Abstract

Embodiments of the invention include a method that comprises recording broadcasted television content and determining if one or more segments of the content is corrupted. The method can also present a notification if the content is corrupted, where the notification can include indicia such as a pop-up window, an icon or symbol in a program guide screen or program recorded content screen, and/or an indicator on the DVR unit. The method can also acquire uncorrupted content to replace one or more segments of the corrupted content.

Claims

1. A method comprising:

recording content that when presented represents a television show;

determining that one or more segments of the content is corrupted;

presenting a notification that the content is corrupted, wherein the notification includes presenting indicia indicating that the content is corrupted, and

acquiring an uncorrupted content for use in replacing the one or more segments of corrupted content; and

replacing the one or more segments of corrupted content with the uncorrupted content.

2. The method of claim 1, wherein the acquiring the uncorrupted content includes requesting, over a network, the uncorrupted content from a web service.

3. The method of claim 1, wherein the acquiring the uncorrupted content includes,

determining, based on analysis of a program guide, that the content will be rebroadcast;

and

recording, during the rebroadcast, the uncorrupted content.

4. The method of claim 1, wherein the determining that one or more segments of the content is corrupted includes analyzing the content using one or more analysis methods selected from the group consisting of reduced signal strength analysis, mismatch checksum analysis, silent and white noise detection analysis, user demarcation analysis, digital block detection analysis, and service provider notification analysis.

5. The method of claim 1, wherein indicia includes one or more selected from the group consisting of a pop-up window, an icon or symbol in a program guide screen or program recorded content screen, and an indicator on die DVR unit.

6. The method of claim 1, wherein the determining that one or more segments of the content is corrupted includes detecting user demarcations, wherein the user demarcations identify the one or more segments.

7. A content delivery system comprising:

a DVR unit configured to record content to a medium and to transmit communications, the communications including information about corruption of the content;

a media replacement service configured to receive the communications including information about corruption in the content and to provide the DVR unit with corrected content;

a content service provider to transmit the content to the DVR unit and to notify the DVR unit about corruption to the recorded content.

8. The content delivery system of claim 7, wherein the DVR unit further comprises:

a user notification unit configured to present notifications about the corruption in the content, and wherein the notifications include a pop-up screen indicating that the content is corrupted, an icon depicting corruption, an indicator on the DVR unit, and a modification to the detailed recording describing the corruption and potentially the affected times.

9. The content delivery system of claim 7, wherein the DVR unit further comprises:

a media corruption correction unit configured to schedule recording of a rebroadcast of the content.

10. The content delivery system of claim 7, wherein the content service provider is further configured to detect corruption in recorded media by analysis of weather data and to notify the DVR unit about the corruption.

11. An apparatus comprising:

a content storage unit configured to record content that when presented represents a television show;

a media corruption detection unit configured to determine that one or more segments of the content is corrupted;

a user notification unit configured to present a notification that the content is corrupted, wherein notification includes indicia that indicates that the content is corrupted; and

a media corruption correction unit configured to acquire an uncorrupted content to replace the one or more segments of corrupted content.

12. The apparatus of claim 11, wherein the media corruption correction unit is further configured to acquire the uncorrupted content, via a request over a network, from a web service.

13. The apparatus of claim 11, wherein the media corruption correction unit is further configured to acquire the uncorrupted content by a

determination that the content will be rebroadcast and

recordation of the uncorrupted content during the rebroadcast.

14. The apparatus of claim 11, wherein the media corruption detection unit is further configured to determine that one or more segments of the content is corrupted by analysis of the content using one or more analysis methods selected from the group consisting of reduced signal strength analysis, mismatch checksum analysis, silent and white noise detection analysis, user demarcation analysis, digital block detection analysis, and service provider notification analysis.

15. The apparatus of claim 11, wherein the user notification unit is further configured to present indicia that includes one or more selected from the group consisting of a pop-up window, an icon or symbol in a program guide screen or program recorded content screen, and an indicator on the DVR unit.

16. The apparatus of claim 11, wherein the media corruption detection unit is further configured to determine that one or more segments of the content is corrupted by detection of user demarcations, wherein the user demarcations identify the one or more segments.

17. A tangible machine-readable medium including instructions that when executed by a machine cause the machine to perform operations comprising:

recording content including data that when presented represents a television show;

determining that one or more segments of the content is corrupted;

presenting a notification that the content is corrupted, wherein the notifying includes presenting indicia indicating that the content is corrupted, and

acquiring an uncorrupted content for use in replacing the one or more segments of corrupted content; and

replacing the one or more segments of corrupted content with the uncorrupted content.

18. The machine-readable medium of claim 17, wherein the determining that one or more segments of the content is corrupted includes analyzing the content using one or more analysis methods selected from the group consisting of reduced signal strength analysis, mismatch checksum analysis, silent and white noise detection analysis, user demarcation analysis, digital block detection analysis, and service provider notification analysis.

19. The machine-readable medium of claim 17, wherein indicia includes one or more selected from the group consisting of a pop-up window, an icon or symbol in a program guide screen or program recorded content screen, and an indicator on the DVR unit.

20. The machine-readable medium of claim 17, wherein the determining that one or more segments of the content is corrupted includes detecting user demarcations, wherein the user demarcations identify the one or more segments.
