The WSC2000 is a high-quality, digital video processor that incorporates Weststar’ patented de-interlacing, scaling, and video enhancement technologies. The chip accepts industry-standard video formats and resolutions, and converts the input into many desired output formats. The video algorithms are highly efficient, providing excellent quality video. The chip combines many functions into a single device, including a high speed MCU, a graphic OSD, a video decoder, a tripe 10-bit Digital-to-Analog Converter (DAC), memory controller, auto-configuration, and others. This high level of integration enables simple, flexible, cost-effective solutions requiring fewer components. 规格说明芯片内置高速MCU 芯片内置位图OSD 芯片内置标准解码器芯片内置3个 10位数模转换器内置32 位SDRAM控制器芯片内置 CC/V-CHIP解码器支持 1080p/1600*1200 0.18um 芯片生产工艺 292 引脚PQFP封装芯片供电: 1.8V/3.3V 多种输入格式 576i/480i (PAL/NTSC) ITU656/601/709 数字输入接口来自PC的RGB24 位输入格式(可达UXGA 格式)数字24 位的YUV/YCRCB 输入 720p/1080i/1080p HDTV 自动检测输入格式 高质量的视频处理电路高质量的运动自适应隔行到逐行转换电路(EEPCTM) 任意比例的可编程的图像SCALER引擎帧频提升电路(专利技术) 2:2/3:2电影模式检测电路(专利技术)幅型比变换 (4:3 <–>16:9)电视静止画色彩空间转换电路图像增强电路亮度/对比度控制,色调/色饱和度控制 动态蓝电平扩展、黑电平扩展锐化、边缘增强白平衡调节 Gamma校正动态数字降噪电路高质量的去抖动电路 输出格式 480p, 576p, 720p, 1080i/1080p@50,1080i/1080p@60, and VGA to UXGA 单像素输出到UXGA,60 赫兹支持30/24/18 位的平板显示器用于CRT 的模拟RGB/YPBPR 输出 应用范围逐行扫描电视数字电视液晶/等离子电视扫描格式转换盒投影仪高清DVD、EVD |
