Enhanced trick mode
Applies To: Windows Server 2008, Windows Server 2008 R2
If you intend to stream high volumes of on-demand video content that is indexed to support fast-forward, skip, rewind, and pause capability, you can use the Advanced FF/RW feature in Windows Media Services to improve fast-forward and rewind ("trick mode") functionality for the video portion of encoded files. This feature stabilizes network bandwidth availability by smoothing the rate at which data is sent, and reduces potential server performance bottlenecks by reading less presentation data from the source content disk, all while delivering a seamless experience to clients. Copies of the original source content files must be created that support the different fast-forward or rewind speeds requested by clients. Advanced FF/RW is enabled on the Windows Media server through the WMS Advanced FF/RW Format Media Parser plug-in.
Multicast streaming is not available if Windows Media Services is installed on some Windows Server 2008 and Windows Server 2008 R2 operating systems. For more information, see Decide which version of Windows Server is right for you.
