Solution Overview

Problem

Conventional technologies for displaying a PC screen on a television apparatus via wireless communication require users to manually select the connection destination, leading to potential wrong selections and increased operational load due to the need to put the television apparatus into a waiting state for each connection.

Innovation Solution

A television apparatus and display control method that includes a receiving module, display controller, obtaining module, storage module, and controller to display identification information, generate and verify security information, and store external-device identification, allowing secure connection without requiring the television apparatus to be put into a waiting state for subsequent connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a television apparatus requires manual selection from multiple devices to establish connection, then connection accuracy is improved, but user operational load increases

Engineering Contradiction:
Improveconnection accuracyVSAvoiduser operational load
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The television apparatus automatically identifies and connects to the PC that has issued a connection request, eliminating the need for manual selection. The system uses its own identification information to authenticate the connection request and establish communication automatically, making the device serve itself in the connection process.

Inventive Principle:
Principle #25Self-service

2Reliability

If the television apparatus is put into waiting state for each connection, then connection security is improved, but operational complexity increases

Engineering Contradiction:
Improveconnection securityVSAvoidoperational complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The television apparatus transmits its identification information to the PC in advance as registration information. This preliminary action allows the PC to store the television's identification, enabling automatic authentication in subsequent connections without requiring the television to enter a waiting state, thus reducing operational complexity while maintaining security.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If automatic connection is enabled without waiting state, then ease of operation is improved, but connection security deteriorates

Engineering Contradiction:
Improveease of operationVSAvoidconnection security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system uses feedback through identification information exchange and verification. The television transmits its identification to the PC, and when a connection request is received, the television verifies whether the requesting PC has previously registered its identification. This feedback mechanism ensures secure automatic connection by confirming the legitimacy of the connection request based on prior registration.

Inventive Principle:
Principle #23Feedback

AI summary

According to one embodiment, a television apparatus includes a receiving module, a display controller, a receiving controller, an obtaining module, a storage module, and a controller. The receiving module receives an operation for putting the television apparatus into a waiting state to connect to an external device. The display controller displays identification information identifying the television apparatus, security information generated randomly, and displays screen information received from the external device. The receiving controller receives the request for connection and the security information. The obtaining module obtains external-device identification information identifying the external device if communication with the external device is initiated. The storage module stores the external-device identification information. The controller controls the display controller to display the screen information without putting the television apparatus into the waiting state if a request for communication is received from the external device.
