Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing content distribution systems do not allow distributors to selectively choose and overlay advertisements in arbitrary areas of live content videos, limiting revenue generation opportunities.

Innovation Solution

A content distribution server and method that enables distributors to designate areas within a live content video for overlaying other content, select the content to be played in those areas, and generate and distribute the modified content to viewer terminals, allowing for dynamic and customizable ad placement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If advertisement content is superimposed on live content using traditional broadcasting technology, then revenue from advertisements can be increased, but the distributor cannot select specific advertisements from a distributor terminal

Engineering Contradiction:

Improvedistributor's ability to select advertisementsVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system separates the advertisement selection function from the superimposition function. The distributor terminal selects specific advertisement content from multiple candidates, while the superimposition is performed by the broadcasting system. This segmentation enables distributors to choose advertisements without requiring complex integrated systems at the distributor end.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system introduces an intermediary mechanism where advertisement selection information is transmitted from the distributor terminal to the broadcasting system, which then performs the actual superimposition. This intermediary approach allows the distributor to specify content preferences while the broadcasting infrastructure handles the technical superimposition, resolving the contradiction between selection capability and system complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If arbitrary areas of live content are used for content superimposition, then revenue generation opportunities are enhanced, but existing systems lack the capability to designate specific areas

Engineering Contradiction:

Improveflexibility in content placementVSAvoidease of implementation

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The system performs preliminary designation of superimposition areas by transmitting area specification information from the distributor terminal before the actual content superimposition occurs. This preliminary action allows flexible area selection while maintaining ease of implementation, as the area definitions are prepared in advance and simply applied during broadcasting.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system enables flexible content placement by allowing dynamic specification of superimposition area parameters (position, size, shape) without changing the fundamental broadcasting infrastructure. By parameterizing the area definitions, the system achieves high adaptability while keeping the implementation straightforward - distributors can adjust parameters through simple terminal operations.

Inventive Principle:

Principle #35Parameter changes

3Productivity

If dynamic ad placement and switching is implemented, then revenue generation is enhanced, but existing systems require special environments or chroma keying

Engineering Contradiction:

Improverevenue generation efficiencyVSAvoidenvironmental requirements

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system extracts the superimposition function from the distributor terminal and places it in the broadcasting system. This extraction eliminates the need for distributors to maintain special environments or chroma keying equipment, as the superimposition is performed centrally by the broadcasting infrastructure using standard technology.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system creates a virtual copy of the superimposition environment at the broadcasting system level, allowing dynamic ad placement without requiring physical special environments at the distributor location. The broadcasting system generates the composite video signal by digitally superimposing advertisement content onto live content, achieving the desired effect through software-based copying rather than physical setup.

Inventive Principle:

Principle #26Copying

AI summary

A content distribution server, includes: a communicator that receives live contents transmitted through a network NW from a distributor terminal used by a distributor of a live content; a designator that designates an area in the live content, where another content is superimposed and played; a selector that selects the other content to be played in the area designated; and a controller that generates a distribution content by superimposing the other content selected by the selector in the area designated by the designator in the live content, wherein the communicator distributes the distribution content to a viewer terminal through the network NW.
