<p>N pieces of encoders 21, 22, ... 2n read parameter information PAR.#1, #2, ... #n in advance for each of n pieces of programs, prog.1, 2, ... n, and make a controller (3) estimate the information, difficulty, concerned with the degree of difficulty of encoding at the time of encoding an image, and also compression-encode the above n pieces of programs on the basis of the target encoding rate that the controller (3) has computed based on the above parameter information. The controller (3) computes the quantity of allotted codes, target_rate#1, #2, ... #n, in every program from the above parameter information PAR.#1, #2, ... #n. A multiplexer (4) multiplexes the streams #1, #2, ... #n that the encoders 21, 22, ... 2n have encoded, according to the above quantity of allotted codes, target_rate#1, #2, ... #n.</p> |
