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.

A system and method for communicating content to a user device includes a head end that communicates a plurality of upcoming content metadata that includes a content title to the user device. The user device displays the upcoming content metadata and selects at least one upcoming content metadata from the plurality of upcoming content metadata to form selected data. The user device communicates the selected data to the head end. The head end adjusts head end communication parameters for the content associated with the selected data based on the selected data and communicates the content to a user device based on the head end communication parameters.
