Windows Media Video (WMV) is a compressed video compression format for several proprietary codecs developed by Microsoft. The original video format, known as WMV, was originally designed for Internet streaming applications. The other formats, such as WMV Screen and WMV Image, cater for specialized content. Through standardization from the Society of Motion Picture and Television Engineers (SMPTE), WMV 9 has gained adoption for physical-delivery formats such as HD DVD and Blu-ray Disc.
The WMV file type is primarily associated with 'Windows Media File' by Microsoft Corporation.It requires version 8+ of the Windows Media Player. Now you can easily watch WMV video on several media players, such as 5KPlayer, VLC, The KMPlayer, Mplayer, and with Microsoft Flip4Mac software, you are able to play WMV files on your QuickTime Player.

Microsoft claims that WMV 9 provides a ompression ratio that is 2x better than MPEG-4, and 3x better than MPEG-2; Microsoft also claims that WMV 9 is 15-50% better than WMV 8 in terms of compression efficiency. But, one test reportshowed that WMV 9 had worse compression efficiency than WMV 8, andmany 3rd party WMV compilers have had worse performance than Windows Movie Maker.
Windows Media DRM:
Windows Media DRM a Digital Rights Management service for the Windows Media platform. It is designed to provide delivery of audio and/or video content over an IP network to a PC or other playback device in such a way that the distributor can control how that content is used.While none of the WMV codecs themselves contain any digital rights management facilities, the ASF container format, in which a WMV stream may be encapsulated.
Windows Media DRM, which can be used in conjunction with WMV, supports time-limited subscription video services such as those offered by some video/audio company. As a component of Windows Media Connect, it is supported on many modern portable video devices and streaming media clients such as the Xbox 360.
