Proxy Control for HDMI Command Translation Across IP Segments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In networks with devices connected via non-IP interfaces like HDMI, conflicts arise due to the inability of devices in different IP network segments to perform IP communication, leading to non-IP control system conflicts.
Innovation Solution
An information processing device with a first communication section for IP communication, a second communication section for non-IP wire interface communication, a proxy processing section to generate wire control commands from IP control commands, and a sharing processing section to share related information with other devices in different segments, avoiding conflicts by proxy control and command sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If devices in different IP network segments communicate via non-IP wire interface, then control functionality is extended to multiple segments, but control command conflicts occur between devices
Solution Approach 1:
The patent introduces a proxy device that acts as an intermediary between devices in different IP network segments. The proxy receives control commands from one segment, translates them into appropriate wire interface commands, and forwards them to devices in another segment. This intermediary mechanism enables cross-segment control while preventing command conflicts through centralized command management and translation.
2Ease of operation
If IP control commands are directly transmitted via wire interface, then control simplicity is maintained, but segment isolation causes communication failure
Solution Approach 1:
The patent changes the parameter of control commands by translating IP-based control commands into wire interface-specific commands (such as CEC commands for HDMI). The proxy device modifies command parameters including format, addressing, and protocol characteristics to match the target wire interface requirements, thereby enabling cross-segment communication while maintaining ease of operation through automated translation.
3Adaptability or versatility
If multiple devices perform proxy control independently, then control coverage is increased, but command collisions occur in the wire network
Solution Approach 1:
The patent implements a feedback mechanism where the proxy device monitors the wire network for ongoing control operations and command status. Before issuing new control commands, the proxy checks feedback information about current network state and adjusts its command issuance accordingly. This feedback-based coordination prevents command collisions while maintaining broad control coverage across multiple segments.

AI summary
A first communication section of an information processing device performs communication in a first segment of an IP network. A second communication section performs communication with other information processing devices via a non-IP wire interface. A proxy processing section generates a wire control command that is a control command using the wire interface on the basis of an IP control command that is a control command received from a first controller belonging to the first segment. The proxy processing section executes proxy processing on the basis of the wire control command by using the second communication section. The sharing processing section shares related information relating to a proxy control by the proxy processing section with a second information processing device belonging to a second segment.
