摘要： 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.

摘要： 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.

摘要： A data recording/reproducing apparatus comprises a data recording/reproducing component for recording data including audio and/or video data in and reproducing such data from a plurality of non-linearly accessible recording medium, a plurality of input/output processing sections for processing the input data and outputting them to the recording/reproducing component, while processing the data output from the recording/reproducing component and outputting them, a controller for controlling the input/output processing sections so as to make them carry out the processing operations in the allocated respective time slots and outputting time slot signals with a fixed cycle period to the respective input/output processing sections, the controller being so adapted that, when there is an idle input/output processing section out of the plurality of input/output processing sections, it outputs the time slot signals to be output to the idle input/output processing section to the remaining input/output processing section. 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.

摘要： The endless recording which enables partial saving of recording contents and facilitates editing or management is to be achieved. To this end, if recording has been made for a pre-set time, such as one hour, a new region is secured to continue the recording, at the same time as a region carrying the oldest recorded contents is sequentially evacuated in an amount equal to the newly secured region. The partial saving region (00:10:00:00 to 00:20:00:00) is not to be evacuated.

摘要： 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 20 converts image signals at a rate of 90 frames per second from a camera device 10 into parallel signals to output image signals of the usual rate of 30 frames per second. A video server 30 records the image signals from the CCU 20 on a RAID 32. If a pre-set scene is to be reproduced, the image signals are read out from the RAID 32 in the order of the original image signals to output the read-out image signals to outside.
