Abstract:
1. A picture control device configured to convert a bit-rate of an input picture data stream having an input bit-rate and output a picture data stream with a converted bit-rate, said picture control device comprising: a first decoder configured to decode said input picture data stream so as to produce a first decoded picture data stream; an encoder configured to encode the first decoded picture data stream so as to produce a first encoded picture data stream having a first bit-rate lower than said input bit-rate and a second encoded picture data stream having a second bit-rate lower than said input bit-rate; a first output unit configured to output the picture data of the first encoded picture data stream corresponding to the first bit-rate to a connected recording medium; a control unit configured to, in an event that the first encoded picture data stream has been output to the connected recording medium by the first output unit, control the encoder to encode the first decoded picture data stream so as to produce the second encoded picture data stream having the second bit-rate, wherein the control unit determines said second bit-rate based on said first bit-rate; a second decoder configured to decode the second encoded picture data stream corresponding to the second bit-rate so as to produce a second decoded picture data stream; and a second output unit configured to output the picture data of the second decoded picture data stream to a display unit.
