A modular hip implant is disclosed that includes a base member that is to be attached to a pelvic bone, and a cup for accommodating a hip joint prosthesis. The dielectric is then exposed to light through a mask, is seeded with a metal and is subjected to a temperature treatment. When a power source potential VDD is supplied to one end of the wires to be tested and a ground potential VSS is supplied to the other end of the wires to be tested, a current path can be formed including the wires to be tested. Furthermore, the disparity of the subtitle can be adjusted by taking into account the disparities of one or more objects in an underlying image to be displayed with the subtitle. A control channel decoder can use a circular Viterbi decoding algorithm and a circular trellis check.
