Abstract: An information processing apparatus includes: a display control means for controlling display of a GUI for operating a first apparatus including buttons operated when opening and closing a tray; and a processing means for performing processing by receiving an instruction from the first apparatus or for transmitting the instruction to the first apparatus, wherein the GUI includes graphics of a second apparatus obtained by copying out the first apparatus, and the second apparatus includes graphics corresponding to the tray and the button, when the button in the second apparatus is operated, the display control means controls graphics in which the tray is opened or closed in the second apparatus, and when the button provided in the first apparatus is operated, the processing means instructs the display control means to control graphics in which the tray is opened or closed in the second apparatus.

Abstract: Data is arranged to one block obtained after a CIRC process so that a predetermined data pattern is recorded into a predetermined portion on a disc. By tracing back an encoding step of a Cross-Interleave Reed-Solomon Code (CIRC), a layout of recording data of one block before the CIRC process for allowing the predetermined data pattern to be recorded into the predetermined portion is obtained. An error correcting process of a CD-ROM mode 1 is executed. If a position of a parity coincides with data for forming the predetermined data pattern, a value of user data of an encoding sequence to form the parity is changed. After error correction encoding of a CD-ROM is executed, encoding of the CIRC is executed to the recording data of one block.

Abstract: In a signal processing apparatus, when a luminance signal in a first numeric range is assigned to an integer value in a second range narrower than a first range representable by predetermined bits, and a luminance signal and color-difference signals are outputted under a predetermined standard in which a color-difference signal in a second numeric range is assigned to an integer value in a third range narrower than the first range, the luminance signal in the first numeric range is assigned to an integer value in a fourth range between the first and second ranges; the color-difference signal in the second numeric range is assigned to an integer value in a fifth range between the first and third ranges; and the fourth range is adjusted in a range between the first range and second range, and the fifth range is adjusted in a range between the first and third ranges.

Abstract: A display control apparatus includes: an input means for inputting an image of a compression target; a comparing means for comparing an input image inputted from the input means with a decompressed image that is obtained by decompressing a compressed image obtained by compressing the input image; an image processing means for changing a pixel value of a predetermined pixel of the decompressed image to a predetermined value based on a compared result by the comparing means; and a display means for displaying the decompressed image in which a pixel value is changed by the image processing means.

Abstract: A recording method for converting m-bit data into n-bit (where n>m) bit data whose run length is restricted and recoding the converted data on a recording medium, the recording method comprising the steps of when at least preceded data is data containing a special data pattern, lightening the restriction of the run length; and recording data so that the cumulative value of DC components per unit time increase when the data is reproduced in the state that the run length is restricted.

Abstract: A recording method for converting m-bit data into n-bit (where n>m) data whose run length is restricted and recording the converted data on a recording medium, the recording method comprising the step of selecting first n-bit data according to an immediately preceded n-bit data, first n-bit data immediately followed thereby, and second n-bit data immediately followed thereby so that the cumulative value of DC components per unit time becomes small.

Abstract: A recording method includes the steps of generating recording data in such a manner that, when m-bit data is converted into a data symbol of n bits (m<n), and connection bits such that the summed value of DC components per unit time decreases are selected from among a plurality of connection bits and are added after the m-bit data symbol, the connection bits differing from connection bits which are added when the n-bit data symbol is a data symbol other than the special data symbol are added to generate recording data; and recording the generated recording data on a recording medium.

Abstract: Six record areas for predetermined data that has been encoded and digitally modulated are formed in a data record area on a disc. The record areas have different offset compensation amounts. The offset compensation amounts allow all offset amounts that may take place in an error correction code encoder to be compensated. Thus, regardless of the offset amount generated by the error correction code encoder, encoded and modulated data that has been generated by the conventional EFM modulating system and recorded in one of the record areas securely causes DSV to deviate. Each of the record areas is set to a sufficient length that allows the effect of which DSV deviates to be recognized.
