Abstract
This invention discloses a system for manipulating color television images transmitted in the NTSC system of television. Manipulation is by known methods which involve storing in a memory picture data as transmitted in the television signal and restructuring the memory addresses to achieve the desired special effects. Unlike other systems, however, the data is stored in its composite form consisting of a luminance component and color information related to the phase and frequency of a subcarrier. The samples are taken at specified intervals and associated in groups. The samples in a group are mathematically combined in such a manner that the color component values are not affected by address manipulation. After manipulation the signal data is restored to its luminance and color components by a method which does not involve the phase or frequency of the subcarrier. These components are then recombined into a standard NTSC signal which will produce a manipulated display in color on the television screen.
