A disk device controller ( ) performs reading/writing of data and management information from/to a first disk device ( ) and a second disk device ( ). The first disk device ( ) and the second disk device ( ) hold their device information and storing the management information and the data from the disk device controller ( ). A reference device information holder ( ) holds previously set reference device information peculiar to the device. A master disk decider ( ) decides which one of the first disk device ( ) and the second disk device is the master disk, based on the device information and the management information held in the first disk device ( ) and the second disk device ( ), and the reference device information held in the reference device information holder ( ).

Every frame represented by a moving picture signal is divided into blocks. Calculation is made as to a number of pixels forming portions of a caption in each of the blocks. The calculated number of pixels is compared with a threshold value. When the calculated number of pixels is equal to or greater than the threshold value, it is decided that the related block is a caption-containing block. Detection is made as to a time interval related to the moving picture signal during which every frame represented by the moving picture signal has a caption-containing block. A 1-frame-corresponding segment of the moving picture signal is selected which represents a caption-added frame present in the detected time interval.

A genetic algorithm executing device, in which search of a genetic algorithm is improved, sets a distribution of characters at each position of character strings represent candidates of solution, obtain the degree of disorder at each position by the distributions of characters, set a larger mutation rate at the position of which degree of disorder is higher. This device performs a mutation operation on the character strings according to the mutation rates. This device generates the new character strings by selecting positions of which degrees of disorder are higher than a predetermined value, and changing the character at the selected positions.
