Claim:
A method for implementing parental control on a scene-by-scene basis on a digital device comprising: receiving incoming digital content from a digital data stream intended as a scene of a program; decoding the scene during playback, decoding the scene of the program includes determining on a scene-by-scene basis if the scene of the program includes objectionable content based on closed captioning information included with the content; and blocking a display of the scene of the program if, during the decoding, the scene of the program is determined to include objectionable content based on analysis of the closed captioning information, wherein the analysis of the closed captioning information includes obtaining hints that the scene of the program includes objectionable content, the hints being descriptions of noises suggesting sexual or violent situations in the scene of the program, wherein the analysis of the closed captioning information includes comparing the closed captioning information with prior established parental control limits, the prior established parental control limits including at least one of an Age-based parental control limit and a parental control parameter tag, wherein comparing the closed captioning information includes determining whether the closed captioning information includes an Age-based rating assigned to the scene of the program, in response to the closed captioning information including the Age-based rating assigned to the scene of the program, determining whether the Age-based rating assigned to the scene of the program exceeds the Age-based parental control limit, in response to the closed captioning information not including the Age-based rating assigned to the scene of the program, determining whether the closed captioning information includes a tag information assigned to the scene of the program, the tag information identifying at least one of a plurality of categories of objectionable content present in the scene of the program and at least one of a plurality of sub-categories of objectionable content present in the scene of the program, and in response to the closed captioning information including the tag information assigned to the scene of the program, determining whether the tag information assigned to the scene of the program corresponds to the parental control parameter tag.
