Abstract
The digitized video image data stored in a video RAM in a pix-in-pix television receiver is modified by the addition of digital data from an external computer via a computer interface circuit under control of the pix-in-pix controller. The computer interface circuit is coupled to the internal controller of the television receiver via an external input terminal. The additional digital data received from the external computer may be representative of either text or graphics to be merged into the stored video image.
