Recording system recording received information on a recording medium
while reproducing received information previously recorded on the
recording medium
摘要:
A recording system performs a reproducing operation for previously recorded information without stopping a recording operation for information currently being received. A video signal is received from an external video-signal-supplying source via a communication channel. The recording system is connected to a display unit having a screen. A recording medium is provided on which the video signal is recorded. A recording unit automatically records the video signal currently being received on the recording medium when a recording start command is received while an image according to the video signal currently being received is being projected. A reproducing unit reproduces the video signal recorded on the recording medium when a reproducing start command is received. A controlling unit controls operations of the recording unit and the reproducing unit so that the reproducing operation on the video signal previously recorded on the recording medium and the recording operation on the video signal currently being received are performed at the same time, and thereby the video signal currently being received is recorded on the recording medium while an image is projected in accordance with the video signal previously recorded on the recording medium.
