables a low delay solution during video navigation when a user wants to jump to a previously played out position (5) within the streamed video bitstream (1).Type: GrantFiled: October 7, 2014Date of Patent: January 8, 2019Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Jacob Ström, Beatriz Grafulla-González, Richard Mitic, Thomas Rusert, Ying Wang

Patent number: 8854435Abstract: Viewer interaction herein triggers switching from a first view point to a second view point and thereby controls presentation of video sequences. Each video sequence comprises a sequence of images of one and the same subject and is associated with a respective view point. Images are obtained from a first video sequence associated with a first view point and are provided for presentation. Viewer input information is received that indicates a desire to present a second view point. In response, a start position within a second video sequence associated with the second view point is determined, and the obtaining of images from the first video sequence is discontinued as of the determined start position. Images are then obtained from the second video sequence associated with the second view point, starting from the determined start position, and are then provided for presentation.Type: GrantFiled: July 14, 2011Date of Patent: October 7, 2014Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Beatriz Grafulla-Gonzalez, Martin Pettersson

Patent number: 8571308Abstract: Processing of a digital image that has been recorded through an optical system is described, the image being in a raw format matrix of picture elements and comprising a plurality of subsets of picture elements, each subset corresponding to a color component. The method comprises analyzing values of picture elements of the color components in terms of spatial features, resulting in at least one calculated parameter that is representative of aberration caused by the optical system, and performing demosaicing of the digital image by, for each picture element under consideration, defining a kernel comprising picture elements that are to be considered during the demosaicing, the definition of the kernel being dependent on the at least one parameter that is representative of the aberration.Type: GrantFiled: September 11, 2009Date of Patent: October 29, 2013Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventor: Beatriz Grafulla-González
