``Seeing that APS went to the extent of spelling them out...do they own them?....do they have exclusivity to a unique bit stream...or any of the other items?``

``NO they do not....``

They do not have exclusivity in a technical sense....however... in spelling them out to be included in an IFE device....can they fend off the Panasonic`s of the IFE arena....when it comes to self contained portables?

They spelled the layers to be utilized first in an IFE device...
