Patent ID: 7403139

Claim:
An electronic apparatus comprising: a communication section for requesting an external apparatus to transmit a digital data stream including a video signal and/or an audio signal which are continuous relative to a time axis, and for receiving the digital data stream transmitted in response to the request, a sample rate converter for rate-converting a received video signal and/or audio signal; and an output section for outputting the video signal and/or audio signal which are rate-converted and demodulated into a continuous signal, wherein, in such a state that a synchronization clock for the video signal and/or audio signal is not outputted from said electronic apparatus, said sample rate converter changes a number of samples to be outputted in the case that a predetermined volume of the video signal and/or audio signal is rate-converted according to a constant sampling clock and outputted, based on: (a) time information and/or data volume of the video signal and/or audio signal processed or outputted by the electronic apparatus; and (b) time information and/or data volume of the video signal and/or audio signal, which are transmitted from said external apparatus or transmittable from said external apparatus to said electronic apparatus.
