MPEG LA welcomes any party that believes it has patents which are
essential to the ATSC Standard to submit them for an evaluation of
their essentiality by MPEG LA's patent experts and inclusion in the
License if determined to be essential. Interested parties may request
a copy of the terms and procedures governing patent submissions at
http://www.mpegla.com/atsc/atsc-licensors.cfm. MPEG LA's objective is
to provide worldwide access to as much ATSC essential intellectual
property as possible for the benefit of licensees (new patent holders
and essential patents may be added at no additional royalty during the
current term of the License).

MPEG LA, LLC

MPEG LA is the world leader in alternative technology licenses,
enabling users to acquire worldwide patent rights necessary for a
technology standard or platform from multiple patent owners in a
single transaction as an alternative to negotiating individual
licenses. Wherever an independently administered one-stop patent
license would provide a convenient marketplace alternative to assist
users with implementation of their technology choices, the licensing
model pioneered and employed by MPEG LA may provide a solution. By
balancing patent users' interest in reasonable access with patent
owners' interest in reasonable return, MPEG LA creates the opportunity
for adoption of new technologies and fuels innovation. MPEG LA's
initial licensing program for MPEG-2 digital video compression helped
produce the most widely employed standard in consumer electronics
history, and the MPEG LA(R) Licensing Model has become the template
for addressing other technologies. Today MPEG LA manages licensing
programs consisting of essential patents in 57 countries. MPEG LA is
an independent licensing administrator; it is not related to any
standards agency and is not an affiliate of any patent holder. For
