T-Commerce Video Frame Capture Using VBI Triggers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current television commerce systems face challenges in efficiently transmitting and storing product images, which consume significant bandwidth and storage resources, especially when presented during television broadcasts.
Innovation Solution
A method and system for capturing and digitizing video frames of products from a video signal using a VBI decoder and memory, allowing for efficient storage and display, independent of an interactive program guide, and enabling t-commerce transactions through a back channel for seamless user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If full-screen video images are transmitted for each advertised product, then product display quality is improved, but transmission bandwidth consumption increases
Solution Approach 1:
The patent extracts only the essential product information (still images and audio) from the full video signal, separating it from the main program content. This extraction approach transmits only necessary data elements rather than complete video streams, significantly reducing bandwidth consumption while preserving product presentation quality.
Solution Approach 2:
The patent segments the video content by identifying and isolating specific product-related frames during advertising segments. The system divides the continuous video stream into discrete product images that can be independently captured, stored, and transmitted, enabling efficient bandwidth utilization.
2Illumination intensity
If high-resolution product images are stored locally for t-commerce transactions, then image quality is improved, but local storage requirements increase
Solution Approach 1:
The system extracts only essential product frames from the video stream for local storage, rather than storing complete video files. This extraction of key information elements reduces storage requirements while maintaining sufficient image quality for commercial transactions.
Solution Approach 2:
The patent creates digital copies of product frames from the video signal and stores these copies locally. The copying process enables efficient storage of product information in a format optimized for t-commerce operations, reducing the need for extensive video file storage.
3Adaptability or versatility
If product images are captured during broadcast for t-commerce, then user interaction capability is improved, but system complexity increases
Solution Approach 1:
The system automatically captures product frames during broadcast segments without requiring manual intervention. The automatic frame capture and processing enables user interaction capabilities while minimizing the complexity of manual system configuration and operation.
Solution Approach 2:
The patent performs preliminary actions by pre-capturing and storing product frames during the broadcast before t-commerce transactions occur. This preliminary capture eliminates the need for complex real-time processing during user interactions, simplifying the overall system architecture.

AI summary
In one embodiment, the present invention is a t-commerce platform, which is linked to the content from a video signal that the user is currently watching. At some point during the broadcast of the content, a close-up of the product is shown. Simultaneous with this, a VBI-based trigger is added to the video signal of the broadcast. This trigger causes the television, a set-top box, or a similar device to capture in a memory, a “freeze-frame” of the image being shown. This action is transparent to the user while the video being displayed on the television is continuing normally. If the user chooses to perform an interactive “buy” transaction the saved image data is used as part of the interactive screen display.
