TV Channel Registration Logic for Temporary Signal Loss

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing devices fail to distinguish between permanent and temporary reasons for a channel becoming non-selectable, leading to inappropriate channel registration management due to incorrect handling of channels that are temporarily or permanently unavailable.

Innovation Solution

Implement a counter system to track the number of consecutive times a channel is non-selectable, with a threshold value to differentiate between temporary and permanent causes, allowing for appropriate channel registration management by deleting channels permanently non-selectable and notifying users of potential reception issues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a channel that was selectable in the past is maintained as selectable without verification, then user convenience is preserved, but incorrect channel registration occurs when the channel is permanently unavailable

Engineering Contradiction:

Improveuser convenienceVSAvoidchannel registration accuracy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary verification by checking channel selectability before maintaining registration. A counter is incremented each time a channel is found non-selectable, and when the counter reaches a threshold, the channel is automatically deregistered. This preliminary action prevents incorrect channel registration while preserving user convenience for temporarily unavailable channels.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If channel selectability is strictly verified on each scan, then channel registration accuracy is improved, but temporary unavailability causes unnecessary channel loss

Engineering Contradiction:

Improvechannel registration accuracyVSAvoidhandling of temporary unavailability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts channel registration status based on the counter value. Instead of a static verification approach, the counter allows the system to adapt its response: channels with low counter values (temporary issues) are maintained, while channels with high counter values (permanent issues) are deregistered. This dynamic approach handles both temporary and permanent unavailability appropriately.

Inventive Principle:

Principle #15Dynamics

3Reliability

If a counter system with threshold is implemented to distinguish permanent from temporary unavailability, then channel management accuracy is improved, but device complexity increases

Engineering Contradiction:

Improvechannel management accuracyVSAvoidsystem structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system segments the channel management process into distinct functional units: a determination unit that checks channel selectability, a counter management unit that tracks non-selectable occurrences, and a registration control unit that decides whether to maintain or deregister channels. This segmentation improves manageability and reduces effective complexity while maintaining high accuracy.

Principle #1Segmentation

AI summary

An information processing device comprises a channel selection determiner that performs determination as to whether or not a channel is selectable; an incrementer that, in a case where a channel, on which the determination is made, is not selectable, increments a counter of the channel determined not to be selectable; and a determiner that, in a case where the counter exceeds a threshold value, determines that a channel, for which the counter exceeds the threshold value, is not receivable.
