Packet Converter Switch for Uncompressed Visual Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems are limited in communicating uncompressed visual information across networks, as they often require direct cable connections and lack flexibility in reaching multiple destinations, especially with the limitations of the DisplayPort specification version 1.1.
Innovation Solution
A packet converter switch that receives uncompressed visual information packets at display device ports, selectively directs them to network ports using an address resolution table, encapsulates these packets into network packets, and forwards them over a network, allowing communication through legacy networks to multiple destinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If DisplayPort specification version 1.1 is used for direct cable connection, then uncompressed visual information can be transmitted, but flexibility to reach multiple destinations is limited
Solution Approach 1:
The patent introduces DisplayPort network adapters as intermediary devices that convert DisplayPort packets into network packets (such as Ethernet packets). These adapters enable uncompressed visual information to traverse legacy network infrastructures by acting as mediators between the DisplayPort protocol and network protocols, thereby achieving multi-destination communication without requiring direct cable connections.
Solution Approach 2:
The patent segments the visual information transmission path into multiple independent hops through network adapters. Each adapter handles packet conversion and forwarding independently, allowing the visual information to be routed through multiple network nodes to reach different destinations. This segmentation enables flexible routing while maintaining uncompressed quality.
2Quantity of substance
If visual information is compressed until rendered by graphics card, then bandwidth is reduced, but loss of uncompressed visual information quality occurs
Solution Approach 1:
The patent implements dynamic packet encapsulation where DisplayPort packets are selectively converted to network packets based on transmission needs. The system dynamically adapts the data format for network transmission while preserving the uncompressed nature of the visual information, allowing efficient bandwidth utilization without quality loss.
Solution Approach 2:
The patent changes the packaging parameters of visual information by encapsulating DisplayPort packets within network packets (such as Ethernet frames). This parameter change in data structure allows the same uncompressed visual information to be transmitted over network infrastructures with different bandwidth characteristics, optimizing transmission efficiency while maintaining quality.

AI summary
DisplayPort micropackets of uncompressed visual information are adapted to conventional network infrastructure with a switch having DisplayPort ports, network ports and a packet converter. The packet converter encapsulates DisplayPort packets for communication through network ports and extracts DisplayPort packets from network packets for communication through DisplayPort ports. An address resolution table associates the switch ports with each other and with a packet converter operation by using a control field that defines the packet converter operation for information received at each port, such as encapsulation, extraction or native switching.
