TUNER DEVICE AND SET TOP BOX

摘要

PROBLEM TO BE SOLVED: To provide a tuner device in which not only an installation area but also costs and power consumption are improved by simultaneously receiving a plurality of channels with one device and preventing a common function from overlapping. SOLUTION: Tuners (12 and 13) of at least one part are simultaneously operated and located to mutually independently select the channels to be received and to supply an intermediate frequency signal corresponding to this channel to outputs (26, 26a and 26b) of the tuners (12 and 13) of at least one part.
