  • Patent number: 7436898
    Abstract: An integrated circuit (IC) card capable of a high-speed data transmission to/from a data transmission apparatus having low processing capability. A controlling section generates a data packet by adding management information including information regarding a data length of the data packet, and divides the data packet to generate data blocks. The data length of the data block is designated from the data transmission apparatus. When the data blocks which compose the single data packet are sent to the transmission apparatus a communicating section sends an interrupt signal to the data transmission apparatus if the data block including the management information is to be sent, and does not send the interrupt signal to the data transmission apparatus if a data block not including the management information is to be sent.

  • Publication number: 20070177736
    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.
