Abstract: A method and apparatus for synchronizing multiple signals is provided. The method and apparatus utilize the timing information of one of the multiple signals as a reference clock for synchronizing multiple signals. The method and apparatus utilize selectively gating the clocks of the other signal processing chains in order to allow control by the reference clock.

Abstract: Apparatus and method for acquiring a program from a packetized signal in response to ancillary information included in the packetized signal. The packetized signal includes a plurality of program signals and ancillary information associated with the plurality of program signals. The apparatus includes means for identifying the ancillary information from the packetized signal, the ancillary information including master guide information for use in identifying and acquiring special guide information, and special guide information for use in acquiring program information associated with the plurality of program signals. The program signals may be acquired using identifier information that may be derived from the ancillary information. The apparatus includes means responsive to the ancillary information for acquiring a selected program from the packetized signal.
