Rev. 1.0 7
3 Device Driver Structure
This 78Q8430 ST/OS-20 device driver software is a customized version of the generic Teridian Ethernet
device driver software. It is configured with wrapper code for the NexGen TCP/IP protocol stack and
other protocols (RTSP, RTP) to stream the MPEG-2 transport stream. The wrapper code connects the
generic device driver API to the NexGen TCP/IP stack.
3.1 Device Driver Files
