Design of Video Processing Platform with Interchangeable Input-Output Interfaces

摘要

The design and the prototype of a platform for video capturing and real-time processing are presented. Compared to other platforms, support of different input/output interfaces is achieved. Frame double synchronization is implemented by caching data in DDR2 memory leading to video transmission stability. Standard interfaces have been used between the main blocks to simplify the integration of image processing algorithms. The maximum input video resolution and usage of an external decoder for analog video inputs are the main limitations of the platform.
