ABSTRACT:
A partition decoder system for high definition video decoding receives an HD picture divided into a selected number of sections, each section including identification data including a start code. An FLD detects each start code and assigns a pointer. A selected number of partition decoders, corresponding to the selected number of sections, uses the pointers to select and decode a selected section of the HD picture. The selection is made according to a selected memory management scheme.
