Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Pay TV set top boxes consume excessive power, particularly in standby modes, leading to high national energy demands, as they often remain in active standby mode for extended periods, consuming more power than necessary.

Innovation Solution

A control method that optimizes the shift between active and passive standby modes through network cooperation between pay TV networks and set top boxes, using a power management server to monitor and manage operation statuses, shifting modes based on usage patterns and timer settings to minimize power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the set top box remains in active standby mode to perform background functions (protocol processing, EPG updates), then service responsiveness is improved, but power consumption increases

Engineering Contradiction:

Improveservice responsivenessVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system dynamically transitions between active standby mode and passive standby mode based on service requirements and user behavior patterns. The set top box adjusts its operational state in real-time, switching to passive mode when no services are needed and returning to active mode when services are required, thereby optimizing the balance between service responsiveness and power consumption

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The set top box autonomously determines when to switch between active and passive standby modes by monitoring service requests and user behavior patterns. The system self-manages its power state without requiring manual user intervention, automatically transitioning to low-power mode when appropriate and returning to full functionality when needed

Inventive Principle:

Principle #25Self-service

2Use of energy by moving object

If the set top box frequently switches between active and passive standby modes, then power consumption is reduced, but system stability deteriorates

Engineering Contradiction:

Improvepower consumptionVSAvoidsystem stability

Core Design Contradiction:

Use of energy by moving objectVSStability of the object's composition

Solution Approach 1:

The system performs preliminary analysis of user behavior patterns and service requirements before making mode transition decisions. By predicting future service needs based on historical data and current context, the system avoids unnecessary mode switches and ensures stable operation while still achieving power savings through informed transitions

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors service requests, user behavior patterns, and system state to provide feedback for mode transition decisions. This closed-loop control ensures that transitions are made only when appropriate, maintaining system stability while optimizing power consumption through data-driven decisions

Inventive Principle:

Principle #23Feedback

3Use of energy by moving object

If the set top box enters passive standby mode to minimize power consumption, then energy usage is reduced, but service responsiveness deteriorates

Engineering Contradiction:

Improvepower consumptionVSAvoidservice response time

Core Design Contradiction:

Use of energy by moving objectVSLoss of time

Solution Approach 1:

The system predicts future service needs based on user behavior patterns and pre-loads or pre-prepares necessary data and resources while in passive standby mode. This allows the system to quickly transition to active mode and resume services without significant delay, reducing the effective service response time while maintaining power savings

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts the duration and depth of passive standby mode based on predicted service requirements. When services are likely to be needed soon, the system maintains a lighter standby state with minimal processing. When services are unlikely to be needed, the system enters deeper power-saving mode, optimizing the trade-off between power consumption and service response time

Inventive Principle:

Principle #15Dynamics

AI summary

A network cooperation-based low power type charged broadcasting set-top box and a controlling method therefor, the set-top box sub-dividing a standby mode of the set-top box into an active standby mode, in which only background functions are processed without processing a main function, and a passive standby mode, in which no functions are processed; extending the passive standby mode occupation time to more than that of the active standby mode; and including a way of transitioning between operating modes by exchanging information regarding the set-top box through an inter-cooperation between a charged broadcasting network and the set-top box, thereby reducing the power consumption of a processor (SoC) which processes multimedia contents and minimizing the power consumption while the set-top box is in standby mode.
