Abstract
System and method for asynchronous transmission of video images such as from a sending to a receiving terminal or from a sending processor to a storage medium like videotape. The system receives moving picture image information such as analog video digitized into 2D bitmap data and employs a modeling system such as a triangulated mesh modeling system to create an initial image consisting of a compact set of N elements (such as the data points of a triangulated mesh) where the number of elements is less than the number of elements necessary to display the image. In the exemplary embodiment the model elements are bitmap pixel assignments, however other elements such as wavelets, or Fourier component elements, or iterated function system (IFS maps) could also be used. As the images of the moving picture change, the sending computer compares data for each new image against the current model elements and will add elements to or remove elements from the model to update the model to make it current with the new image. The sending computer outputs a sequence of commands to replicate the model building and subsequent updating either to a receiving terminal (which displays the moving image i…
