The Multimedia Video Engine is an embedded system for real-time image-processing applications. The device captures a video signal from either analog and digital sources, it processes the data by using a high performance digital signal processor (TMS320C6415), and then displays the results on a graphics monitor. Since several video imaging applications require user interaction, a graphical user interface (GUI) has been developed, which is operated by a mouse and a keyboard. Although less complex, the GUI is similar to those we commonly use in standard workstations and can contain a number of objects such as buttons, numerical displays, text, graphs etc. A software environment is also provided to program and customize the platform. Image processing algorithms can be easily integrated into the system as pieces of code written in C language. As for the GUI and the other resources of the board, they can be customized by using provided library functions.

The software engineer has to write pieces of code in response to events the most important of which is the acquisition of a new image in the input buffer. This event starts the main part of the software, where the video processing algorithms are implemented.
