  • DVD navigation systems and computer-implemented methods with check functions
    Patent number: 8422865
    Abstract: A DVD navigation system comprises a plurality of navigation modules and a utility. Each navigation module comprises a check function determining data correctness of tables corresponding to the respective navigation modules. Each navigation module generates a read table request. The utility receives the read table request, reads at least one table identified by the read table request from at least one IFO file in a file system, and checks data correctness of the table by using the check function. If the data of the table is incorrect, the utility reads the table from at least one backup file of the IFO file in the file system, and transmits the data to the navigation module for decoding.
