Abstract

A portable data storage device receives data from a digital broadcast signal receiver that is adapted to separate the data from a digital broadcast signal. The portable data storage device includes a first transceiver that communicates with a second transceiver associated with the digital broadcast signal receiver and further includes a memory for storing the received data. A processor disposed within the portable data storage device controls the storage of the data and further causes a data request signal to be generated and transmitted to the digital broadcast signal receiver. A controller disposed within the digital broadcast signal receiver responds to the data request signal by causing the data separated from the digital broadcast signal to be transmitted via the second transceiver to the portable data storage device. The portable data storage device further includes a data communication port for transferring the data to a personal computer.
