Comprehensive multimedia content re-purposing relating to wireless communications employs content constructs that are compact representations of the content information. For video content, the constructs are content operators that represent 2D image regions and/or 3D volumetric regions for objects within the sequence and characterized by various visual attributes, and are extracted from the video sequence by segmentation utilizing video processing techniques. The constructs are employed for intra- and inter-modality transformation to accommodate resource constraints of the mobile device.
