Publication number: 20230300346Abstract: A non-random-access video stream is received. A first image block is encoded after second image blocks according to a non-random-access processing order. View direction data is received to indicate a viewer's view direction coinciding with a location covered by the first image block. The first image block is encoded into the random-access video stream before the second image blocks in a random-access processing order. The random-access video stream is delivered to a recipient decoding device operated by the viewer to cause the first image block to be processed and rendered before the second image blocks according to the random-access processing order.Type: ApplicationFiled: August 2, 2021Publication date: September 21, 2023Applicant: Dolby Laboratories Licensing CorporationInventors: Chaitanya ATLURU, Ajit NINAN

Publication number: 20230300426Abstract: A multi-view image stream encoded with primary and secondary image is accessed. Each primary image stream comprises groups of pictures (GOPs). Each secondary image stream comprises I-frames generated from a corresponding primary image stream. Viewpoint data collected in real time is received from a recipient decoding device to indicate that the viewer's viewpoint has changed from a specific time point. A camera is selected based on the viewer's changed viewpoint. It is determined whether the specific time point corresponds to a non-I-frame in a GOP of a primary image stream of the selected camera. If so, an I-frame from a secondary image stream corresponding to the primary image stream is transmitted to the recipient decoding device.Type: ApplicationFiled: August 3, 2021Publication date: September 21, 2023Applicant: Dolby Laboratories Licensing CorporationInventors: Chaitanya ATLURU, Ajit NINAN

Patent number: 11653065Abstract: Scenes in video images are identified based on image content of the video images. Regional cross sections of the video images are determined based on the scenes in the video images. Image portions of the video images in the regional cross sections are encoded into multiple video sub-streams at multiple different spatiotemporal resolutions. An overall video stream that includes the multiple video sub-streams is transmitted to a streaming client device.Type: GrantFiled: March 15, 2022Date of Patent: May 16, 2023Assignee: Dolby Laboratories Licensing CorporationInventors: Chaitanya Atluru, Ajit Ninan

Publication number: 20220414823Abstract: Peripheral-vision expanded images are streamed to a video streaming client. The peripheral-vision expanded images are generated from source images in reference to view directions of the viewer at respective time points. View direction data is collected and received in real time while the viewer is viewing display images derived from the peripheral-vision expanded images. A second peripheral-vision expanded image is generated from a second source image in reference to a second view direction of the viewer at a second time point. The second peripheral-vision expanded image has a focal-vision image portion covering the second view direction of the viewer and a peripheral-vision image portion outside the focal-vision image portion. The second peripheral-vision expanded image is transmitted to the video streaming client.Type: ApplicationFiled: August 31, 2022Publication date: December 29, 2022Inventors: Alexandre CHAPIRO, Chaitanya ATLURU, Chun Chi WAN, Haricharan LAKSHMAN, William ROZZI, Shane RUGGIERI, Ajit NINAN

Patent number: 11290699Abstract: View direction data of the viewer is collected in real time while the viewer is viewing a first reconstructed omnidirectional image. The view direction data is sent to the video streaming server to cause generating image layers from an omnidirectional image in reference to a view direction of the viewer. The image layers comprising a focal-vision image layer and a peripheral-vision image layer. A second reconstructed omnidirectional image is generated from the image layers. The second reconstructed omnidirectional image is subsequently rendered to the viewer.Type: GrantFiled: December 14, 2017Date of Patent: March 29, 2022Assignee: Dolby Laboratories Licensing CorporationInventors: Ajit Ninan, Chaitanya Atluru

Publication number: 20210373340Abstract: A wearable device includes circuitry on substrate. The substrate is coupled to an optical element in an optical stack. A refractive index of the substrate perceptually matches a refractive index of the optical component. The circuitry is imperceptible to the viewer wearing the device, despite that the circuitry has a view of (or, as an example, an unobstructed line of sight to) the viewer's eye. The circuitry can include a camera or an emitter, or both. The camera captures one or more reflections of the emitter from the viewer's eye. In a specific embodiment, the substrate includes a waveguide, Fresnel lenses, or lens to bend light rays around from the circuitry to achieve the imperceptibility. In alternative embodiment, the circuitry can be a piezoelectric device, liquid crystal controller, or any electronic circuitry relevant for a wearable device.Type: ApplicationFiled: September 20, 2019Publication date: December 2, 2021Applicant: Dolby Laboratories Licensing CorporationInventors: Titus Marc DeVine, Chun Chi Wan, Chaitanya Atluru, Ajit NINAN
