Solution Overview

Problem

Storing multiple copies or versions of content requires significant computer memory and storage, as different versions often share identical or similar sections, leading to inefficiency.

Innovation Solution

Storing a single copy of content with associated instructions that allow retrieval and output of alternate portions based on user preferences or interests, using an instruction interpreter and scheduler to manage playback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple copies or versions of content are stored to provide versioning features, then content delivery flexibility is improved, but computer memory and storage requirements increase significantly

Engineering Contradiction:
Improvecontent delivery flexibilityVSAvoidcomputer memory and storage
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The content is divided into separate video portions and audio portions that can be independently stored and selectively combined. Instead of storing complete duplicate versions, the system segments content into modular components (video tracks and audio tracks) that can be reassembled based on user preferences, thereby reducing storage requirements while maintaining versioning flexibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A single universal content file is stored that can serve multiple versioning purposes through the use of instructions and metadata. The content file contains embedded instructions that enable it to function as different versions (e.g., clean version, uncensored version) without requiring separate physical copies, thus achieving multi-functionality with minimal storage overhead.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple versions of content are stored with different audio or video portions, then user preference accommodation is improved, but storage efficiency deteriorates

Engineering Contradiction:
Improveuser preference accommodationVSAvoidstorage efficiency
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

Instructions and metadata are pre-embedded in the content file during content creation, specifying alternate audio portions and their corresponding timestamps. This preliminary action allows the playback system to efficiently retrieve and switch between different audio versions without requiring multiple complete content copies to be stored, thereby maintaining storage efficiency while accommodating user preferences.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Instead of storing multiple complete copies of content, the system stores a single master copy and creates virtual copies through selective retrieval of alternate portions using embedded instructions. This approach minimizes actual data duplication while enabling multiple version deliveries, improving storage efficiency without sacrificing user preference accommodation.

Inventive Principle:
Principle #26Copying

3Quantity of substance

If a single copy of content is stored with instructions for alternate portions, then storage efficiency is improved, but playback control complexity increases

Engineering Contradiction:
Improvestorage efficiencyVSAvoidplayback control
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The content file contains self-contained instructions and metadata that automatically guide the playback system on how to retrieve and switch between alternate audio portions. The embedded instructions specify timestamps, alternate audio locations, and switching conditions, allowing the system to self-manage the complexity of multi-version playback without requiring external control mechanisms, thus balancing storage efficiency with manageable playback control.

Inventive Principle:
Principle #25Self-service

AI summary

Systems and methods are described for retrieval and output of content in a way that addresses concerns with storing multiple copies or versions of a piece of content. The piece of content may have associated computer instructions that allow the client to access alternate portions of the piece of content during consumption. This allows the content provider to store a single copy of the complete piece of content while enabling consumers to access alternate audio or video portions of the content. A new playback architecture may execute instructions associated with a piece of content. Instructions associated with a piece of content may directly affect consumption by the consumer client and may be dependent upon user preferences or interests.
