Abstract
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.
