Abstract: Letting fp be the frequency of a pixel clock, fs be the audio sampling frequency, and fa be the frequency of an audio clock to be reproduced, fa=384 fs=(N/M)fp, where N and M are frequency dividing ratios between the pixel clock and the audio clock of a frequency corresponding to the audio sampling frequency. When fs=48 kHz, M=27000 and N=18432, and when fs=44.1 kHz, M=30000 and N=18816. A VCO control unit detects a change in the audio sampling frequency fs from a control voltage Vctl output from a loop filter or from the frequency fo of an output clock of an oscillating unit, and then selects one of at least two VCOs.

Abstract: An AV signal transmission/reception apparatus and a digital signal transmission system and method. A reception apparatus and method that can reproduce an audio reference clock of a plurality of different frequencies from a video reference clock. A pixel clock is divided by a divider into a signal of a constant frequency for phase comparison by a phase comparator. A sample frequency (Fs) decoder determines division ratio information based on Fs information representing the frequency of an audio clock transmitted from a transmission unit. The division ratio information is supplied to a first variable divider and a second variable divider. As a result, even if the frequency of the audio clock changes, the oscillation frequency of the a VCO unit can be kept constant, and the second variable divider can output a signal of a constant frequency for keeping constant the frequency of the signal transmitted to the phase comparator.
