摘要：
An information transmission system using data compression and/or error detection includes an information compression circuit for compressing digital information to generate compressed information. A record/reproducing device is provided for recording the compressed information on a recording medium, and reproducing the compressed information from the recording medium. Transmission circuitry is provided for transmitting the compressed information reproduced from the record/reproducing device to a transmission channel without expanding the compressed information. An information expansion circuit is then provided for expanding the compressed information which has been transmitted through the transmission channel in order to reproduce the digital information.
