| 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 Display Format 18/24 bit RGB/YUV digital output*1 ITU-R BT.656 output*1 Support Sync-on-channel mode output (YPBPR / RGB and Analog) 10-bit DAC embedded, support analog output*2 Resolution up to UXGA (1600x1200) and 1080p (1920x1080) *3 Dither reduction*1 Line frequency enhancement Support user-defined format Programmable timing signal (sync and DE) 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 Pixel sample rate up to 165M pixels/sec Input video format auto detection Input clock phase correction ATSC format support Support up to 1600x1200@60Hz (UXGA) Non-standard input formats supported Processing Features Programmable color space conversion (sRGB, ITU-R BT.709 YUV/YPbPr, ITU-R BT.601 YUV/YCbCr 8bit gamma LUT CTI / LTI BCHS (brightness, contrast, hue, saturation) White / black / blue expanding White balance adjustment Color temperature correction 3D Motion-adaptive color collusion elimination 3D Motion-adaptive white noise reduction Peak / White noise reduction Frame rate conversion Improved motion-based de-interlacing De-interlace support NTSC / PAL / SECAM / 1080I Film mode (3:2/2:2 pull down) auto-optimizing for NTSC / PAL / 1080I Auto-switching between film mode and de-interlace ChengDu WestStarChips Co., Ltd. g g g g g g g g g g g g g g g g g g g g g g g g g g g g g g g g g g g -6- Mar 2009 Edition 2.0 WSC2800/2810 Advanced Video Format Converter g g g g g g g g g *1 Support multi-region, non-linear scalar Poly-phase programmable scalar filter Muti-window (4, 9, 16) Conversion between 4:3 and 16:9 aspects Zoom and panning for user-defined area Muti-region keystone correction Interlace scalar phase correction 16-bit DDR SDRAM memory address up to 32M byte (32M x 16bit) Memory clock speed up to 200 MHz (T.B.D.) *1 Available in WSC2810 only *2 Available in WSC2800 only *3 For analog output, consider of the panel limitation, digital output will be up to 1366x768 1.3 System Block Diagram DDR1 SDRAM (8M-Byte, 16-bit) WSC2800 / WSC2810 LSI DRAM Controller M-Bus Video Input Video Front Engine PreScalar De-interlacer / Scalar Video Back Engine Video Output P-Bus PBus Controller EOSD Engine General Controller SPI Flash (Optional*1) Data Path Control Path Figure 1-1 System Block Diagram Refer to Chapter 5 OSD Engine for details. -7- ChengDu WestStarChips Co., Ltd.
