Abstract: A replay device includes a flash memory, a setting means, and a test result output unit. A device key for copyright protection is recorded in the flash memory. When a predetermined actuation input is received, the setting means sets the device to a test mode in which it is tested whether or not the device key is recorded. And, when the test mode is set, the test result output means tests whether or not the device key is recorded in the flash memory, and outputs a screen with the result of the test. Moreover, the test result output means displays the test result by changing a background color of the test result screen, according to the presence or absence of the device key.

Abstract: When a break in data is detected by a detection unit, an audio output stoppage command unit commands a digital audio processing device connected to an audio output unit to stop output of audio. A sampling frequency checking unit checks whether or not the sampling frequency of the audio data before the break, and the sampling frequency of the audio data after the break, are the same. When the sampling frequency checking unit detects that these sampling frequencies are the same, an audio output stoppage elimination command unit waits until a fixed time period has elapsed, and then returns the reading position upon the optical disk at which the reading unit reads in data to a position directly after the break, and also commands the digital audio processing device to eliminate the stoppage of output of audio.

Abstract: A data reproducing apparatus includes a receiver receiving the content and outputting the received content to an image display apparatus prepared in advance, and a transmitter transmitting the content to the receiver when authentication of the receiver is successful. Before transmitting the content, the transmitter transmits a request to start authentication to the receiver and executes an authentication process after a predetermined time. When the receiver cannot be authenticated, the transmission of the request to start authentication and the execution of the authentication process are repeated. Here, the predetermined time is variably set according to the number of times the request to start authentication is transmitted and the authentication is executed.

Abstract: A controller compares hardware structure information stored in a nonvolatile memory and hardware structure information of an updated program obtained from an interface unit, and transfers the updated program to the nonvolatile memory to change a current program when a result of the comparison exhibits matching. When a controller determines that a user must determine execution/nonexecution of rewrite processing, the controller instructs the display unit to perform display, and performs the rewrite processing according to a user's instruction received from an input unit. The program can be updated appropriately corresponding to various conditions such as improvement in performance of the device, changes in operation environment and others determined by a user. Accordingly, it is possible to provide an information processing device, which can update a control program even in the case where the device has a different structure, when the user determines that such updating is allowed.

Abstract: A CPU obtains select information from a flash memory. The CPU provides a reproduction instruction for reproducing only data selected according to the select information. The decoder unit reproduces data in response to a reproduction instruction, and provides a reproduction result. When the reproduction result indicates non-reproducibility, the CPU changes the select information. The data indicated as non-reproducible data is no longer reproduced in subsequent reproducing operations, and only the reproducible data will be reproduced. Therefore, it is possible to provide a data reproducing device that can read and reproduce only the correctly reproducible data from the data recorded on a record medium.

Abstract: An information reproducing apparatus for reproducing an audio file and a still picture file recorded in a recording medium capable of recording the audio file and the still picture file, includes a reading unit that reads audio and still picture folders containing audio and still picture files recorded in the recording medium, a first display unit that displays lists of audio and still picture folders read by the reading unit on a left screen, a first selection unit that selects audio and still picture folders from the lists of the audio and still picture folders displayed by the first display unit, a second display unit that displays the audio and still picture folders selected by the first selection unit on a right screen, and a reproduction unit that reproduces simultaneously the audio and still picture files within the audio and still picture folders selected by the first selection unit.

Abstract: An optical disk reproducing apparatus includes a flash memory, and a system controller. Preferably, the flush memory stores a firmware, initial setting information, user setting information and resume information, and the system controller divides an area of the flush memory into blocks, provides the block with a data storage part and a data management part to store data management data corresponding to the data storage areas and representing whether data is valid, determines whether data management data is 0000H when starting a data rewriting processing, initializes data within a block when the data management data is 0000H, retrieves a non-use data storage area where data management data is FFFFH when all the data management data are not 0000H or when data within the block are initialized, writes update data in the non-use data storage area, and sets data management data corresponding to the non-use data storage area to 0000H.

Abstract: A bread maker for baking a bread, having a memory for memorizing appropriate processing time data previously for kneading, rising and baking dough in accordance with a ratio of water to the weight of the ingredients. The data includes plural levels to be operated. In the bread maker, a ratio of the weight of water to the weight of the ingredients is calculated based on the weighed value, and which level the ratio belongs to is judged. Then, appropriate processing time for kneading, rising and baking in accordance with the ratio are set automatically, so that high-quality bread can be always made.
