Video Port Mapping via Encoder-Decoder Auto Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manually configuring correspondences between encoders and decoders to video ports in networked devices is complex and error-prone, particularly in medical environments like operating rooms, where encoders and decoders are tightly fitted and connected via fiber cables, requiring manual entry of serial IDs which is time-consuming and prone to errors.
Innovation Solution
A method for automatically mapping communications ports of a networked device to encoders and decoders using a network management application, Extended Display Identification Data (EDID) information, and Display Data Channel (DDC), as well as embedding port-specific and decoder-specific information within video signals, to determine correspondences without user intervention.

Engineering Contradiction Analysis
1Productivity
If manual configuration of encoder-decoder correspondences is performed, then installation flexibility is maintained, but installation time increases and error rate increases
Solution Approach 1:
The system performs self-configuration by automatically detecting encoders and decoders on the network, extracting their serial IDs, and creating correspondences without technician intervention. The networked device queries the network to identify connected devices and automatically maps ports to devices based on exchanged identification information.
Solution Approach 2:
The system exchanges identification information (serial IDs) during the initial connection phase before actual video routing is established. This preliminary automatic configuration eliminates the need for subsequent manual setup steps.
2Reliability
If manual entry of serial IDs is required, then configuration accuracy can be verified, but error rate increases and time consumption increases
Solution Approach 1:
The system replaces the manual mechanical process of reading and writing serial IDs with an automated electronic information exchange process. Identification data is transmitted digitally through the network and video interfaces, eliminating manual transcription errors.
Solution Approach 2:
The system automatically copies serial ID information from the encoder/decoder devices through their interfaces and stores it in the mapping table, eliminating the need for manual copying and reducing transcription errors.
3Measurement precision
If technicians manually inspect and enter serial IDs, then connection accuracy can be ensured, but the process becomes complex and error-prone
Solution Approach 1:
The networked device automatically performs the complex task of identifying connected encoders and decoders, extracting their serial IDs, and creating accurate mappings without requiring technician expertise in these procedures.
Solution Approach 2:
The system uses the video signal interfaces and network communication as intermediaries to automatically transfer identification information between devices, eliminating the need for direct manual inspection and reducing configuration complexity.
4Area of stationary object
If encoders and decoders are tightly fitted in racks, then space efficiency is improved, but accessibility for manual configuration decreases
Solution Approach 1:
The system replaces manual physical access to devices with automated electronic identification through existing video and network interfaces. Technicians no longer need to physically reach into racks to read serial IDs, as the system automatically extracts this information digitally.
Solution Approach 2:
The video signal cables and network connections serve as intermediaries that automatically transmit identification information from tightly fitted devices to the configuration system, eliminating the need for direct physical access to device labels.
