Chapter 24. DirectX and Windows 98 Video > Viewing Web-Based Video with NetShow

Viewing Web-Based Video with NetShow

Microsoft puts the ASF video format through its paces with the NetShow Player that comes with Windows 98. NetShow is essentially an ActiveX control that supports media streaming. This means that NetShow uses special codecs that enable it to decode incoming media streams on-the-fly. The result is that you can view content-rich media with only a few seconds delay. This is a far cry from having to load a large video file that, if you're accessing it from the Web, could take minutes or even hours to download. And there are no storage worries with NetShow because the player doesn't save the incoming stream in permanent storage. It buffers the incoming data, plays it, and then tosses it in the bit bucket.


NetShow is also capable of both unicast and multicast content delivery. Unicast delivery means that a separate copy of the ASF file is sent to each client that asks for it. The advantage to this approach is that after the entire stream is received, the user can then replay the media and, in some cases, rewind and fast forward to specific sections. The disadvantage to this approach is that each stream usurps a large chunk of network bandwidth.
