Abstract: A multimedia data system comprising a synchronization unit. The synchronization unit receives a demodulated bitstream, checks whether a FAW pattern corresponding to a candidate of the bitstream exists, checks whether an additional information corresponding to the candidate of the bitstream is valid when the FAW pattern exists, determines a hit weighting corresponding to the candidate according to the checking result, determines whether the hit weighting meets a criterion and outputs a synchronization signal when the hit weighting meets the criterion.

Abstract: A receiving system for audio processing includes a first demodulation unit and a second demodulation unit. The first demodulation unit is utilized for receiving an audio signal and generating a first demodulated audio signal. The second demodulation unit is utilized for selectively receiving the audio signal or the first demodulated audio signal according to a setting of a television audio system which the receiving system is applied, and generating a second demodulated audio signal.

Abstract: The invention provides a multiple audio channel bass management method for an audio system comprising multiple processing units, wherein each processing unit receives a corresponding channel signal and outputs to a speaker, the method comprising: high pass filtering a first channel signal to drive a first speaker and low pass filtering the first channel signal to generate a first low frequency signal if the first speaker is not a full range speaker; combining a first bass information signal and the first channel signal to drive the first speaker if the first speaker is a full range speaker, wherein the first bass information signal is derived from the low frequency signal generated by other processing unit.

Abstract: A method for detecting a program deviation period during a television broadcast having a main audio program and a secondary audio program includes: receiving the main audio program; receiving the secondary audio program; calculating a similarity value between the main audio program and the secondary audio program within a candidate period; and determining whether the candidate period is the program deviation period according to the calculated similarity value.

Abstract: A method and system for audio decoding. A set of channel remapping equations and channel remapping coefficients are first provided. Audio samples are received, which comprise a specific number of input channels In#. The audio samples are then processed according to the channel remapping equations and channel remapping coefficients, thereby converting the input channels In# to a specific number of output channels Out#.
