    Abstract: A cloud video system selectively uploads a high-resolution video and instructs one or more client devices to perform distributed processing on the high-resolution video. A client device registers high-resolution videos accessed by the client device from a camera communicatively coupled to the client device. A portion of interest within a low-resolution video transcoded from the high-resolution video is selected. A task list is generated specifying the selected portion of the high-resolution video and at least one task to perform on the portion of the high-resolution video. Commands are transmitted to prompt the client device to perform the at least one task on the specified portion of the high-resolution video according to the task list. The specified portion of the high-resolution video is modified according to the task list and uploaded to the cloud. Example tasks include transcoding, applying edits, extracting metadata, and generating highlight tags.

    Abstract: A spherical content capture system captures spherical video content. A spherical video sharing platform enables users to share the captured spherical content and enables users to access spherical content shared by other users. In one embodiment, captured metadata or video/audio processing is used to identify content relevant to a particular user based on time and location information. The platform can then generate an output video from one or more shared spherical content files relevant to the user. The output video may include a non-spherical reduced field of view such as those commonly associated with conventional camera systems. Particularly, relevant sub-frames having a reduced field of view may be extracted from each frame of spherical video to generate an output video that tracks a particular individual or object of interest.

    Abstract: An image sensor compresses image data prior to transmitting the image data to a DSP. The image sensor captures light representing an image, for instance via a camera's aperture. A focal plane array converts the captured light into pixel data. The pixel data is sorted into categories, and is compressed in parallel by a compression engine. The compressed pixel data is then sent to a DSP, which may be located off-chip. The DSP then decompresses the compressed pixel data, performs image signal processing operations on the compressed pixel data, and then compresses the processed pixel data into a digital image format. The image sensor may buffer the pixel data for one or more images to accommodate for slowdown by the compression engine. The pixel data may be sorted by row and column of a pixel array. Alternatively, the pixel data may be sorted by color from a Bayer color filter.

    Abstract: Methods and apparatus for processing of video content to optimize codec bandwidth. In one embodiment, the method includes capturing panoramic imaging content (e.g., a 360° panorama), mapping the panoramic imaging content into an equi-angular cubemap (EAC) format, and splitting the EAC format into segments for transmission to maximize codec bandwidth. In one exemplary embodiment, the EAC segments are transmitted at a different frame rate than the subsequent display rate of the panoramic imaging content. For example, the mapping and frame rate may be chosen to enable the rendering of 8K, 360° content at 24 fps, using commodity encoder hardware and software that nominally supports 4K content at 60 fps.
