專利摘要 |
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 calcilation 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. |
