Abstract
An error detection method of a variable-length coding (VLC) code stream includes at least the following steps: decoding a data frame of the VLC code stream; and determining whether the data frame is erroneous according to length information of the data frame and a bit number of decoded data of the data frame. According to the method, the present invention realizes the objective of performing error detection upon data frames during the decoding process.
