  A generalization of continuous biframe in a Hilbert space is introduced and a
few examples are discussed. Some characterizations and algebraic properties of
this biframe are given. Here we also construct various types of continuous
K-biframes with the help of a bounded linear operator. Relationship between
continuous K-biframe and quotient operator is established. Finally, we define
continuous K-biframe for the tensor products of Hilbert spaces and give an
example.
