Abstract
A functional module card and a host apparatus according to the present invention can constitute the digital broadcasting receiver apparatus. The functional module card includes a card controller and a tuner section. The tuner section inputs a digital broadcasting signal, generates a transport stream (referred to as a TS hereinafter) and a TS clock for transferring the TS, and directly transfers the TS and the TS clock to a decoder and descrambler of the host apparatus via a bus according to the TS clock. A data transfer method for transferring data between the card controller and the host controller of the host apparatus is a master-slave data transfer method in which the host controller operates as a master apparatus.
