摘要： A first data-recorded region is formed in one of multiple recording layers of a rewritable optical disc before a second data-recorded region is formed therein. A first on-disc position is related to an innermost position within the second data-recorded region. Information is reproduced from a recording management area of the disc. A second on-disc position is derived from the reproduced information. The second on-disc position is in substantial coincidence with an outermost position within the first data-recorded region. The first on-disc position and the second on-disc position are compared to decide whether an unused portion is present in or absent from a region therebetween. When the unused portion is present, padding data is recorded thereon. The second on-disc position is updated into substantial coincidence with an outermost position within the second data-recorded region. The information in the recording management area is updated to reflect the updated second on-disc position.

摘要： Code words, which correspond to orthogonal-transform-resultant coefficients having order numbers equal to or higher than an order number “n+1”, are deleted from code words composing each 1-intra-frame segment of an input digital picture signal to generate special picture data with a frame period NS on the basis of the input digital picture signal. Estimation is made as to a code amount CF(nmin) of special picture data generated by deleting code words, which correspond to orthogonal-transform-resultant coefficients having order numbers equal to or higher than an order number “nmin+1”, from code words composing a 1-intra-frame segment of the input digital picture signal, where “nmin” denotes a lower limit of an order number “n”. The frame period NS of the special picture data and a target code amount C are decided so that the estimated code amount CF(nmin) will be equal to or smaller than the target code amount C. The input digital picture signal is recorded on a recording medium. The special picture data is recorded on predetermined positions in the recording medium.

摘要： An optical disc of a recordable type or a rewritable type has a plurality of recording layers including first and second recording layers. A laser beam is applied to the second recording layer through a used area in the first recording layer to record arbitrary information on at least a part of the second recording layer. The used area in the first recording layer has been used for at least one of information recording and data recording. Positional information is generated. The generated positional information is of a blank area in the second recording layer which occurs due to the presence of an unused area in the first recording layer. The blank area adjoins the unused area. The generated positional information is recorded on a predetermined area in the optical disc.

摘要： Test signals are recorded on a prescribed area in an optical disc. The prescribed area is scanned by a laser beam while the power of the laser beam is changed among different DC erasing values. The different DC erasing values are assigned to the recorded test signals, respectively. The recorded test signals are reproduced from the prescribed area to obtain reproduced signals. Parameter values of the respective reproduced signals are detected. The detected parameter values correspond to the different DC erasing values, respectively. Among the detected parameter values, a detected parameter value is decided which matches a target. One corresponding to the decided parameter value is selected from the different DC erasing values. A prescribed coefficient and the selected DC erasing value are multiplied to calculate an optimum level of an erasing power of the laser beam.

摘要： An image information compression and decompression device produces a low frequency band signal suitable for reproduction of a standard definition (SD) image and a combined high frequency band signal which, when processed together with the low frequency band signal, can reproduce a high definition (HD) image. These signals are derived from a high definition (HD) image signal and are subjected to motion compensation prediction coding. An I picture of the HD image is divided into a plurality of band signals which are coded and quantized by a coding/quantizing circuit. Thus, an intra-plane coding of the divided image signal is performed for the I picture. For a P picture of the HD image, a low frequency band signal is derived and a combined high frequency band signal excluding the low frequency band signal is produced. The low frequency band signal and the combined high frequency band signal are subjected to motion compensation prediction coding by a motion compensation prediction coding circuit. This results in a system which is compatible to both standard and high definition television systems.

摘要： A standard definition (SD) corresponding image is derived from a high definition (HD) image by performing a vertical line sub-sampling for every field with a ratio of an N:1, where N is an odd number greater than 1. One of the simple sub-sampling methods, the pyramidal coding method and the sub-band coding method may be used. For first fields, every third line is derived. For the remaining fields, every third line positioned at the center of the lines derived from the first field is derived by taking positional relation thereof on a reproduced image screen into consideration. As a result, it is possible to obtain an SD corresponding image having an unbroken interlace structure.
