Solution Overview

Problem

Existing content playback systems face challenges in reducing communication load, particularly when users need to select between tuner and display devices, leading to increased communication and processing loads on the tuner device and network.

Innovation Solution

A renderer device with a memory unit for storing network connection information, a detector to identify connected monitor devices, and a communication unit to update and send this information to a controller device, allowing direct communication between the controller and monitor devices, thereby reducing the need for the tuner device to handle communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the tuner device handles communication between controller and display devices, then device control is achieved, but communication load on the tuner device and network increases

Engineering Contradiction:
Improvedevice controlVSAvoidcommunication load
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The patent extracts the communication function from the tuner device and assigns it directly to the display device (monitor). The display device now receives control signals directly from the controller device, eliminating the need for the tuner device to relay communications. This is achieved through direct network connectivity between the controller and display devices, reducing communication load on the tuner device and network while maintaining full control functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

2Loss of energy

If direct communication between controller and monitor devices is enabled, then communication load is reduced, but device selection and connection management becomes more complex

Engineering Contradiction:
Improvecommunication loadVSAvoidconnection management
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent implements self-service mechanisms where the display device automatically manages its own connection information and device identification. The display device stores its own network connection information and can be directly selected by the controller device without requiring the tuner device to manage connections. This automatic self-management reduces the complexity of connection management while enabling direct communication.

Inventive Principle:
Principle #25Self-service
