PVR Email Alert Service for Missed Recordings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Personal Video Recorders (PVRs) and PC-based systems often miss recordings due to hardware or software issues, especially when unmonitored for extended periods, leading to user frustration when trying to catch up on missed programs.
Innovation Solution
A web-based service that provides notifications to users about their scheduled and recorded broadcast content, offering routine summaries and urgent alerts when issues arise, such as scheduling conflicts or system problems, using email, SMS, or instant messages, to manage and maintain recording schedules effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the PVR operates autonomously without user monitoring, then the user can enjoy convenience and freedom from frequent checks, but the reliability of recording operations deteriorates as hardware or software issues may go undetected and cause missed recordings
Solution Approach 1:
The system implements automated feedback mechanisms where the PVR continuously monitors its own operational status, recording completion, and system health. Status information is automatically transmitted to users via email or SMS notifications, enabling the system to self-report issues without requiring manual user checks while maintaining recording reliability through automated oversight
Solution Approach 2:
The PVR performs self-diagnosis and self-monitoring of its recording operations, automatically detecting hardware or software problems and initiating error reporting procedures. The system serves itself by autonomously tracking recording status, managing error logs, and communicating with users only when necessary, thereby maintaining both convenience and reliability
2Reliability
If the user frequently monitors the PVR to ensure proper operation, then the reliability of recording operations improves, but the ease of operation deteriorates as the user must dedicate time and attention to checking status
Solution Approach 1:
The system provides automated feedback to users through electronic notifications that inform them of recording status, errors detected, and system health. This eliminates the need for users to manually monitor the PVR while ensuring they receive timely information about any issues, thereby maintaining reliability without sacrificing convenience
Solution Approach 2:
The patent introduces an intermediary notification system (email/SMS gateway) that acts as a mediator between the PVR and the user. This intermediary automatically communicates system status and errors to the user, allowing the PVR to operate autonomously while keeping the user informed, thus resolving the contradiction between monitoring reliability and user convenience
3Reliability
If error detection and notification systems are implemented, then the reliability of recording operations improves through timely error detection, but the device complexity increases due to additional monitoring and communication components
Solution Approach 1:
The notification system is designed to handle multiple functions through a single integrated mechanism: it monitors recording status, detects errors, formats notifications, and transmits alerts via email or SMS. By consolidating these functions into a unified error reporting subsystem, the patent minimizes the increase in device complexity while achieving improved reliability through comprehensive monitoring
Data Source
AI summary
A web-based service which provides a notification such an email to a user to facilitate managing the recording of broadcast content using a personal video recorder (PVR). The user can agree to participate in the service in exchange for emails which can provide information such as a summary of programs recorded over a few days, missed recordings, and scheduling conflicts. The notification can include targeted recommendations, targeted advertising and information about recording habits of members of a social network of the user. A notification can be provided on an urgent basis if program schedule conflicts or hardware or software problems with the user's equipment are detected. The user's equipment can include a PC-based PVR, or a PC which communicates with a separate PVR device. PC-related information such as events thrown can also be reported up to the web service.
