Display Control Device for Digital Signage Content Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In digital signage content distribution systems, the increased workload on display devices can lead to content distortion and malfunctions, particularly when handling large video files, compromising the reliability and quality of the displayed content.
Innovation Solution
A content distribution system that includes a server device, a display device, and a display control device, where the server transmits a display request and distributes content to the display control device, which stores alternative content for seamless display in case of errors, ensuring continuous and high-quality content delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If content is received and displayed simultaneously on the display device, then content distribution functionality is improved, but display reliability deteriorates due to increased workload and potential malfunctions
Solution Approach 1:
The patent divides the content handling process into two separate functional units: a content receiving unit that receives content from the server, and a content display unit that displays content on the display device. This segmentation prevents the display device from performing both receiving and displaying operations simultaneously, thereby maintaining display reliability while enabling continuous content distribution.
Solution Approach 2:
The patent implements a mechanism where the display device switches to alternative content before the actual content reception begins. The server sends a display request signal before transmitting the content, allowing the display device to prepare by switching to alternative content in advance. This preliminary action prevents display malfunctions during the content reception process.
2Speed
If large video content files are read and written simultaneously, then content update speed is improved, but display quality deteriorates due to distortion and malfunctions
Solution Approach 1:
The patent separates the content reception operation from the content display operation into distinct functional units. The content receiving unit handles large video file receptions while the content display unit maintains stable display of alternative content. This segmentation eliminates the quality deterioration caused by simultaneous read-write operations on large files.
Solution Approach 2:
The patent prepares alternative content in advance and switches to it before the actual content reception begins. This cushioning mechanism ensures that even if large video files cause system strain during reception, the display quality is maintained through the pre-prepared alternative content, preventing distortion and malfunctions.
3Loss of time
If the display device processes received content in real-time, then content distribution responsiveness is improved, but system stability deteriorates due to increased workload
Solution Approach 1:
The patent divides the system into distinct functional units: a content receiving unit that handles content reception and a content display unit that handles display operations. This segmentation allows the display device to maintain stable operation by not processing received content in real-time, while still achieving responsive content distribution through the coordinated operation of separate units.
Solution Approach 2:
The patent introduces a display control device as an intermediary between the server and the display device. This intermediary coordinates the content distribution process, managing the timing and sequencing of content reception and display operations. The intermediary enables responsive content distribution while maintaining system stability by preventing the display device from being overloaded with real-time processing tasks.

AI summary
A content distribution system includes: a server device that distributes a content; a display device capable of displaying the content; and a display control device that controls display of the content received from the server device on the display device, in which, in a case where the display control device receives the content from the server device, the display device displays an alternative content.
