A tuner module for a multi channel is provided to be proper to a small sized device by receiving plural encrypted cable broadcast signals and outputting decrypted signals at the same time. Plural in-band channel tuners(111,112) receive different encrypted cable broadcast signals, and plural analog decrypting units(121,122) demodulates a signal inputted from the channel tuner within a band. An out-of-band channel tuner(130) receives out-of-band data in the frequency bands of a cable broadcast signals, and a digital decrypting unit demodulates a signal inputted from a channel tuner outside the band.
