On-the-fly Scaler for High Definition Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high definition capture devices that do not operate in real time become less useful as multimedia data becomes high definition, due to duplication and increased size caused by separate high definition and standard definition capture engines.
Innovation Solution
A high definition capture engine with an on-the-fly scaler for horizontal and vertical scaling, capable of transporting high or standard definition digital video streams to main memory, supporting various input and output formats, and allowing Region of Interest definition for efficient data capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate high definition and standard definition capture engines are used, then high definition capture capability is achieved, but device size and complexity increase
Solution Approach 1:
The capture engine is designed to perform both high definition and standard definition capture operations using the same hardware infrastructure. The scaler can dynamically adjust resolution to handle different output requirements, allowing a single engine to replace what would traditionally require separate dedicated engines for each resolution level.
Solution Approach 2:
The system changes operational parameters (resolution, scaling factors) rather than requiring different hardware configurations. By modifying the scaling parameters in real-time, the same capture engine can adapt between high definition and standard definition modes without physical reconfiguration or additional dedicated hardware.
2Productivity
If real-time high definition data capture is implemented, then capture speed is improved, but processing complexity increases
Solution Approach 1:
The scaler performs preliminary scaling operations on the captured high definition data before it proceeds to storage or further processing. By pre-scaling the data in real-time during capture, the system reduces the burden on subsequent processing stages and enables efficient handling of high definition streams without requiring complex post-capture processing.
