Solution Overview

Problem

In video conference systems, resource utilization is low due to pre-reserved conference rooms being occupied even after meetings end early, leading to waste of system resources like bandwidth and conference room resources.

Innovation Solution

A control method for multimedia conference terminals that determines whether multimedia information meets preset conditions regarding audio and video activity, such as volume and presence of participants, to decide when to close the terminal, thereby optimizing resource usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conference rooms are reserved in advance for long periods to ensure smooth conferences, then conference reliability is improved, but resource utilization rate deteriorates

Engineering Contradiction:
Improveconference reliabilityVSAvoidresource utilization rate
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements dynamic conference room management by continuously monitoring conference status and automatically releasing resources when conferences end early. The system dynamically adjusts resource allocation based on real-time conditions rather than static pre-reservation, resolving the contradiction between ensuring conference reliability and maximizing resource utilization.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent employs feedback mechanisms by monitoring conference termination status and using this information to automatically release conference room resources. The system receives feedback about actual conference duration and adjusts resource allocation accordingly, preventing resource waste while maintaining conference reliability through proactive resource management.

Inventive Principle:
Principle #23Feedback

2Stability of the object's composition

If terminals remain occupied after conferences end early, then conference stability is maintained, but system resource efficiency deteriorates

Engineering Contradiction:
Improveconference stabilityVSAvoidsystem resource efficiency
Core Design Contradiction:
Stability of the object's compositionVSLoss of energy

Solution Approach 1:

The patent applies preliminary action by proactively detecting conference termination and automatically releasing terminal resources before they cause system inefficiency. The system anticipates resource waste and takes preventive action to release occupancy information, maintaining conference stability while improving system resource efficiency through timely resource liberation.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If multiple software terminals join the same conference, then system adaptability is improved, but resource management complexity increases

Engineering Contradiction:
Improvesystem adaptabilityVSAvoidresource management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements universality by creating a unified resource management mechanism that handles multiple terminal types (hardware and software terminals) through the same occupancy release process. The system uses a universal approach to monitor and release resources regardless of terminal type, improving adaptability while simplifying resource management complexity through standardized handling.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Embodiments of the present disclosure provide a control method of a multimedia conference terminal and a multimedia conference server. The control method of the multimedia conference terminal includes: determining whether multimedia information of a conference site collected by the multimedia conference terminal meets a preset condition; if the multimedia information does not meet the preset condition, acquiring multimedia information of the conference site collected by the multimedia conference terminal; and if the multimedia information meets the preset condition, closing the multimedia conference terminal.
