Synchronized Multi-Stream Video Transmission for Low-Bandwidth Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video and audio transmission systems for remote inspection incur significant overhead and reduce transmission efficiency and quality due to multiplexing multiple data streams into time-stamped packets, which is not viable for bandwidth-limited communications networks like satellite links.
Innovation Solution
A system that encodes multiple video and audio streams into a single synchronized frame, reducing overhead by eliminating the need for timestamping and allowing transmission in a single cycle, with separate packetization for video, audio, and telemetry data, optimizing bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple data streams are multiplexed into time-stamped packets for transmission, then remote inspection functionality is enabled, but transmission overhead increases and efficiency decreases
Solution Approach 1:
The patent extracts and eliminates the timestamping mechanism from the packetization process. By removing timestamps and using synchronized frame numbering instead, the system reduces packet overhead while maintaining the ability to reconstruct and display multiple video streams in correct temporal sequence at the remote location.
Solution Approach 2:
The patent segments the transmission process into distinct phases: synchronized frame capture at the source, efficient packetization without timestamps during transmission, and post-processing with frame counting and synchronization at the destination. This segmentation allows each phase to be optimized independently, reducing overall overhead.
2Reliability
If multiple data streams are multiplexed into packets with timestamps, then remote monitoring is achieved, but transmission quality and efficiency are reduced
Solution Approach 1:
The patent removes the timestamping component from the packet structure entirely. Instead of embedding timestamps in each packet, the system uses frame counters and synchronization markers that require significantly less bandwidth, thereby improving transmission efficiency while maintaining monitoring capability.
Solution Approach 2:
The system performs preliminary synchronization at the frame capture stage, where all video streams are synchronized to a common time reference before packetization. This preliminary action eliminates the need for continuous timestamping during transmission, as synchronization is established upfront and maintained through frame numbering.
3Stability of the object's composition
If timestamping is used for synchronizing multiple video streams, then frame synchronization is achieved, but packet overhead increases
Solution Approach 1:
The patent extracts the synchronization function from timestamping and implements it through frame counters and synchronization markers. Each packet contains a frame counter that increments with each frame, and periodic synchronization markers that reset counters, providing robust synchronization without the overhead of full timestamps.
Solution Approach 2:
Instead of embedding time information in each packet (timestamps), the patent inverts the approach by using sequence numbers and synchronization markers. The receiver reconstructs temporal information by counting frames and using sync markers, which is more efficient than transmitting actual timestamp values in every packet.

AI summary
Systems, methods, and storage media for transmitting multiple data streams over a communications network for remote inspection are disclosed. Exemplary implementations may: preprocess a plurality of video streams into a single synchronized frame; encode the single synchronized frame; packetize the encoded single synchronized frame as a multiplexed packet for transmission with multiple multiplexed packets over the communications network; depacketize the multiplexed packet received over the communications network to produce the single synchronized frame; and decode the synchronized frame into the plurality of video streams for remote inspection.
