Document Type and Number:
Japanese Patent JPH056396
Kind Code:
B2
Abstract:
In a digital video signal processing apparatus having error correcting and concealing capabilities, a video signal is converted to a digital signal and transmitted or recorded with error detecting and error correcting signals. Upon receiving or reproducing the transmitted signal, an error in th digitized video signal is detected by means of the error detecting signal, and corrected, if possible, by means of the error correcting signal. If the error is so extensive that its correction by the error correction signal is not possible, the erroneous signal is concealed by its replacement with a substantially corresponding signal of the previous field which has been stored in a suitable memory.
