Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control systems for television receivers fail to provide information from external devices, such as hard disk recorders, when a terrestrial broadcast signal is being viewed, and cannot inform users of connection failures or abnormalities, limiting user interaction and feedback.
Innovation Solution
A display control apparatus with wireless communication capabilities that generates and outputs video/audio signals, selects signal patterns to control the display, and informs users of information related to the selected signals, allowing for voice output and storage of multiple information pieces based on signal patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the television receiver displays video/audio from its embedded tuner, then the display function is fulfilled, but information from external devices cannot be informed to the user
Solution Approach 1:
The patent introduces a remote control device as an intermediary that receives control signals and provides feedback information to the user. When the television displays content from its embedded tuner, the remote control device can still receive signals from external devices and inform the user about their status, connection states, and available content through its display and output interfaces.
Solution Approach 2:
The patent divides the information delivery function into two separate components: the television receiver handles primary video/audio display, while the remote control device handles information notification and feedback. This segmentation allows both functions to operate simultaneously without interfering with each other, enabling the user to view broadcast content while receiving information about external devices.
2Extent of automation
If the television receiver is used for remote control operations, then device control is achieved, but user feedback and information provision are limited
Solution Approach 1:
The remote control device is designed with multi-functionality: it can both control the television receiver (sending control signals) and provide information feedback to the user (displaying status, connection states, and content information). This universal design allows a single device to fulfill both control and information provision roles simultaneously.
Solution Approach 2:
The patent implements a feedback mechanism where the remote control device receives information from external devices and the television receiver, processes it, and provides real-time feedback to the user through its display and output interfaces. This feedback loop enables users to understand the status of remote control operations and external device connections.
3Reliability
If the system relies on the television receiver for all information output, then device complexity is reduced, but reliability of information delivery decreases
Solution Approach 1:
The patent prepares for potential failures by implementing a backup information delivery path. The remote control device is pre-configured to receive and display information from external devices independently of the television receiver's display function. If the television receiver fails to deliver information (due to connection issues or display problems), the remote control device serves as a backup information source, ensuring reliable information delivery.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables user interaction and feedback by providing information corresponding to selected video/audio signals, ensuring user awareness of display states and remote control functionality, even when external devices are not properly connected or when terrestrial broadcasts are being viewed.
Implementation Method 1
a transmission unit configured to transmit a signal to the television receiver and an external device in accordance with the selected signal pattern, and a reception unit configured to receive a signal from the television receiver and the external device
Data Source
AI summary
A display control apparatus connected to a display apparatus, which is remotely controllable through wireless communication, generates a first video/audio signal for displaying a first image on the display apparatus, and outputs the first video/audio signal to the display apparatus. Either of a first signal pattern indicative of a command to cause the first image based on the first video/audio signal to be displayed on the display apparatus or a second signal pattern indicative of a command to cause a second image based on a second video/audio signal, which is obtained from a device different from the display control apparatus, to be displayed on the display apparatus is selected, and a wireless signal of the selected signal pattern is outputted to the display apparatus through the wireless communication. Information determined based on the signal pattern of the outputted wireless signal is informed from an apparatus different from the display apparatus.
