We give a complete classication of intertwining operators (symmetry breaking operators) between spherical principal series representations of *G* = *O*(*n*+1, 1) and *G*' = *O*(*n*, 1). We construct three meromorphic families of the symmetry breaking operators, and find their
distribution kernels and their residues at all poles explicitly. Symmetry breaking operators at exceptional discrete parameters are thoroughly studied.
We obtain closed formulae for the functional equations which the
composition of the the symmetry breaking operators with the Knapp-Stein intertwining operators of *G* and *G*' satisfy, and use them to
determine the symmetry breaking operators between irreducible composition factors of the spherical principal series representations of *G*
and *G*'. Some applications are included.
