<P>PROBLEM TO BE SOLVED: To prevent occurrence of a malfunction caused by directly operating a button, of which the direct operation is not estimated, as a hidden button when an operation unit such as a touch panel in which buttons can be directly operated is used in the BD-ROM standard on the assumption of operation input using a remote controller. <P>SOLUTION: On the basis of button related information in which information related to each button displayed on a screen is made correspondent for each button and operation input information from an operation unit, it is determined whether a button instructed by the operation is a button for which a direct instruction is not estimated. When the instructed button is a button for which the direct instruction is not estimated, a command corresponding to the instructed button is set to no execution. Thus, occurrence of a malfunction caused by operating the button for which direct operation is not estimated in unexpected timing can be effectively prevented. <P>COPYRIGHT: (C)2012,JPO&INPIT |
