摘要： A digital information recording-reproducing apparatus which records and reproduces a digital information signal transmitted together with an additional information includes a discriminator which discriminates a type of the digital information signal based on the additional information, a recorder which generates control information based on the additional information, adds the control information to the digital information signal, and records the digital information signal having the control information added thereto, a reproducer which reproduces the recorded digital information signal recorded by the recorder, and a controller which controls reproduction based on the control information. When the discriminator discriminates the type of the digital information signal as being a specific type and the digital information signal is recorded by the recorder, the reproducer reproduces the digital information signal.

摘要： A digital information recording-reproducing apparatus is disclosed, in which a signal temporally compressed to 1/n and transmitted is encoded for recording by a recording encoder. The rotation speed of a rotary drum is set at R.sub.1, and the running speed of a magnetic tape at V.sub.1. The signal encoded is recorded on the magnetic tape by magnetic heads. At the time of reproduction, the rotary drum is driven at a speed m/n times faster than for recording, and the magnetic tape is run at a speed 1/n times faster than for recording. The signal reproduced by the magnetic heads is decoded and restored into the original digital information signal by a reproducing decoder. As a result, there is provided a recording-reproducing apparatus having the function of time-base expansion with a reduced recording time applied to a system for transmitting and recording the software information of video or the like through radio wave or cable.

摘要： An offset compensation circuit for compensating a DC offset which occurs in a circuit line including an A/D converter or an A/D and D/A converter in which not only the polarity bit of digital data but also information concerning the amplitude of an analog input signal are applied to an integrator to precisely compensate an offset voltage in a circuit line. The level of a proper offset compensation voltage is provided even when an input analog signal such as a music signal is absent, and when an A/D and D/A converter is provided which can perform both A/D conversion and D/A conversion the DC offset can be precisely compensated shortly after the change of the mode from D/A conversion to A/D conversion.
