Timecode Embedding in Media Streams for Device Sync
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current media production systems face challenges in synchronizing data between multiple devices, particularly in multi-camera setups, leading to time-consuming and costly post-production processes, especially in live events where real-time synchronization is crucial.
Innovation Solution
The system enables synchronization of personal devices like smartphones and tablets with professional media equipment using timecode data and metadata, allowing for seamless integration and embedding of synchronization information into media streams, which can be transmitted wirelessly over RF networks, eliminating the need for manual syncing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual synchronization methods are used during post-production, then synchronization accuracy can be achieved, but time consumption and processing costs increase significantly
Solution Approach 1:
The patent embeds timecode data and metadata into media streams during the acquisition phase rather than performing synchronization during post-production. This preliminary action of embedding synchronization information at the source eliminates the need for time-consuming manual syncing later, directly resolving the contradiction between achieving synchronization accuracy and reducing post-production time
2Manufacturing precision
If professional equipment is used for media capture, then media quality is improved, but device accessibility and cost-effectiveness decrease
Solution Approach 1:
The patent creates a universal synchronization system that works across multiple device types including professional cameras, consumer cameras, and mobile devices. By implementing a common timecode embedding approach that functions across different device categories, the system maintains media quality standards while increasing accessibility and versatility, allowing any device to participate in synchronized multi-camera setups
Solution Approach 2:
The patent introduces timecode data and metadata as intermediary elements that bridge professional and consumer devices. These data structures serve as a universal language that allows devices of varying quality levels to synchronize effectively, enabling consumer devices to integrate into professional workflows without requiring expensive equipment upgrades
3Manufacturing precision
If multiple devices are used for media capture, then media coverage and quality are improved, but data processing complexity increases
Solution Approach 1:
The patent segments synchronization information into distinct data components including timecode data, metadata, and camera acquisition settings. This segmentation allows each component to be independently embedded and processed, reducing the overall complexity of handling synchronized media from multiple devices by breaking down the complex synchronization task into manageable, standardized data elements
Data Source
AI summary
Syncing a personal device to a timecode generator can include acquiring media data with a personal device, receiving, using a timecode module, timecode data over an RF network, transmitting a timecode package including the timecode data to the personal device, decoding the timecode package to obtain the timecode data, and embedding the timecode data into a media stream including the acquired media data.
