Method for scanning a reference macroblock window in a search area
A motion estimation technique compares a current macroblock with different reference macroblocks in a reference frame search area. A motion vector for the current macroblock is derived from the reference macroblock most closely matching the current macroblock. To reduce the number of instructions re...

| Zusammenfassung: | A motion estimation technique compares a current macroblock with different reference macroblocks in a reference frame search area. A motion vector for the current macroblock is derived from the reference macroblock most closely matching the current macroblock. To reduce the number of instructions required to load new reference macroblocks, overlapping portions between reference macroblocks are reused and only nonoverlapping portions are loaded into a memory storage device. |
