Operational Terminal Device Display Control for Remote Button Operation

The patent displays operation buttons and their corresponding instructions on the terminal device's display screen, creating a visual copy of the remote control interface. This allows the user to see button labels and instructions on the screen while physically operating the buttons on the remote control, eliminating the need to constantly reference the display screen for basic operation guidance.

The display screen acts as an intermediary between the physical button and the user's understanding of its function. By displaying the button label and instruction information on the screen simultaneously with the button operation, the system provides contextual information without requiring the user to look away from the screen or refer to separate documentation.

The terminal device is designed to display operation buttons for multiple different devices on its single display screen. The system can switch between displaying buttons for different devices (e.g., television, audio equipment, video equipment) based on which device is currently active or selected, allowing one terminal device to serve multiple functions and eliminate the need for separate remote controls for each device.

The patent combines the functionality of multiple dedicated remote controls into a single terminal device by displaying consolidated operation buttons for different devices on one screen. This merging approach allows the user to control multiple devices through one interface, reducing the total number of remote controls needed while maintaining ease of operation for each device.

The system performs preliminary action by displaying the button labels, instructions, and operational context on the display screen before the user operates the buttons. This advance provision of information allows the user to understand what each button does without needing to frequently reference the screen during operation, improving both reliability and ease of operation.

The display screen provides continuous feedback by showing the current device state, active buttons, and operational instructions in real-time. This feedback mechanism ensures the user understands the current context and button functions without needing to frequently check the screen, as the information is continuously available and updated based on the current operation state.
