Data Image Extraction from Video Streams for Browsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video conferencing systems do not allow easy browsing, review, or distribution of data images after they have been shared, as data is encoded and transmitted within real-time video streams, making it difficult for users to access or re-examine previously presented content.
Innovation Solution
Systems and methods for identifying and selecting data images within a video stream, using processors to receive and decode video bit streams, identify sets of data images, and select the best representation of data images, enabling efficient extraction and storage of key data frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data is encoded and transmitted within real-time video streams, then data can be shared between remote participants, but users cannot easily browse, review, or distribute data images after they have been shared
Solution Approach 1:
The patent segments the video stream into individual data images by identifying and extracting specific frames that contain data. This allows the data to be separated from the continuous video stream, enabling users to browse, review, and distribute individual data images independently without retransmitting the entire video stream.
Solution Approach 2:
The patent extracts data images from the video stream by identifying frames that contain data and separating them from the rest of the video content. This extraction process enables users to access, review, and distribute the data images on demand, transforming the data from a transient part of the video stream into a reusable resource.
2Speed
If data is transmitted as part of a continuous video stream, then real-time communication is enabled, but previously presented data cannot be easily accessed by late arrivals
Solution Approach 1:
The patent performs preliminary action by extracting and storing data images from the video stream as they are transmitted. This allows users who arrive late to access the data images immediately from the stored copies, eliminating the need to wait for the entire video stream to be retransmitted or for data to be sent again.
3Loss of information
If the entire video stream is retransmitted to allow browsing of data images, then complete data availability is achieved, but transmission time and bandwidth consumption increase
Solution Approach 1:
The patent extracts only the necessary data images from the video stream and stores them separately. When users need to access data, only the extracted data images are transmitted, not the entire video stream. This significantly reduces transmission time and bandwidth consumption while maintaining complete data availability.
Solution Approach 2:
The patent creates copies of data images by extracting them from the video stream and storing them in a database or memory structure. Users can access these copies directly without requesting the original video stream, enabling rapid retrieval and reducing the need for retransmission of the complete video stream.
