ABSTRACT:
In a digital VTR, supplied digital video information is separated into 0th to second stage data by an information separating circuit (300) employing a hierarchical coding method. The 0th stage data are subjected to processes such as error correction as main information capable of roughly forming video signals by themselves. The first and second stage data are subjected to error correction and the like as subinformation forming details of the image. The main information and the subinformation are recorded on a magnetic tape such that the main information is recorded at the central portion of each recording track and the subinformation is recorded on both outer side portions of the recording track. During high speed reproduction, at least the main information is reproduced from the magnetic tape and rough video information is formed based on the reproduced main information.
