Functional module card for transferring digital broadcasting signal using a clock generated based on a synchronous signal extracted from a received data signal
First Claim
1. A functional module card comprising:
- a communication section for communicating with a host apparatus via a plurality of connection lines; and
a broadcasting signal receiver section for receiving a digital broadcasting signal, generating a data signal of the digital broadcasting signals, and generating a clock for transferring the data signal based on a synchronous signal extracted from the data signal,wherein said communication section includes;
a first data transfer mode for transferring data via a data bus of connection lines selected from the plurality of connection lines; and
a second data transfer mode for transmitting the data signal and the clock for transferring the data signal, respectively, to the host apparatus via a first connection line and via at least one additional connection line other than the first connection line, the first connection line and the at least one additional connection line being selected from the connection lines which transfer the data in the first data transfer mode, andwherein, in the second data transfer mode, said communication section transfers the data signal synchronously with the clock for transferring the data signal.

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.
