摘要： A disk cartridge and a disk device for receiving the disk cartridge to enable recording and/or reproducing of information from or on a disk housed within the disk cartridge. The disk cartridge includes a disk in which information is recorded and/or reproduced, a case for housing the disk which case has opposite faces including a window in a respective face for exposing a part of the disk therethrough. A shutter is mounted with respect to the case so as to open or close a window of a respective face of the case with the shutter being movable in opposite directions with respect to the window from a position in which the window is closed to a position in which the window is open. The disk cartridge may include an openable part of the case for enabling the disk to be taken in and out of the case through the openable part thereof and a discrimination arrangement for enabling discrimination of different types of disk cartridges from one another. The disk cartridge may be arranged to enable exchange of disks of a same or different format including CD (compact disk), DVD (digital video disk) and PD (phase change disk) and the discrimination arrangement enables prevention of a disk cartridge of one different type from being erroneously inserted into a disk device receiving apparatus which is not compatible for the different type of disk cartridge.

摘要： A data embedding method and apparatus and a data reproducing method and apparatus are provided which can apply a digital watermark to various contents. Instead of embedding watermarking information in respective pixels or by using a relation between pixels, the watermarking information is embedded as a position pattern of changed pixels in the contents. Reliability comparable with conventional techniques can be obtained irrespective of a change in a smaller number of pixels for the contents.

摘要： Transmitting and recording methods, a reproducing method, and a reproducing apparatus of compressed video and audio signals which can easily realize a retrieval on a picture group unit basis. Packs are formed from a stream of compressed video and audio data and independent data. The pack is divided into a minimum unit of a data structure peculiar to a medium. When transmitting through or recording on the medium, information indicating whether or not a boundary of a picture group exists in the minimum unit is described in a sub information portion in a frame signal and is transmitted or recorded. Upon reproduction, by using the information which had been added to the sub information portion and was transmitted or recorded, the video data can be retrieved at a high speed every predetermined unit.

摘要： An optical disk recording thereon compressed moving picture data and an optical disk reproduction apparatus each capable of easily effecting trick play such as high speed reproduction and a retrieval operation at a high speed. Additional information necessary for trick play is recorded in an arbitrary area of an optical disk such as a TOC (Table of Contents) or a leading sector (sector 0) of the disk, and a sector address is added to each sector. To conduct trick play, an I picture, a P picture and a B picture contained in a GOP layer inside a bit stream of compressed image data are extracted and reproduced in accordance with a reproduction speed by looking up a trick play table.

摘要： An apparatus for recording and reproducing digitally compressed data in the form of divided data in and from a recording medium. A data processing circuit adds reference time information indicating an output reference time during a reproducing process to each of the divided data in the digitally compressed data. A recording circuit records the divided data with the added reference time information in the recording medium. A reproducing circuit reproduces the divided data with the added reference time information from the recording medium. A rearranging circuit rearranges and outputs the reproduced divided data on a time axis according to the reproduced reference time information such that a time interval between adjacent divided data as outputted from the rearranging circuit is equal to a time interval between respective output reference times of the adjacent divided data.
