Abstract
An image signal recording apparatus achieves an orthogonal transform and a compression coding on image data so as to record the resultant data in a recoding medium. There is disposed a selector to select a compression ratio for the compression coding of the data, namely, the compression ratio is selectable. The selected compression ratio data is recorded in the recording medium together with the image data. A playback apparatus reads from the recording medium the compression ratio data together with the image data undergone the compression coding so as to decode the image data by use of the compression ratio data. In consequence, according to these apparatuses, the compression ratio can be arbitrarily set. In addition, the image signal recording apparatus generates recording codes associated with the amounts of the image data and the audio data so as to write the codes in the recording medium. The recording codes are read from the recording medium, so that the remaining amount of the recording medium available for the recording operation is displayed.
