Video system performing non-uniform interpolation of color space signals and method of using same
A real-time video system which performs non-uniform interpolation between adjacent vertical scan lines is presented. The video system includes a converter, a memory, an enhanced-video circuit, and a sync generator. The video system decodes and digitizes an analog composite video signal, such as an NTSC, PAL, or SECAM signal, and generates a digital video signal having a greater number of horizontal scan lines than the analog video signal. The video system is programmable to allow a different number of scan lines in the output digital video signal.
