摘要： An information recording apparatus for continuously recording information without losing any information even if the apparatus temporarily falls into a recording-disable state owing to the shock externally applied, etc. is provided. A disability detector for detecting the recording-disable state is provided in the information recording apparatus, thereby interrupting the recording operation and the reading operation from the buffer memory under the recording-disable state, and making a coding rate reduction controller instruct a coder to temporarily reduce the coding rate of the input information. A remaining capacity detector is provided for monitoring the remaining capacity in the buffer memory and instructing the coder to temporarily reduce the coding rate of the input information when the remaining capacity becomes a predetermined value or less. As a result, the reduction in the remaining capacity of the buffer memory under the recording-disable state is prevented. When the overflow of the buffer memory is detected, the information after the generation of the overflow is controlled to be overwritten on a part of the data already written into the buffer memory. The variation history of the case where the recording data amount is varied by the coder because of the variation in the coding rate of the input information or the overwriting operation in the buffer memory is controlled to be recorded on the disk as rate variation management information. By dividing the recording area on a disk-shaped information recording medium into an inner circumference and an outer circumference and recording on the outer circumference after the return from the recording-disable state, the recording transfer rate after the return becomes higher.

摘要： A method for encoding a picture based on an intra-picture coding and an inter-picture prediction coding having an absolute value of a maximum range of motion compensation between continuous pictures in terms of time being H pixels (H: a positive integer) in a first direction and V pixels (V: a positive integer) in a second direction, the method includes the steps of: receiving a picture and judging whether the picture is directly/indirectly referred to by a further picture among the continuous pictures in terms of time or not; determining a maximum distance L (L: a positive integer) between the picture and the further picture directly/indirectly referring to the picture; dividing the picture into a first to an Nth sub-pictures (N: an integer equal to or larger than 2), a size of the first to the Nth sub-pictures being larger by at least L.times.V pixels in the first direction or at least L.times.H pixels in the second direction as compared with a region of a case where the picture is equally divided into N regions which do not overlap each other; generating a first to an Nth code sequences corresponding to the respective first to the Nth sub-pictures by encoding the first to the Nth sub-pictures based on the intra-picture coding and the inter-picture prediction coding; and adding information indicating positions of the first to the Nth code sequences in the picture.

摘要： A formatter 2s13 is provided and, when a code sequence which matches a part (‘00’) of the head of a predetermined code sequence detected by a start code prefix detection unit 2s3, is detected, the start code prefix detection unit 2s3 detects the residual part (‘00’, ‘00’, ‘01’, ‘E0’) of the detected predetermined code sequence to detect a pattern of (‘00’, ‘00’, ‘00’), and the formatter 2s13 outputs one (‘00’). After the boundary of packets is defined, amongst data which are not transferred to a decoding buffer 2s9, data corresponding to code sequences other than the code sequence (‘00’, ‘00’, ‘01’, ‘E0’) indicating the packet boundary are output to the decoding buffer 2s9. Therefore, when separating a coded and multiplexed signal, control of an input buffer reading control circuit 2s4 is simplified, and thereby the hardware scale is reduced, resulting in an inexpensive apparatus for reproducing a digital code sequence.

摘要： An image signal reproduction apparatus and an image signal reproduction method that can reproduce video signals at high speed with stability. A skip decoding field counter is set on the basis of a factor by which the reproduction speed is multiplied and the number of fields included in one frame image. When decoding of coded data corresponding to one frame to be decoded is completed, it is judged whether the skip decoding field counter is larger than zero or not. When the counter is larger than zero, the number of fields corresponding to a picture to be skipped is subtracted from the counter, and when the picture to be skipped is I or P coded data, the decoding is instructed, while when the picture is B coded data, the skipping is instructed. These processes are repeated until the counter becomes 0 or smaller.

摘要： An optical disk comprising a disk-like body having two base plates made of synthetic resin and two recording layers formed on the base plates, respectively. The body is formed by bonding the base plates, with a spacer interposed therebetween, such that the recording layers face each other. The disk further comprises two centering members, each projecting from the surface of the center portion of one base plate. Each centering member is made of synthetic resin, and one magnetic member is mounted on the centering member. The centering member is inserted in a hole formed in the center portion of the body. The centering member has a center hole defining the center of rotation of the body, and also three projections formed in the surface thereof which faces away from the recording layer. The magnetic member has three engaging holes and is mounted on the centering member, with the projections of the centering member fitted in the engaging holes. Since the optical disk has magnetic members, one on each surface, it can be attracted to the turntable of a drive mechanism by means of the magnetic force exerted by the magnet fitted in the recess formed in the surface of the turntable.
