Video Segmentation via Comment Timestamps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video hosting services require users to manually seek to specific time offsets in videos, which can be inconvenient due to the need to wait for the entire video to load and remember the offset, leading to potential missed content.
Innovation Solution
The system segments videos based on user-provided timestamps, creating an index that allows prefetching of video segments, enabling immediate playback of specified segments without loading the entire video.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the system loads the entire video into the video player, then the user can access any time offset in the video, but the loading time becomes relatively long
Solution Approach 1:
The patent divides the video into multiple segments based on timestamps extracted from comments. Each segment corresponds to a specific time range in the video and can be independently loaded and played. This segmentation allows the system to load only the necessary video portion rather than the entire video, thereby reducing loading time while maintaining ease of access to specific content.
Solution Approach 2:
The system performs preliminary actions by pre-processing the video into segments and pre-loading them into the video player before the user requests specific content. The timestamps from comments are parsed and used to identify and load the relevant video segments in advance, so when the user clicks on a comment, the corresponding segment is already ready for immediate playback.
2Ease of operation
If the user manually controls the video player to seek to the suggested time offset, then the user can view the specific video content, but the user must remember the time offset while waiting for the video to load
Solution Approach 1:
The system performs self-service by automatically managing the video loading process. When a user submits a comment with a timestamp, the system parses the timestamp, identifies the corresponding video segment, and automatically loads it into the video player. The user does not need to manually seek or remember time offsets; the system handles the entire process autonomously based on the comment information.
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of a comment-based timestamp system. Comments serve as intermediaries that contain embedded timestamps, which the system parses and uses to automatically navigate to the relevant video segments. This intermediary layer eliminates the need for direct user interaction with the video player's seek controls and removes the memory burden of remembering time offsets.
3Loss of time
If some users choose to forgo viewing the suggested video content, then they can avoid waiting for the entire video to load, but they lose the opportunity to view potentially valuable content
Solution Approach 1:
By segmenting the video based on comment timestamps, the system makes specific content reliably accessible without requiring the entire video to load. Each segment can be independently loaded and played, ensuring that users can reliably access the content they need (indicated by comments) while avoiding unnecessary waiting time for unrelated portions of the video.
Data Source
AI summary
A system, method, and computer program product are provided for segmenting videos in a video hosting service. To determine segments related to timestamps, user generated comments are parsed for timestamps. The timestamps are organized into sets and a segment is identified for each set of timestamps. A start point for each segment is determined based on the timestamps in each set. The segment will have an endpoint that can be either the end of the itself, or optionally can be determined based on the timestamps. Each timestamp is associated with a segment. One or more indicators represent each timestamp and each indicator is coupled to the segment associated with timestamp represented by the indicator. The segments are ranked according to popularity or the submission time of their related timestamp indicators. Responsive to receiving a client request for a video, the comments, indicators, and segments are loaded to the client.
