Abstract

A device is provided for use with an input signal and a selecting signal. The input signal has a first format, and the selecting signal has a first state and a second state. The device comprises a receiving portion and a transcoder portion. The receiving portion can receive the input signal and output a received signal. The transcoder portion is arranged to receive the selecting signal and can output a first transcoded signal when the selecting signal is in the first state and can output a second transcoded signal when the selecting signal is in the second state. The first transcoded signal is based on the received signal and is in a second format. The second transcoded signal is based on the received signal and is in a third format, wherein the first format is different from the second format, the first format is different from the third format and the second format is different from the third format.
