Abstract
Abstract A digital convergence apparatus detects the presence/absence, frequency and the number of scanning lines of inputted synchronizing signals, performs an interpolation between adjusting points corresponding to the detection signal to prepare a correction data, and performs a cursor display of a center position between adjusting points, extrapolating operation control and difference data storage, writing of the same data into n-planes, and time sharing the interpolation processor so as to accommodate multimedia with a high accuracy.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
104 words
A digital convergence apparatus comprising: a generator, said generator generating a plurality of convergence adjusting points in horizontal and vertical directions on a screen of a color television receiver to perform cursor display; a memory, said memory digitally storing a convergence correction quantity for said adjusting points; a digital to analog converter, said converter converting the digital convergence correction quantity to an analog quantity; a means for inputting correction data for each adjusting point within said screen; and a cursor display area means for displaying a cursor having an area indicating a possible range of correction corresponding to quantized bits stored in said memory.
