<p><P>PROBLEM TO BE SOLVED: To allocate a large code amount to an important scene of a high viewing value by taking into consideration the degree of importance of semantic contents of moving images in re-encode dubbing by a moving image encoding system. <P>SOLUTION: When encoding video signals (110) and sound signals (111) supplied from the outside and recording them in a first recording medium (102), the video signals and the sound signals to be recorded are divided into respective prescribed sections, the feature of the sound of the sound signals in each section is extracted (143), and an encoding rate is decided on the basis of the feature of the sound indicated by the sound signals in each section (120, 121, 122, 123). When performing dubbing from the first recording medium (102) to a second recording medium (103), encoding is performed by the previously decided encoding rate (112, 113). <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
