Dwindling Buffer for Dynamic Multimedia Content Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia playback systems lack efficient methods for dynamically managing and filtering content events, such as violent, sexual, or objectionable content, during playback, especially for private home viewing, without storing complete copies of rated or unrated content.
Innovation Solution
A method involving a dwindling data storage medium that temporarily stores and filters multimedia content by downloading segments, deleting or overwriting them after display, and using a processor to manage content events, making imperceptible specific content types like sexual or violent events, and assembling altered segments for private viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complete copies of multimedia content are stored for playback, then content filtering and rating compliance can be implemented, but storage space is consumed and unauthorized dissemination risk increases
Solution Approach 1:
The multimedia content is divided into sequential segments that are downloaded and processed individually. The system downloads one segment at a time, processes it through filtering algorithms, displays it, then deletes it before downloading the next segment. This segmentation allows content filtering without storing the complete multimedia file, thus maintaining reliability while reducing storage space requirements.
Solution Approach 2:
The patent extracts and removes objectionable content events from the multimedia stream using content recognition algorithms. Identified objectionable segments are deleted or rendered imperceptible through techniques such as pixelation, blurring, or audio muting. This extraction process enables content filtering capability without requiring storage of the complete original content, as only processed portions are temporarily held.
2Reliability
If complete copies of multimedia content are stored, then content can be filtered and rated, but copyright compliance and unauthorized dissemination prevention become problematic
Solution Approach 1:
The system applies different quality treatments to different portions of the multimedia content based on their content classification. Objectionable segments are processed with degradation techniques (pixelation, blurring, muting) while non-objectionable segments maintain original quality. This local quality differentiation enables rating system compliance by making objectionable content imperceptible while preventing unauthorized dissemination of complete high-quality copies.
Solution Approach 2:
The system rapidly downloads, processes, and deletes each content segment in quick succession, rushing through the playback process without allowing complete copies to be stored. This skipping approach maintains rating compliance through real-time filtering while minimizing the window of opportunity for unauthorized copying or dissemination.
3Ease of operation
If multimedia content is downloaded and stored for playback, then content can be displayed, but memory space is consumed and dynamic content management becomes difficult
Solution Approach 1:
The system implements a discard-and-recover strategy where each multimedia segment is downloaded to memory, processed through content filtering, displayed to the user, then immediately deleted from memory. After deletion, the memory space is recovered and made available for downloading the next segment. This approach enables seamless content playback while maintaining efficient memory space utilization through continuous allocation and deallocation cycles.

AI summary
Several embodiments of present invention relate to indexing a multi-media presentation. The presentation can include a live broadcast or a recording. Several embodiments also include defining portions of digital data recordings based on the occurrence of content events. And, various embodiments relate to creating compilations of and/or access to video recordings based on occurrence of one or more content events recorded therein. Embodiments can include a dwindling buffer that temporarily stores segments of a presentation. The segments can include only temporarily stored segments with limited portions made imperceptible. The limited portions made imperceptible can include language, violent, sexual and drug-related content events. An altered segment can be assembled only on playback with an original recording so as to redact, skip, or otherwise render imperceptible the content event within the presentation without creating a fixed altered version thereof.
