Abstract
Abstract A transmission and/or recording apparatus for superimposing the copyright protection control information or the copyright appendage information on original signals, such as musical data or picture data, by electronic watermark processing in meeting with respective requirements. A screen displayed on the basis of picture signals as original signals is split into two layers. The first layer is further split into two areas in which the information of 10 bits or less as the copyright protection control information are superimposed by electronic watermark processing. In the second layer are superimposed 20 or more bits of the copyright appendage information using electronic watermark processing. In these first and second layers, synthesis or detection is performed using encoders and decoders having different methods or parameters.
