摘要： PROBLEM TO BE SOLVED: To reduce overheads during normal operation and to efficiently create snap-shots at certain designated points. SOLUTION: To update a block, the pre-update data of the block to be updated are written as a pre-update image in a log storage area 113 along with both an identifier (i node number) for identifying a file or directory including the block and the block number of the block, after which the block to be updated on a file system is updated. The snap-shots are created by restoring both the pre-update contents of the file/directory including the updated block and the directory information of a host directory including the pre-update file/directory, based on pre-update images stored in the log storage area 113 and the current image of the file system.

摘要： PROBLEM TO BE SOLVED: To provide an information processor that can predict a decoding load, in advance, from the encoding state of, for example, motion image data and to suitably start reduction of the load of a CPU.

A decoding control module 202 determines the omission level, based on the decoding load level and makes a decoding execution module 203 start decoding the motion image data. A display state monitoring module 204 monitors whether display does not have unacceptable delays, and the decoding control module 202 controls the decoding execution module 203 so as to raise the omission level, when the display has unacceptable delays, or to lower the omission level when the display has some margin.

摘要： PROBLEM TO BE SOLVED: To protect a digital content by providing a means to prevent a decoded dynamic image data from an illegal acquisition.
SOLUTION: A video decoder 32 decodes an encoded dynamic image data. An encryption portion 33 encrypts the dynamic image data decoded by the video decoder 32 partially. The dynamic image data encrypted partially by the encryption portion 33 is input into a display controller 14 through a system bus 2. A decoding portion 140 built in the display controller 14 decodes the partially encrypted dynamic image data. The display controller 14 displays a dynamic image corresponding the decoded dynamic image data on a LCD 141.

摘要： PROBLEM TO BE SOLVED: To provide an information processing apparatus capable of smoothly performing decoding of a moving picture stream.
SOLUTION: A video reproduction application program 201 detects a present load amount of a computer 10. When the computer 10 is not in a high load state, the video reproduction application program 201 performs ordinary decode processing for decoding all coded images. When the computer 10 reaches the high load state, the video reproduction application program 201 skips the execution of decode processing applied to one of odd number slices and even number slices among a plurality of slices each comprising one macro block line included in each decode object image. Then the video reproduction application program 201 generates the image corresponding to each slice whose performance of decode processing is skipped by interpolating a decoded image of the other slice.

摘要： PROBLEM TO BE SOLVED: To provide a file server system which is easily controlled and is capable of flexibly coping with faults of a file server and dynamic addition, etc., of file servers.
SOLUTION: A file server 21 which has accepted a lookup operation request from a client terminal 11 not only refers to its own local file system 214, but also issues inquiries to other file servers 22, etc., implements a directory tree in its own local file system 214 based on inquiry results, and then constructs associated information 302 of directories corresponding to the part. Thus, required environment can be restored on demand, even if the directory tree of the local file system 214 turns into an incomplete state.

摘要： PROBLEM TO BE SOLVED: To provide an information processing unit achieving a proper reduction of a system load related to the decoding of a moving image stream. SOLUTION: A video playback application program 201 inquires an operating system 200 of the system load. If the system load is in a low load state below a preset level, the entire decoding processing (normal decoding processing) including deblocking filter processing is executed. Meanwhile, if the system load is in a high load state higher than, or including, the preset level, a video playback application program 201 executes a special decoding processing omitting the deblocking filter processing of a color difference signal in the deblocking filter processing, and thereby the system load related to the decoding of the moving image stream is reduced.

摘要： PROBLEM TO BE SOLVED: To provide an information processing apparatus capable of properly reducing a system load imposed on decoding a moving picture stream. SOLUTION: A video reproduction application program 201 monitors a size of a window of its own information processing apparatus depending on a notice from an OS 200 and executes all decode processing (ordinary decode processing) including de-blocking filter processing if the size is a full size. On the other hand, if the size is reduced to be, e.g. 60% or below, the video reproduction application program 201 executes special decode processing wherein at least part of the de-blocking filter processing is omitted or simplified depending on a reduced state of the size so as to relieve the system load even a little.

SOLUTION: A video reproduction application program 201 detects a present load amount of a computer 10. When the computer 10 is not in a high load state, the video reproduction application program 201 carries out all decode processing (ordinary decode processing) including de-blocking filter processing. When the computer 10 reaches the high load state, the video reproduction application program 201 performs particular decode processing for omitting performance of the de-blocking filter processing. Decoding and reproduction of moving picture data can smoothly and consecutively be performed without incurring a defect of a frame drop and extremely slowed-down object motions by omitting the performance of the de-blocking filter processing.

摘要： PROBLEM TO BE SOLVED: To provide an information processing apparatus capable of smoothly performing decoding of a moving picture stream without incurring remarkable image quality deterioration.
SOLUTION: A video reproduction application program 201 detects a present load amount of a computer 10. When the computer 10 is not in a high load state, the video reproduction application program 201 decodes a moving picture stream in an ordinary procedure. When the computer 10 reaches the high load state, the video reproduction application program 201 detects a block whose predicted error component is smaller than a prescribed value on the basis of a value of an orthogonal transform coefficient (DCT coefficient) included in each block. Then the video reproduction application program 201 skips performance of inverse orthogonal transform processing (inverse DCT processing) with respect to a detected block and performs processing of zeroing a prediction error signal of the detected block.
