Display Playback Control Using Noise Event Time Markers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face difficulties in allowing users to easily revisit missed content due to noise interference, with prior solutions failing to address this issue effectively.
Innovation Solution
A display device and method that includes a memory, an interface, and a controller configured to detect noise events, store event occurrence timing points, and allow users to replay missed content based on control signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If noise occurs during content playback, then audio quality deteriorates, but the user cannot easily revisit missed content
Solution Approach 1:
The system performs preliminary actions by detecting noise events and automatically storing timing points during content playback before the user needs to revisit content. This proactive approach captures the exact moment when noise interrupted the user, eliminating the need for manual searching or remembering where to resume playback.
Solution Approach 2:
The system implements feedback by providing users with an event occurrence list that shows detected noise events and their timing points. This feedback mechanism allows users to see what was missed and selectively replay specific segments, creating a closed-loop system that responds to user needs based on actual playback interruptions.
2Reliability
If the system continuously monitors for noise events, then content playback reliability improves, but device complexity increases
Solution Approach 1:
The controller leverages the existing microphone or noise detection capability of the display device for multiple purposes: both for its original function (audio input/voice commands) and for detecting noise events during content playback. This multi-functionality approach allows noise monitoring without adding dedicated hardware, thereby reducing overall device complexity while maintaining reliability.
Solution Approach 2:
The system performs self-service by automatically detecting noise events, storing timing points, and generating event occurrence lists without requiring external assistance or complex additional components. The controller utilizes existing device resources (microphone, memory, processor) to autonomously manage the noise detection and content replay functionality.

AI summary
Provided in one embodiment of the present disclosure is a display device comprising: a memory; an interface unit for communicating with an external device; a display for outputting content; and a control unit for controlling a communication unit and the display, wherein the control unit detects the occurrence of an event while the content is being output, stores the point in time at which the event is detected, outputs an event occurrence list in response to receiving a first control signal, and plays back first content of a first time point on the basis of a second control signal for selecting the first event included in the event occurrence list.
