Abstract: Disclosed herein is an apparatus and method for providing additional information to an FU in a reconfigurable codec. The apparatus includes a syntax parser, a prediction mode converter unit, and an inverse prediction unit. The syntax parser parses the encoding type value of a multimedia bit stream and a first prediction mode value from the multimedia bit stream. The prediction mode converter unit converts the first prediction mode value into a second prediction mode value corresponding to the encoding type value. The inverse prediction unit determines an inverse prediction operating mode based on the second prediction mode value.
