Abstract
A method and apparatus for processing data read from a DVD media containing stored data is described. The apparatus includes a DVD media reader for reading data and error information stored on a DVD media, an error processor for determining the number of errors in the read data, and a display means for displaying the number of errors. The method includes reading actual data from a DVD media, computing a first correction code for the actual data, reading a second correction code from the DVD media, the second correction code pertaining directly to said stored data, and comparing the first and second correction codes to determine whether said actual data needs to be corrected. The method further includes determining whether the number of errors in the actual data exceeds the maximum number of errors that can be corrected, correcting the actual data if possible, counting the number of errors that are corrected, and indicating if errors in a given row or column cannot be corrected.
