Abstract:
1. A method for processing multimedia information in a satellite multimedia broadcasting terminal, the method comprising: obtaining and storing, by a first processor, first pilot channel information from a pilot channel transmitted by a satellite multimedia broadcasting station; determining whether the first pilot channel information is different from previously obtained second pilot channel information by comparing the first pilot channel information to the second pilot channel information; transferring the first pilot channel information to a second processor only when the first pilot channel information is determined to be different from the second pilot channel information, wherein the first pilot channel information is not transferred to the second processor when the first pilot channel information is the same as the second pilot channel information; updating, by the second processor, the second pilot channel information upon receiving the first pilot channel information from the first processor, wherein the second pilot channel information is not updated when the first pilot channel information is the same as the second pilot channel information; and utilizing the updated pilot channel information in a code division multiplexing (CDM) demodulator to process the multimedia information via at least one broadcast channel decoding unit, wherein the pilot channel information is required for operation of the terminal, the pilot channel information comprising information regarding analysis of reception signals and synchronization detection of spread signals, and CDM channel configuration information, and wherein comparing the first pilot channel information to the second pilot channel information comprises comparing a version number of the first pilot channel information to a version number of the second pilot channel information.
