WVC1 is also known as Windows Media Video 9 Advanced profile, it implements a more recent and fully compliant advanced profile of the Vc1 codec standard. It supports interlaced content and is transport independent. With the previous version of the Windows Media Video 9 series codec users can deliver progressive content at data rates as low as one third that of the MPEG 2 codec and still get equivalent or comparable quality to MPEG 2, the windows 9 advanced profile codec also offers this same improvement in encoding efficiency with interlaced contents, a decoder for Wvc1 is included in Windows Media Player 11, which is bundled with Windows Vista and is available as a download for Windows XP, this implementation is supported in Microsoft Silverlight.
