<p>A digital watermark embedding apparatus which generates an output image signal by embedding a digital watermark signal in an input image signal which is generated by telecine conversion based on insertion of a repeat field, comprising: detecting means (23) for detecting a repeat field from the input image signal, embedding means (11) for embedding in the input image signal the same digital watermark signal as a digital watermark signal embedded in a precedent field with respect to the repeat field.
