Abstract

A disclosed method for facilitating automated and user-specific filtering of multimedia content includes a backend server receiving a content identifier from a user'"'"'s multimedia handling device (MHD), e.g., a set top box. The content identifier indicates of a program of multimedia content (PMC) requested or otherwise desired by a user. The disclosed method includes identifying or otherwise locating an index file associated with the requested PMC. The index file includes data that indicates portions of the PMC containing potentially objectionable content. Content filtering (CF) settings associated with the user are retrieved or otherwise accessed. The CF settings define at least one type of content that is objectionable to the user. The CF settings are applied to the index file to identify a portion of the PMC containing content objectionable to the user. Content location information that indicates the identified portion of the PMC is then sent to the MHD.

Claims

1. A method for facilitating automated user-specific filtering of multimedia content, comprising:

receiving a content identifier indicative of a program of multimedia content (PMC) desired by a user;

identifying an index file associated with the identified PMC, wherein the index file includes information indicative of portions of the PMC containing potentially objectionable content;

retrieving content filtering (CF) settings associated with the user, the CF settings defining at least one type of content objectionable to the user;

applying the CF settings to the index file to identify a portion of the PMC containing content objectionable to the user; and

sending content location information, indicative of the identified portion of the PMC, to a multimedia handling device.

2. The method of claim 1, wherein the content location information comprises chronological content location information indicative of at least one of a beginning time and an ending time of the identified portion.

3. The method of claim 1, wherein the content location information comprises frame identification information indicative of at least one of a beginning frame and an ending frame of the identified portion.

4. The method of claim 1, further comprising receiving the index file from a provider of the PMC.

5. The method of claim 1, further comprising generating the index file from the PMC by performing at least one of audio and video analysis of the PMC.

6. The method of claim 1, wherein the at least one type of content objectionable to the user is a word type specifying at least one objectionable word.

7. A multimedia handling device (MHD) including a processor and storage media accessible to the processor, the MHD comprising:

a network interface to receive multimedia content from a content delivery server via an access network;

a decoder configured to process the multimedia content and to provide decoded content to a multimedia display device;

a remote control interface to process remote control signals from a remote control;

processor executable instructions, embedded in the storage media including instructions to;

respond to detecting a remote control signal selecting a multimedia content object by sending a content identifier to a server via the access network; and

respond to receiving content location information indicative of a selected portion of the multimedia content object by modifying the multimedia content object to prevent at least one of an audio component and a video component of the selected portion from playing on the multimedia display device.

8. The device of claim 7, wherein preventing comprises presenting alternative content in place of the selected portion.

9. The device of claim 8, wherein the alternative content conveys the occurrence of content filtering to a viewer of the multimedia content object.

10. The device of claim 7, wherein preventing comprises suppressing at least one of the audio component and the video component from playing.

11. The device of claim 7, wherein the instructions further comprise instructions to respond to a predetermined sequence of at least one remote control signal by displaying a filter settings interface on the display device wherein the filter setting interface is enabled to respond to filter setting remote control signals by creating or modifying filter setting data defining objectionable content.

12. A content filtering service offered to a user in conjunction with a multimedia content distribution service, the content filtering service comprising:

enabling the user to create filter settings defining at least one type of multimedia content objectionable to the user;

enabling the user to request a program of multimedia content (PMC);

providing content location information to customer premise equipment (CPE) of the user, wherein the content location information is indicative of a portion of the PMC containing content objectionable to the user;

enabling the CPE to modify the PMC based at least in part on the content location information, wherein the modified PMC suppresses at least one of an audio component and a video component of the portion of the PMC indicated by the content location information.

13. The service of claim 12, wherein the at least one type of objectionable content comprises a type selected from the group consisting of an objectionable word type and an objectionable scene type, wherein the objectionable word type specifies at least one objectionable word and the objectionable scene type specifies at least one objectionable visual element.

14. The service of claim 12, wherein providing the content location information includes querying an index file corresponding to the PMC using the filter settings, wherein the index file contains information indicative of portions of the PMC containing potentially objectionable content.

15. The service of claim 12, wherein the content location information is indicative of at least one of a beginning time and an ending time of the portion of the PMC containing objectionable content.

16. The service of claim 12, wherein the content location information is indicative of at least one of a beginning frame and an ending frame of the portion of the PMC containing objectionable content.

17. A method of processing multimedia content, comprising:

receiving a stream corresponding to a predetermined program of multimedia content (PMC);

receiving content location information indicative of a portion of the PMC containing objectionable content; and

decoding the stream to produce decoded content including an audio component and a video component and modifying the decoded content by modifying at least one of the audio component and the video component of the objectionable portion of the PMC.

18. The method of claim 17, wherein decoding comprises decoding according to a decoding algorithm selected from the group consisting of MPEG-2, MPEG-4, WMV 7, WMV 8, and WMV 9.

19. The method of claim 17, further comprising:

sending a content identifier indicative of the PMC; and

storing content filter settings indicative of at least one type of objectionable content.

20. The method of claim 17, wherein modifying at least one of the audio component and the video component comprises suppressing at least one of the audio component and the video component.

21. The method of claim 17, wherein modifying at least one of the audio component and the video component comprises providing at least one an alternative audio component and an alternative video component.
