  • Satellite signal switching system
    Patent number: 11019401
    Abstract: A content signal switching controller receives first signal information about a first content signal provided by a first satellite antenna and received by a trunk distribution system. The first signal information indicates the quality of a satellite signal that is received by the first satellite antenna and that is converted to the first content signal. The content signal switching controller receives second signal information about a second content signal provided by a second satellite antenna. The second signal information indicates the quality of the satellite signal that is received by the second satellite antenna. In response to the content signal switching controller determining that the first signal information and the second signal information satisfy a first signal switching condition, a content signal switch instruction is provided to a switch device to switch the trunk distribution system from being provided the first content signal to being provided the second content signal.
