| 1. An apparatus for rendering a digital content having license information, comprising:
a license processor that acquires a constraint from the license information defining specifics of permission of a rendering
operation of the digital content, the constraint defining conditions between rendering of the digital content designated for
rendering and rendering of a constraint content other than the digital content designated for rendering;
an operation execution command generator that generates an operation execution command for rendering the digital content designated
for rendering and the constraint content according to the constraint acquired by the license processor; and
a content renderer that renders the digital content designated for rendering and the constraint content based on the operation
execution command generated by the operation execution command generator, wherein
the license processor acquires, as a complementary constraint, a spatial constraint indicating a positional relationship on
a rendering screen between the digital content and the constraint content, and
the operation execution command generator generates an operation execution command for arranging the digital content and the
constraint content according to the positional relationship on the rendering screen defined in the spatial constraint acquired
by the license processor.
