[Mp4-tech] DRM MPEG-4

[Huang Zhongyang]

Hi, all,
Moses (http://www.crl.co.uk/projects/moses/) has an implementation of MPEG-4
IPMP-X which was shown in the recent IBC (Sept, 2003).
MPEG-4 IPMPX also has its reference software implementation in IM1, which is
located in MPEG CVS server.
regards,
Huang Zhongyang
