Moving image management method and apparatus

摘要

For multiple moving-image recorded on a storage medium, one piece of meta-data or each of multiple pieces of meta-data recorded for a part or all of the moving-image is managed by meta-data indices. A meta-data index keeps invalidity information indicating whether a piece of meta-data is going to be invalid and validity information indicating validity of the current piece of meta-data in the same form, when operations such as editing and processing are performed on a part or all of a moving-image that is an object of a piece of meta-data. When cutting-out occurs on a section of a moving-image that is an object of a piece of meta-data and the piece of meta-data cannot be recalculated, the invalidity information is copied to the validity information. In this manner, a meta-data added to the moving-image can be adapted and be used after the moving-image is edited.
