ABSTRACT:
A recording and reproducing apparatus which receives character broadcasting information transmitted via a vertical blanking period of audio/video signals. The apparatus detects certain information from the received data, including a prefix portion and character information. The character information is screened for desired information which is then separated from the remaining broadcasting information based on the detected information, such as the prefix portion. The separated data is then recorded in a separate area on the recording track. Video data is recorded in a first area and audio data is recorded in a second area on the recording track. The character broadcasting information is reproduced by inserting the reproduced desired character information into the vertical blanking period of reproduced video data.
