Licensing information, comments, notes, or URL for further information

The British Broadcasting Corporation ("BBC") has one patent family identified here that includes one or more claims that the BBC believes may be essential for implementing technology set forth in "" ("Specification"), depending on the implementation selected by the implementer ("Essential Claims").

Should the Specification be adopted as a RFC, in the event that the Essential Claims are necessarily infringed by the implementation of the adopted Specification, the BBC agrees to grant to any party making such implementation ("Licensee") a licence ("Licence") to such Essential Claims under fair, reasonable and non-discriminatory terms and conditions, on condition that the Licensee grants to the BBC and its subsidiaries a reciprocal licence to any patented claims in the Licensee's ownership or control which may be essential for implementation of the Specification in products and services offered by the BBC and its subsidiaries. The Licence may be terminated with immediate effect by the BBC if the Licensee initiates a claim of patent infringement, directly or indirectly, against the BBC or its subsidiaries in relation to the Specification.

Note: The individual submitting this template represents and warrants that he or she is authorized by the Patent Holder to agree to the above-selected licensing declaration.

VIII. Other Notes

Additional notes

For some reason, the form rejected the correct patent title "Content delivery" (too short maybe?), so I added the name of the patent category in parentheses to make it longer.

Only those sections of the relevant entry form where the submitter provided information are displayed above.
