An improved interface between a host computer and a tape drive emulation system includes software interfaces for communicating control, configuration, and policy data and a hardware interface for providing redundancy and fan-out between the main controller and host channels.

A digital scan converter is provided with a programmable transfer function for video display of picture elements (pixels) using a main random access memory for storing a pixel array to be read out periodically for display, and to be selectively read out while scanning for updating with a value derived from an auxiliary random access memory addressed by the composite of an old pixel value to be updated and the new pixel value. Each memory location of the auxiliary memory stores a value derived from a table defining the transfer function desired for the entire range of new and old pixel values. An alternate transfer function is stored in a second block of the memory and selectively called out by a prefix set to a 1 or 0 in the most significant bit position of the composite address word.

A technique of encoding digitized video input signals to an arrayed display memory in a manner to maximize the probability of entering the best picture element (pixel) value into a particular X,Y location by effectively dividing a pixel area into an array of subpixels, and weighting the value of pixel as a function of the position of a display vector through the subpixel array. First the location of a vector to be displayed in an X-Y coordinate system is determined, and then with respect to the subpixel array of each pixel, it is determined whether the vector traverses a core or central area, an edge or a corner. For these respective vector locations, the pixel value is weighted, for example, 100%, 50% and 0%.
