The connection between braided Hopf algebra structure and quantum group covariance of the deformed oscillators is constructed explicitly. In this context we provide deformations of the Hopf algebra of functions on SU(1,1). Quantum subgroups and their representations are also discussed. (C) 2002 American Institute of Physics.
