Solution Overview

Problem

Conventional chroma key techniques in broadcasting transmit a uniform background image, limiting users to viewing the same background, which lacks personalization and fails to incorporate user-specific content or preferences.

Innovation Solution

An electronic device processes circuitry to receive a broadcast image and synthesize it with a personalized background image using a chroma key, allowing users to select or receive background images based on personal preferences, user information, or social connections from a background providing server, enabling each user to view the broadcast with a unique background.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a uniform background image is transmitted using chroma key technique, then the broadcasting system is simple and easy to implement, but user personalization and engagement are limited

Engineering Contradiction:

Improveuser personalizationVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments the background image transmission by separating the broadcast image from the background image, allowing independent selection and synthesis of personalized backgrounds at the receiving end without complicating the broadcasting infrastructure

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple background images are prepared and stored in advance at the receiving end device, enabling users to select from pre-available options without real-time processing delays, thus achieving personalization without significant system complexity increase

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If a uniform background image is used for all users, then the broadcasting system is simple to operate, but user engagement and viewing experience are reduced

Engineering Contradiction:

Improveoperation simplicityVSAvoidbackground variety

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The receiving end device enables users to autonomously select and apply personalized background images from stored options or locally saved images, eliminating the need for complex server-based background selection systems while maintaining operational simplicity

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Each user's device stores and processes background images locally, allowing personalized background selection without requiring centralized control or complex network coordination, thus maintaining ease of operation while enabling background variety

Inventive Principle:

Principle #3Local quality
