Apparatus for concealing error of moving pictures transform coding.

摘要

An apparatus for concealing an error of a moving pictures transform coding includes the first concealment circuit (19) for analyzing data according to a type of the data, the data being error-detected but not corrected by an error correction decoding by the decoder (12), for replacing the data with a specific data according to the analyzed result by using a predetermined method, and for outputting a specific signal therefrom, and the second concealment circuit (22) connected to the first concealment circuit (12) for replacing reproduced pixel values of an error-occurred block with reproduced pixel values of a previous frame according to the signal output from the first concealment circuit (12) in case that the data being error-detected but not corrected is data of a predetermined frequency component or data of an additional information.
