It is not necessary for the end item to be a derived work in order for the GPL to apply. A literal copy is not a derived work; a translation is not a derived work; an executable version of a program is not a derived work of its source code; and so forth. What is necessary is that the "work based on the [GPLed] Program" be more than a mere aggregation of the GPLed component(s) with non-GPLed components. The fact that part of the work-as-a-whole is a descriptor of the GPLed part does not mean all descriptions the GPLed part are governed by the GPL. The critical factor is that the GPLed part will not function properly without the DRM signature.
