Video Stream Time Code Synchronization for Digital Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for providing digital content lack efficiency in real-time distribution and management, particularly in synchronizing advertisements and text commentary with live video streams, often requiring resource-intensive on-site operations and risking timing discrepancies.
Innovation Solution
A method and system that involve embedding time code markers in video streams, allowing for remote association and synchronization of content, including advertisements and commentary, by using a video encoder, servers, and controllers to impose delays and manage content distribution, enabling remote management and synchronization of digital content presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If on-site operations are used to synchronize advertisements and text commentary with live video streams, then synchronization accuracy can be maintained, but resource expenditure increases significantly
Solution Approach 1:
The patent creates multiple copies of the live video stream, with each copy processed independently by different controllers. This allows remote synchronization operations on copies while the original stream continues, reducing the need for resource-intensive on-site operations and enabling efficient content association without compromising synchronization accuracy.
Solution Approach 2:
The patent introduces time code markers as intermediary elements that are embedded in the video stream and used to synchronize content association remotely. These time code markers act as mediators between the video stream and the content management system, enabling accurate synchronization without requiring physical presence at the content source.
2Speed
If real-time distribution of digital content is implemented, then delivery speed improves, but timing synchronization between content elements becomes more difficult
Solution Approach 1:
The patent embeds time code markers in advance within the video stream during encoding. This preliminary action ensures that timing information is already embedded in the stream, allowing for accurate synchronization during real-time distribution without requiring complex post-processing or coordination delays.
3Adaptability or versatility
If multiple copies of video streams are distributed for content association, then content management flexibility improves, but system complexity increases
Solution Approach 1:
The patent divides the video distribution system into separate functional segments: the video encoder that embeds time code markers, multiple distribution servers that create and manage copies, and controllers that associate content with specific copies. This segmentation allows each component to perform its function independently, improving content management flexibility while keeping individual components relatively simple.

AI summary
A system and method for disseminating digital content, including receiving a video stream having embedded time code markers, copying the video stream, distributing a first copy to a player with a desired delay, distributing a second copy for association of content, and associating content with the second copy during the delay for playing of the first copy and the associated content at the player.
