DEVICE AND METHOD FOR CONCEALING AN ERROR |
摘要 |
<p>A device for masking a fault in a faulty or potentially faulty information unit generates output values of a forward decoder (14) and of a backward decoder (16), which differ from one another thereby indicating (18) a fault masking area. The different values for one and the same information unit are checked with regard to a predetermined criterion in order to select (22) the value that fulfills, i.e. is plausible for, the predetermined criterion. Thi s enables, without impairing a compression rate, an elimination or reduction o f the continuation faults introduced during a decoding of blocks comprised of reversible code words of a variable length.</p> |
