Media Stream Replication via World Context Extraction

Solution Overview

Problem

Conventional media sharing techniques require significant communication resources and speed is affected due to large data sizes, and user interaction with shared media is limited in terms of adjustment and flexibility.

Innovation Solution

A system and method that replicates a media stream by communicating world context and processing it to generate a media stream at the receiver device, allowing for flexible user adjustments without transmitting the entire media stream, using a transmitter device with input, applications, buffer, processor, and transceiver modules, and a receiver device with similar components for signal communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the entire media stream is communicated from source to recipient, then the recipient can access the complete video content, but substantial communication resources are required and communication speed is adversely affected due to large data size

Engineering Contradiction:

Improvecomplete media content deliveryVSAvoidcommunication bandwidth consumption

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent extracts only the essential world context data from the complete media stream. Instead of transmitting the entire video, the system identifies and communicates only the critical scene description, object positions, and contextual information needed to reconstruct the media experience at the recipient end, thereby reducing bandwidth consumption while maintaining content delivery reliability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent creates a simplified copy of the media stream in the form of world context data. Rather than transmitting the original high-bandwidth video stream, the system transmits a compressed representation that can be used to regenerate or approximate the media content at the recipient end, significantly reducing communication resource requirements

Inventive Principle:

Principle #26Copying

3Ease of operation

If the video is adjusted to full screen view at the receiving end, then user viewing experience is improved, but pixellation occurs if the video resolution is not suitable for full screen view

Engineering Contradiction:

Improveuser viewing flexibilityVSAvoidvideo quality

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The patent implements dynamic resolution adaptation by transmitting world context data that enables the recipient device to dynamically adjust the regenerated media stream resolution based on the display capabilities and user preferences. This allows the video to adapt to different screen sizes and resolutions without pixellation, as the content is regenerated rather than simply scaled

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the fundamental parameter of media transmission from fixed-resolution video streams to flexible world context data that can be regenerated at multiple resolutions. This allows the system to maintain video quality across different display configurations by adjusting the regeneration parameters at the recipient end rather than being constrained by the original transmission resolution

Inventive Principle:

AI summary

A method for replicating a media stream generated by a transmitter device. The method can include communicating world context generated at the transmitter device and processing the received world context. The generated world context is associable with description generated based on an application being run at the transmitter device. The generated world context can be based upon to generate the media stream in a manner such that description of the generated media stream can be associated with the description generated based the application being run. Processing of the received world context can be in a manner so as to replicate the media stream generated at the transmitter device. Description of the replicated media stream can correspond to the description of the media stream at the transmitter device. The received world context can be further processed in a manner so as to change the description associable with the replicated media stream.
