System for parental control in video programs based on multimedia content information

摘要

A parental control system provides the ability to automatically filter a multimedia program content in real time based on stock and user specified criteria. The criteria are used to teach a learning module in the system what types of video program segments are to be considered sensitive or objectionable so that the module's understanding of what is sensitive and what is not can be applied to other video programs to provide real-time filtering. The multimedia program is broken down into audio, video, and transcript components so that sound effects, visual components and objects, and language can all be analyzed collectively to make a determination of whether offending material is being passed along in the multimedia program. The user has the option of training the system for any type of objectionable material, not just sex and violence.

主权项

1. A method performed by a device to filter objectionable material, from a multimedia program including plural segments, on a segment-by-segment basis responsive to a filter criteria, comprising:
providing a learning module to generate the filter criteria learned based on user instructions by examples of objectionable content; splitting the multimedia program into plural components; extracting audio, video, and transcript features from segments within the plural components; processing each segment amongst the segments, according to the learned filter criteria generated by the learning module and the extracted features, and generating a numeric ranking corresponding to the filter criteria learned based on the user instructions by examples of objectionable content and applied to the segment; and when the respective numeric ranking for the segment exceeds a threshold, processing the segment to thereby eliminate material corresponding to the learned filter criteria.
