Abstract
An electronic apparatus reads a digital data stream including a video signal and/or an audio signal outputted from an external apparatus according to a transmission clock different from a clock for the data stream, and outputs the video signal and/or audio signal without causing any discontinuity. The electronic apparatus includes a sample rate converter that rate-converts a predetermined volume of the audio signal in synchronization with a constant sampling clock, and changes a number of samples to be outputted, based on a data volume of an audio signal outputted by the electronic apparatus and a data volume of an audio signal transmitted from the external apparatus or transmittable from the external apparatus to the electronic apparatus.
