Light Code Video Overlay for Product Information Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Viewers cannot easily obtain detailed information about products or objects shown in videos without disrupting the normal viewing experience.
Innovation Solution
A system and method that combines light codes with videos, where an editing device identifies candidate objects and matches them with light code symbols to create a light code output table, allowing viewers to scan and retrieve information using a user device, which is then looked up by a server to provide relevant product or object details.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional display devices are used to show videos, then video playback is normal and clear, but viewers cannot easily obtain detailed information about products or objects shown in the video
Solution Approach 1:
The patent introduces light codes as an intermediary element that bridges the video content and product information. The light codes are embedded in the video frames and can be scanned by user devices to retrieve detailed product information, serving as a mediator between the visual content and the information database without disrupting the video playback experience
Solution Approach 2:
The system performs preliminary action by pre-generating light codes for all candidate objects in the video during the video production phase. The editing device identifies candidate objects and generates corresponding light codes that are then embedded in the video frames, so that when viewers watch the video, the information retrieval mechanism is already in place and ready for immediate use
2Loss of information
If light codes are embedded in video frames, then viewers can access additional information, but the video playback experience may be affected
Solution Approach 1:
The patent applies local quality by selectively embedding light codes only in specific regions of video frames where they do not interfere with the main content. The system identifies appropriate locations within frames to place light codes, ensuring that the video quality and viewing experience are maintained while still providing information access functionality
Solution Approach 2:
The system uses partial action by not embedding light codes in every frame or every region of the video, but only in selected frames and specific locations where candidate objects are present. This selective approach minimizes the impact on video playback quality while still providing effective information access when needed

AI summary
A system and method for combining light codes and a video are provided. The system includes an editing device and a storage device. The editing device identifies the content of a video to obtain a playback period of a plurality of frames having at least one candidate object in the video. The storage device stores at least one candidate object code and at least one light code symbol, and the light code symbol has a correspondence with the candidate object code. The editing device matches playback period of the frames having the at least one candidate object with the light code symbol, so as to provide a light code output table corresponding to the video.
