Content filtering for a digital audio signal

1. A method, comprising:

receiving an original digital audio block associated with a television signal and one of a plurality of content providers;

translating the original digital audio block into a set of words;

determining that at least one of the words is included in a set of prohibited words, wherein determining is based on the one of a plurality of content providers, and wherein each of plurality of content providers is associated with a respective set of prohibited words; and

facilitating removal of the prohibited word from the original digital audio block, wherein said facilitating includes, replacing, by a processor, a portion of the original digital audio block with a plurality of consecutive replacement portions, each replacement portion having a pre-defined duration and the number of replacement portions being based on the duration value, to create a modified digital audio block.

2. The method of claim 1 , wherein the television signal is a high definition television signal and the original digital audio block is received from an audio decoder.

3. The method of claim 1 , wherein said translating includes processing the original digital audio block to generate text and said determining includes comparing the text to the set of prohibited words.

4. The method of claim 1 , further comprising:

providing the modified digital audio block to an audio device.

5. The method of claim 4 , wherein the audio device is one of: (i) an audio renderer, (ii) an audio re-encoder, (iii) a sound card, (iv) an audio receiver, or (v) a television device.

6. The method of claim 1 , further comprising:

receiving close-captioned text information;

comparing the close-captioned text information with the set of prohibited words; and

replacing characters in the close-captioned text information with replacement characters.

7. The method of claim 6 , wherein the replacement characters comprise one of:

(i) a pre-defined character, (ii) deleted characters, or (iii) a replacement word.

8. The method of claim 1 , further comprising:

receiving from a user an indication associated with a prohibited word.

9. The method of claim 8 , wherein the indication is associated with at least one of: (i) a content category, (ii) a content level, (iii) a graphical user interface, or (iv) a remote device.

10. The method of claim 1 , further comprising:

converting a received analog audio signal into the original digital audio block.

11. The method of claim 1 , wherein the list of prohibited words is associated with at least one of: (i) a viewer, (ii) a content provider, (iii) a time, or (iv) a rating.

12. A non-transitory computer-readable storage device storing instructions adapted to be executed by a processor to perform a method to facilitate content filtering for a digital audio signal, said method comprising:

receiving by the processor an original digital audio block associated with a television signal and one of a plurality of content providers;

translating, by the processor, the original digital audio block into a set of words;

determining, by the processor that at least one of the words is included in a set of prohibited words, wherein the determining is based on the one of a plurality of content providers, and wherein each of plurality of content providers is associated with a respective set of prohibited words; and

automatically facilitating removal of the prohibited word from the original digital audio block, by the processor, wherein said facilitating includes replacing a portion of the original digital audio block with a plurality of consecutive replacement portions, each replacement portion having a pre-defined duration and the number of replacement portions being based on the duration value, to create a modified digital audio block.

13. The article of claim 12 , wherein the television signal is a high definition television signal and the original digital audio block is received from an audio decoder.

14. The article of claim 12 , wherein said translating includes processing the original digital audio block to generate text and said determining includes comparing the text to the set of prohibited words.

15. An apparatus, comprising:

an input line to receive an original digital audio block associated with a television signal and one of a plurality of content providers;

a translating unit to convert the original digital audio block into a set of words; and

a content filter processing unit to (i) determine, by a processor, that at least one of the words is included in a set of prohibited words, wherein the determining is based on the one of a plurality of content providers, and wherein each of plurality of content providers is associated with a respective set of prohibited words and (ii) facilitate removal of the prohibited word from the original digital audio block, wherein said removal includes replacing a portion of the original digital audio block with a plurality of consecutive replacement portions, each replacement portion having a pre-defined duration and the number of replacement portions being based on the duration value, to create a modified digital audio block.

16. The apparatus of claim 15 , further comprising:

an audio decoder to convert a received audio stream into the original digital audio block.

17. The apparatus of claim 15 , further comprising:

an audio device to receive a modified digital audio block including the plurality of consecutive replacement portions.

18. The apparatus of claim 15 , wherein the apparatus is associated with at least one of: (i) a television, (ii) a set-top box, (iii) a personal computer, (iv) a portable device, (v) a wireless device, (vi) a media player, or (vii) a game device.
