    Abstract: An apparatus and method for processing satellite signals is provided. A switch receives an input signal having a predetermined frequency range, the predetermined frequency range including at least two frequency sub-bands. A first diplexer is connected to a first output of the switch and generates a first filtered signal including a first frequency sub-band and a second frequency sub-band and a second filtered signal including a third frequency sub-band. A second diplexer is connected to a second output of the switch and generates a third filtered signal including the first frequency sub-band and a fourth filtered signal including the second frequency sub-band. A controller activates the switch to operate between a first mode and a second mode. In the first mode, the switch provides the input signal to the first diplexer to generate the first and second filtered signals, the first diplexer provides the first filtered signal to the second diplexer to generate the third and fourth filtered signals from the first filtered signal, the second filtered signal being provided to the controller to derive a first type of data therefrom and the third and fourth filtered signals being provided to the controller to derive a second different type of data therefrom. In the second mode, the switch provides the input signal to the second diplexer to generate the third and fourth filtered signals from the input signal, the second diplexer provides the third and fourth input signal to the controller to derive the second different type of data therefrom.

    Abstract: In one form, a multi-chip module for a multi-mode receiver includes an MCM substrate and first and second demodulator die. The MCM substrate has first and second satellite input ports, first and second terrestrial/cable input ports, and first and second transport stream ports. The first demodulator die has a satellite port coupled to the first satellite input port of the MCM substrate, a terrestrial/cable port coupled to the first terrestrial/cable input port of the MCM substrate, and first and second transport stream ports coupled to the first and second transport stream ports of the MCM substrate. The second demodulator die has a satellite port coupled to the second satellite input port of the MCM substrate, a terrestrial/cable port coupled to the second terrestrial/cable input port of the MCM substrate, and first and second transport stream ports coupled to the first and second transport stream ports of the MCM substrate.

    Abstract: The present invention is intended to permit both real-time display of a picture represented by a non-compressed video signal on a television and display of a picture represented by a compressed video signal at any desired time by simultaneously transmitting the compressed video signal and non-compressed video signal via one interface. An STB packetizes a compressed video signal, and multiplexes the compressed video signal and a blanking signal combined with a non-compressed video signal. Thus, both the video signals are transmitted simultaneously. A picture represented by the non-compressed video signal is displayed on a television in real time. The compressed video signal is stored in a storage medium incorporated in the television, read at any user's desired time, and decoded so that a picture represented by the compressed video signal can be viewed at the user's desired time.
