function description
the ms1830 is a single chip vga to av converter,which support 10-bit quality dac,cvbs and s-video output simultaneously
horizontal/vertical scaling and frame rate conversion
ms1820 horizontal/vertical scaling engine can change the video resolution,which scaling ratio from(1/8)x to 8x both for horizontal and vertical,frame tate conversion engine can change the video frame rate such as 50hz to 60hz.
osd engine
the embedded character-based osd engine supports 1 bit drcs character mode. the ms1830 supports 256 levels of alpha blending to overlay osd image on background video.
