RECORDING MEDIUM FOR EDITING RECORDING CONTENT WHILE COMPATIBILITY WITH CONVENTIONAL FORMAT IS MAINTAINED, REPRODUCER AND RECORDING DEVICE

摘要

PROBLEM TO BE SOLVED: To avoid occurrence of a phenomenon where a part except for a common item with an old format in the latest format corresponding to a high frame rate is rewritten later.SOLUTION: Index.bdmv is recorded in a BDMV directory in a rewritable recording medium. Index.bdmv includes an editability_flag, and an extended_editability_flag. The recording medium is treated as a non-editable medium by setting the editability_flag to be "off". Even if the editability_flag shows "off" when the recording medium is loaded on a non-legacy device corresponding to recording and editing, the extended_editability_flag specifies effect that the recording medium is treated as the editable medium and editing to the stream file becomes possible.
