Abstract A diagonalization of the absolute continuous component of a selfadjoint block Toeplitz operatorT with rational matrix symbol is given. The diagonalizing operator is stated in terms of a realization of the symbol. Furthermore, an explicit description is derived for the total multiplicity of the spectrum ofT and of the multiplicity at each spectral point ofT.
