Video Preview Window for Accurate Content Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of video recordings or video streams on electronic devices lack an accurate method to locate specific portions, relying on still images or manual navigation, which is inefficient for finding desired content.
Innovation Solution
A system and method that allows users to select a time within a video recording or stream to preview a portion of it in a second viewing window, providing a more accurate and efficient way to locate specific parts by displaying a preview corresponding to the selected time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a user places a cursor over the time bar to preview a still image, then the user can view a snapshot of a specific portion, but the user cannot know with certainty whether the still image corresponds to the desired location
Solution Approach 1:
The patent creates a copy of the video content at the selected time point and displays it in a preview window. Instead of showing only a still image, the system generates a playable video segment that replicates the content at the desired location, allowing users to verify the actual content before navigating to it.
Solution Approach 2:
The patent divides the video playback experience into two separate windows: the main video window and a preview window. This segmentation allows the user to simultaneously view the current playback position and a preview of the selected portion, enabling accurate location verification without losing information about either view.
2Loss of time
If a user views the recording until the desired portion appears or uses forward/rewind buttons, then the user can locate specific parts, but the process is time-consuming and inefficient
Solution Approach 1:
The patent allows users to perform preliminary actions by selecting a time point on the time bar before actually navigating to that portion. The system prepares and displays a preview of the selected content in advance, so when the user decides to navigate, the content is already verified and ready, eliminating the need for time-consuming forward/rewind operations.
Solution Approach 2:
The preview window serves as an intermediary between the time bar selection and the main video playback. Instead of directly jumping to the selected time point, the system introduces a preview step that mediates the navigation process, allowing users to verify content before full navigation, thus improving efficiency by preventing incorrect jumps.
3Reliability
If a user relies on still images to locate portions, then the interface is simple, but the user cannot accurately determine whether the image corresponds to the desired content
Solution Approach 1:
The patent transitions from a one-dimensional still image preview to a two-dimensional solution by adding a separate preview window that displays actual video content. This dimensional change from static image to dynamic video preview in a separate space allows accurate content identification while maintaining interface organization through spatial separation.

AI summary
Certain aspects of the present disclosure relate to methods and systems for previewing a recording. In one aspect, the methods and systems are configured to display a video recording/stream in a first viewing window on a display, receive a selection of a time within the video recording/stream at which to preview a portion of the video recording/stream, display a second viewing window on the display, and display the preview of the portion of the video recording/stream that corresponds to the selection within the second viewing window.
