Abstract
A method of and apparatus for storing two scan lines of encoded video information for the purpose of writing said information into a main video memory such that the two lines may be transferred to main video memory during horizontal blanking periods when the main video memory is not being read for the purpose of forming a manipulated image on the screen. Two consecutive horizontal blanking periods are used to complete the transfer of each stored line. Further circuits are provided for altering addresses to the main video memory which is properly segmented for the purpose of extracting the target pixel information and the information of several surrounding pixels. The purpose of such access is to supply a pixel interpolator with enough information to construct a proper screen image of the target pixel.
