-15- ABSTRACT PROGRESSIVE SCAN TELEVISION RECEIVER WITH ADAPTIVE MEMORY ADDRESSING A video input signal (S2) is stored in a memory (24) and read twice during a line-interval to provide a processed video output signal having a doubled line rate (2FH) for display on a display device (18) having a doubled horizontal sweep rate (2FH) thereby providing a progressively scanned image having reduced visibility of line structure. The last address written in memory is used to control the starting time of the second memory read operation This reduces the tendency of visible artifacts to occur in cases where the video input signal is "non- standard" in the sense that the ratio of the color subcarrier frequency with respect to the line rate is such that there may not be a fixed number of color subcarrier cycles per line.
