Multi-View Live Event Streaming With Synchronized Viewpoint Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies limit the shared experience of a live event to a single, preordained perspective, lacking immersive interaction and synchronization among remotely located individuals and local attendees, preventing a unified, interactive experience.
Innovation Solution
A platform that enables multiple live streams from various viewpoints, including augmented reality content, allowing participants to dynamically switch between perspectives and interact virtually, synchronized through clock synchronization algorithms to ensure seamless transitions and synchronized delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single preordained perspective is used for live event broadcasting, then the broadcasting system is simple and easy to operate, but the immersive experience and interaction among participants are limited
Solution Approach 1:
The patent divides the live event coverage into multiple independent viewpoint streams captured by different source devices. Each device captures a distinct perspective, and these segmented streams are distributed to client devices, allowing participants to select and switch between viewpoints dynamically, thereby creating an immersive experience without requiring a completely new monolithic system
Solution Approach 2:
The platform is designed to handle multiple viewpoint streams simultaneously and serve diverse client devices with different capabilities. The system can adaptively distribute appropriate streams to different clients based on their selections and device characteristics, making the system versatile while managing complexity through standardized protocols and adaptive streaming
2Adaptability or versatility
If multiple live streams from various viewpoints are provided, then the immersive experience is enhanced, but the synchronization and coordination among streams become complex
Solution Approach 1:
The system implements feedback mechanisms where client devices report their selected viewpoints and device capabilities to the platform. The platform uses this feedback to adaptively distribute the appropriate viewpoint streams and adjust distribution strategies to maintain synchronization and ensure reliable delivery across multiple concurrent streams
3Adaptability or versatility
If live streams are distributed to multiple client devices, then the shared experience among participants is enhanced, but the network bandwidth and server load increase
Solution Approach 1:
The system distributes different viewpoint streams to different client devices based on local user preferences and device characteristics. Each client receives only the specific streams it needs rather than all possible streams, optimizing network bandwidth utilization while maintaining the shared experience through selective distribution
Solution Approach 2:
The platform implements adaptive streaming where the full resolution and quality streams are distributed only when necessary, while providing lower bandwidth alternatives when appropriate. This partial action approach reduces overall network load while still delivering adequate viewing experiences across multiple devices
Data Source
AI summary
A system interconnects multiple client devices over a network. A local group of the client devices is located at a live event and a remote group is located remote from the live event. Each client device of the local group is a potential source of a live stream which, when rendered by another client device, causes display of a vantage point of the live event. The system dynamically updates a subscription list to include an indication of any client device of the local group that is actively live streaming and remove an indication of any client device of the local group that terminated live streaming. The system can enable selective access to any live streams of any client device of the updated subscription list and disable access to any live streams of any client device removed from the updated subscription list.
