Painting in a Composite Frame Buffer
The use of a four-field composite frame buffer for computer graphic applications such as painting, texture mapping, image processing, and synthetic video generation is described. The technique avoids the encoding and decoding problems of component frame buffers with composite input and output, while at the same time reduces the complexity and cost of the hardware. The all-digital approach uses digital decoding and encoding implemented in software. The frame buffer can create all colors in the NTSC color space, grab images in real time, and create complex anti-aliased, smooth-shaded images. It requires only one-half the memory bandwidth of other systems with similar capabilities.
