AI Technical Summary

Benefits of technology

This patented describes methods and systems that use Optic Disc Libraries (OBLs) to restore digital images from their original storage format onto another media like CD). These techniques help prevent image quality issues caused by physical damage during copying processes such as scratches, bumps, cracks, etc., while also allowing users accessorized content without being able to see any changes made over time due to these defects. Overall, this approach helps preserve copyrighted documents' worthiness and protect them against unauthorised modifications.

Problems solved by technology

This patented technical solution involves storing digital videos (DVDs) electronics libraries without being influenced by these factors like dirtiness caused during their use over an extended period of time due to environmental conditions such as temperature changes and humidity fluctuations. These issues can cause errors when accessing certain parts of the image content through playback devices. Current solutions involve manually correcting erroneously recorded areas based upon visual inspections provided by experts who may lack expertise or experience.

Abstract

The invention discloses an electronic video file repairing method and system based on an optical disc jukebox, and relates to the field of file repairing, and the method comprises the steps: determining a data damaged point of a target optical disc according to reflection energy; performing feature map extraction on the middle damaged data point sequence, the left side normal data point sequence and the right side normal data point sequence to obtain corresponding feature maps; calculating a normal frame query vector, a damaged frame key vector and a damaged frame reduction value vector according to a preset projection matrix; updating a damaged frame reduction value vector by adopting the normal frame query vector and the damaged frame key vector; on the basis of a self-addition and self-attention mechanism, the damaged frame reduction value update vectors obtained after updating of the left side and the right side are fused, and a fusion feature map is obtained; and repairing the electronic video file of the target optical disk according to the fused feature map. According to the method, lost or damaged data can be effectively and quickly repaired, and the authenticity of archive data is ensured.
