Abstract: I/O processing sections for inputting and outputting AV data between themselves and the outside are connected to RAIDS through a network. Each I/O processing section includes an input processing section for distributing divided AV data inputted from the outside to two or more RAIDS and generating error-correcting codes of AV data for transferring it to at least one RAID, and an output processing section for correcting the AV data transferred from the RAID by using the error-correcting codes of the AV data transferred from the RAID to outputting the corrected data to the outside. With the function of correcting error in the network provided upstream, not only in the case of breakdown of the hard disk of RAIDS, but also in the case of breakdown of I/O processing upstream, outputting AV data without loss in reproduction can be performed, AV server is prevented from becoming larger in scale, and a load imposed on the network is prevented from increasing.

Abstract: Disclosed is an apparatus for processing images with which, when bit streams of images subjected to the MPEG coding in the form of open GOP are joined to each other, image quality is prevented from deteriorating at the joint between the bit streams. In the apparatus for processing images, when a bit stream Y is inserted in a bit stream X, before-I-picture B-pictures (B-pictures appearing before an I-picture is displayed) which are part of images forming first one of GOP's in the bit stream Y are deleted. Temporal references of the remaining images forming the first GOP are then changed. The before-I-picture B-pictures, which are otherwise predicted by using one of images forming the last GOP of the bit stream X, are not longer displayed.

Abstract: Audio signals that correspond with still images are recorded in an electronic still camera on the same magnetic disc as the visual images. By time-base compressing the audio signal and dividing each record track into a number of segments, ten seconds of audio can be recorded for each image without requiring a large processor memory. Identification codes are added to the time-base compressed audio to permit multiple audio tracks to be associated with a recorded image and to record audio signals of time length less than the allotted duration, so that a number of images can be recorded in rapid succession without waiting for each of the successive allotted audio time periods to expire.
