ABSTRACT:
A digital AV signal processing apparatus includes a buffer for storing digital data input to the digital AV signal processing apparatus, and outputting the digital data as output digital data, a D/A converter for converting the output digital data to analog data, a voltage-controlled oscillator for generating a clock signal to control a conversion rate of the D/A converter, and a voltage-controlled oscillator controller for detecting a data amount of the digital data stored in the buffer, and controlling a frequency of the clock signal based on a deviation in the detected data amount from a first predetermined value and a time integral of the deviation value.
