Aggregated Video Frame Transmission for AR Headsets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional motion tracking systems in augmented and virtual reality headsets face challenges with camera coverage gaps and inefficient data transmission from multiple cameras over limited-bandwidth channels.
Innovation Solution
The method involves combining frames from multiple video streams into a single image, including metadata, and transmitting this image via a single transmission channel, which can be a limited-bandwidth channel like a USB cable, to efficiently transmit video data from multiple cameras attached to a wearable headset.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple cameras are added to eliminate coverage gaps, then camera coverage is improved, but data transmission efficiency deteriorates due to limited bandwidth
Solution Approach 1:
The patent combines multiple video frames from different cameras into a single composite image for transmission. Instead of sending separate video streams from each camera over the limited-bandwidth channel, the system merges them into one aggregated image data structure, reducing the total data transmission load while maintaining coverage from all camera viewpoints.
Solution Approach 2:
The patent embeds multiple camera frames within a single composite image structure. Each camera's frame is nested as a component within the larger aggregated image, allowing efficient packaging and transmission of multiple video sources through a single data container over the bandwidth-constrained channel.
2Loss of information
If multiple video streams are transmitted separately, then data completeness is improved, but transmission bandwidth requirement increases
Solution Approach 1:
The system merges multiple video streams into a single aggregated image transmission. By combining the data from multiple cameras into one composite structure, the patent reduces the number of separate transmission channels needed while preserving all video information through systematic organization of frames within the aggregated image.
3Productivity
If frames from multiple cameras are combined into a single image, then transmission efficiency is improved, but processing complexity increases
Solution Approach 1:
The patent segments the composite image into distinct frame regions, each corresponding to a specific camera. By organizing the aggregated image with clearly defined segments for each camera's frame, the system simplifies the processing required to create and decode the composite image, making it easier to manage the complexity of handling multiple video streams.
Solution Approach 2:
The patent introduces an intermediary data structure that facilitates the combination of multiple frames. This intermediate representation serves as a bridge between the raw video streams and the final transmitted image, simplifying the processing by providing a standardized format for integrating frames from different cameras before transmission.
