Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing content streaming technologies struggle to efficiently manage and deliver content streams comprising multiple tracks (audio, video, data) to user devices, often overwhelming viewers with too much information and failing to adapt to different content types and device capabilities.

Innovation Solution

A method that involves determining attributes of the content stream, retrieving a framework associated with those attributes, and preparing an output content stream according to the framework, which defines the arrangement of tracks to be included, processed, or weighted, ensuring optimal delivery based on user device capabilities and content type.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If multiple tracks (audio, video, data) are included in a single content stream, then the quantity of information provided to the viewer increases, but the ease of operation deteriorates as it becomes overwhelming to find relevant content

Engineering Contradiction:

Improvequantity of informationVSAvoidease of finding relevant content

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The content stream is segmented into multiple independent tracks (audio tracks, video tracks, data tracks), each carrying specific types of information. This segmentation allows the system to provide comprehensive information while enabling selective delivery based on user preferences and device capabilities, thereby maintaining ease of operation despite the quantity of information available.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different tracks within the content stream are assigned different qualities and priorities based on their importance and the viewer's needs. Critical information is delivered with higher quality while less important content can be reduced or filtered, making the interface more manageable and easier to navigate despite the presence of multiple information streams.

Inventive Principle:

Principle #3Local quality

2Device complexity

If a fixed content stream arrangement is used, then the device complexity is reduced, but the adaptability deteriorates as it cannot adjust to different content types and device capabilities

Engineering Contradiction:

Improvedevice complexityVSAvoidadaptability to content types

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The content stream arrangement is made dynamic rather than fixed, allowing it to automatically adapt to different content types, viewer preferences, and device capabilities. The system can reconfigure track arrangements, priorities, and delivery parameters in real-time based on detected conditions, maintaining simplicity while achieving high adaptability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes key parameters of the content stream arrangement (such as track ordering, visibility, audio-video synchronization, and data delivery rates) based on the detected content type and device characteristics. This parameter-based adaptation allows a single system to handle diverse content scenarios without increasing operational complexity for the user.

Inventive Principle:

Principle #35Parameter changes

3Loss of information

If all tracks are transmitted to ensure complete information delivery, then the loss of information is minimized, but the loss of energy increases due to unnecessary data transmission

Engineering Contradiction:

Improveinformation completenessVSAvoidenergy consumption

Core Design Contradiction:

Loss of informationVSLoss of energy

Solution Approach 1:

The system extracts and transmits only the necessary tracks based on viewer preferences, device capabilities, and content importance. Unnecessary or low-priority tracks are excluded from the transmission, reducing energy consumption and network resources while maintaining information completeness for the actual content the viewer needs.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of transmitting all possible tracks, the system applies partial action by selectively delivering only the essential tracks required for the current viewing context. This partial transmission approach reduces energy consumption and network load while ensuring that the viewer receives sufficient information without waste.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

There is provided a method of sending a content stream, comprising retrieving a sender framework associated with the at least one attribute, wherein the sender framework defines an arrangement of the plurality of tracks to be included in an output content stream. The output content stream is defined according to the sender framework. There is also provided a method of outputting a content stream on a user device, comprising receiving a content stream as defined by a sender framework, retrieving a user framework associated with the user electronic device, wherein the user framework defines at least one predetermined setting or instruction to be applied to the content stream, and applying the user framework to the content stream to update the content stream. The method may also include providing viewer engagement information and updating the sender framework in response to the viewer engagement information received.
