Video Node Location via Subtitle Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inefficiencies in locating specific content within videos due to the lack of accurate and time-saving methods for navigating through rich content videos, such as knowledge or popular science videos, which require repeated viewing, as existing methods like fast-forwarding or previewing frames are not precise enough.
Innovation Solution
A method and apparatus that select a target video based on value measurement, display subtitle text segments with start time information, and allow users to determine a start playing node by triggering a specific subtitle text segment, thereby saving computing resources and improving interaction efficiency between the server and client.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users use fast-forwarding or previewing frames to locate specific content in videos, then users can navigate through videos, but the locating precision is insufficient and time-consuming
Solution Approach 1:
The patent segments the video content by extracting subtitle text and dividing it into multiple text segments, each associated with specific time information. This segmentation allows users to locate specific content by searching through discrete text segments rather than continuously scanning video frames, significantly improving locating precision and reducing time consumption.
2Measurement precision
If the system processes and analyzes all video content to enable precise locating, then locating accuracy improves, but computing resources are consumed
Solution Approach 1:
The patent extracts only the essential subtitle text from the video content, separating this key information from the full video data. By processing and indexing only the extracted text segments rather than the entire video, the system achieves accurate content locating while significantly reducing computing resource consumption.
3Productivity
If the system displays full subtitle text to help users locate content, then users can find specific information faster, but interaction complexity increases
Solution Approach 1:
The patent applies local quality by displaying different portions of subtitle text with different visual characteristics. Specific text segments corresponding to searchable content are highlighted or distinguished from other parts, allowing users to quickly identify relevant content without being overwhelmed by the full subtitle text, thus improving content finding speed while maintaining simple interaction.

AI summary
The disclosure provides a method for locating a video playing node, and relates to fields of big data and video processing. The method includes: selecting a target video out from a plurality of videos; and sending the target video, a plurality of subtitle text segments of the target video and start time information of each of the plurality of subtitle text segments to a client, to cause the client to display the plurality of subtitle text segments, and determine, in response to a trigger operation on an any subtitle text segment of the plurality of subtitle text segments, a start playing node of the target video based on the start time information of the any subtitle text segment. The disclosure further provides an apparatus for locating a video playing node, an electronic device and a storage medium.
