Abstract
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.
