    Abstract: A system and method disposed to enable encoding, decoding and manipulation of digital video with substantially less processing load than would otherwise required. In particular, one disclosed method is directed to generating a compressed video data structure that is selectively decodable to a plurality of resolutions including the full resolution of the uncompressed stream. The desired number of data components and the content of the data components that make up the compressed video data, which determine the available video resolutions, are variable based upon the processing carried out and the resources available to decode and process the data components. During decoding, efficiency is substantially improved because only the data components necessary to generate a desired resolution are decoded. In variations, both temporal and spatial decoding are utilized to reduce frame rates, and hence, further reduce processor load. The system and method are particularly useful for real-time video editing applications.

    Abstract: A spherical content capture system captures spherical video and audio content. 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. For each sub-frame, a corresponding portion of an audio track is generated that includes a directional audio signal having a directionality based on the selected sub-frame.

    Abstract translation: 球面内容捕获系统捕获球面视频和音频内容。 在一个实施例中，捕获的元数据或视频/音频处理被用于基于时间和位置信息来识别与特定用户相关的内容。 然后，平台可以从与用户相关的一个或多个共享球面内容文件生成输出视频。 输出视频可以包括诸如通常与常规相机系统相关联的非球面缩小视场。 特别地，可以从球面视频的每个帧中提取具有减小的视场的相关子帧，以产生跟踪特定个人或感兴趣对象的输出视频。 对于每个子帧，生成音频轨道的对应部分，其包括具有基于所选择的子帧的方向性的定向音频信号。
