PURPOSE:To simplify the reproducing by forming a video format signal with a control signal including user's data, a sound signal and a picture signal, recording the format signal and trasferring the user's data via a series line in a real time. CONSTITUTION:A digital data signal including a video signal and a sound data subject to time axis compression by a buffer memory 81, a digital data, a control data identifying one of inserted positions of a picture data and a control signal including the user's data representing choices are inputted respectively to a switching circuit 82 in a recording system. The selecting operation of the circuit 82 is controlled by a timing signal generator 83 and the write/read of the memory 81 is controlled by the generator 83. Various timing signals are generated at the generator 83 by using an external input signal. Then an error correction circuit 4 uses a control data in the control signal in reproduction so as to discriminate picture information and the digital data and user's data is reproduced via a series llne while being transferred in a real time. |
