Mar 2009 Edition 2.0 WSC2800/2810 Advanced Video Format Converter 1 General Description 1.1 Introduction WSC2800 series is an advanced video format converter, which converts digital inputs into multiple formats. The series has two members. WSC2800 converts into analog output (CVBS and RGB). WSC2810 outputs digital forms (RGB and YUV). The series supports a wide range of configurable formats, with both SD (standard definition) and HD (high definition) input supported. So that, the series can be applied to many high-speed and high-quality video conversion applications 1.2 Features Input Format ! 24-bit interface in total ! 24/16-bit ITU-R601/709 YUV/YCrCb ! 24/16-bit ITU-R601/709 YPrPb ! 8/16-bit ITU-R656/709 YCrCb ! 24-bit RGB !
