  An alternative method to compute the entropy of de Sitter spacetime for
dimensions higher than or equal to five is presented. It is shown that de
Sitter entropy may be obtained from the Bekenstein-Hawking entropy of a
lower-dimensional black hole. This result follows from the existence of a
one-to-one correspondence between de Sitter and a spacetime containing a black
hole localized on a p-brane. Under this correspondence and due to the
holographic principle, the entropy of a five-dimensional de Sitter space may be
obtained from that of a BTZ black hole localized on a 2-brane. For dimensions
higher than five, de Sitter entropy is identified with the entropy of a
Schwarzschild-de Sitter black hole localized on a (d-3)-brane.
