摘要:
A satellite broadcast system and method, particularly useful for television signals, allows for local as well as nationwide broadcast service by allocating greater satellite resources to the more important local service areas. This is accomplished by broadcasting a non-uniform pattern of local service beams and designing the system to establish different service area priorities through factors such as the individual beam powers, sizes, roll-off characteristics and peak-to-edge power differentials. Frequency reuse is enhanced by permitting a certain degree of cross-beam interference, with lower levels of interference established for the more important service areas.

摘要:
An end-to-end global distribution system that can produce and deliver live content as well as pre-recorded content and other content, to commercial passenger aircraft via a satellite and ground-based infrastructure. The content can include live television, pre-recorded content, advertisements as well as other content such as software applications, internet material, etc. The delivered content can be tailored based on distribution criteria such as airline, aircraft, origin and destination, flight number, cabin class, and others. Such system can be advertiser-supported and include targeted and distribution specific advertisements. Furthermore, access to the content can be controlled by various conditional access parameters at the server level, to various aircraft zones, and at the passenger level.
摘要:
The new satellite communications repeater test method allows multiple transponders to be tested from a single ground test station. The satellite's receive antenna is aligned with the ground station antenna and uplink test signals are transmitted to the satellite. The uplink test signal is converted to a corresponding downlink signal which is distributed to the transponders fed by the receive antenna. Prior to transmission from the satellite, the amplified downlink signals are sampled and combined and/or switched into a single path having a frequency spectrum which includes the frequency bands of the sampled downlink signals. The combined signal is transmitted to the ground test station from a wide angle transmit antenna. The received downlink signals are measured and stored for later processing to validate the operational characteristics of the transponders. In an alternative embodiment, the sampling and combining matrix includes switches for selecting the sampled signals to be combined.
