Patent ID: 7610427

Claim:
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, and wherein, in the second data transfer mode, said communication section transfers the data signal synchronously with the clock for transferring the data signal.
