[Mp4-tech] DRM MPEG-4

[Panos Kudumakis]

Many thanks to Boris and Huang for their replies
MPEG IPMP eXtensions specification represents the best balance achieved to date
between the IPR protection needs expressed by content owners and the demand for
interoperability coming from end users and manufactures Therefore a number of
companies have commit to support it  See their press release at:
http://www.crl.co.uk/projects/moses/Public/docs/IPMPX PressRelease.pdf
Also efforts are in place to signal ISMAcrypt as an IPMPX Tool

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
