Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing media networks face inefficiencies and increased costs due to the need for additional bandwidth to transmit targeted content for local caching, which diminishes the value of household addressable networks.

Innovation Solution

Utilize unused bandwidth in existing transport streams to insert and transmit targeted content to receiver devices without requiring additional resources, using computational methods to analyze and manage bandwidth for efficient content storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If additional broadcast streams are used to transmit targeted content to receiver devices for local storage, then the targeted content can be accessed locally when needed, but this introduces inefficiencies and extra cost due to the need to handle extra bandwidth

Engineering Contradiction:

Improvecontent availabilityVSAvoidbandwidth utilization

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The existing broadcast stream is made multi-functional by simultaneously carrying both primary content and targeted content within the same bandwidth allocation. The system enables the transport stream to serve multiple purposes: delivering scheduled content while also providing targeted content elements to specific receiver devices without requiring separate dedicated streams.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system changes the parameter of bandwidth allocation by dynamically inserting targeted content elements into unused or underutilized portions of existing transport streams. Rather than allocating fixed additional bandwidth for targeted content, the system adapts the utilization of available bandwidth parameters to accommodate multiple content types within the same resource constraints.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If additional bandwidth is allocated to transmit targeted content for local caching, then receiver devices can store and access targeted content independently, but this increases operational costs and reduces the value of household addressable networks

Engineering Contradiction:

Improvecontent delivery flexibilityVSAvoidbandwidth resources

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The system applies partial action by inserting targeted content elements only in the portions of bandwidth that are unused or underutilized in existing transport streams. Rather than allocating full additional bandwidth, the system captures and utilizes only the excess or idle capacity that would otherwise go unused, thereby providing targeted content delivery without proportionally increasing total bandwidth consumption.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

Systems, methods and computer-readable storage media for storing or caching targeted content on a receiver device using existing bandwidth within a media network are described. For example, unused bandwidth within a transport stream may be detected and targeted content may be inserted into the transport stream within the unused bandwidth. The targeted content may include targeted advertisements for a household addressable media network. The transport stream may be transmitted to the receiver device which may access and store the targeted content responsive to various targeted content signals. For instance, the transport stream may include targeted content signals configured to trigger the receive device to access and store the targeted content. The transport stream may include a commercial feed transport stream.
