Abstract: Apparatus and methods for providing block-based layouts for non-rectangular regions between non-contiguous imaging regions in projections such as, for example, Rotated Sphere Projections (RSP). In one embodiment, methods and apparatus for selecting coding unit block sizes for non-rectangular regions disposed between non-contiguous imaging portions is disclosed. The methods and apparatus may be configured to obtain a frame of captured imaging content, the frame of captured imaging content including the non-rectangular regions disposed between the non-contiguous imaging portions; select a plurality of differing coding block sizes for each of a plurality of regions located within the non-rectangular regions disposed between the non-contiguous imaging portions; determine which one of the plurality of differing coding block sizes optimizes an encoding efficiency for the obtained frame of captured imaging content; and encode the obtained frame of captured imaging content in accordance with the determined one off the plurality of differing coding block sizes.

Abstract: Systems and methods for marking an event of interest within a spherical video segment are provided. The spherical video segment may define visual content viewable from a point of view. User input designating an event of interest within the visual content may be received. The user input may indicate a point in time in the spherical video segment and a viewing angle of the event of interest. Tag information associated with the event of interest may be generated. The tag information may identify the point in time and the viewing angle such that notification of alert information is effectuated based on a determination that the viewing angle, proximate to the point in time during a subsequent presentation of the spherical video segment, is outside a display field of view. The alert information may indicate that the event of interest is located outside the display field of view.

Abstract: Apparatus and methods for digital video data compression via a scalable, multi-resolution approach. In one embodiment, the video content may be encoded using a multi-resolution and/or multi-quality scalable coding approach that reduces computational and/or energy load on a client device. In one implementation, a low fidelity image is obtained based on a first full resolution image. The low fidelity image may be encoded to obtain a low fidelity bitstream. A second full resolution image may be obtained based on the low fidelity bitstream. A portion of a difference image obtained based on the second full resolution image and the first full resolution may be encoded to obtain a high fidelity bitstream. The low fidelity bitstream and the high fidelity bitstream may be provided to e.g., a receiving device.

Abstract: Systems and methods for presenting and viewing a spherical video segment is provided. The spherical video segment including tag information associated with an event of interest may be obtained. The tag information may identify a point in time and a viewing angle at which the event of interest is viewable in the spherical video segment. An orientation of a two dimensional display may be determined based upon output signals of a sensor. A display field of view within the spherical video segment may be determined and presented on the display based upon the orientation of the display. The display field of view may be captured as a two dimensional video segment. If the viewing angle of the event of interest is outside the display field of view proximate the point in time, a notification may be presented within the display field of view.

Abstract: Apparatus and methods for resolution based, selective retrieval, of various portions of video content for e.g., accelerated rendering. Embodiments described herein select different portions of content to retrieve at different resolutions; content of interest can be rendered at high resolution, boundary content can be retrieved and/or rendered at low resolution. By selectively retrieving and rendering the video content, a greater portion of rendering resources can be allocated to content of interest and/or rendering resources can be reduced for boundary content. Rendering resources may include (but are not limited to) processing power, device battery life, network bandwidth, device storage or latency of switching content of interest. In this manner, even platforms with limited rendering resources can provide an equivalent (if not better) user experience than much more capable prior art platforms.

Abstract: Panoramic content may be characterized by a wide field of view and large image size. Panoramic image may be mapped to cube projection. When encoding/decoding cube-projected images, the disclosure exploits content continuity between cube facets. One facet may be encoded/decoded independently from other facets to obtain a seed facet. One or more transformed versions of the seed facet may be obtained, for example, one corresponding to a 90° counterclockwise rotation, another to a 90° clockwise rotation, and one to an 180° rotation. Transformed versions may be used to form an augmented image. The remained facets of the cube may be encoded using transformed versions within the augmented image. Boundary filtering may be applied to one or more edges of one or more facets.

Abstract: Content proxy may be obtained. Content may include video captured by an action camera. Content proxy may include metadata information obtained contemporaneous with the content and stored in a session container. Content proxy may include lower data rate version of the content (thumbnails). Content proxy information may be viewed and/or analyzed in order to obtain one or more highlights. Content portion corresponding to the highlight may be obtained. Multiple versions of content proxy obtained by multiple cameras may be used to identify, display, and/or share content portions in a multi-camera/multiuser applications.

Abstract: Systems and methods for providing video content using spatially adaptive video encoding. Panoramic and/or virtual reality content may be viewed by a client device using a viewport with viewing dimension(s) configured smaller than available dimension(s) of the content. Client device may include a portable media device characterized by given energy and/or computational resources. Video content may be encoded using spatially varying encoding. For image playback, portions of panoramic image may be pre-encoded using multiple quality bands. Pre-encoded image portions, matching the viewport, may be provided and reduce computational and/or energy load on the client device during consumption of panoramic content. Quality distribution may include gradual quality transition area allowing for small movements of the viewport without triggering image re-encoding. Larger movements of the viewport may automatically trigger transition to another spatial encoding distribution.
