Wireless Terminal Valid Playing Time Alert Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of MP3 phones face difficulties in identifying and managing the expiration dates of valid playing times for multimedia data stored on their devices, leading to uncertainty about which files can no longer be played due to copyright restrictions.
Innovation Solution
A wireless communication terminal is equipped with a system that periodically checks the valid playing time of multimedia data, compares it with the total playing time, and outputs an alert or allows playback based on the comparison result, displaying remaining time and executing the media accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the valid playing time of multimedia data is limited to enforce copyright restrictions, then copyright protection is improved, but user convenience deteriorates because users cannot recognize the expiration dates of stored multimedia data
Solution Approach 1:
The system implements a feedback mechanism by periodically checking the valid playing time of stored multimedia data and notifying users when the valid playing time expires or is about to expire. This allows the system to maintain copyright protection while providing users with timely information about their media playback status, thus resolving the contradiction between enforcement and user convenience.
Solution Approach 2:
The terminal automatically performs the checking and notification functions without requiring user intervention. The system self-manages the monitoring of valid playing times and proactively informs users, eliminating the need for users to manually track expiration dates while maintaining copyright enforcement.
2Reliability
If multimedia data is stored with valid playing time limitations, then copyright compliance is improved, but information management deteriorates because users cannot identify which data is expired
Solution Approach 1:
The system provides continuous feedback to users about the playback status of their multimedia library. By periodically checking valid playing times and notifying users of expired or expiring content, the system maintains copyright compliance while ensuring users have complete information about their media inventory and playback eligibility.
Solution Approach 2:
The system performs preliminary checks and notifications before the valid playing time actually expires. By alerting users in advance when multimedia data is about to expire, the system allows users to take appropriate actions (such as purchasing additional playback rights or deleting files) before copyright violations occur, thus maintaining both compliance and information accessibility.

AI summary
Provided are a wireless communication terminal having a function of informing a valid playing time of multimedia data, and a method thereof. The wireless communication terminal informs a user of a valid playing time of multimedia data by checking the valid playing time of the multimedia data periodically, when a user has multimedia data and valid playing time downloaded and stored in the wireless communication terminal. The method for informing a valid playing time of multimedia data in a wireless communication terminal includes the steps of: a) storing multimedia data and valid playing time of the multimedia data; b) checking the valid playing time of the multimedia data periodically; and c) outputting an alert signal if a remaining time of the valid playing time of the multimedia data is in a range of an alert time.
