Refund-Aware Content Playback Tracking Across Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices lack the ability to determine whether purchased content is refundable and control playback accordingly, leading to inefficiencies in content management and increased network traffic.
Innovation Solution
A display device equipped with a processor that determines the refundability of purchased content by tracking playback time and point, storing relevant information, and managing playback through a control server, reducing network communication frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display device continuously communicates with the server to track playback information, then the playback control accuracy is improved, but the network traffic increases
Solution Approach 1:
The display device determines refundability and stores playback information (accumulated playback time and current playback point in time) locally before server communication is needed. This preliminary local processing reduces the need for continuous server communication, thereby reducing network traffic while maintaining accurate playback control.
Solution Approach 2:
The display device acts as an intermediary by maintaining local playback state information and only communicating with the server when necessary (e.g., when refundability determination is needed). This intermediary approach reduces continuous network traffic while preserving accurate playback control through local state tracking.
2Adaptability or versatility
If the display device stores detailed playback information for all content, then the content management capability is improved, but the device complexity increases
Solution Approach 1:
The display device stores detailed playback information (accumulated playback time and current playback point in time) selectively based on the refundability status of each content item. This local quality differentiation allows sophisticated content management for refundable content while simplifying storage for non-refundable content, thereby improving content management capability without uniformly increasing device complexity.
3Reliability
If the display device determines refundability for each playback request, then the content protection capability is improved, but the processing time increases
Solution Approach 1:
The display device determines refundability and stores the result in advance, before actual playback occurs. This preliminary determination eliminates the need to re-evaluate refundability with each playback request, thereby maintaining strong content protection capability while reducing processing time for subsequent playback requests.
Solution Approach 2:
The display device creates a local copy of the refundability determination result and stores it for future use. This copying approach allows the device to quickly reference previously determined refundability status without repeatedly querying the server or re-processing content protection logic, thus maintaining content protection while reducing processing time.
Data Source
AI summary
A display device includes a user input interface through which a playback request for specific content is received from a remote control device, a processor that acquires a content identifier (ID) for the specific content, the previous accumulated playback time for the specific content, and the playback point in time for the specific content based on the playback request, and a display that is configured in such a manner that the specific content is displayed on the display. The processor determines whether or not the purchase of the specific content is refundable. When it is determined that the purchase of the specific content is refundable, the processor stores the accumulated playback time and the current playback point in time at a specific interval of time.
