摘要： In a video signal recording/reproducing apparatus, a video signal is subjected to bit rate reduction including a variable length processing to obtain a coded data. The coded data is separated into basic data which shows a basic construction of video image and has a fixed data length and additional data which shows detailed information of the video image and has a variable data length. In recording the coded data containing basic data and additional data on a recording medium, the basic data is recorded in one region on the recording medium and the additional data is recorded continuously in a region other than the basic data recording region, by which both data are recorded in separated regions on the recording medium.

摘要： Digital video signals are divided in blocks, maximum and minimum values of each block are extracted, and a frequency distribution of one frame period of a dynamic range in each block is detected. The coding condition is determined by the frequency distribution and a predetermined N kinds of characteristic tables, and by determining only one characteristic table, the signal obtained by subtracting the minimum value of each block from the digital video signals of each block is coded in variable length according to the dynamic range of each block. The characteristic table shows the relationship of the distortion or the number of quantization bits between the original signal and decoded signal after coding and decoding with respect to the dynamic range of digital video signal in each block, and the picture quality of decoded image is set as a parameter.
