Cable Broadcast Receiver DVR Diagnostic Protocol
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current broadcast systems lack an efficient method for remotely monitoring and diagnosing the status of Digital Video Recorders (DVRs) connected to cable networks, particularly in cable broadcast receivers with bidirectional communication capabilities.
Innovation Solution
A diagnostic information transmission method and protocol are implemented, allowing a cable headend to request and collect DVR status information from a cable broadcast receiver, using protocols like the Generic Diagnostic Protocol, and transmitting this information back to the headend or displaying it to the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable broadcast receiver includes a DVR function or is connected to a DVR, then the system can record and store video content, but there is no efficient method for remotely monitoring and diagnosing the status of the DVR
Solution Approach 1:
The patent implements a feedback mechanism where the cable broadcast receiver periodically reports DVR status information (storage capacity, recording status, error logs) to the cable headend, enabling remote monitoring without requiring complex diagnostic equipment at the headend
Solution Approach 2:
The DVR status monitoring system is designed to be self-reporting, where the broadcast receiver autonomously collects and transmits diagnostic data about its DVR function, eliminating the need for manual diagnostics or complex remote probing mechanisms
2Productivity
If diagnostic information transmission protocol is implemented in cable broadcast receiver, then real-time remote monitoring of DVR functions is enabled, but the protocol integration increases system complexity
Solution Approach 1:
The diagnostic protocol is designed to be multi-functional, handling multiple types of status information (storage status, recording operations, error conditions) through a unified communication framework, reducing the need for separate protocols for each diagnostic function
Solution Approach 2:
The patent merges the diagnostic information transmission with the existing bidirectional communication infrastructure of the cable broadcast receiver, integrating DVR status reporting into the same communication channel used for content delivery and control
3Reliability
If DVR status information is collected and transmitted to cable headend, then proactive maintenance is facilitated, but data communication overhead increases
Solution Approach 1:
The system implements periodic status reporting where the broadcast receiver transmits DVR diagnostic information at predetermined intervals rather than continuously, reducing communication overhead while maintaining effective monitoring capability
Solution Approach 2:
The patent implements selective data transmission where only relevant DVR status parameters (storage capacity, error logs, operational status) are transmitted based on current system state, rather than transmitting all possible diagnostic data continuously

AI summary
A host is configured to communicate with a video data recording device. The host includes a host controller configured to receive a video data recording device diagnostic information request originated external to the host. The host controller further configured to collect the video data recording device diagnostic information from the video data recording device in response to the external request.
