Storage Media Error Correction via Network Replacement

Solution Overview

Problem

Existing electronic entertainment devices cannot playback multimedia content if a storage media contains unreadable data, requiring replacement of the entire data file even if only a small portion is affected, leading to unnecessary resource consumption and inconvenience.

Innovation Solution

A multimedia player system that communicates with a server over a network to obtain and use replacement data for unreadable sections of a data file during playback, ensuring uninterrupted content delivery without needing to replace the entire storage media.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the entire data file is replaced when unreadable data is detected, then playback reliability is improved, but resource consumption and time loss increase

Engineering Contradiction:

Improveplayback reliabilityVSAvoidtime loss

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent segments the data file into readable sections and unreadable sections. Instead of replacing the entire file, the system identifies only the unreadable portions (such as scratched areas on optical media) and requests replacement only for those specific segments from a server, thereby reducing time loss while maintaining playback reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent extracts the problematic unreadable data portions from the overall data file. The system detects unreadable sections, isolates them, and requests only those specific portions to be replaced from a remote server, rather than replacing the entire file, thus minimizing resource consumption and time loss.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If the entire data file is replaced when unreadable data is detected, then playback reliability is improved, but loss of substance increases

Engineering Contradiction:

Improveplayback reliabilityVSAvoidloss of substance

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The patent segments the data file into readable sections and unreadable sections. Instead of replacing the entire file, the system identifies only the unreadable portions (such as scratched areas on optical media) and requests replacement only for those specific segments from a server, thereby reducing resource consumption while maintaining playback reliability.

Inventive Principle:

Solution Approach 2:

The patent extracts the problematic unreadable data portions from the overall data file. The system detects unreadable sections, isolates them, and requests only those specific portions to be replaced from a remote server, rather than replacing the entire file, thus minimizing resource loss.

Inventive Principle:

Principle #2Taking out (Extraction)

3Duration of action of moving object

If error correction techniques are used for unreadable data, then playback continuity is improved, but device complexity increases

Engineering Contradiction:

Improveplayback continuityVSAvoiddevice complexity

Core Design Contradiction:

Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The patent introduces a server as an intermediary between the playback device and the storage media. The server receives requests for unreadable data portions, provides corrected replacement data, and enables continuous playback without requiring complex error correction capabilities within the playback device itself, thus maintaining simplicity while ensuring continuity.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A data file on a storage media (28) is processed during playback or execution to identify unreadable data. Replacement data corresponding to the unreadable data is obtained over a communications network (54), and the replacement data is used to playback or execute the data file as if the data file does not contain any unreadable data.
