Broadcast Receiver Memory Diagnostic On-Screen Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As cable broadcast services become more complex, the memory capacity in existing broadcast receivers becomes insufficient, leading to operational issues, which cannot be resolved by replacing leased set-top boxes with new ones.
Innovation Solution
A broadcast receiver and method that allows users to request and display memory status information on-screen, using a host controller to collect and display diagnostic information via an on-screen display window, enabling users to assess memory allocation and select appropriate downloadable applications or data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If services provided by the headend become more complicated and various, then service functionality is improved, but memory capacity becomes insufficient
Solution Approach 1:
The patent implements a feedback mechanism where the host controller continuously monitors memory usage status and provides diagnostic information to the user. When memory capacity becomes insufficient due to increased service complexity, the system detects this condition and notifies the user through on-screen display, enabling informed decision-making about application installation and memory management.
2Ease of manufacture
If memory capacity is fixed at product development time, then manufacturing cost is reduced, but operational reliability deteriorates as services evolve
Solution Approach 1:
The system enables users to self-monitor memory status through diagnostic information displayed on-screen. Users can independently assess whether their host has sufficient memory capacity for desired applications and make informed decisions about application installation, eliminating the need for manufacturer intervention or system replacement.
3Ease of operation
If diagnostic information is provided to users, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The host controller, which already exists for general system control, is extended to perform the additional function of monitoring memory status and generating diagnostic information. This multi-functional approach allows the system to provide user-friendly memory management capabilities without adding separate dedicated hardware components, thereby minimizing the increase in device complexity.

AI summary
A host includes a controller configured to receive a request self-diagnostic to the host, wherein the request is for diagnostic information associated with memory allocated for an application. The controller is further configured to collect the requested diagnostic information.
