Functional module card for transferring digital broadcasting signal using two transfer modes

A host apparatus comprising:

• a communication section for communicating with a functional module card via a plurality of connection lines;
• and
• a broadcasting signal output section for inputting a data signal of a digital broadcasting signal and a clock for transferring the data signal, which are transmitted from said functional module card, for performing a predetermined processing on the data signal and the clock, and for outputting a resultant data signal and a resultant clock,
• wherein said communication section includes:
• a first data transfer mode for transferring data via a data bus of connection lines selected from said plurality of connection lines;
• and
• a second data transfer mode for inputting the data signal and the clock for transferring the data signal, respectively, to said host apparatus via one connection line and via at least one another connection line other than said one connection line, said one connection line and said at least one another connection line being selected from the connection lines which transfer the data in the first data transfer mode.

A method for controlling a functional module card including:

• a communicating step of communicating with a host apparatus via a plurality of connection lines;
• and
• a broadcasting signal receiving step of receiving a digital broadcasting signal, and generating a data signal of the digital broadcasting signal and a clock for transferring the data signal,
• wherein said communicating step includes:
• a first data transfer mode for transferring data via a data bus of connection lines selected from said 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 said host apparatus via one connection line and via at least one another connection line other than said one connection line, said one connection line and said at least one another connection line being selected from the connection lines which transfer the data in the first data transfer mode.
