Abstract
A multimedia coding system has different picture qualities with different coding characteristics. It is done through a scaleable fractional motion estimation (FME) in H.264 and a block size trend prediction FME. Three quality levels are thus obtained. The first level processes a complete calculation and obtains a best picture; the second level, fewer calculation with a low power consumption and an acceptable picture quality; and the third level, fewest calculation with a fastest speed. And the present invention is suitable for hardware design to obtain a high efficiency, a low cost and a high performance.
