Plural n number of encoders 21, 22 ... 2n carry out reading in advance of parameter information PAR. #1, #2 ... #n with respect to respective n number of programs prog. 1, 2 ... n to allow a controller 3 to estimate encoding difficulty related information "difficulty" when picture is encoded, and to compression-encode the plural n number of programs on the basis of target encoding rate that the controller 3 has calculated on the basis of the parameter information. The controller 3 calculates allocation code quantities target_rate #1, #2 ... #n every respective programs from the parameter information PAR. #1, #2 ... #n. A multiplexer 4 multiplexes streams "stream" #1, #2 ... #n that the encoders 21, 22 ... 2n have encoded in correspondence with the allocation code quantities targer_rate #1, #2 ... #n. <IMAGE> |
