Method for reducing the interference signal of digital data-reduced television signals

摘要

In this method, the picture elements are in each case temporarily stored for the duration of one television frame and are compared with the last picture elements received. If the difference in the amplitudes of the picture elements exceeds a predetermined threshold value, the last picture element received is forwarded unchanged; if, however, the difference is below this threshold value, a new picture element is calculated, the amplitude of which is between the two picture elements of two successive television frames.
