Solution Overview

Problem

As digital broadcasting channels and functions increase, conventional remote controllers become cumbersome and difficult to use, hindering user convenience and efficiency in controlling digital broadcast receivers.

Innovation Solution

A dual remote controller system comprising a space remote controller and a screen remote controller, where the space remote controller communicates wirelessly with the digital broadcast receiver, and the screen remote controller, displayed on the receiver's screen, allows users to control functions by moving a cursor to specific regions, simplifying the control process and reducing the need for numerous buttons.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional remote controller is used to control digital broadcast receiver, then the basic control functions can be performed, but the increasing number of channels and functions make the remote controller cumbersome and difficult to use

Engineering Contradiction:
Improvecontrol functionsVSAvoidremote controller structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the control system into two parts: a physical remote controller for basic operations and a virtual screen remote controller displayed on the screen for additional functions. This segmentation allows the physical remote to remain simple while the screen displays complex control options, resolving the contradiction between versatility and complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent adds a new dimension to the remote control interface by displaying a virtual remote controller on the screen. This transforms the control system from a single-physical-device approach to a multi-dimensional approach combining physical and visual interfaces, enabling more functions without increasing physical complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If more buttons are added to the remote controller to handle increased channels and functions, then the adaptability improves, but the ease of operation deteriorates due to the increased number of buttons

Engineering Contradiction:
Improvechannel and function controlVSAvoiduser convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent creates a virtual copy of the remote controller interface on the screen, which can display additional buttons and controls without adding physical buttons. This copying approach maintains ease of operation by keeping the physical remote simple while providing access to more functions through the screen-based virtual remote.

Inventive Principle:
Principle #26Copying

3Device complexity

If a single remote controller is designed to handle all functions, then the device complexity is minimized, but the ease of operation worsens due to the difficulty of loading all buttons within one remote

Engineering Contradiction:
Improveremote controller configurationVSAvoidbutton accessibility
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent segments the control interface between the physical remote controller and the screen-based virtual remote controller. The physical remote maintains a simple configuration with essential buttons, while the screen displays additional virtual buttons and controls, resolving the contradiction between minimizing device complexity and maintaining ease of operation.

Inventive Principle:
Principle #1Segmentation

AI summary

A digital broadcast receiver controlled by a screen remote controller and controlling method, the method comprising: receiving broadcast signal comprising a broadcast program via a tuner; receiving IR signal from a physical remote controller via an infrared (IR) module; changing a power-off state of the television into a power-on state of the television based on the received IR signal; receiving RF signal from the physical remote controller via a radio frequency (RF) module; displaying a screen remote controller in a predetermined region while displaying the received broadcast program in a screen of the television, the screen remote controller comprising at least two control regions, the first control region being comprised of sub-regions which are used to change at least one channel of the television and the second control region being comprised of at least one sub-region which is used to perform another function different from changing the at least one channel of the television; moving a pointer's position within the screen based on the physical remote controller's movement information; changing a current channel into another channel if the pointer is located at a specific sub-region within the first control region of the screen remote controller and a specific button signal is received from the physical remote controller; and performing another function if the pointer is located at a specific sub-region within the second control region of the screen remote controller and the specific button signal is received from the physical remote controller.
