TEMPORAL SCALABILITY MODEL
•Each focal object is represented by a focal window described by three parameters:

By an associated frame (Fn), region geometry (Ân) (such as if it is an rectangular region, then shape-type, x and y coordinates of a corner, and height and width), and focal acuity parameters (An) (such as relative level of spatial bit allocation or desired temporal resolution).

• Frame Synthesis
The superposition operation is non-commutative.  This is performed by sorting the focal regions in order of their skip-rate (the focal region with maximum skip rate is committed first).
