Dual-Channel Interface for Game Console Television Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing information processing systems, where a game console and a television receiver are connected, suffer from functional limitations and other issues due to a one-sided data output configuration, limiting user input and control capabilities.
Innovation Solution
A game console with a data-sending interface for multimedia data transmission and a request-sending interface to control the television receiver, allowing for event detection and sending requests with control information to instruct the television receiver on user interface guidance and control operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a one-sided data output configuration is used where the information processing apparatus outputs data to the television receiver, then the system structure is simple, but the functional limitations increase and user control capabilities are reduced
Solution Approach 1:
The patent divides the communication interface into two separate transmission channels: a first transmission channel for data output from the information processing apparatus to the television receiver, and a second transmission channel for control input from the information processing apparatus to the television receiver. This segmentation allows the system to maintain simple data output while adding bidirectional control capabilities through the separate control channel.
Solution Approach 2:
The information processing apparatus is equipped with dual-interface capability: it can function as both a data output device (through the first transmission channel) and a control device (through the second transmission channel). This multi-functionality allows the same apparatus to both send multimedia data and send control commands, eliminating the need for separate control devices and reducing overall system complexity while enhancing control capabilities.
2Device complexity
If the television receiver performs one-sided input switching control, then the control logic is simple, but the ease of operation for users decreases
Solution Approach 1:
The patent implements a feedback mechanism where the information processing apparatus can detect user inputs through the second transmission channel and send control commands back to the television receiver. This allows the system to respond to user actions and adjust input switching dynamically, providing bidirectional interaction while maintaining simple control logic through automated feedback loops.
Solution Approach 2:
The information processing apparatus automatically detects user inputs and generates appropriate control commands without requiring separate control logic in the television receiver. The system serves itself by autonomously processing user inputs and managing input switching, reducing the control burden on the television receiver while enhancing user operation ease.
