Abstract

A receiver for receiving different types of signals includes a receiver input for receiving a receiver input signal. A signal converter can convert the receiver input signal into a receiver output signal. A receiver output is connected to a converter output of the signal converter, for outputting the receiver output signal The receiver has a control input via which controllable parameters of the receiver can be controlled. The receiver further includes a memory. The memory has a first memory part in which a first set of receiver control parameters values for the receiver are stored and a second memory part in which a second set of receiver control parameters values for the receiver are stored. The receiver being able to receive a selected type of signals when the receiver is set in accordance to a selected set. A connection is present which connects a selected memory part to the a control input, for setting receiver parameters of said receiver to receiver control parameters values stored in said selected memory part. A switch between the control input and the memory parts, can switch the connection from a selected memory part to another memory part. A controller is connected to the switch, for selecting a set and controlling the switch to switch the connection to a memory part corresponding to the selected set.

Claims
