Live Video Tagging with Delayed Stream Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In live video tagging, continuous scenes often fail to be tagged correctly, leading to inefficiencies as the video cannot be rewound to re-tag missed scenes, requiring time to re-produce and re-search the video for retagging.
Innovation Solution
An information processing apparatus and method that displays a live video alongside a delayed version of the same video, allowing users to input tags in real-time and correct or re-input tags on the delayed video, facilitating easy tagging by synchronizing tag inputs with the correct timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If tagging is performed on live video in real-time, then tagging speed is improved, but tagging accuracy deteriorates due to continuous scenes causing tag failures
Solution Approach 1:
The system performs preliminary tagging on the delayed video after the live video has been processed. This allows the tagging operation to be executed with sufficient time for review and correction, ensuring accuracy while maintaining real-time processing capability for the live stream.
Solution Approach 2:
A delayed video stream is introduced as an intermediary between the live video input and the final tagged output. This intermediary allows the tagging system to review and correct tags before they are finalized, resolving the contradiction between speed and accuracy by providing a buffer for quality control.
2Reliability
If tagging fails on continuous scenes, then tagging reliability deteriorates, but time loss increases due to inability to rewind and re-tag
Solution Approach 1:
The delayed video provides a time buffer that allows failed tags to be corrected in the delay period before the video is finalized. This preliminary correction opportunity eliminates the need for time-consuming rewinding and re-searching, as all corrections can be made while the video is still in the delayed state.
Solution Approach 2:
The system builds in a time cushion through the delayed video stream, creating a safety margin that accommodates tagging failures. This beforehand cushioning ensures that even if tagging fails on continuous scenes, there is sufficient time to correct errors without requiring video rewinding or causing production delays.
3Measurement precision
If a delayed video is displayed alongside live video, then tagging accuracy is improved through correction opportunities, but device complexity increases
Solution Approach 1:
The delayed video stream serves multiple functions: it acts as a review buffer for tag correction, provides a backup for failed tags, and enables quality control without requiring separate complex systems. This multi-functionality reduces overall system complexity while maintaining high tagging precision.
Solution Approach 2:
Instead of creating entirely separate tagging systems for live and delayed videos, the system uses a simplified copy of the video stream with the same tagging interface. This copying approach allows tag correction on the delayed stream using the same tools as the live stream, reducing complexity while improving precision.
