Summary:PURPOSE:To attain high definition and high picture quality by connecting a band compression encoder in parallel with a video recording processing circuit and a band compression decoder in parallel with a reproduction processing circuit via a selector switch. CONSTITUTION:In selecting the band compression mode by selector switches 2a-2d, a video input signal uses the band compression encoder 4 to be compressed into nearly 1/2 and the compressed video signal is recorded on a video tape by a video recording part of the VTR 5. In selecting the band compression mode by the selector switches 2a-2d at reproduction, the video reproducing signal obtained by the reproduction section of the VTR 5 is expanded into nearly twice band by the band compression decoder 7. As a result, the video input original signal to which resolution is improved is reproduced. In selecting the normal mode by the selector switch, the signal is recorded by the VHS, 8mm or the beta system and reproduced.
