RECORDER, RECORDING METHOD AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a variable bit rate video encoder, a video recorder and a recording medium that can obtain a code amount adapted to a video signal and attain processing in real time. SOLUTION: A degree of a difficulty of encoding a video signal in a given period of time is detected and converted with a specific transform characteristic for producing an allocated amount of codes. The video signal is quantized and variable length encoded to produce a second coded data. A quantization parameter is determined, so that the difference between the code length of the second coded data in the given period of time and the allocated amount of codes becomes small.
