===WVC1===
WVC1, also known as Windows Media Video 9 Advanced Profile, implements a more recent and fully compliant Advanced Profile of the VC-1 codec standard. It offers support for interlaced content and is transport independent. With the previous version of the Windows Media Video 9 Series codec, users could 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{{Citation needed|date=February 2010}}. The Windows Media Video 9 Advanced Profile codec also offers this same improvement in encoding efficiency with interlaced contents{{Citation needed|date=February 2010}}. A decoder for WVC1 is included in [[Windows Media Player|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]].
