Media Player Defect Detection and Server-Based Data Substitution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional media playback systems fail to seamlessly replace damaged media data during playback, leading to interruptions and unreadability due to physical defects in storage devices like scratched DVDs or CDs, which prevents smooth audio/video streaming.
Innovation Solution
A system and method that utilize a media management server to detect defects in storage devices and retrieve replacement data in real-time, allowing seamless playback by storing the replacement data in accessible regions of the storage device or external storage, and ensuring that the original defective data is not used again.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional media playback systems are used, then the system structure is simple, but playback interruptions occur due to damaged media data
Solution Approach 1:
A server acts as an intermediary between the media player and the storage device. When defective data is detected during playback, the player requests replacement data from the server, which provides substitute data from its database. This mediator approach enables seamless playback recovery without requiring complex error correction hardware in the player itself.
Solution Approach 2:
The server pre-stores replacement data for known defective regions in its database before playback occurs. When a player encounters damaged data, the substitution can happen immediately using pre-prepared replacement data, rather than requiring real-time error correction or re-fetching from the damaged storage device.
2Productivity
If real-time data substitution is implemented, then playback smoothness is improved, but data processing time increases
Solution Approach 1:
Replacement data is pre-stored in the server's database for known defective regions. When playback encounters damaged data, the substitution occurs immediately by retrieving pre-prepared data from the server rather than performing real-time error correction or fetching from the damaged source, eliminating playback interruptions.
Solution Approach 2:
The system creates and stores copy data in the server database that corresponds to defective regions on the original storage device. During playback, when defective data is detected, the system retrieves the pre-stored copy from the server, enabling seamless substitution without requiring complex real-time processing or multiple physical copies of the media.
3Reliability
If replacement data is stored in accessible regions, then subsequent playback reliability is improved, but storage space requirements increase
Solution Approach 1:
The storage solution is segmented into two parts: the original storage device containing the primary media data, and the server database containing replacement data for specific defective regions. This segmentation allows the system to store only the necessary replacement portions centrally rather than duplicating entire media files locally, optimizing storage efficiency while ensuring playback reliability.
Data Source
AI summary
A media player is utilized to determine presence of defects in storage devices, and to retrieve replacement data from media management servers. The retrieval of the replacement data is performed during playback and/or use of the storage devices. The replacement data is only utilized during real time playback of the storage devices. The replacement data can also be stored within the data storage player, into the storage devices, and/or into external storage devices accessible during playback operations. Addressing information is created and/or modified to enable use of stored replacement data. A new copy of the data can be created in the same or in new storage device. The media management server performs access authentication operations during replacement data retrieval. The media management server is accessed via user-based webpage-like interfaces and/or dedicated APIs.
