Solution Overview

Problem

Conventional video conferencing systems require software installation, are not compatible with all operating systems and hardware platforms, and have poor wireless video playback performance, making them inconvenient for users to set up and use.

Innovation Solution

A video conferencing system that includes a transmitter and receiver, where the transmitter sends extended display identification data to an information processing apparatus to be recognized as a virtual display, allowing for wireless image signal transmission without the need for software or driver installation, and is compatible with various operating systems and hardware platforms through HDMI and USB Type-C alternate mode.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional video conferencing system uses software installation and driver configuration, then video conferencing function can be achieved, but operation complexity increases and plug-and-play capability is lost

Engineering Contradiction:

Improveplug and play operationVSAvoidsoftware installation and configuration

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the software-based video conferencing system with a hardware-based transmitter that directly interfaces with the information processing apparatus. The transmitter includes an image receiving unit, control unit, and wireless transmitting unit that collectively perform video conferencing functions through hardware circuitry rather than software installation, eliminating the need for drivers and configuration while maintaining full video conferencing capability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The transmitter is designed with universal compatibility to work with multiple operating systems and hardware platforms. It can receive image signals through various interfaces (HDMI, USB Type-C with DisplayPort format) and transmit wirelessly to receivers, making it adaptable to different devices without requiring device-specific software or configuration

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If conventional video conferencing system supports multiple operating systems and hardware platforms, then compatibility improves, but still requires information department support and setup assistance

Engineering Contradiction:

Improvecompatibility with operating systems and hardware platformsVSAvoidsetup convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

By replacing software with hardware, the transmitter achieves universal compatibility across operating systems and hardware platforms without requiring OS-specific drivers or configuration. The hardware interface directly communicates with the information processing apparatus through standard connections (HDMI, USB Type-C), eliminating the need for information department support while maintaining broad adaptability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If conventional video conferencing system uses software settings for mode switching, then presentation mode and video playback mode can be switched, but operation complexity increases and wireless video playback performance deteriorates

Engineering Contradiction:

Improvemode switching convenienceVSAvoidsoftware settings

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces software-based mode switching with hardware-based control. The transmitter includes a control unit that receives trigger signals to switch between presentation mode and video playback mode, and the receiver has corresponding control units that process these hardware signals. This hardware control eliminates complex software settings while improving wireless video playback performance through direct hardware signal processing

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system implements dynamic mode switching through trigger signals that can be sent from the transmitter to the receiver or from external controllers. The control units in both transmitter and receiver dynamically adjust their operation mode based on these hardware signals, enabling flexible switching between presentation and video playback modes without software intervention

Inventive Principle:

Principle #15Dynamics

AI summary

A video conferencing system is disclosed. The video conferencing system includes a transmitter and a receiver. When the transmitter is coupled to a port of an information processing apparatus, the transmitter communicates with the information processing apparatus to determine whether the port of the information processing apparatus has video output function. When the above determination result is no, the transmitter emits a wireless signal. The transmitter is coupled to a display apparatus and used to receive the wireless signal and provide a default warning message to the display apparatus.
