Abstract

Embodiments of the invention include a method that comprises receiving a request to record television content on a specified channel for a specified period of time. The method can also include tuning to the specified channel at the specified time, and recording the specified content. The method can also include determining that one or more segments of the television content is corrupted. The method can also include presenting a notification indicating that some of the television content is corrupted, retuning to the specified channel made by the request, and acquiring uncorrupted television content for use in replacing the one or more segments of corrupted television content.

Claims

1. A method comprising:

receiving a request to record television content on a specified channel for a specified period of time;

tuning to the specified channel at the specified time;

recording some of the television content;

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

presenting a notification indicating that some of the television content is corrupted;

retuning to the specified channel and recording more of the television content; and

acquiring uncorrupted content for use in replacing the one or more segments of corrupted television content.

2. The method of claim 1, wherein the retuning to the specified channel includes transmitting a signal including a key sequence and the specified channel.

3. The method of claim 1, wherein the receiving a request to record television content on a specified channel for a specified period of time includes receiving a user selection of the television content from a menu of television content available for recording.

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 reduced signal strength analysis, stagnant pixel analysis, silent and white noise detection analysis, mismatch checksum analysis, user demarcation analysis, and digital block detection 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 in a program guide screen, an icon in a recorded content screen, and an indicator on a digital video recorder.

6. The method of claim 1, wherein the acquiring the uncorrupted content includes one or more operations selected from the group consisting of receiving the uncorrupted content via a satellite network and receiving the uncorrupted content from over the internet.

7. The method of claim 1, wherein acquiring includes determining that the television content will be rebroadcast, and recorded during the rebroadcast.

10. The media content delivery system of claim 7, wherein die DVR unit further comprises:

a user notification unit configured to present notifications about the corruption in the first content.

11. The media content delivery system of claim 10, wherein the notifications include one or more selected from the group consisting of a pop-up screen indicating that the content is corrupted, an icon in a recorded content interface, an indicator on die DVR unit, and a message describing the corruption and time.

8. A media content delivery system comprising:

a DVR unit configured to record a first content, to detect corruption in the first content, to transmit wireless signals indicating a key sequence and a channel, and to request a second content to replace the first content;

a media replacement service configured to receive the request for the second content and to provide the second content to the DVR unit;

a satellite dish configured to receive the wireless signals from the DVR unit and to retune to the channel based on the key sequence and the channel, the satellite dish also configured to transmit, to the DVR unit, a third content included in the channel.

9. The media content delivery system of claim 8, wherein the DVR unit is configured to detect the corruption in the first content by one or more analysis methods selected from the group consisting of reduced signal strength analysis, stagnant pixel analysis, silent and white noise detection analysis, mismatch checksum analysis, user demarcation analysis, and digital block detection analysis.

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

a media corruption correction unit configured to download a corrected version of the corrupted content from the web enabled media repository.

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

a media corruption correction unit configured to create metadata to indicate when to present the second content.

14. An apparatus comprising:

a digital video recorder (DVR) unit configured to receive a request to record television content on a specified channel for a specified period of time;

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

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

a media corruption correction unit configured to retune to the specified channel made by the request

15. The apparatus of claim 14, 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, stagnant pixel analysis, silent and white noise detection analysis, mismatch checksum analysis, user demarcation analysis, and digital block detection analysis.

16. The apparatus of claim 14, wherein the user notification unit if further configured to present indicia that includes one of more selected from the group consisting of a pop-up window, an icon in a program guide screen, an icon in a recorded content screen, and an indicator on a digital video recorder.

17. The apparatus of claim 14, wherein the media corruption correction unit is further configured to acquire the uncorrupted content from one or more operations selected from the group consisting of receiving the uncorrupted content via a satellite network, receiving the uncorrupted content over the internet, receiving die uncorrupted content via telephony, and receiving the uncorrupted content over a network, from a web service.

18. A machine-readable medium including instructions that when executed by a machine cause die machine to perform operations comprising:

receiving a request to record television content on a specified channel for a specified period of time;

tuning to the specified channel at the specified time;

recording the specified content;

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

presenting a notification that the content is corrupted;

retuning to the specified channel made by the request, the retuning including transmitting a signal indicating die specified channel and a key sequence; and

acquiring uncorrupted content for use in replacing the one or more segments of corrupted television content.

19. The machine readable medium of claim 19, wherein the receiving a request to record television content on a specified channel for a specified period of time includes receiving a user selection of the television content from a menu of television content available for recording.

20. The machine readable medium of claim 19, 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, stagnant pixel analysis, silent and white noise detection analysis, mismatch checksum analysis, user demarcation analysis, and digital block detection analysis.
