Meta-data Synthesis Apparatus for Synchronous Video Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for displaying meta-data related to video signals during shooting operations fail to synchronize meta-data with video material, making it inconvenient for cameramen to access and manage meta-data during and after recording.
Innovation Solution
A meta-data display system that extracts and synthesizes meta-data with video signals, allowing for simultaneous display of both image and meta-data on a display apparatus, including scene-information, camera-setting, lens-setting, and dolly-setting data, packed into specific groups for efficient extraction and utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If meta data is recorded separately from video material, then recording flexibility is improved, but meta data cannot be displayed synchronously with video material
Solution Approach 1:
The patent merges meta data and video material into a single integrated recording structure. The meta data is embedded within the video signal stream, allowing both to be recorded together in synchronization. This resolving the contradiction by combining previously separate recording processes into one unified system, enabling simultaneous display and maintaining synchronization.
2Loss of information
If electronic slate apparatus is used to display meta data, then meta data visibility is improved, but device complexity increases
Solution Approach 1:
The patent combines the meta data display function with the existing video monitoring system. Instead of using a separate electronic slate apparatus, the meta data is overlaid on the video signal and displayed on the same monitor used for viewing video content. This integration eliminates the need for additional display devices while maintaining meta data visibility.
Solution Approach 2:
The video monitor is made multi-functional by enabling it to display both video content and meta data simultaneously. The system allows the same display device to serve multiple purposes: viewing the video signal and viewing associated meta data like scene numbers and time codes, thereby eliminating the need for separate dedicated display devices.
3Ease of manufacture
If meta data is inserted at start and end positions only, then recording simplicity is improved, but meta data accessibility deteriorates
Solution Approach 1:
The patent implements continuous meta data insertion throughout the entire video signal stream rather than only at discrete start and end positions. This ensures that meta data is continuously available and synchronized with the corresponding video content throughout the recording, allowing operators to access and view meta data at any point during playback or monitoring.
Data Source
AI summary
The present invention provides a meta-data display system capable of displaying meta data related to a shot video material along with the video material synchronously to the material. The meta-data display system includes an imaging apparatus for generating a video signal representing the video material. The meta-data display system also has a meta-data synthesis apparatus for extracting at least a part of meta data from the video signal including the meta data added for every frame and synthesizing the extracted part with the video signal. The meta-data display system also includes display apparatus each used for displaying a video signal including meta data synthesized therewith. In such a configuration, a part of meta data added to a video signal is extracted and converted into video data, which is then multiplexed in the video signal of every frame. Thus, the display apparatus are each capable of displaying not only an image represented by a video signal, but also meta data related to the image synchronously with the image.
