Abstract

At least one frame of image information of each recording unit composed of a plurality of frames is intraframe-coded, and remaining frames of image information are intraframe-coded to output coded image information. The coded image information is divided into first and second groups in the same frame, and decoding information is added to the divided coded image information of the first and second groups. The first group of divided coded image information with the decoding information added in the recording unit is recorded in a first recording area of a recording medium, and the second group of divided coded image information with the decoding information added in the recording unit is recorded in a second recording area of the recording medium. It is determined whether a start-of-record frame or end-of-record frame of coded image information to be recorded agrees with an intermediate frame in the recording unit of coded image information recorded on the recording medium, in an editing recording mode in which the coded image information is recorded in superposed relation to the areas of the recording medium in which the first group of divided coded image information and the second group of divided coded image information are recorded.
