Abstract

Methods and systems for processing digital video data are provided. In one embodiment, a method comprises capturing one or more video images and generating serial digital video signals of the one or more video images. The method further comprises filtering one or more of color, sound, and control symbols from the serial digital video signals. The method further comprises storing the serial digital video signals as a memory mapped image in one or more memories; performing one or more image enhancement operations on the memory mapped image, including one or more of digital filtering, edge detection, image cropping and image magnification; and generating second serial digital video signals of the transmitted memory mapped images by one or more of, restoring control symbols, inserting blank color data samples, inserting blank sound data samples.
