Abstract
BT.656 is a wildly used digital video Stream.However,display devices,such as LCD monitor,LED display area array,as well as part of the micro-projection devices,can only be displayed directly to the video signal of the RGB color space.The conversion from BT.656 to RGB Video Stream consists processing of de-interleave,interlaced to progressive,color space conversion.BT.656 protocol was introduced,and platform based on field programmable gate array implementation of the progressive video of the 24-bit RGB color space was expounded.System on Chip which video information was stored by utilizing multi-port SDRAM timing controller,and then in turn to complete the follow-up processing was designed by Verilog Hardware Hardware Description Language.The system was verified on an independent developed Micro-Projection system,24-bit true color of resolution up to 852 × 480 at 30 frames per second in real-time processing and transmission was achieved.Then,the system is flexible,reliable,of short development cycle and cost-saving in hardware(merely accounted for 1 783 logic elements),which avoids cumbersome floating-point operations in color space conversion.
