1. Each contributor grants the DVB Project, under any applicable IPRs (excluding patent, patent applications or trademarks) owned or licensable by such contributor, a nonexclusive, nontransferable, worldwide, royalty-free license to use, copy, distribute to other members of the DVB Project, and make derivative works of any contribution it makes, for the sole purpose of drafting and creating specifications (as defined in Article 8, Paragraph 3), draft specifications, reports or other documents made pursuant to the activities of the DVB (“Materials”).
   
   
2. Upon approval of such Materials by the DVB Project, each contributor further grants the DVB Project, under any applicable IPRs (excluding patent, patent applications or trademarks), owned or licensable by such contributor, a nonexclusive, nontransferable, worldwide, royalty-free, perpetual, irrevocable, sublicenseable license to (a) use, copy, distribute and make derivative works of any contribution included in such approved Materials, and to implement such approved Materials and derivative works for purposes of implementing a specification, and (b) use, make, reproduce, sell, distribute, import or transmit implementations of such approved Materials and derivative works for purposes of implementation of a specification.  Subject to the rights granted herein, all right, title and interest in and to an individual contribution shall remain with the contributor.
   
   
3. Ownership of the copyright in Materials created by the DVB Project or any of its Modules, Committees or other bodies shall vest in the DVB Project.  Members of the DVB Project shall be allowed to make copies of and use such Materials for their own use free of charge.
   
   
4. The Steering Board may grant licenses to third parties to specifications on terms and conditions determined by the Steering Board, consistent with the policies of the DVB Project.
   
   
5. A specification referenced in a DVB specification is normative if it refers to a document that sets out provisions that are necessary to implement a mandatory or optional provision of the specification. The text of a normatively referenced document must be publicly available for evaluation without contractual restrictions other than those reasonably intended to restrict duplication and redistribution (which may include the obligation to pay reasonable fees).  A copyright license to implement the referenced document must be available to DVB implementers on fair, reasonable, and non-discriminatory terms and conditions.  The Steering Board may make an exception to the above provisions if it determines that an exception is in the interest of the DVB Project.
