Solution Overview

Problem

Existing multimedia delivery systems face inefficiencies in unicast transmission models, lacking flexibility and personalization, and fail to optimize network resources for dynamic content distribution and delivery.

Innovation Solution

A multimedia capture, storage, and delivery system that utilizes a flexible, configurable network infrastructure to encode content into interim formats, applying time-to-frequency transformations and network coding, with feedback-driven adaptation for efficient storage and delivery tailored to client devices and network conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If media content is delivered over a network to a client, then accessibility and convenience are improved, but security risks increase due to potential interception or unauthorized access

Engineering Contradiction:
Improvemedia content accessibilityVSAvoidsecurity risks
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

A security module is introduced as an intermediary component between the media content delivery system and the client. This security module intercepts and validates security tokens before allowing media content to be accessed, thereby maintaining network-based accessibility while preventing unauthorized access. The security token acts as a mediator that verifies user authorization before media playback occurs.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If security tokens are validated on the server side, then security is improved, but network bandwidth consumption increases

Engineering Contradiction:
Improvesecurity validationVSAvoidnetwork bandwidth consumption
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

Security tokens are validated in advance before media content is delivered to the client. The server performs security validation beforehand and embeds the validated security token in the media content metadata. This preliminary validation approach ensures security reliability while reducing network bandwidth consumption during actual media playback, as no additional validation requests are needed during content delivery.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If security validation is performed before media playback, then security is improved, but playback time is delayed

Engineering Contradiction:
Improvesecurity validationVSAvoidmedia playback time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

Security validation is performed in advance during the media content delivery phase, before playback begins. The server validates the security token and prepares the authorized media content for immediate playback. By completing security validation beforehand, the system ensures security reliability while enabling seamless playback without delays during the actual media reproduction.

Inventive Principle:
Principle #10Preliminary action

4Reliability

If security tokens are embedded in media content, then security is improved, but device memory usage increases

Engineering Contradiction:
Improvesecurity token embeddingVSAvoiddevice memory usage
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

Security tokens are embedded only in the specific portions of media content where authorization is required, rather than throughout the entire media file. The security token is integrated into the media metadata or header sections where it can be efficiently validated without significantly increasing overall device memory consumption. This localized embedding approach maintains security reliability while minimizing impact on device memory resources.

Inventive Principle:
Principle #3Local quality

AI summary

A method for providing media content within a media distribution network. The method comprises transforming source media content into an interim format, thereby providing transformed content. Furthermore, the method comprises storing the transformed content on at least one core storage unit. In addition, the method comprises receiving a request for the source media content from a client. The method further comprises encoding the transformed content or intermediate coded content derived therefrom into encoded content suitable for transmission over a core network and/or an edge network, as well as sending the encoded content via the core network and/or the edge network to the client.
