PURPOSE:To enable digital dubbing of both two sampled data series by adding pseudo data to one of two sampled data series by the prescribed amount, by expressing two data series with a product of a common value and an unique value and by changing an unique value term in accordance with smapled frequency. CONSTITUTION:In order to record and reproduce both data series of a digital audio disk (DAD) device and a digital audio tuner (DAT) device, it is necessary that the number of remaining frames is made variable, and each vavue shall be an integer. Therefore pseudo data are added to audio data of the DAT device. In terms of the DAD device, for instance, pseudo data do not be added to audio data, and the number of frmaes is assumed to be F=245 frames. In terms of the DAT device, pseudo data are added by two words for 1,600 words, thereby being F=267 frames. The value of F is changed in accordance with the device, that is, sampled frequency; therefore data series generated in two types of sampled frequency can be recorded and reproduced. |
