What is the IEEE 1394 architecture for A/V devices Windows 98 support?
In Windows 98, the Microsoft IEEE 1394 driver stack supports host adapaters compliant with the Open Host Controller Interface (OHCI or OpenHCI) standard. Windows 98 also supports the Adaptec and PCILynx adapter. Windows 2000 supports only OHCI-compliant adapters. Microsoft is providing base-level support for IEEE 1394 A/V devices in Windows 98 and in Window 2000 through the WDM Stream class, which supports components such as DVD decoders, MPEG decoders, video decoders, tuners, and audio codecs. The WDM Stream class supports a uniform model for standard and custom data types, following the kernel streaming conventions described in the current version of the Windows 2000 DDK to support data transfer between kernel drivers without requiring a transition to user mode. Digital video (DV) capture and editing applications communicate with the device driver layer through the A/V framework and the DirectShow DV and MPEG-2 codecs. How about Windows 2000 support for storage, printers, and scanner
