METHOD FOR TRANSMITTING DIGITAL SIGNAL AND ITS PROCESSOR

摘要

PURPOSE:To improve the reliability of a transmission signal between recording and reproducing devices for a digital signal at the transmission of the signal by transmitting the output of a reproducing signal processing means through a recording signal processing means in an equipment on a transmitting side, and receiving the transmitted signal by a recording signal processing means through a reproducing signal processing means in the equipment on a receiving side. CONSTITUTION:Digital data 6a detected and corrected by a reproducing signal processing circuit 11a are inputted to a recording signal processing circuit 12a to add an additional signal such as an error correcting parity and a synchronizing pattern to the input signal 6a and the added signal is outputted to a reproducing signal processing circuit 11b on the recording side. The circuit 11b detects and corrects an error generated in a transmission line A at the time of transmission from a digital VTR 10a to a VTR 10b and outputs the corrected signal to a recording signal processing circuit 12b as an original digital signal 7b. The circuit 12b adds an additional signal such as an error correcting parity and a synchronizing pattern to the digital signal 7b sent from the circuit 11b and outputs the added signal to a magnetic recording/reproducing device 13b. The device 13 records a signal 8b outputted from the circuit 12b in a recording medium.
