Television Peripheral Interface Association System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current television sets require users to manually search and identify peripherals by scanning interfaces, which is time-consuming and tedious, especially when multiple peripherals are connected or in standby, without providing clear associations between interfaces and their corresponding contents.
Innovation Solution
A television set with a video processing system that includes a microcontroller, GPUs, and switches to cyclically display and process video images from multiple peripherals, associating them with graphic indications of their interfaces, allowing users to identify and select desired content quickly and efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually search and identify peripherals by scanning interfaces, then users can select peripheral content, but the process is time-consuming and tedious
Solution Approach 1:
The system performs preliminary actions by automatically detecting and identifying all connected peripherals before the user needs to select content. The microcontroller scans interface terminals, identifies peripheral devices, and stores this information in advance, so when the user wants to select content, the identification work is already completed, eliminating the need for manual scanning and reducing selection time
Solution Approach 2:
The system provides feedback by displaying identified peripheral information through the video display device. The microcontroller sends identification results to the display, showing users what peripherals are connected and their status, enabling informed selection without manual interface scanning. This feedback mechanism guides users directly to available content sources
2Loss of information
If the television set displays menu options with interface names, then users can identify interfaces, but the association between interfaces and peripheral contents is not clear
Solution Approach 1:
The microcontroller acts as an intermediary that automatically establishes and manages the association between interface terminals and peripheral devices. It receives signals from interfaces, identifies connected peripherals, and maintains the mapping relationship in memory, making the association clear without requiring complex display systems or manual user configuration
Solution Approach 2:
The system performs self-service by automatically identifying peripherals and establishing interface-peripheral associations without user intervention. The microcontroller autonomously scans interfaces, detects connected devices, and updates the association information, eliminating the need for users to manually configure or track which interface corresponds to which peripheral

AI summary
A television set including: interfaces for receiving peripheral sources; a screen for displaying at least one of said sources; a graphic-indications generator for showing on said screen indications relating to said interfaces; a control unit; control means for issuing commands to said television set; a video memory for storing video images obtained by processing said peripheral sources; and a processing means for reducing the dimensions of said peripheral sources to generate said video images and associating said video images to respective graphic indications relating to said interfaces. The association result is displayed on the screen, as a general video image, to allow user to identify the interface associated with the corresponding video image. A pointing element is used to select one of said video images. In response to a command issued by said control means, the contents of said selected video image are shown on said screen in full-screen form.
