SMPTE 421M

The following documents just became available for download from the SMPTE website:

Trial Publication of SMPTE 421M PROPOSED SMPTE STANDARD for Television:
VC-1 Compressed Video Bitstream Format and Decoding Process

Trial Publication of RP 227 PROPOSED SMPTE RECOMMENDED PRACTICE for Television:
VC-1 Bitstream Transport Encodings

Trial Publication of RP 228 PROPOSED SMPTE RECOMMENDED PRACTICE for Television:

VC-1 is also known as Windows Media Video 9. See this screenshot of VLC playing the Shuttle Discovery Launch video using the VC-1 reference decoder under GNU/Linux. The reference decoder won’t be publicly available until VC-1 becomes a SMPTE standard. Update: the reference decoder is now publicly available at smpte-vc1.org.

    Yes, while the reference decoder is not available now, is there any copy for that?
    Want “VC1_reference_decoder_release6.zip” share.

    The link to the reference VC-1 decoder is not working. Has a new location been created?
    Could you also point to some links which elucidate differences between VC-1 and WMV9 codec-only?

    Thanks!
