Display Device Rerun Notification Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in conveniently receiving rerun notifications for registered programs and managing memory efficiency in display devices, particularly when accessing VOD servers, as existing systems lack efficient mechanisms for real-time notifications and program updates.
Innovation Solution
A display device equipped with a memory, display module, and network interface that registers programs for rerun notifications, generates a VOD program guide by receiving additional information from a VOD server, and outputs messages when registered programs are available, enhancing user convenience and memory efficiency by providing real-time rerun service notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the display device continuously monitors VOD server for program updates to provide real-time rerun notifications, then the notification responsiveness is improved, but the memory usage and processing load increase
Solution Approach 1:
The system performs preliminary actions by pre-registering programs for rerun notification before actual updates occur. The controller maintains a registration list of programs and proactively checks for updates when new programs are uploaded to the VOD server, rather than continuously monitoring all programs. This allows timely notifications while reducing unnecessary memory usage and processing load.
Solution Approach 2:
The system implements periodic action by checking for program updates at specific intervals or when triggered by server notifications, rather than continuous monitoring. The controller periodically queries the VOD server for newly uploaded programs that match registered programs, balancing notification timeliness with reduced resource consumption.
2Ease of operation
If the display device automatically searches for registered programs on VOD server to provide rerun notifications, then the user convenience is improved, but the network bandwidth and processing resources are consumed
Solution Approach 1:
The system extracts only the necessary information by searching for registered programs specifically on the VOD server rather than scanning all available content. The controller identifies and retrieves only the program metadata relevant to registered programs, minimizing network bandwidth consumption and processing resources while maintaining high user convenience through automatic program detection.
Solution Approach 2:
The system uses feedback mechanisms where the VOD server provides update information about newly uploaded programs, and the controller uses this feedback to automatically identify and notify users about registered programs. This feedback loop enables convenient automatic searching while reducing processing resources by leveraging server-side information rather than requiring comprehensive client-side scanning.

AI summary
A display device includes a memory, a display module, a network interface configured to access a Video On Demand (VOD) server, and a controller configured to register a program for a rerun notification service, display a VOD program guide by receiving an additional information on a plurality of VOD program from a VOD server via the network interface, detect whether the additional information on the registered program exists in the VOD program guide, and output a message indicating that the program is uploaded in the VOD program guide via the rerun notification service if the additional information on the registered program exists in the VOD program guide.
