ABSTRACT:
Apparatus is disclosed for providing error compensation for a digital video information signal and is particularly adapted for use with a PAL format video information signal. The apparatus takes advantage of sampling being done in a precise manner, i.e., at a rate of four times the chrominance subcarrier frequency of the PAL information signal, and alternately along the U and V vector axes. The apparatus generates a substitute value for a defective sample that is the average of selected samples which are in close proximity to and which are of the same type as the defective sample. More particularly, replacement samples taken along the U vector axis (U samples) are generated by averaging the nearest in proximity U samples and the replacement V samples are obtained by averaging the nearest in proximity V samples. Switching means appropriately substitute the generated values for the defective values so that V samples replace V defective samples and U samples replace defective U samples.
