ABSTRACT:
Based on a digital recorder/player taken as a basic apparatus and which accommodates a field frequency of 60 fields/sec or a frame frequency of 30 frames/sec, an apparatus is implemented to record or reproduce source video and audio signal originated from the basic apparatus and whose frequency is different from the field or frame frequency. The apparatus includes an input unit, a processor, and a converter provided between the input unit and the processor. The input unit accepts audio data having a specific field frequency and arranged in a specific format, and make baseband processing of the audio data. The processor is designed to process audio data having a basic field frequency (60 fields/sec) and arranged in a basic format. It operates with a clock corresponding to the sampling frequency to make error-corrective encoding of the audio data adapted to the basic format.
