Video Communication System Using Simultaneous Frame Block Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video communication systems over internet/intranet introduce significant delay, typically exceeding half of the inter-frame time interval, which is not suitable for applications requiring low latency and high visual quality, such as medical endoscopy and high-speed feedback control loops.
Innovation Solution
A video data communication system that combines image acquisition, compression, and transmission by simultaneously handling different parts of an image frame or field, using image blocks and headers, allowing for low latency and low bandwidth communication over internet/intranet protocols like IP, with optional encryption and decryption.

Engineering Contradiction Analysis
1Quantity of substance
If video data is transmitted over internet/intranet using compression and communication protocols, then bandwidth consumption is reduced and universal interconnection is enabled, but transmission delay increases significantly (exceeding half of inter-frame time interval)
Solution Approach 1:
The patent divides a complete video frame into multiple image blocks that can be processed and transmitted independently. This segmentation allows different parts of the same frame to be handled simultaneously by multiple processing units, reducing overall transmission delay while maintaining compression efficiency for bandwidth reduction
Solution Approach 2:
The patent performs preliminary compression and packaging of image blocks before transmission, organizing data into a structure that enables efficient network delivery. This preliminary processing reduces the time required during actual transmission while achieving significant bandwidth reduction
2Loss of time
If traditional video cabling is used for direct video link, then transmission delay is low, but bandwidth consumption is high and cable length is limited
Solution Approach 1:
By segmenting video frames into image blocks that can be transmitted independently over network protocols, the system achieves low-latency transmission comparable to direct cabling while reducing bandwidth requirements through compression
Solution Approach 2:
The patent introduces an intermediary processing system that converts direct video signals into compressed network packets and reconstructs them at the receiving end, enabling low-latency transmission over standard network infrastructure without requiring specialized video cabling
3Quantity of substance
If compression is applied to reduce bandwidth, then data amount is reduced, but processing time and complexity increase
Solution Approach 1:
The patent divides compression processing into independent image block operations that can be executed simultaneously by multiple processing units. This parallel processing approach reduces overall processing time and distributes computational complexity across multiple units, making the system more manageable and efficient
