Solution Overview

Problem

In hybrid video systems, multimedia processing apparatuses, such as PVR STBs, enter standby mode to conserve energy, but this prevents them from automatically resuming tasks and reduces system efficiency, as they cannot wake up to execute remote recording tasks or play recorded content.

Innovation Solution

Implementing a Wake-on-LAN function in PVR STBs and OTT clients, allowing them to wake up via network messages, enabling remote task execution even in standby mode by communicating with a multimedia processing server to manage standby states and adjust wake times to prevent server overload.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the PVR STB enters standby mode to save energy, then energy consumption is reduced, but the device cannot automatically wake up to execute remote recording tasks

Engineering Contradiction:
Improveenergy consumptionVSAvoidtask execution reliability
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The system performs preliminary actions by having the multimedia processing server store wake-up information and task information before the STB enters standby mode. The wake-up information includes wake-up time and wake-up conditions, allowing the STB to be activated at the appropriate moment without remaining continuously powered on, thus saving energy while ensuring task execution reliability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The multimedia processing server acts as an intermediary between the user and the STB. It receives recording tasks from users, determines whether the STB is in standby mode, and manages the wake-up process by sending wake-up messages to the STB based on stored wake-up information, enabling indirect control that resolves the contradiction between energy saving and task execution.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Use of energy by moving object

If the PVR STB enters standby mode, then energy consumption is reduced, but system utilization and efficiency are greatly lowered

Engineering Contradiction:
Improveenergy consumptionVSAvoidsystem utilization
Core Design Contradiction:
Use of energy by moving objectVSProductivity

Solution Approach 1:

The system dynamically adjusts the STB's operational state based on task requirements. The STB can transition between standby mode (for energy saving) and active mode (for task execution) depending on wake-up conditions, creating a dynamic system that optimizes both energy consumption and productivity rather than maintaining a fixed state.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements feedback mechanisms where the STB reports its operational status to the multimedia processing server. The server uses this feedback to determine whether to send wake-up messages, creating a closed-loop control system that balances energy saving with maintaining system utilization through responsive task execution.

Inventive Principle:
Principle #23Feedback

3Use of energy by moving object

If the PVR STB remains in standby mode, then energy consumption is reduced, but remote recording tasks cannot be executed

Engineering Contradiction:
Improveenergy consumptionVSAvoidremote task execution
Core Design Contradiction:
Use of energy by moving objectVSEase of operation

Solution Approach 1:

The system performs preliminary actions by pre-storing wake-up information and task information in the multimedia processing server before the STB enters standby mode. This preparation ensures that when remote recording tasks need to be executed, the STB can be quickly activated without manual intervention, maintaining ease of operation while preserving energy savings.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The STB is configured with automatic wake-up capabilities based on pre-stored wake-up information, allowing it to self-activate when specific conditions are met without requiring user intervention. This self-service mechanism maintains ease of operation for remote tasks while keeping the STB in energy-saving standby mode during idle periods.

Inventive Principle:
Principle #25Self-service
