RK2818 Overview
It is designed for high-end multimedia product applications such as MID, AP, GPS and Mobile TV etc. RK2818 can support decode for various types of video standards such as H.264 /RMVB/MPEG-4/AVS/VC1/MPEG-2 by software and dedicated coprocessors, and encode for some video standards by software. Specially, highest performace for video decode will reach fluent replay for video with H.264 @ 1280x720 formats.
