Video Comment Synchronization via Time Map and Non-Relevant Frame Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video streaming systems face inefficiencies in synchronizing comments across different time frames and removing non-relevant portions of video streams, leading to misalignment and unnecessary comment synchronization.
Innovation Solution
A computer server generates a time map for video streams, identifies non-relevant time frames, and synchronizes comment timestamps by transforming localized timestamps to synchronized timestamps based on these frames, ensuring accurate synchronization and removal of irrelevant content.

Engineering Contradiction Analysis
1Productivity
If comment synchronization is performed on all video frames including non-relevant portions, then comment coverage is complete, but synchronization efficiency deteriorates and unnecessary processing occurs
Solution Approach 1:
The patent extracts and removes non-relevant time frames from the video stream before performing comment synchronization. The server identifies segments that do not contain meaningful content (such as black screens, loading indicators, or irrelevant transitions) and excludes them from the synchronization process, thereby eliminating unnecessary processing while maintaining complete comment coverage for relevant content.
Solution Approach 2:
The video stream is divided into discrete time frames and segments, with the server identifying and separating non-relevant portions from relevant content. This segmentation allows the system to apply comment synchronization selectively only to relevant segments, improving efficiency by avoiding processing of unnecessary frames while ensuring complete coverage of meaningful content.
2Measurement precision
If localized timestamps are transformed to synchronized timestamps without accounting for non-relevant frames, then transformation is simple, but timestamp accuracy deteriorates
Solution Approach 1:
The server performs preliminary identification and removal of non-relevant time frames before the timestamp transformation process. By pre-processing the video stream to eliminate irrelevant segments, the system establishes an accurate mapping between localized and synchronized timestamps only for relevant content, ensuring precision without requiring complex real-time adjustments during transformation.
Solution Approach 2:
The patent introduces an intermediary time map that serves as a reference between localized timestamps and synchronized timestamps. This time map accounts for the removal of non-relevant frames and provides an accurate conversion reference, allowing precise timestamp transformation while managing complexity through a structured intermediary layer rather than direct complex calculations.
3Productivity
If all video segments are transmitted to client devices, then video completeness is maintained, but transmission efficiency deteriorates
Solution Approach 1:
The server extracts and removes non-relevant time frames from the video stream before transmission to client devices. By identifying and eliminating segments that do not contain meaningful content (such as black screens, loading indicators, or irrelevant transitions), the system reduces transmission data volume and improves efficiency while maintaining completeness of all relevant video content that users need to view.

AI summary
In one embodiment, a computer server machine generates a time map associated with the video stream. The video stream comprises one or more time slices. The computer server machine identifies a non-relevant time frame. The computer machine receives a comment and a localized comment time stamp, and associates the comment with one or more time slices. One or more client devices communicates a request for one or more time slices to the computer server machine, and the computer server machine determines whether the localized comment time stamp is within the requested one or more time slices. When the localized comment time stamp is within the requested one or more time slices, computer server machine transforms the localized time stamp to a synchronized comment time stamp. Computer server machine sends information regarding the synchronized comment time stamp to the one or more client devices.
