Kernel streaming

From Wikipedia, the free encyclopedia

In Microsoft Windows terminology, Kernel Streaming is a technique that supports kernel-mode processing of streamed data. It enables efficient real-time streaming for multimedia devices such as sound cards and TV tuner cards. Kernel streaming allows a device driver to create DirectShow-like filters and pins in kernel mode, providing access to hardware, lower latency communication and still be used within a DirectShow filter graph.

Music players such as foobar2000 and Winamp sometimes support kernel streaming through plugins. Compared to the regular "wave out method" in Microsoft Windows, kernel streaming requires less CPU time. This comes at the expense of bypassing the KMixer and Windows volume control. One popular use of kernel streaming is "online broadcasting," via which one can broadcast a song through the internet to others.
