After standardization by the Society of Motion Picture and Television Engineers SMPTE,12 WMV version 9 was adopted for physical delivery formats such as HD DVD and Blu ray Disc and became known as VC 1. Microsoft also developed a digital container format called Advanced Systems Format to store video encoded by Windows Media Video. HistoryeditIn 2. Microsoft drafted a video compression specification based on its WMV 9 format and submitted it to SMPTE for standardization. The standard was officially approved in March 2. SMPTE 4. 21. M, better known as VC 1, thus making the WMV 9 format an open standard. VC 1 became one of the three video formats for the Blu ray video disc, along with H.

MPEG 4 AVC. 34Container formateditA WMV file uses the Advanced Systems Format ASF container format to encapsulate the encoded multimedia content. While the ASF can encapsulate multimedia in other encodings than those the WMV file standard specifies, those ASF files should use the. ASFfile extension and not the. Windows Mpeg4 Codec' title='Windows Mpeg4 Codec' />WMV file extension. The ASF container can optionally support digital rights management using a combination of elliptic curve cryptography key exchange, DES block cipher, a custom block cipher, RC4 stream cipher and the SHA 1 hashing function. Although WMV is generally packed into the ASF container format, it can also be put into the Matroska6 or AVI container format. The resulting files have the. MKV and. AVI file extensions, respectively. One common way to store WMV in an AVI file is to use the WMV 9 Video Compression Manager VCM codec implementation.

The codec achieves a higher compression ratio and image quality than WMV 9 for still images as files encoded with WMV Image store static images rather than full motion video. Since the format relies on the decoder player to generate video frames in real time, playing WMV Image files even at moderate resolutions e. The latest version of the format, WMV 9.
