Abstract

An apparatus for processing digital data receives a first set of digital data that has a plurality of subsets of digital data. The apparatus contains memory to store the digital data. The apparatus receives a second set of digital data that has a first set of displayable data, a linkage reference and a second set of displayable data. The second set of digital data is used to indicate a presence of the linkage reference. The linkage reference is associated with one of the subsets of digital data. The apparatus determines whether there is error in the subsets of digital data. The apparatus causes a display device to display the second set of displayable data in a first way to indicate that the first linkage reference is active if there is no error and a second way to indicate that the first linkage reference is not active when there is error.

Claims

1. A method for processing data of an apparatus, the method comprising:

receiving a first set of digital data comprising a plurality of subsets of digital data and storing the first set of digital data inside the apparatus;

receiving a second set of digital data comprising a first set of displayable data, a first linkage reference and a second set of displayable data for indicating a presence of the first linkage reference, the first linkage reference allowing easy access to at least one of the subsets of digital data;

determining whether there is error in the at least one of the subsets of digital data;

if there is no error, causing a display device to display the second set of displayable data in a first way to indicate that the at least one of the subsets of digital data is accessible via the first linkage reference; and

if there is error, causing the display device to display the second set of displayable data in a second way to indicate that the at least one of the subsets of digital data is not accessible via the first linkage reference.

2. The method of claim 1 wherein the first set of displayable data is displayed in a way that is substantially the same as the second way.

3. The method of claim 1 wherein the first linkage reference is separated from the first or the second sets of displayable data by a third set of digital data.

4. The method of claim 1 wherein the second set of digital data comprises a second linkage reference, the second linkage reference being associated with data in a remote location external to the apparatus.

5. The method of claim 4 wherein the second set of digital data comprises a third set of displayable data for indicating a presence of the second linkage reference.

6. The method of claim 5 wherein the second and the third sets of displayable data are displayed in different ways.

7. The method of claim 1 comprising a step of correcting the at least one of the subsets if it contains error by accessing information in a remote location.

8. A method for processing data of an apparatus, the method comprising:

receiving a first set of digital data comprising a plurality of subsets of digital data and storing the first set of digital data inside the apparatus;

receiving a second set of digital data comprising a first set of displayable data, a first linkage reference and a second set of displayable data for indicating a presence of the first linkage reference, the first linkage reference allowing easy access to at least one of the subsets of digital data;

determining whether there is error in the at least one of the subsets of digital data;

if there is no error, causing a display device to display the second set of displayable data in a first way to indicate that the at least one of the subsets of digital data is accessible via the first linkage reference; and

if there is error, causing the display device to display the second set of displayable data in a second way to indicate that the at least one of the subsets of digital data is not accessible via the first linkage reference;

wherein the plurality of subsets each is associated with an identification, wherein the determining includes identifying the identifications that are associated with the subsets that contain errors, and wherein the causing step for the case of error in the at least one of the subsets comprises;

scanning the second set of digital data for the first linkage reference;

determining whether the first linkage reference is associated with one of the identified identifications, and

causing the display device to display the second set of displayable data in the second way if the first linkage reference is associated with one of the identified identifications.

9. The method of claim 8 wherein the first set of displayable data is displayed in a way that is substantially the same as the second way.

10. The method of claim 8 wherein the second set of digital data comprises a code for indicating a presence of the first linkage reference, and the scanning comprises searching for the code.

11. The method of claim 8 wherein the second set of digital data comprises a second linkage reference, the second linkage reference being associated with information in a remote location external to the apparatus.

12. The method of claim 10 wherein the second set of digital data comprises a third set of displayable data for indicating a presence of the second linkage reference.

13. The method of claim 12 wherein the second and the third sets of displayable data are displayed in different ways.

14. A method for processing data of an apparatus, the method comprising:

receiving a first set of digital data comprising a plurality of subsets of digital data and storing the first set of digital data inside the apparatus;

receiving a second set of digital data comprising a first set of displayable data, a first linkage reference and a second set of displayable data for indicating a presence of the first linkage reference, the first linkage reference allowing easy access to at least one of the subsets of digital data;

determining whether there is error in the at least one of the subsets of digital data;

if there is no error, causing a display device to display the second set of displayable data in a first way to indicate that the at least one of the subsets of digital data is accessible via the first linkage reference;

if there is error, causing the display device to display the second set of displayable data in a second way to indicate that the at least one of the subsets of digital data is not accessible via the first linkage reference; and

correcting the at least one of the subsets if it contains error by accessing information in a remote location;

wherein the plurality of subsets each is associated with an identification, wherein the determining includes identifying the identifications that are associated with the subsets that contain errors, the method further comprising, after the correcting the at least one of the subsets;

scanning the second set of digital data for the first linkage reference;

determining whether the first linkage reference is associated with the corrected subset; and

causing the display device to display the second set of displayable data in the first way if the first linkage reference is associated with the corrected subset.

15. The method of claim 14 wherein the second set of digital data comprises a code for indicating a presence of the first linkage reference, and the scanning comprises searching for the code.

16. The method of claim 14 wherein the second set of digital data comprises a second linkage reference, the second linkage reference being associated with information in a remote location external to the apparatus.

17. The method of claim 16 wherein the second set of digital data comprises a third set of displayable data for indicating a presence of the second linkage reference.

18. The method of claim 17 wherein the second and the third sets of displayable data are displayed in different ways.
