Dual-Stream Display Control for Concurrent Multi-Quality Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surveillance systems face difficulties in concurrently displaying video data of low and high image quality due to differences in bit rates, and existing systems struggle to allow simultaneous display of both qualities, leading to insufficient information retrieval from low-quality display apparatuses.
Innovation Solution
A display control system that enables concurrent reception and display of video data of different qualities by transmitting sub-streaming alongside main streaming, allowing for the simultaneous display of low and high-quality video data through a reception apparatus and method that coordinates the transmission and reception of these streams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a surveillance system selectively displays video data of low image quality or high image quality, then network bandwidth consumption is reduced, but users cannot concurrently check both qualities
Solution Approach 1:
The video stream is segmented into two separate streams: main streaming (high quality) and sub streaming (low quality). This segmentation allows the system to transmit both quality levels simultaneously over the network, enabling users to concurrently access and display both video qualities on different display apparatuses without excessive bandwidth consumption on any single path.
2Manufacturing precision
If different display apparatuses are used for low and high image quality, then video quality requirements are met, but the low-quality display apparatus does not display video data when high-quality display is active
Solution Approach 1:
The display control apparatus is designed with multi-functionality to handle both main streaming and sub streaming simultaneously. It can selectively output high-quality video to high-quality display apparatuses and low-quality video to low-quality display apparatuses based on their capabilities, ensuring that each display apparatus receives appropriate quality video data and users can access information from both streams independently.
3Loss of energy
If only main streaming is transmitted, then network bandwidth consumption is minimized, but concurrent display of different qualities is not enabled
Solution Approach 1:
The system applies local quality by transmitting high-quality main streaming to display apparatuses capable of displaying high-quality video, while simultaneously transmitting low-quality sub streaming to display apparatuses with lower display capabilities. This ensures that each display apparatus receives video data of appropriate quality, minimizing overall network bandwidth consumption while maximizing video information availability across different display devices.

AI summary
A reception apparatus and reception method receive sub streaming concurrently with receiving main streaming. A streaming apparatus transmits sub streaming concurrently with transmitting main streaming. An operating room system includes cameras that acquire image data and an audiovisual controller that receives sub streaming from the cameras concurrently with receiving main streaming from one of the cameras. A vehicle control system includes cameras mounted onto a vehicle and an integrated unit that receives sub streaming from the cameras concurrently with receiving main streaming from one of the cameras.
