摘要： A method and apparatus for synchronization of a moving picture experts group (MPEG) transport stream, which minimizes an initial delay are provided. A packet synchronization unit and a mode of the packet synchronization unit to are initialized to “0”. Values of sync words are stored by shifting values of a sync word register when the sync words have been received and the received sync word is compared with predetermined code words As a result of the comparison, a determination is made as to whether a bit difference between the sync words and the predetermined code words exceeds a predetermined threshold value. A verification is then made as to whether all bits of the sync words correspond to all bits of the predetermined code words, when it is determined as a result of the determination that the bit difference is less than or equal to the predetermined threshold value and the MPEG transport stream is descrambled before returning to step of storing values of sync words by shifting values of a sync word register.

摘要： An apparatus and method are provided for decoding data of first and second control channels in a mobile communication system providing multi-media services including voice and data services. The apparatus includes an input section for selectively outputting data stored in first and second control channel input sections which store data of the first and second control channels, respectively, a viterbi decoder core block for outputting a decoding result by decoding the data output from the input section, an output section for storing the decoding result output from the viterbi decoder core block in one of first and second control channel output sections, and a controller for setting a second control channel delay flag, which is a signal for delaying data decoding for the second control channel, as “on” in order to perform data decoding for the first control channel if decoding start signals of the first and second control channels are simultaneously input.
