Videosignalverarbeitungssystem bzw. Videosignalverarbeitungsverfahren

摘要

A video signal processing system for processing a video data VIN and graphic data DmuP includes a filter unit, which receives the video data VIN. The filter unit filters the video data VIN to convert the video data VIN into video pictures formated with a different number of columns and/or lines, and provides a filtered video signal indicative thereof. The filter unit buffers individual pixels and/or lines in a first memory device. A second memory device receives and stores the graphic data DmuP and the filtered video signal and provides stored signals indicative thereof. A third memory device is connected to the second memory, and stores data received from the second memory device. A mixing unit receives and mixes the stored graphic data and the stored filtered video data to provide a video output signal VOUT.
