摘要： This invention provides a data signal extraction apparatus that accurately extracts data from a data signal that is serially transmitted even when phase shift or the like occurs. According to this apparatus, a phase shift amount calculation circuit 13 calculates a phase shift amount S13, then a correction amount calculation circuit 14 calculates a correction amount S14 on the basis of the phase shift amount S13, an extraction interval correction circuit 10 corrects an extraction interval value S9 on the basis of the correction amount, and an extraction pulse generation circuit 11 generates an extraction pulse S11 on the basis of a corrected extraction interval value S10, thereby extracting data from a binary signal S8 on the basis of the extraction pulse.

摘要： A video signal processor is used to receive programs in the form of a composite video signal which incorporates a video broadcast channel, a main audio channel and an additional audio channel. The main audio channel may carry a standard audio track for the program while the additional audio channel carries a different audio track, such as dialogue in a foreign language, DVS audio track, or a modified audio track that has been changed from the main audio track slightly. The video signal processor selects one of the audio tracks as the active audio track based on the contents of the additional audio channels and/or a viewers' preferences. The video signal processor may be a stand-alone device, or may be incorporated into a TV receiver, VCR, DVD player, etc.
