Video Metadata Extraction via Wireless Link to Processing Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The video production process lacks efficient methods for creating and associating metadata with recorded video content in real-time, leading to inaccurate or missing information, as video cameras typically do not have the processing power to analyze media for metadata during filming, resulting in delayed and incomplete metadata availability.
Innovation Solution
A system and method that involves sending raw video media data from a video recording device to a processing device, such as a laptop, for metadata extraction and association, using wireless data exchange, where metadata like camera settings, environmental data, and content information is derived and embedded back into the video file for timely use in the production process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If video cameras are equipped with processing power to analyze recorded content for metadata during filming, then metadata availability timing is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the metadata processing function from the video camera and relocates it to a separate computer system. The camera captures video content and transmits it to the computer, which then performs the metadata extraction and analysis. This separation allows the camera to remain simple while the computer handles the complex processing tasks, resolving the contradiction between timely metadata availability and device complexity.
2Productivity
If metadata is created manually after media creation, then device complexity is minimized, but productivity and accuracy of metadata are reduced
Solution Approach 1:
The system enables self-service metadata creation by automatically extracting metadata from the video content itself using computer-based analysis. The computer retrieves the video content, performs automated analysis to extract scene information, objects, events, and other metadata, then associates this extracted metadata with the video content. This automated self-service approach dramatically improves productivity compared to manual metadata creation while keeping the camera device simple.
3Measurement precision
If video content is transmitted to computer for processing, then metadata accuracy is improved, but loss of time in transmission and processing occurs
Solution Approach 1:
The system performs preliminary action by continuously processing video content as it is captured or shortly after capture, rather than waiting until the end of production. The computer retrieves video content and extracts metadata in near real-time, making the metadata available during or immediately after the shooting session. This preliminary processing approach maintains high accuracy while minimizing time loss compared to traditional post-production metadata creation.
Data Source
AI summary
Certain embodiments provide methods and systems that link a video recording device and a processing device to enhance video media content development workflow and enable a variety of features. For example, a video camera may send all or a portion of a recorded video to a separate computer that can determine information to be associated with the recorded video. In some embodiments, the computer extracts information from the recorded video to be embedded or otherwise associated with the recorded video as metadata. In some cases, the computer retrieves information from other sources such as Internet websites for association with the recorded video. In some embodiments, the computer sends the information back to the camera where it is associated with the recorded video stored at the camera. In some embodiments, the computer provides the recorded video and information to other locations and parties, for example, to a director remotely overseeing filming.
