Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video transmission systems face challenges in transmitting uncompressed high-resolution video signals over standard networks with low latency, as conventional interfaces have limited range and existing networks struggle with high-resolution video compression at 4K, 4:4:4, and 60 fps.
Innovation Solution
An integrated switching arrangement with video and network interfaces, a frame buffer controller, and a connection matrix that supports uncompressed video transmission, incorporating video processing units for scaling, clipping, and compression, and a configurable addressing scheme for routing data streams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If uncompressed high-resolution video signals are transmitted over standard networks, then transmission quality is improved, but network latency increases and transmission becomes difficult
Solution Approach 1:
The patent merges multiple previously separate devices (video interface, network interface, frame buffer controller, connection matrix, and video processing units) into a single integrated switching arrangement. This integration eliminates inter-device communication overhead and reduces latency while maintaining uncompressed high-resolution video transmission quality.
Solution Approach 2:
The integrated switching arrangement is divided into distinct functional modules (video interfaces for receiving/sending video data, network interfaces for network connection, frame buffer controller for memory management, connection matrix for routing, and video processing units for scaling/compression). This segmentation allows each module to be optimized for its specific function while working together efficiently within the same device.
2Length of stationary object
If video signals are transmitted over greater distances, then coverage range is improved, but standard video interfaces become insufficient due to limited range
Solution Approach 1:
The integrated switching arrangement acts as an intermediary device that receives video signals from sources via video interfaces, processes and buffers them, then transmits them over network interfaces to distant sinks. This mediator approach enables long-distance transmission while maintaining signal quality and compatibility.
Solution Approach 2:
The device provides universal functionality by combining multiple interfaces and processing capabilities in one unit, allowing it to adapt to different video sources, sinks, and network configurations while enabling transmission beyond the limited range of standard video interfaces.
3Adaptability or versatility
If multiple devices (sources, sinks, routers, processing units) are used for video transmission, then functional capabilities are improved, but system complexity increases
Solution Approach 1:
The patent combines multiple previously separate devices into a single integrated switching arrangement that includes video interfaces, network interfaces, frame buffer controller, connection matrix, and video processing units. This consolidation maintains all necessary functional capabilities while reducing system complexity by eliminating the need for multiple separate devices working together.
