Abstract
A picture control device configured to convert and output a bit-rate of an input picture data stream having an input bit-rate, includes: a first decoder configured to decode the input picture data stream; an encoder configured to encode the output of the first decoder with a plurality of converted bit-rates; an output unit configured to output the picture data encoded with a first bit-rate by the encoder, for recording; a second decoder configured to decode the same picture data encoded at a second bit-rate by the encoder; and a control unit configured to determine the second bit-rate based on the first bit-rate.
