Abstract
An object of the present invention is to provide methods for properly correcting a frequency of a standard clock, receiving apparatuses, reproducing apparatuses, and programs in broadcasting data receiving systems comprising a receiving apparatus and a reproducing apparatus, in which the broadcasting data received at the receiving apparatus is transmitted to a reproducing apparatus via bus.In the broadcasting data receiving systems stated above, when the receiving apparatus detects the broadcasting-side time information that reflects the encoding standard clock, the extraction of the broadcasting-side time information is transmitted in a form of status change signal to the reproducing apparatus via the dedicated line, and the content of the broadcasting-side time information is transmitted to the reproducing apparatus via bus. By this, the timing of the extraction of the broadcasting-side time information is immediately notified to a reproducing apparatus, and the correction of the decoding standard clock is properly carried out.
