Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the multipoint processor performs coding and decoding operations on media data from different terminal equipment, then the video conference quality can be maintained, but the hardware demand increases and time delay increases
Solution Approach 1:
The patent extracts the coding and decoding functions from the multipoint processor and relocates them to terminal equipment. The multipoint processor only performs data mixing and distribution, while terminal equipment handles the computationally intensive coding and decoding operations, thereby reducing hardware demands on the central processor.
Solution Approach 2:
The patent introduces an adaptive bandwidth allocation mechanism as an intermediary between terminal equipment and the multipoint processor. This mechanism dynamically adjusts data transmission parameters based on network conditions, reducing the processing burden on the multipoint processor while maintaining video quality through optimized data flow management.
2Reliability
If the multipoint processor performs coding and decoding operations on media data, then video conference quality can be maintained, but time delay increases
Solution Approach 1:
The patent extracts the time-consuming coding and decoding operations from the multipoint processor and distributes them to terminal equipment. This parallelization of processing tasks significantly reduces the time delay in the video conference system while maintaining quality standards.
Solution Approach 2:
The patent implements preliminary action by having terminal equipment perform coding and decoding operations before data transmission. This pre-processing approach eliminates waiting time during the conference and reduces overall system latency.
3Reliability
If the multipoint processor handles all coding and decoding operations, then video quality can be controlled, but system efficiency decreases
Solution Approach 1:
The patent segments the video processing functions into different components: terminal equipment handles coding and decoding, while the multipoint processor handles data mixing and distribution. This functional segmentation improves system efficiency by allowing parallel operations and reducing the processing bottleneck at the central processor.
Solution Approach 2:
The patent implements self-service by enabling terminal equipment to autonomously perform coding and decoding operations without requiring centralized processing. This distributed approach improves system efficiency by utilizing local resources and reducing dependency on the multipoint processor's processing capacity.

AI summary
The present invention provides a video conference system. The video conference system includes a plurality of terminal equipment and a server. Each of the terminal equipment estimates and transmits real-time bandwidth and conference requirements to the server. A multipoint control unit of the server includes a multipoint controller and a multipoint processor. The multipoint controller determines, according to the real-time bandwidth and the conference requirements, a transfer rule and an allocation scheme corresponding to each of the terminal equipment. The multipoint processor receives the transfer rule and voice data stream or video data stream from the terminal equipment. The server transmits each of the allocation schemes to the corresponding terminal equipment. When any of the terminal equipment transmits new real-time bandwidth or new conference requirements to the server, the multipoint controller determines the transfer rule and the allocation schemes once again.
