为开发者设计的MPEG-1, MPEG-2 和 MPEG-4编码硬件
MVRD4400为应用开发者提供一整套Windows软件开发工具包。MVRD4400提供高质量、基于硬件的实时MPEG-1，MPEG-2 和MPEG-4编码功能，同时在MPEG编译码前具有预过滤，稳定和提高模拟输入视频的功能。
在MVRD4400中的强大的预过滤特征包括：先进的3D Y/C分离来减少色彩噪声以及改进图像质量，3D数字降噪来消除模拟视频信号中的噪音，一个线性时基校正器（LTBC）来校准任何抖动的视频图像，数字帧同步和音频增益控制。
MVRD4400：关键特性
实时编码带有准确IBP帧和VBR支持的MPEG-1,MPEG-2和MPEG-4
SDK为应用程序开发提供了向上兼容性，可以和为Canopus MVRD4000硬件开发的应用程序相容
支持模拟视频到MPEG实时采集，且具有模拟输入预过滤来清除噪音和提高源素材质量的功能
支持延时采集，这对于CCTV和监控应用来说是理想的
增强的视频叠加电路允许多个MVRD4400板在一个系统中使用，而不会影响系统整体性能
支持NTSC和PAL格式(不支持它们之间的转换)
与Canopus MediaEdge系统兼容，来用于实时视频传输和采集SDK API 函数
