发明名称 Digital transmission signal processing system and recording/reproducing system
摘要 A digital information transmitting, receiving and/or recording/reproducing system, provided with the digital information transmitting apparatus for transmitting the digital information to a transmission path, a receiving apparatus for receiving the transmitted digital information and a recording/reproducing apparatus for the recording received digital information to a recording media and reproducing therefrom. The apparatus includes a compressor which compresses the digital information, a transmission parity signal adder which adds a transmission parity signal to the output signal of the compressor in order to correct an error occurring in the transmission path, wherein the transmission parity signal is different from a record parity signal to be added at the recording apparatus and a transmitter which transmits the transmission parity signal added compressed digital information added by the transmission parity signal adder to the transmission path.
