Abstract
Plural n number of encoders 2.sub.1, 2.sub.2 . . . 2.sub.n 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 2.sub.1, 2.sub.2 . . . 2.sub.n have encoded in correspondence with the allocation code quantities target_rate #1, #2 . . . #n.
