Digital media elements
The Digital Media Elements (DME) architecture is designed with a systematic approach to handle concurrent real-time image processing, audio and video compression and/or decompression, audio and video synchronization, network transmission and graphic user interface. The software is designed with a hierarchical approach to ensure complex applications can be developed, integrated and tested systematically. DME technology allows us to quickly and efficiently provide highly integrated solutions for our customers.

From a functionality point of view, DME is organized into four libraries.

• Media Application Library (MapLib)
• Media Signal Processing Library (MspLib)
• Network Library (NetLib)
• Graphic User Interface Library (GuiLib)
