摘要：
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 to produce an allocated amount of codes. The video signal is quantized and variable length encoded to produce a second coded data. A quantizing parameter is determined so that a difference between a code length of the second coded data in the given period of time and the allocated amount of codes is minimized.
