Abstract
A system for expanding/compressing a video signal includes a dual-port memory having read and write address inputs and a video signal input. A pixel counter provides a pixel location signal to the write address input of the dual-port memory, and to a programmed memory device (e.g., a PROM) including a look-up table. The memory device is programmed to provide a time expanded/compressed version of the pixel location signal in accordance with a programmed time expansion/compression factor, which is applied to the read address input of the dual-port memory. A time expanded/compressed video signal is developed at the output of the dual-port memory.
