ABSTRACT:
A decoding apparatus for use in decoding data encoded according to MPEG-1 and MPEG-2 standards. The decoding apparatus generates a signal indicating that received data is encoded according to the MPEG-2 standard if an expansion start code is contained in the input data, while a code standard signal indicating the MPEG-1 code standard is generated if no expansion start code is contained in the input data. A run level determiner outputs data from one portion of the input data as an escape code level, when the code standard signal indicates the MPEG-2 code standard, and determines the escape code level according to whether an absolute value of data within a specific bit interval contained in the portion of data is larger than or equal to, or less than, 128, when the code standard signal indicates the MPEG-1 code standard.
