ABSTRACT:
The invention concerns the simultaneous display of video data and text data on a computer display. The invention stores both types of data in display memory. Transition codes mark the separation between the two types. The invention converts each type of data into signals which a CRT display can understand. The invention changes the type of conversion, as appropriate, when transition codes are reached.
