ABSTRACT:
A decoding signal error concealment system for concealing data which are determined as errors during the process of decoding coded image data into signals in a digital VTR system including an error correction decoder, a block data selecting unit a block data decoding unit, an address and control signal generating unit, a line memory unit and a filtering data selecting unit. The system substitutes error data with image data of the preceding frame when reproducing image data which includes error data, thus enabling substitution of image data including chrominance signals, and prevents boundary effects of the substituted image data.
