Time-Shifted Playback Summary for Live Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing time-shifted audio/video playback systems cause users to miss important events during pauses, as they resume playback with a delay, which is particularly disadvantageous for real-time events like sporting events.
Innovation Solution
A device and method that creates a summary of important audio/video data during pauses, allowing users to quickly catch up on missed moments by displaying this summary before resuming real-time playback, using means to store, record, and display audio/video data, and analyzing audio and video components to identify key moments for inclusion in the summary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user pauses the display of audio/video data while continuing to record it, then the user can take a break from watching, but the user misses important events that occur during the pause time
Solution Approach 1:
The system performs preliminary action by automatically creating a summary of the audio/video content during the pause period before the user resumes playback. This summary captures key moments and events that occurred while the user was away, preparing the information in advance so that when playback resumes, the user can quickly catch up on missed content without having to watch the entire paused segment from the beginning.
2Duration of action of stationary object
If the user resumes playback after a pause, then the user continues watching the programme, but the user experiences a delay relative to the live transmission
Solution Approach 1:
The system extracts and separates the summary content from the full audio/video stream. When the user resumes playback after a pause, the system plays back only the extracted summary portion first, which condenses the key events from the pause period into a shorter format. This extraction approach allows the user to quickly catch up on essential content and reduces the overall time delay compared to watching the entire paused segment at normal speed.
3Loss of information
If the system displays the complete audio/video data received during pause time, then the user sees all events, but the user spends too much time catching up and loses real-time viewing benefit
Solution Approach 1:
The system segments the audio/video content into two distinct parts: the full original content and an automatically generated summary. During pause periods, the system creates a condensed summary version that highlights key moments and events. When playback resumes, the user can choose to view the summary segment first to quickly catch up on essential content, or proceed directly to the live stream. This segmentation allows users to balance between seeing complete events and minimizing catch-up time.
