There is provided an image reproducing apparatus and an image reproducing method which allow reproducing speed to be shifted instantly when a change of the reproducing speed is requested in a multi-channel AV (Audio Visual) server. When a request to reproduce an image is made, the image reproducing apparatus reads image data of the part corresponding to the requested reproducing speed out of the HDDs to store in a temporary storage section. Then, an image output I/F reads the image data stored in the temporary storage section and structures a reproduced image by using the image data. In this case, a controller section controls a pattern in reading the divisional data by the image output I/F and structures a reproduced image by means of various reproducing speeds by this reading pattern.

Image reproducing apparatus and image reproducing method

A data recording and reproducing apparatus capable of correctly recording or reproducing data groups by linking divided data within a hard disk is provided. When a group of data such as video and music data are recorded into a hard disk to which random access is possible, file controlling information for indicating a link between the plurality of groups of data is produced from the time code of the groups of data in a time-ordered fashion. Thus-produced file controlling information is then stored in a SRAM of an operation controlling section. When the reproduction position is indicated by the time code, this position is converted into a relative position from the initial position of the file by using the file controlling information. Based on the relative position from the initial position of the file, the data is read out from the hard disk.

Data recording and reproducing apparatus, and method for recording and reproducing data without time code discontinuities

A data recording and reproducing apparatus capable of easily obtaining information which has few dropout and is necessary for variable speed reproduction at the time of variable speed reproduction. An image group dividing unit divides input image data into a plurality of image groups on a unit image basis, thereby forming plural divided data. After the formed divided data is temporarily stored into an image data temporary storing unit, the divided data is outputted as image data which is a data stream of the divided data in a predetermined image unit to a disk array apparatus via an HDD output interface unit. Each disk array apparatus records the divided data into HDDs so as to periodically change the relation between the HDDs and the groups of data to be recorded to the HDDs in a predetermined pattern.

Data recording and reproducing apparatus and method

In a video data reproducing apparatus adapted for reading out data including video data stored on plural non-linear accessible recording media by time slots allocated thereto to output those data, when the video data which has been read out from the recording medium is outputted to the external as n (n>1) times speed video data, a processing is carried out by a reproduction picture dividing section such that when n is integer, output image 1 frame is divided by n, while when n is not integer, output image 1 frame is divided by m (m is integral part of n: n&equals;m. . . . ), and such a processing is carried out by a reproduction image generating section to allocate n frames or m frames of the video data which has been read out from the recording medium to the output image 1 frame divided by n or divided by m to generate reproduction image.

Data reproduction using time slot allocation

A recording medium is logically divided to form a cluster. Each cluster records AV (Audio Visual) data. A reference number indicates the number of files which reference AV data. A free space byte map having the reference number is used for determining whether to enable or disable deletion of AV data on a cluster basis. That is, a cluster having the reference number is released as a free area, thus facilitating management of a file and realizing effective use of a recording medium.

With such an arrangement, more time slots are allocated to the busy input/output processing sections, which can therefore output an increased number of data sheets per unit time for a high speed data reproducing operation to improve the operability of the apparatus.

Video data recording and reproduction using time slot allocation

An image from a camera is to be recorded and reversion is to be made to an image of an optional scene to reproduce an image of such scene. To this end, a CPU converts image signals at a rate of 90 frames per second from a camera device into parallel signals to output image signals of the usual rate of 30 frames per second. A video server records the image signals from the CCU on a RAID If a pre-set scene is to be reproduced, the image signals are read out from the RAID in the order of the original image signals to output the read-out image signals to outside.
