FUNCTION MODULE CARD, HOST DEVICE, AND CONTROL METHOD THEREOF

摘要

A digital broadcasting receiver apparatus is provided with a functional module card that includes a digital broadcasting reception function and a host apparatus to which the functional module card can be attached as an optional unit. The functional module card and the 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 TS 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. The host apparatus includes a host controller that communicates with the card controller, an input and output section, and a decoder and descrambler. A data transfer method for transferring data between the card controller and the host controller is a master-slave first data transfer method in which the host controller operates as a master apparatus. A data transfer method for transferring the data between the tuner section and the decoder and descrambler is a second data transfer method in which the TS clock is a transfer clock.
