ABSTRACT:
The invention relates to a device for receiving digital signals on the basis of two different standards conveyed on the same medium. A logic-level conversion device receives the digital signals and converts their logic levels into logic levels on the basis of a single standard. Reception is provided for receiving signals coded on the basis of a first standard, which signals are output by the logic-level conversion device. Signals coded on the basis of a second standard are converted into signals coded on the basis of the first standard, which signals are output by the logic-level conversion device. Signals are transferred which are output as converted signals coded on the basis of a second standard into signals coded on the basis of the first standard to the reception device upon reception of signals coded on the basis of the second standard, or for transferring signals output by the logic-level conversion device upon reception of signals coded on the basis of the first standard.
