Audiovisual Frame Extraction for Parental Control Rating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parental control methods for audiovisual content are inefficient as they rely on rating systems that are subjective and require significant time for parents to evaluate content appropriateness, or they rely on unreliable example content previews.
Innovation Solution
A method that displays multiple frames associated with different watching levels, allowing users to quickly set a watching level by selecting a frame, with the option to play back associated audiovisual segments for detailed evaluation and automatic or manual determination of watching levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parents watch the whole audiovisual content to form an opinion, then the reliability of parental control is improved, but the time required is excessive
Solution Approach 1:
The patent extracts representative frames from the audiovisual content to create a condensed visual summary. Instead of requiring parents to view the entire content, the system extracts key frames that capture the essence and offensiveness of different segments, allowing rapid evaluation while maintaining reliability.
Solution Approach 2:
The system performs preliminary analysis of the audiovisual content by pre-generating multiple frames with associated watching levels before parental review. This preliminary action prepares the content in an easily evaluable format, so parents only need to review the pre-processed frames rather than the entire content.
2Loss of time
If a rating system is used to indicate content appropriateness, then the time required for evaluation is reduced, but the reliability and accuracy of parental control deteriorates
Solution Approach 1:
Instead of relying on abstract rating labels, the patent creates visual copies (frames) of the actual content. These frames serve as direct visual representations that parents can evaluate intuitively, combining the speed of pre-processing with the reliability of direct content observation.
Solution Approach 2:
The patent uses visual encoding through frame selection and potentially color-coded watching levels to convey content appropriateness. The visual nature of frames provides intuitive information about content offensiveness without requiring parents to interpret complex rating scales.
3Ease of operation
If example content is shown to set parental lock levels, then ease of operation is improved, but reliability deteriorates when contents are similarly rated but perceived differently
Solution Approach 1:
The patent segments the audiovisual content into multiple frames, each representing different segments of the content. This segmentation allows parents to review multiple representative scenes rather than a single example, providing a more comprehensive and reliable basis for setting appropriate parental controls.
Solution Approach 2:
The system dynamically presents multiple frames that can be reviewed interactively. Parents can navigate through different frames and potentially request playback of specific segments, creating a flexible and adaptive review process that accommodates different parental preferences and concerns.
Data Source
AI summary
The invention discloses a method for setting a watching level to an audiovisual content which some frames are already annotated with watching levels. Upon the reception of the audiovisual content, frames annotated with watching levels are extracted and displayed in a single view. One of the displayed frames is selected by the user, the watching level of the selected frame being set as watching level to the audiovisual content.
