Projector Self-Service Data Distribution for Wide Audience Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for projecting electronic data to a wide audience incur additional costs due to the need for a server to convert data into a universal format, making it difficult for distant viewers to recognize detailed content.
Innovation Solution
A communication apparatus and method that obtains, stores, and generates distribution data for projection images, detecting changes to distribute updated data while preventing redundant distribution, thereby eliminating the need for a dedicated server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a server is provided to convert electronic data to a universal format, then distant viewers can visually recognize detailed contents, but the cost of installing the server increases
Solution Approach 1:
The projecting apparatus performs the conversion function itself without requiring an external server. The conversion unit within the projecting apparatus converts electronic data to a universal format automatically, enabling the system to serve itself rather than relying on separate infrastructure.
Solution Approach 2:
The conversion function is merged with the projecting apparatus. By integrating the conversion unit into the projector, the patent combines multiple functions (projection and format conversion) into a single device, eliminating the need for a separate server and reducing overall system complexity.
2Measurement precision
If distribution data is generated for every projection image change, then all viewers can see detailed content changes, but redundant distribution occurs when images remain unchanged
Solution Approach 1:
The control unit monitors whether the projection image has actually changed before triggering distribution. This feedback mechanism prevents redundant distribution by verifying the actual change condition, ensuring distribution data is only generated when necessary.
Solution Approach 2:
The system performs a preliminary check to determine if the projection image has changed before generating distribution data. This preliminary action filters out unnecessary distribution operations, saving energy and resources while ensuring only actual changes are communicated to viewers.

AI summary
The communication apparatus obtains a projection image to be projected. In a case where a change from a first projection image to a second projection image has been detected, the communication apparatus distributes second distribution data based on the second projection image to an external apparatus. In a case where the second distribution data has already been distributed, the communication apparatus controls not to distribute data based on the second projection image as new distribution data.
