Remote Access for Non-IP Addressable Cablecard Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems face inefficiencies in diagnosing and addressing issues with access control modules in customer premises equipment, as these modules are not directly IP addressable, requiring physical presence of technicians to view diagnostic information.
Innovation Solution
A system that enables remote access to non-addressable access control modules through a host device configured to interface with a network server, using a table populated by the access control module's information, which is then sent over a communications network, allowing for parsing and display or storage of diagnostic data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If technicians physically visit customer locations to diagnose access control module problems, then they can directly view diagnostic information, but the process becomes time-consuming and expensive
Solution Approach 1:
The patent introduces a network server as an intermediary between the headend and the customer premises equipment. The server retrieves diagnostic information from the access control module via the host device and presents it to technicians remotely, eliminating the need for physical visits while maintaining full access to diagnostic data.
Solution Approach 2:
The patent replaces the mechanical/physical system of technician travel and on-site diagnosis with an electronic/network-based system. Diagnostic information is transmitted through communication networks, allowing remote access and eliminating the physical component of the diagnosis process.
2Reliability
If access control modules are made non-IP addressable for security reasons, then content copy protection and authentication are improved, but remote diagnostic capability is lost
Solution Approach 1:
The host device serves as an intermediary that the access control module can communicate with. The host device retrieves information from the access control module and forwards it to the network server, allowing remote access without requiring the access control module itself to be IP addressable.
Solution Approach 2:
The system is segmented into distinct functional components: the access control module (responsible for security functions only), the host device (responsible for communication and data retrieval), and the network server (responsible for presenting information). This segmentation allows the security module to remain non-IP addressable while still enabling remote diagnostics through other system components.

AI summary
A system for remotely accessing diagnostic information from an access control module includes a host device. The host device is configured to interface with the access control module over a direct connection to retrieve diagnostic information from the access control module in response to a host query from the host device, and to interface with a network server over an Internet protocol (IP) network to provide the diagnostic information relating to the access control module to the network server in response to a server query to an IP network address of the host device. The access control module is non-addressable in the IP network.
