Panoramic Video Streaming Server with Motion-Based Field of View Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Panoramic video streaming requires efficient processing and transmission of large volumes of data, which is challenging due to bandwidth constraints and limited processing power in mobile or resource-constrained devices.
Innovation Solution
A server-based system that processes and streams only the suggested field of view to client devices, using motion prediction and user interaction data to optimize video streaming, reducing the need for full-resolution video transmission and allowing for adaptive buffering and image processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If full-resolution panoramic video is streamed to client devices, then video quality is improved, but bandwidth consumption increases
Solution Approach 1:
The panoramic video stream is divided into multiple segments or regions of interest. Instead of transmitting the entire high-resolution panoramic video, the system segments the video content and transmits only the relevant segments to client devices, reducing bandwidth consumption while maintaining video quality for areas of interest.
Solution Approach 2:
The system applies different quality levels to different regions of the panoramic video. High-resolution video is transmitted for areas of interest where users are likely to focus attention, while lower resolution is used for peripheral areas, optimizing the balance between video quality and bandwidth usage.
2Measurement precision
If panoramic video is processed and transmitted in high resolution, then video quality is improved, but processing power requirements increase
Solution Approach 1:
Video processing and segmentation are performed in advance on the server before transmission to client devices. By preprocessing the panoramic video to identify regions of interest and segment the content beforehand, the system reduces the processing power required at client devices, while still delivering high-quality video where needed.
3Adaptability or versatility
If the entire panoramic video stream is transmitted, then complete coverage is provided, but bandwidth efficiency decreases
Solution Approach 1:
The system extracts and transmits only the essential or relevant portions of the panoramic video stream to client devices. By identifying and extracting regions of interest based on user behavior patterns and event detection, the system provides adequate video coverage while significantly improving bandwidth efficiency by excluding redundant or less important areas.

AI summary
A server includes an input node to receive video streams forming a panoramic video. A module forms a suggested field of view in the panoramic video. The suggested field of view is based upon a viewing parameter, such as a client device motion parameter or a motion prediction parameter. An output node sends the suggested field of view to a client device.
