Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing Caller ID systems do not effectively integrate caller identification information into video streams, limiting users' ability to view caller details without answering the call, especially when dealing with encrypted digital video streams.

Innovation Solution

A method and apparatus that receive caller identifier information, convert it into textual form, and insert it into digital or analog video streams using a visual timecode video insertion format, allowing the information to be overlaid on the video signal, enabling display on various devices without requiring the call to be answered.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If Caller ID information is transmitted through traditional telephone equipment, then caller identification can be displayed on telephone displays, but the information cannot be integrated into video streams for display on video devices

Engineering Contradiction:

Improvedisplay device compatibilityVSAvoidcaller ID information accessibility

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The system enables Caller ID information to be displayed on multiple types of devices (traditional telephone displays and video devices) by integrating the information into video streams that can be processed by various display systems, making the solution universally applicable across different device types

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent uses video streams as an intermediary carrier to transport Caller ID information from the telephone network to video display devices, bridging the gap between traditional telephony systems and modern video display systems

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If digital video streams are encrypted for security, then transmission security is improved, but Caller ID information cannot be inserted into the encrypted stream

Engineering Contradiction:

Improvetransmission securityVSAvoidinformation insertion capability

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The system performs Caller ID information insertion before the video stream is encrypted, ensuring that the information is embedded in the clear stream where it can be properly integrated, and then the entire stream (including the inserted information) is encrypted together for secure transmission

Inventive Principle:

Principle #10Preliminary action

3Device complexity

If Caller ID information is displayed only on telephone equipment, then the system remains simple, but users cannot view caller details on video displays during video playback

Engineering Contradiction:

Improvesystem simplicityVSAvoiduser convenience

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The patent combines the Caller ID display function with the existing video display system by overlaying the caller information on the video stream, allowing users to view caller details on their video displays without requiring separate telephone equipment or additional devices

Inventive Principle:

Principle #5Merging (Combining)
