Display Control Device for Dynamic Input Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control systems cannot effectively control input switching of display devices based on the state of connected information processing devices, leading to inefficient user interactions.
Innovation Solution
A display control device and system that includes a storage unit for device and reception status information, a determination unit to interpret user instructions, and a command generation unit to issue commands to the display device and connected information processing devices, allowing for dynamic switching based on the state of these devices.

1Ease of operation
If the broadcast receiving device activates an input terminal to which an external input device corresponding to a call word is connected, then the display device can show the expected content, but it cannot control input switching according to the state of the external input device
Solution Approach 1:
The control device acquires state information from external input devices (such as whether a disc is loaded in a DVD player or if a game is running in a game console) and uses this feedback to intelligently determine whether switching to that device is appropriate, rather than simply responding to voice commands without context
Solution Approach 2:
The system pre-acquires state information from multiple external input devices and stores it before receiving user commands, so that when a voice command is received, the switching determination can be made immediately based on already-available state data, improving response speed and user experience

AI summary
A display control device controls a display device. The display device includes two or more input units to which information processing devices are connected. The display control device includes a storage unit, a determination unit, and a command generation unit. The storage unit stores device information and reception status information. The device information indicates a state of each of the information processing devices. The reception status information indicates one of the information processing devices, which outputs a display image displayed by the display device. The determination unit determines a content of an instruction from an user. The command generation unit generates a command to be issued to at least one of the display device and the information processing devices based on a determination result of the determination unit and the information stored in the storage unit.
