摘要： An apparatus and method for processing content signals received from a plurality of different, and possibly dissimilar, signal sources, such as different satellite networks, and providing a display based on the content of those signals. The apparatus includes a tuner/demodulator for receiving content signals and demodulating the received content signals as programming bitstreams, and one or more access control devices for descrambling any conditional access present in the demodulated programming bitstreams. The apparatus further includes a processor, such as a system chip, which is responsible for all command and control functions. The system chip evaluates conditional access to determine whether the bitstream needs decryption, descrambling, or both, and processes a bitstream from one of the multiple signal sources for display on a suitable output device.

摘要： An antenna alignment apparatus and alignment method is used to effectively position an antenna used in a satellite communication system on the satellite orbital arc, and to ensure that a proper antenna polarization is achieved during installation or alignment of a remote station antenna. The apparatus includes a secondary receiving device mounted on the feed arm of the antenna at a specified distance from the primary receiving device located on the primary plane of the antenna. An antenna using this system and method may be properly aligned on the orbital arc using only simple receiving equipment.

摘要： An approach is provided for distributing multi-media information from a satellite broadcast system. A hub receives a signal from the satellite broadcast system, wherein the signal represents video information and audio information associated with multiple broadcast channels. The hub centrally demodulates and decodes the received signal for distribution to one of a number of access point devices. According to one embodiment of the present invention, the decoded signal represents uncompressed video and audio information corresponding to one of the broadcast channels. The access point devices convert the received decoded signal for output respective displays (e.g., television sets). The hub can also be equipped with an interface to provide access to a public data network, such as the global Internet. Further, the hub can be supplied with a digital video recording capability.
