Abstract
In a system including a still video camera and a playback device capable of being connected thereto, the playback device stored track information (such as data representing the field/frame recording and the envelope peak position) detected in a playback operation in a memory thereof corresponding to a track number. When the power of the playback device or the like is turned off, the track information is transferred from the playback device to the camera side and is stored in a memory of the camera side. When the playback device achieves thereafter a playback operation, the track information is again transferred to the playback device so as to be used for the playback operation. The track information can also be used in an erase operation on the camera side or in the playback device. In addition, track information used in a recording operation of the camera is stored in a memory thereof corresponding to a track member. When the playback device is connected to the camera and a mode thereof is changed over to a playback mode, the track information is transferred from the camera to the playback device, thereby storing the track information in a memory of the playback device. The track information is used when the playback device conducts a playback operation.
