Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-functional digital TVs require manual user intervention to switch between image displays, leading to inconvenient operation and lack of automatic switching capabilities.
Innovation Solution
A display apparatus comprising a first receiver, a display unit, a controller, and a processor that selectively processes and sends video signals based on control signals, allowing automatic switching between network packet streams and external video signals, enabling the display unit to automatically switch between different video content sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual switching mode is used to determine the image displayed, then users can control the display, but the operation becomes inconvenient and lacks automatic switching capability
Solution Approach 1:
The display apparatus automatically detects the presence of external video signals and switches between network packet streams and external signals without requiring manual user intervention. The system serves itself by monitoring signal conditions and autonomously making switching decisions, thereby eliminating the need for manual operation while maintaining display control functionality.
Solution Approach 2:
The system continuously monitors the status of external video signals and uses this feedback information to automatically determine when to switch from network packet streams to external signals. The feedback mechanism enables the display apparatus to respond dynamically to signal conditions and perform automatic switching based on real-time signal presence detection.
2Adaptability or versatility
If multiple input interfaces are supported, then the display apparatus can receive various video signals, but the switching between different sources becomes complex
Solution Approach 1:
The display apparatus is designed with universal input capability to accept both network packet streams and external video signals through different interfaces. The system integrates multiple signal sources and processing paths into a unified display framework, enabling seamless multi-interface support while managing switching complexity through standardized signal detection and routing mechanisms.

AI summary
A display apparatus is provided. The display apparatus includes a first receiver, a display unit, a controller and a processor. The first receiver receives a network packet stream. The controller selectively sends one of a video signal generated by processing the network packet stream and an external video signal to the display unit for displaying the received video signal, according to a control signal. The processor determines whether the network packet stream comprises a display command. The processor sends the control signal to the controller for receiving and sending the video signal of the network packet stream to the display unit, when the network packet stream includes the display command.
