Through using for reference and demonstrating the technology of video processing system of domestic and foreign , author has put forward a set of video processing system schemes suitable for the china " s actual conditions . by using the digital technology , such as digital encode - decode , digital phase - locked , digital filter , digital image storing , the system schemes realizes tv signal noise reduction and time error elimination in real time , and makes the system be a integrated noise reduction and time based corrector really 通过借鉴和论证国内外时基校正和视频降噪的相关技术,作者提出了一套适合于中国国情的视频处理系统软、硬件方案实现模拟电视的信号数字转换以及利用数字编解码、数字锁相、数字滤波、数字图像存储等数字技术来实现电视信号实时去噪和消除时基误差,使系统真正做到集时基校正与降噪一体化。
