A mobile broadcast receiving apparatus capable of stably receiving mobile
broadcasting even with rapid variation in a reception level and yet
capable of reducing the power consumption and a control method for such
apparatus are provided. The mobile broadcast receiving apparatus, which
selectively receives a broadcast radio wave from a geostationary
satellite or a radio wave retransmitted from a gap filler, controls
switching of at least one of a dynamic range of a low noise amplifier
(LNA), a time constant of an automatic gain control circuit (AGC), and
ON/OFF of an antenna diversity, according to a reception status of the
mobile broadcast receiving apparatus.
