Network Device HDMI Cluster Database Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in easily acquiring and utilizing various kinds of information for each HDMI device within an HDMI cluster, such as connection status and unique device information, across a network.
Innovation Solution
A network device with a database registering HDMI CEC logical and physical addresses, along with acquisition destination information, allows for the processing and display of HDMI device information, including connection status and unique details, using a processing unit that can transmit this data to external devices via IP communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a database is established to register HDMI CEC addresses and device information, then information management capability is improved, but system complexity increases
Solution Approach 1:
The patent introduces a network device as an intermediary component that maintains the database and mediates between multiple HDMI devices and external devices. This centralizes information management, reducing the complexity burden on individual HDMI devices while improving information accessibility across the network.
Solution Approach 2:
The database structure is designed to store multiple types of information (HDMI CEC logical address, HDMI CEC physical address, acquisition destination information) in a unified format that can serve various HDMI devices with different functions. This universal structure improves information management while avoiding the need for separate complex database systems for each device type.
2Ease of operation
If acquisition destination information is registered for each HDMI device, then information accessibility is improved, but data storage requirements increase
Solution Approach 1:
The patent extracts only the essential acquisition destination information (such as URLs or identifiers) from the complete device information, storing only what is necessary to access unique device information. This reduces the quantity of data stored in the database while maintaining ease of information acquisition through direct access to external sources when needed.
3Adaptability or versatility
If the database is transmitted to external devices via IP communication, then information sharing capability is improved, but network bandwidth consumption increases
Solution Approach 1:
The network device pre-processes and structures the database information before transmission, organizing it in an efficient format that reduces redundant data transfer. This preliminary preparation minimizes the bandwidth consumption required for information sharing while maintaining adaptability across different external devices.
Solution Approach 2:
Instead of transmitting the entire database to every external device, the system transmits only the necessary portions or references to the database. External devices can access the full information through the network device, reducing network bandwidth consumption while maintaining information sharing capability across multiple devices.
Data Source
AI summary
It is made possible to easily acquire and use various kinds of information of each HDMI device in an HDMI cluster. A database in which at least an HDMI CEC logical address, an HDMI CEC physical address, and acquisition destination information for acquiring unique information are registered for each HDMI device in an HDMI cluster is included. A processing unit performs processing using this database. For example, the processing unit transmits the database to an external device. Also, for example, the processing unit displays an HDMI device in an HDMI cluster, a connection status thereof, and unique information of each HDMI device on the basis of this database.
