Image Display Device Connection Management for Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image display systems where multiple image transmitting devices are connected to an image display device via a network, there is wasteful battery consumption when power saving mode is disabled unnecessarily, and issues arise with display state changes and connection limits when devices shift into power saving mode.
Innovation Solution
An image display device with a communication portion and a connection information management portion that maintains the number of connections by temporarily disconnecting image transmission systems when devices enter power saving mode, allowing for battery conservation and preventing display state changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power saving mode is disabled to maintain network connection for divided display, then image transmission reliability is improved, but battery consumption increases
Solution Approach 1:
The patent implements dynamic connection management where the image display device actively monitors the operational state of image transmitting devices and dynamically adjusts network connection status. When an image transmitting device is determined to be in a non-operational state (not requiring image transmission), the system dynamically disconnects the network connection, enabling power saving mode and reducing battery consumption while maintaining reliability when devices are actively transmitting images.
2Use of energy by moving object
If network connection is disconnected when image transmitting device is not operated, then battery consumption is reduced, but display state changes occur
Solution Approach 1:
The patent implements a feedback mechanism where the image display device continuously monitors the operational status of connected image transmitting devices. Based on this feedback information, the system intelligently determines whether to maintain or disconnect network connections. This feedback-driven approach ensures that connections are maintained only when needed for image transmission, reducing battery consumption while preventing unwanted display state changes through accurate state monitoring and appropriate connection management.
3Adaptability or versatility
If maximum number of connections is exceeded when one device is in power saving mode, then connection flexibility is improved, but new device connection fails
Solution Approach 1:
The patent implements preliminary action by proactively managing connection status based on the operational states of image transmitting devices. Before new connection requests are processed, the system预先 determines the connection status of existing devices and releases connections from devices in non-operational states. This preliminary connection management ensures that connection slots are available for new devices requiring image transmission, maintaining connection flexibility while ensuring successful new device connections.

AI summary
The present invention has a communication portion configured to establish an image transmission system for receiving an image signal from an image transmitting device via a network; and a connection information management portion configured to set the total number of the image transmission systems established for each of a plurality of the image transmitting devices as the number of connections, wherein the connection information management portion does not change the number of connections even if the image transmission system is disconnected, when the image transmitting device shifting into a power saving mode causes the image transmission system to be disconnected.
