<p>A printed circuit board intended to be placed within a card slot of a personal computer (102) that allows the personal computer (102) to receive information directly from a satellite communication network. An adapter card (124) operates in slave mode to a CPU (120) of the personal computer (102). The CPU (120) receives demodulated signals from a demodulator (130) of the adapter card (124) via a bus interface (134) on the adapter card (124). The CPU (120) also receives status information for the demodulator (130) and a tuner (132) and controls the operations of the demodulator (130) and tuner (132) via the bus interface (134). A DC-DC converter (136) receives power from a power supply (126) for the adapter card circuitry. Moreover, the DC-DC converter (136) powers a low noise block (LNB 112) of an antenna (110) of the satellite communication network.</p> |
