Display Apparatus Slide Show Multi-Protocol Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems cannot perform slide shows using image data located across multiple locations, as they typically rely on internal storage or distribution servers, which limits flexibility and requires administrative access for updating images.
Innovation Solution
A display apparatus that connects via a network to acquire and display image data from multiple locations using different protocols, allowing images from various servers to be combined and updated without needing to store them on every device, enabling flexible content editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If image data is stored in internal storage or distribution server, then slide show can be performed, but the system cannot access image data from multiple locations and requires administrative access for updates
Solution Approach 1:
The display apparatus is designed to support multiple protocols (SMB and HTTP) for accessing image data from different locations. The controller can register address information from both SMB servers and HTTP servers, enabling the system to universally access image data from various sources without requiring separate systems for each protocol type.
Solution Approach 2:
The system enables non-admin users to update slide show content by directly inputting image data through the display apparatus. The controller automatically manages the update process by storing the input image data and refreshing the slide show without requiring administrative access or manual intervention from server administrators.
2Reliability
If images are stored on every device, then slide show can be performed locally, but storage space is wasted and updates require administrative access
Solution Approach 1:
The system extracts the image data storage function from individual display apparatuses and relocates it to external servers (SMB servers and HTTP servers). The display apparatus retains only the essential function of displaying images by acquiring data from registered address information, thereby eliminating the need to store duplicate copies on each device while maintaining local display capability.
3Adaptability or versatility
If multiple protocols are supported for accessing image data, then flexibility to access various servers is improved, but system complexity increases
Solution Approach 1:
The controller acts as an intermediary that manages multiple protocols (SMB and HTTP) through a unified interface. It registers address information from different protocol sources and handles the complexity of protocol-specific operations internally, presenting a simplified user experience where users can input images without needing to understand the underlying protocol differences.
Data Source
AI summary
A display apparatus that displays an image acquired via a network, the display apparatus includes a display unit configured to display information, and one or more controllers configured to register a plurality of pieces of address information including address information for image data accessible with a first protocol and address information for image data accessible with a second protocol, and acquire a plurality of pieces of image data based on the plurality of pieces of registered address information and sequentially display the plurality of pieces of acquired image data on the display unit.
