Abstract
In a DVD video player with a built-in CD-R drive, until it reaches the state that the data of an optical disk can be reproduced, the output is switched into the reproduction output from a flash memory, a record medium that is quick to start reading. This makes it possible to develop user interfaces such as: voluntarily reproducing an audio information from the flash memory to add music sounds or sounds with special effects to the screen saver, in replacement of the optical disk drive that cannot read data during the screen saver being in operation or being in standby; reproducing the sounds with special effects; reproducing click sounds in response to a key input from the key or the remote control unit; and announcing to inform of the state to the user.
