Solution Overview
Problem
Current video call solutions face high service costs due to bandwidth requirements, unstable infrastructure, and high equipment prices, limiting the widespread adoption of video telephones.
Innovation Solution
A video-ready Internet telephone with a processor for video calls, but without a camera or LCD, allowing connection to external devices via ports, simplifying hardware and reducing costs, while maintaining compatibility with VoIP and MoIP protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera and LCD are equipped in the telephone to support video communication, then video call function is achieved, but the price of the telephone increases significantly
Solution Approach 1:
The patent extracts the camera and LCD from the telephone body, making them external peripheral devices connected via USB or other interfaces. The telephone only includes the processor with video processing capabilities, thereby removing the expensive components while retaining video call functionality through external devices.
Solution Approach 2:
The processor is designed to handle both voice and video processing functions, making it a multi-functional component. This allows the same device to support both VoIP and MoIP protocols, eliminating the need for separate dedicated hardware for video calls.
2Adaptability or versatility
If video data transmission is implemented, then video call capability is provided, but bandwidth consumption increases requiring higher service cost
Solution Approach 1:
The processor dynamically adjusts video compression parameters and transmission quality based on available network bandwidth. When bandwidth is limited, the system reduces video quality or switches to audio-only mode, thereby adapting to network conditions and reducing bandwidth consumption while maintaining call functionality.
3Adaptability or versatility
If the telephone is designed with video processing capabilities, then MoIP support is achieved, but device complexity increases
Solution Approach 1:
The patent merges video processing capabilities into the existing processor that also handles voice processing. By combining multiple functions (voice processing, video processing, compression, and transmission) into a single integrated processor, the system achieves MoIP support without significantly increasing device complexity or requiring separate dedicated hardware components.

AI summary
Disclosed is a video-ready Internet telephone which is compatible with a VoIP (Voice over Internet Protocol) telephone providing a voice communication service over the Internet. The video-ready Internet telephone includes a video processing module for converting a digital video signal into an analog video signal by using a communication protocol for video or converting an analog video signal applied thereto into an digital video signal for transmission through the Internet; and a video input/output module operated in cooperation with the video processing module, for receiving an analog video signal from a camera or receiving the converted analog video signal from the video processing module and displaying corresponding analog video data in response to the received analog video signal on a liquid crystal display (LCD).
