Information recording medium, information recording method, information recording apparatus and information reproducing apparatus

Abstract: An information recording medium of the present invention includes: a volume space in which user data is recorded; a spare area including a replacement area which may be used in place of a defective area included in the volume space; and a defect management information area in which defect management information for managing the defective area is recorded. The defect management information includes status information indicating whether the defective area is replaced by the replacement area.

Semiconductor memory card access apparatus, a computer-readable recording medium, an initialization method, and a semiconductor memory card

Abstract: A predetermined number of erasable blocks positioned at a start of a volume area in a semiconductor memory card are provided so as to include volume management information. A user area following the volume management information includes a plurality of clusters. A data length NOM of an area from a master boot record & partition table sector to a partition boot sector is determined so that the plurality of clusters in the user area are not arranged so as to straddle erasable block boundaries. Since cluster boundaries and erasable block boundaries in the user area are aligned, there is no need to perform wasteful processing in which two erasable blocks are erased to rewrite one cluster.

Active matrix liquid crystal display having electric fields parallel to substrates

Abstract: In an active matrix liquid crystal display, common electrodes and pixel electrodes are respectively formed parallel to each other and have substantially herringbone shapes Areas of first display regions formed between the common electrodes and the pixel electrodes and disposed at one side of the inflection points of the herringbone shapes are substantially the same as those of second display regions disposed at the other side When electric fields substantially parallel to surface of an array substrate are applied between the pixel electrodes and the common electrodes, orientations of liquid crystal molecules in the first and second display regions move in opposite directions Coloring of image corresponding to angle of view due to the movement of the orientation of the liquid crystal molecules is compensated

Motion compensated prediction interframe coding system

Abstract: A motion compensated prediction interframe coding system which first measures characteristics regarding the fineness of a pattern or texture of a picture, which is represented by an input television signal and is divided into a group of continuous blocks each quantized by using a quantization step size, and changes the quantization step size into a smaller one if quantizes a block having a picture pattern or texture finer than patterns of the other blocks. Thereby, an amount of generated codes can be limited but a motion compensated prediction frame coding operation can be performed without degrading the fineness of the texture of the original input picture.
