A set-top-box (STB) for receiving cable TV (CATV) transmission and connecting to the Internet. The STB comprises a first tuner arranged to receive a signal transmitted on a channel via a physical medium e.g. a cable network; and at least a first decoder (e.g. a MPEG decoder and a MAC decoder) arranged to convert a signal supplied to the decoder into a first output signal. The STB is characterized by a second tuner providing a signal to a second decoder (e.g. a MPEG decoder) arranged to convert a signal received from the second tuner to a second output signal that can co-exist with the first output signal. Thereby either two digital TV channels can be received simultaneously or a TV channel can be received while IP data from the Internet is received.
