Abstract:
A motion picture code evaluator for evaluating, on a motion picture receiver for receiving via transmission means a motion picture code comprising a scalability code including a basic layer code and an extended layer code, the total post-transmission motion picture information amount which is based on a motion picture code loss caused by said transmission means and decoding said motion picture code, comprising, motion picture code layer separation means for separating the basic layer code and the extended layer code from the motion picture code received, basic layer loss determination means and extended layer loss determination means for respectively determining a loss of the basic layer code and the extended layer code separated by said motion picture code layer separation means, and motion picture code evaluation means for evaluating the total post-transmission motion picture information amount in accordance with the outputs of said basic layer loss determination means and said extended layer loss determination means.
