External Peripheral Device for Smart TV Feature Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional TVs lack the ability to display enhanced features such as playing videos, receiving and executing game images, or retrieving and displaying real-time information from the Internet, limiting their functionality for several years after purchase.
Innovation Solution
A display apparatus that combines video and graphic signals using an external peripheral device, allowing for the display of graphic information associated with video content, with features like transparency processing and user-controlled signal output through USB and HDMI interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional TV is used, then the device structure remains simple and cost-effective, but the functionality is limited and cannot support new features for several years
Solution Approach 1:
The system is divided into two independent parts: the existing display apparatus (TV) and an external peripheral device. The peripheral device handles advanced processing functions (video playback, network connectivity, graphic processing) while the TV focuses on display. This segmentation allows the TV to remain simple while gaining enhanced functionality through the external device connected via USB/HDMI interfaces.
Solution Approach 2:
An external peripheral device acts as an intermediary between the user and the display apparatus. This intermediary provides smart TV features (video playback, network access, graphic signal processing) without requiring modifications to the TV itself. The peripheral device receives control signals from the TV controller and processes them to generate enhanced output.
2Adaptability or versatility
If the display apparatus is replaced with a new device to access upgraded features, then the functionality is improved, but the cost increases and the original device becomes obsolete
Solution Approach 1:
The external peripheral device is designed to be universally compatible with multiple display apparatuses through standard interfaces (USB, HDMI). It provides multiple functions including video signal processing, graphic signal generation, network connectivity, and media playback. This multi-functionality allows a single peripheral device to replace what would otherwise require multiple specialized devices or a complete TV replacement.
3Adaptability or versatility
If the display apparatus processes all functions internally, then the system is self-sufficient, but the device complexity and cost increase
Solution Approach 1:
Complex processing functions are extracted from the display apparatus and placed in the external peripheral device. The peripheral device handles video decoding, graphic signal processing, network communication, and media playback tasks. The TV controller maintains a simplified role by generating control signals and displaying output, reducing its complexity while the system as a whole gains enhanced capabilities.

AI summary
A display apparatus includes a display which displays an image; an external peripheral device; a peripheral device interface connected to the external peripheral device; an image composing module which combines a video signal with a graphic signal and outputs a combined signal to the display; and a controller which outputs a graphic signal to the image composing module when the graphic signal is input from the external peripheral device through the peripheral device interface, the graphic signal being associated with contents of a video signal displayed on the display and displayed along with the video signal.
