DVI Status Report Structure for Multi-Port Diagnostic Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital cable TV receivers can only transmit DVI link status information for one port to the POD module when multiple peripheral devices are connected, limiting diagnostic capabilities and accuracy.
Innovation Solution
A digital cable TV receiver with a DVI controller that generates and transmits a DVI status report including information for all connected DVI ports, using an expanded DVI Status Report Syntax within the Generic Diagnostic Protocol, allowing for real-time monitoring of multiple peripheral devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the DVI status report syntax is expanded to include information for all connected DVI ports, then diagnostic capabilities and accuracy are enhanced, but data structure complexity increases
Solution Approach 1:
The DVI status report is segmented into multiple fields, each representing a specific DVI port's status. Instead of a single aggregated status, the report divides information into discrete port-level status fields, allowing comprehensive diagnostic coverage while maintaining structured organization.
Solution Approach 2:
The status report transitions from a single-dimension status indicator to a multi-dimensional data structure that includes port identifier, connection status, and device type classification. This dimensional expansion enables comprehensive diagnostics without creating unmanageable complexity.
2Reliability
If status information for all DVI ports is transmitted to the POD module, then diagnostic capabilities are enhanced, but communication data volume increases
Solution Approach 1:
The status information uses standardized parameters and enumerated values (e.g., specific status codes, device type identifiers) to represent port states. This parameterization allows comprehensive status reporting with compact data representation, minimizing communication overhead while maximizing diagnostic information.
3Measurement precision
If the DVI status report includes differentiation between Input, Output, and Input/Output ports, then diagnostic accuracy is improved, but processing complexity increases
Solution Approach 1:
The system implements a standardized set of port type classifications (Input, Output, Input/Output) that covers all necessary diagnostic scenarios. This partial classification approach provides sufficient precision for diagnostic purposes without creating excessive processing complexity through over-classification.

AI summary
A communication system includes a plurality of Digital Visual Interface (DVI) ports. A content provider forwards a single DVI diagnostic request to a receiver, which includes a controller configured to receive the single DVI diagnostic request. The controller is further configured to collect DVI status information associated with each of the plurality of DVI ports in response to the single DVI diagnostic request.
