Abstract
A number of different subroutines or algorithms are provided for locating lost video data, reconstructing navigation data, and creating new navigation files or the like so that the DVD may be made readable by an ordinary DVD player. The present invention provides algorithms to recover video data for each of a number of different DVD formats, so that video data may be recovered regardless of which format DVD was being used at the time (e.g., DVD+RW, DVD+R, DVD-RW, DVD-R, or the like). In addition, the present invention provides a number of other algorithms that be used by one or more of the different recovery algorithms, to recover various aspects of data from a disc. The combination of these algorithms provides a complete package of data recovery techniques that allows for video data to be recovered in the event of a power loss or other interruption, and in most instances, creates recordable DVD which may be subsequently read by other DVD players and the like.
