Abstract:
A data reproducing apparatus for reproducing video data recorded on a plurality of non-linear access recording mediums such that neighboring image pixels are recorded on different recording mediums, said apparatus comprising:a plurality of RAIDs for reproducing said video data; each RAID having a plurality of said non-linear access recording mediums, an error correction circuit, and a conceal pixel setting circuit; said error correction circuit correcting erroneous pixels in the reproduced video data using previously recorded parity data when said erroneous pixels are reproduced from a single nonlinear-access recording medium; said conceal pixel setting circuit substituting a first predetermined signal for erroneous pixels in the reproduced video data when said erroneous pixels are reproduced from more than one nonlinear-access recording medium; a plurality of output processors for output processing video data reproduced from said plurality of non-linear access recording mediums; each output processor having a function quit detection circuit and a conceal processing circuit; said function quit detection circuit detecting when one of said RAIDs is not functioning and substituting a second predetermined signal for the reproduced video data from the non-functioning RAID; and said conceal processing circuit detecting said first and second predetermined signals and mending the reproduced video data by interpolating for the pixels substituted for by said first and second predetermined signals using neighboring pixels.
