Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video conferencing technologies are limited by high costs, dedicated hardware requirements, and bandwidth usage, leading to isolation between low-cost, low-quality software-based solutions and high-cost, high-quality hardware-based solutions, with a need for a unified software solution that can provide optimal quality across heterogeneous devices and networks.
Innovation Solution
A software-based system that dynamically adjusts session parameters, such as bit rate and video settings, based on device hardware and network characteristics, allowing participants to connect from various devices and locations, and automatically adapts to changes during a video conference to maintain high-quality video and audio conferencing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hardware-based H.323 systems are used, then video conferencing quality is improved, but system cost and device complexity increase
Solution Approach 1:
The patent replaces traditional hardware-based H.323 video conferencing systems with software-based solutions that run on standard computing devices. The system uses software encoding and decoding of video and audio streams, eliminating the need for dedicated hardware video conferencing equipment while maintaining interoperability through standardized protocols.
Solution Approach 2:
The patent creates a universal software platform that can operate on diverse computing devices including desktops, laptops, and mobile devices with different operating systems. The system provides multi-point conferencing capabilities that work across heterogeneous devices, replacing the need for specialized hardware with a universal software solution.
2Adaptability or versatility
If software-based video conferencing solutions are used, then device compatibility and cost are improved, but video and audio quality deteriorate
Solution Approach 1:
The patent implements dynamic adaptation of video and audio stream parameters during conferencing sessions. The system continuously monitors network conditions and device capabilities, then adjusts encoding parameters such as bit rate, frame rate, and resolution in real-time to optimize quality for each participant's specific device and network environment.
Solution Approach 2:
The system changes encoding and transmission parameters dynamically based on detected network conditions and device capabilities. When network bandwidth is limited, the system reduces video resolution and frame rate; when bandwidth is available, it increases quality. This parameter adaptation allows high-quality conferencing on capable devices while maintaining compatibility with lower-end devices.
3Device complexity
If uniform video conferencing parameters are applied to all devices, then system simplicity is maintained, but quality optimization for individual devices is lost
Solution Approach 1:
The patent applies different video and audio parameters to each participant based on their individual device capabilities and network conditions. Each device receives customized stream parameters optimized for its specific hardware, operating system, and network environment, rather than using uniform parameters for all participants. This local optimization maintains simplicity at the system level while achieving quality optimization at the individual device level.
