    摘要: Methods and systems for constructing media output by combining multiple input media channels corresponding to different views of a scene. The construction involves combining channels that have different spatial ranges and/or color ranges so as to produce a constructed output having a range that is a composite of input channel spatial and/or color ranges. The constructed output is generated dynamically from available input channels in response to output requirements specifying a view defined in part by spatial and/or color parameter ranges. Available input channels are represented by a single multi-channel source object comprising a hierarchy of grouped and aligned channels, with individual media essence files at the lowest level. Input channel ranges and relationships among the ranges are specified by metadata associated with each channel. During editing, input channels may be added, removed, or changed and the range and nature of the constructed media output are updated dynamically.

    摘要: A multimedia processing apparatus, method, and non-transitory tangible computer readable medium thereof are provided. The multimedia processing apparatus of the present invention includes an interface and a processing unit. The interface receives an audio stream continuously, wherein the audio stream is defined with a time line. The processing unit performs the following operations every a predetermined time interval: (a) deciding a first portion of the audio stream with reference to a time instant of the time line, (b) calculating an energy of the first portion of the audio stream, and (c) calculating a difference between the energy and a previous energy. The processing unit decides a plurality of second portions of the audio stream and decides a beat point for each of the second portions by selecting the time instant that corresponds to the maximum difference within the second portion.

    摘要: Enables intelligent synchronization and transfer of generally concise event videos synchronized with motion data from motion capture sensor(s) coupled with a user or piece of equipment. Greatly saves storage and increases upload speed by uploading event videos and avoiding upload of non-pertinent portions of large videos. Provides intelligent selection of multiple videos from multiple cameras covering an event at a given time, for example selecting one with least shake. Enables near real-time alteration of camera parameters during an event determined by the motion capture sensor, and alteration of playback parameters and special effects for synchronized event videos. Creates highlight reels filtered by metrics and can sort by metric. Integrates with multiple sensors to save event data even if other sensors do not detect the event. Also enables analysis or comparison of movement associated with the same user, other user, historical user or group of users.

    摘要: Enables recognition of events within motion data obtained from portable wireless motion capture elements and video synchronization of the events with video as the events occur or at a later time, based on location and/or time of the event or both. May use integrated camera or external cameras with respect to mobile device to automatically generate generally smaller event videos of the event on the mobile device or server. Also enables analysis or comparison of movement associated with the same user, other user, historical user or group of users. Provides low memory and power utilization and greatly reduces storage for video data that corresponds to events such as a shot, move or swing of a player, a concussion of a player, or other medical related events or events, such as the first steps of a child, or falling events.
