Tuner Error Image Generation for Multimedia Service Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital content distribution networks lack effective error reporting mechanisms, leaving users unaware when service delivery is impossible due to incompatible or bandwidth-limited conditions, as current protocols do not provide dedicated error messages.
Innovation Solution
A tuner device with a processor and memory that generates and sends customizable error images or messages to terminals, masquerading as content, to inform users of service interruptions or refusals, without requiring additional bandwidth or access network access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tuner refuses or accepts incompatible service requests, then service delivery compatibility is maintained, but user awareness of service interruption is lost
Solution Approach 1:
The patent introduces an intermediary error message mechanism that mediates between the tuner's service delivery decisions and the user's awareness. When the tuner refuses or accepts incompatible service requests, it generates error messages containing specific error codes that are transmitted to the terminal device, which then displays them to the user. This intermediary communication channel ensures users are informed of service interruptions without compromising the tuner's compatibility management.
Solution Approach 2:
The patent implements a feedback loop where the tuner provides error messages back to the terminal device when service delivery issues occur. The error messages contain error codes that indicate the specific nature of the service interruption (e.g., incompatible service, bandwidth limitation). This feedback mechanism closes the information gap, allowing users to understand why a service was interrupted while maintaining the tuner's reliability in managing service compatibility.
2Loss of information
If dedicated error messages are implemented, then user notification capability is improved, but bandwidth consumption increases
Solution Approach 1:
The patent applies local quality by making error messages optional and context-dependent. Instead of continuously transmitting error messages that would consume bandwidth, the system generates error messages only when specific service delivery issues occur (e.g., incompatible service, bandwidth limitation). The error messages are localized to specific events rather than being a continuous stream, thus providing user notification capability while minimizing unnecessary bandwidth consumption.
Solution Approach 2:
The patent changes the parameter of error message transmission from continuous to event-triggered. Error messages are generated and transmitted only when specific conditions are met (service refusal, incompatible service, bandwidth limitation). This parameter change ensures that user notification capability is maintained for actual issues while avoiding bandwidth waste from unnecessary error message transmissions during normal operation.
3Loss of information
If error messages are generated for all service scenarios, then user awareness is maximized, but system complexity increases
Solution Approach 1:
The patent segments error message generation into distinct categories based on specific service delivery scenarios (incompatible service, bandwidth limitation, service refusal). Each error type has its own error code and handling mechanism. This segmentation allows the system to provide comprehensive user awareness for different scenarios while managing complexity through structured, modular error handling rather than a monolithic error message system.
Solution Approach 2:
The patent implements partial action by generating error messages only for specific service delivery issues rather than for all possible scenarios. The system focuses on the most critical error types (incompatible service, bandwidth limitation, service refusal) and provides targeted error messages for these cases. This partial approach maximizes user awareness for the most important issues while avoiding the excessive complexity that would result from comprehensive error messaging for every possible scenario.

AI summary
In certain home multimedia networks having a plurality of terminals, there are no provisions for sending error messages when a service cannot be delivered owing to conflicts with another service. The present invention proposes to let the media server of the tuner (230) in such a network (120) provide an image bearing the message and deliver this image to the terminal (150, 155) that otherwise would be left in the dark.
