ABSTRACT:
A real-time image compression processor records on a CD or other recording media a compressed video signal which is compressively processed in a high recording efficiency at real-time as being reproduced by a VTR while preventing the image quality from being degraded. There are provided a first encoder for compressively encoding the video signal, and a second encoder for compressively encoding the signal obtainable by delaying such video signal for a given period of time. A parameter adjustment is executed for the second encoder in accordance with the compressed video signal obtained through the compressive encoding by the first encoder. The compressed video signal obtained by the second encoder is recorded on a recording medium.
