Digital recording/reproducing apparatus

摘要

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 (3), processor (4) and a converter (9) provided between the input unit (3) and processor (4). The input unit (3) accepts audio data having a specific field frequency (24 frames/sec or the like) and arranged in a specific format, and make baseband processing of the audio data. The processor (4) 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. The converter (9) converts the sampling frequency of the audio data at a ratio between the specific and basic field frequencies while adapting the specific format to the basic one. The processor (4) operates with a clock corresponding to the converted sampling frequency to make error-corrective encoding.
