Abstract

PURPOSE:To observe the presence of flaws and dust on tape, propriety of code constitution of digital data, and error correcting capability quantitatively, by making the device of the code constitution effective to the error. CONSTITUTION:Error signals EM, ES which indicate the presence of errors every 24 or 1 sample are produced from playback processors 13A-13D, and they are applied to an interchanger 16 together with the data to correct the error of the identifying signal of each block. Further, an error signal EK and the data are applied to a circuit 25 which performs error correction by the horizontal parity data. Further, an error signal EH and the data are applied to a circuit 26 which performs error correction by the vertical parity data. Next, an error signal EV and the data are applied to a signal processor 20 and the correction is made based on the signal EV.
