Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current broadcasting methods for events with multiple activities require multiple cameras and high-capacity streaming servers to handle panoramic multimedia signals, leading to bandwidth and processing challenges, especially when adapting signals for various client devices and network conditions.
Innovation Solution
A system employing a 4π panoramic camera with a virtual-reality headset that filters and processes multimedia signals to allow clients to select view regions, using a universal streaming server for adaptive content filtering and flow-rate regulation, enabling efficient transmission and display on diverse devices and networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If panoramic multimedia signals are transmitted directly from the source to client devices, then the complete panoramic view is available to clients, but bandwidth requirements and processing needs increase significantly
Solution Approach 1:
The panoramic multimedia signal is segmented into multiple view regions or tiles that can be independently processed and transmitted. Clients receive only the specific segments they need based on their selected view region, rather than the complete panoramic signal, thereby reducing bandwidth consumption while maintaining adaptability.
Solution Approach 2:
The system extracts and transmits only the relevant portions of the panoramic signal that correspond to client-selected view regions. This extraction approach eliminates unnecessary data transmission, reducing bandwidth requirements while preserving client-specific content selection capabilities.
2Area of stationary object
If multiple cameras are used to cover different parts of an event, then complete coverage is achieved, but device complexity and processing requirements increase
Solution Approach 1:
A single panoramic camera is designed to perform the function of multiple cameras by capturing a complete 360-degree or wide-angle view of the event. This universal device provides comprehensive coverage while reducing system complexity compared to using multiple separate cameras and their associated streaming servers.
Solution Approach 2:
The system merges the functionality of multiple cameras into a single panoramic camera that captures the entire event scene in one device. This consolidation reduces the number of cameras and streaming servers needed while maintaining complete coverage of the event area.
3Adaptability or versatility
If panoramic video signals are adapted for different client devices, then compatibility is improved, but processing time and server capacity requirements increase
Solution Approach 1:
The panoramic signal is pre-processed and divided into multiple view regions or tiles before transmission. This preliminary segmentation allows clients to quickly receive and display only their required portion without requiring extensive real-time processing, thereby reducing processing time while maintaining device compatibility.
Solution Approach 2:
Different portions of the panoramic signal are processed with different quality parameters optimized for specific client device characteristics. This local quality adjustment approach improves compatibility across diverse devices while minimizing overall processing requirements by applying intensive processing only where needed.
Data Source
AI summary
A method and a system for selective-content processing of panoramic multimedia signals are disclosed. Features of panoramic cameras and low-latency virtual-reality headsets are exploited to create an advanced efficient system for covering events of diverse and fast-motion actions for the purpose of both broadcasting and data streaming. The disclosed system employs a virtual-reality headset to produce a display of a multimedia signal and generate geometric data defining a view region of the display. A content-filtered signal is extracted from the multimedia signal, according to the geometric data, for broadcasting and dissemination to client devices of a universal streaming server.
