Patent ID: 8762397

Claim:
A method comprising: obtaining, by a system including a processor, a group of content streams of a multimedia work; filtering out, by the system, redundant content in the group of content streams to generate a filtered group of content streams prior to performing a coarse feature analysis; performing, by the system, the coarse feature analysis of the filtered group of content streams at a multiple frame level; identifying, by the system, a subset of the filtered group of content streams having a potential occurrence of an objectionable feature according to the coarse feature analysis; responsive to the identifying of the subset of the filtered group of content streams, performing, by the system, a feature specific analysis on the subset at a frame by frame level; identifying, by the system, an occurrence of the objectionable feature according to the feature specific analysis; retrieving, by the system, additional information associated with the multimedia work based on metadata of the group of content streams; and correlating, by the system, the occurrence of the objectionable feature with the additional information to generate a weighted content description of the multimedia work.
