    • A moving picture expert group 2(MPEG-2) encoder pre-processor for processing split picture video of standard definition (SDTV) and high definition television (HDTV). The MPEG-2 encoder pre-processor includes signal separation and synchronizing signal detector, multiplexor, and video processor. The pre-processor is capable of processing both of SDTV video and HDTV split picture video by performing the processes such as 4:2:2/4:2:0 conversion, pre-processing adaptive filtering and scene change detection, so as to simplify the compression of the video from the input video signals. Accordingly, there is no need to develop pre-processors for SDTV and HDTV, individually.
    • 用于处理标准清晰度(SDTV)和高分辨率电视(HDTV)的分割图像视频的运动图像专家组2(MPEG-2)编码器预处理器。 MPEG-2编码器预处理器包括信号分离和同步信号检测器,多路复用器和视频处理器。 预处理器能够通过执行诸如4:2:2/4:2:0转换,预处理自适应滤波和场景变化检测等处理来处理SDTV视频和HDTV分割图像视频,从而简化 从输入视频信号压缩视频。 因此,不需要单独开发用于SDTV和HDTV的预处理器。
