DVR Corrupted Content Detection and Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital video recorders (DVRs) often record corrupted content due to inclement weather or power outages, leading to poor reception and quality issues, which existing technologies fail to effectively detect and correct.
Innovation Solution
A method is implemented within DVRs to detect corrupted content using various techniques such as signal strength detection, power outage detection, and user demarcation, and to notify users through graphical interfaces, with the option to replace corrupted segments with uncorrupted content from a content provider or satellite service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If DVRs record broadcasted content continuously, then recording completeness is improved, but corruption risk increases due to weather or power outages
Solution Approach 1:
The system performs preliminary actions by detecting corruption during the recording process itself, rather than waiting until playback. The corruption detection mechanism continuously monitors recorded segments and identifies corrupted portions while the recording is still in progress, allowing for immediate notification and potential re-recording before the user needs to play back the content.
Solution Approach 2:
The system implements feedback by notifying the user about corrupted content through the graphical interface. When corruption is detected, the system provides feedback to the user indicating which segments are corrupted, enabling the user to make informed decisions about re-recording or alternative content sources.
2Measurement precision
If DVRs detect and notify users of corrupted content, then content quality control is improved, but device complexity increases
Solution Approach 1:
The system achieves multi-functionality by integrating corruption detection, quality assessment, and user notification capabilities within the existing DVR infrastructure. The corruption detection mechanism leverages existing recording and playback components, adding quality control functionality without requiring entirely separate hardware systems.
Solution Approach 2:
The graphical interface serves as an intermediary between the corruption detection mechanisms and the user. Rather than requiring complex direct interaction with detection algorithms, the system uses the familiar graphical interface to present corruption information in an accessible format, simplifying the user experience while maintaining sophisticated detection capabilities.
3Manufacturing precision
If DVRs replace corrupted segments with uncorrupted content, then content quality is improved, but loss of time occurs during replacement or re-recording
Solution Approach 1:
The system performs preliminary detection of corruption during the original recording process, so that when replacement or re-recording is necessary, the exact corrupted segments are already identified. This preliminary identification reduces the time required for replacement by eliminating the need for trial-and-error or extensive quality checking during the replacement process.
Solution Approach 2:
The system can obtain replacement content through copying from alternative sources such as other recorded instances or content providers. Rather than requiring complete re-recording, the system can copy uncorrupted segments from available sources and replace only the corrupted portions, significantly reducing the time investment required.
Data Source
AI summary
Embodiments of the invention include a method that comprises recording broadcasted television content and determining if one or more segments of the content is corrupted. The method can also present a notification if the content is corrupted, where the notification can include indicia such as a pop-up window, an icon or symbol in a program guide screen or program recorded content screen, and/or an indicator on the DVR unit. The method can also acquire uncorrupted content to replace one or more segments of the corrupted content.
