Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the first generation MOST network is used, then the system structure is simple and stable, but multimedia video transmission capability is not provided
Solution Approach 1:
The patent introduces a protocol conversion module as an intermediary between the first generation MOST network and multimedia data transmission requirements. This module converts standard MOST protocols into protocols suitable for multimedia video transmission, enabling the legacy network to support new functionality without requiring complete system replacement or increasing overall network complexity
Solution Approach 2:
The patent changes key transmission parameters of the MOST network protocol to enable multimedia video transmission. By modifying bandwidth allocation, data rate, and transmission timing parameters within the existing MOST framework, the system achieves video transmission capability while maintaining compatibility with the original network structure
2Adaptability or versatility
If multiple communication interfaces are integrated, then connectivity and adaptability are improved, but system complexity increases
Solution Approach 1:
The patent creates a universal gateway device that can handle multiple communication interfaces (MOST, USB, Ethernet, 1394) through a single integrated architecture. This multi-functional gateway consolidates what would otherwise be separate complex subsystems into one unified device, improving connectivity across different platforms while containing system complexity within a single manageable component
Solution Approach 2:
The gateway serves as an intermediary layer between diverse communication interfaces and the internal data sharing system. It provides protocol conversion and data format standardization, allowing multiple interfaces to be integrated without directly increasing the complexity of the core data sharing functionality
3Productivity
If dynamic bandwidth allocation is implemented, then data transmission efficiency is improved, but control complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the gateway continuously monitors data transmission status, bandwidth utilization, and service requirements. Based on this real-time feedback, the system dynamically adjusts bandwidth allocation for different services and devices, optimizing data transmission efficiency while keeping bandwidth management complexity manageable through automated control algorithms
Data Source
AI summary
A multimedia data sharing system and method for a MOST network is disclosed. The system provides a service management module, a data link control module, and a protocol conversion module. The service management module provides state analysis and management for all services of the multimedia data sharing system and records analyzed service states and configuration results in a service management list. The data link control module performs a control and management process for system data streams based on information stored in the service management list. The protocol conversion module retrieves data from a channel register, based on the information stored in the service management list, to perform a MOST link management operation and implements a packaged or an unpackaged operation to data packets for access of the MOST network.
