Solution Overview
Problem
Existing video production systems for video conferencing suffer from high latencies due to the incorporation of multiple video feeds, making communication between participants difficult.
Innovation Solution
Implementing a dynamically adjustable time clock delay at a video access point device to synchronize and combine input video streams, based on calculated latency measures, to generate a low latency output stream suitable for video conferencing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple video feeds are incorporated into the output stream, then the video production system can support multiple video sources, but the latency increases making communication difficult
Solution Approach 1:
The system dynamically adjusts the time clock delay parameter based on current network conditions and latency measurements. The latency compensation value is not fixed but adapts in real-time to optimize the balance between supporting multiple video feeds and maintaining acceptable latency for video conferencing
Solution Approach 2:
The patent changes the time clock delay parameter dynamically based on measured latency values. By adjusting this parameter, the system can compensate for the additional latency introduced by processing multiple video feeds, thereby maintaining acceptable performance for video conferencing applications
2Ease of operation
If a fixed time clock delay is used to synchronize video streams, then synchronization is simplified, but latency cannot be optimized for video conferencing
Solution Approach 1:
The system transitions from a static time clock delay to a dynamic one that adjusts based on measured latency. The video production system continuously monitors latency and modifies the time clock delay accordingly, maintaining synchronization while optimizing for low-latency video conferencing requirements
Solution Approach 2:
The system implements a feedback mechanism where latency is measured from the video streams and this measurement is used to adjust the time clock delay. This closed-loop control allows the system to automatically optimize synchronization parameters based on actual performance, achieving both ease of operation and low latency

AI summary
Systems, devices and processes and described herein to improve the generation of video content in video production systems. In general, the systems, devices and processes facilitate the incorporation of one or more remotely captured video streams into an output video stream for use in video conferencing. Specifically, the systems, devices and processes provide for the use of a dynamically adjustable time clock delay to generate a relatively low latency output video stream suitable for use in video conferencing. The use of dynamically adjustable time clock delay allows one or more input video streams to be generated by one or more remote video-capture devices, transmitted to a video access point device, and selectively combined at the video access point device into the output video stream with relatively low latency suitable for video conferencing.
