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.
Claims14
A recording device configured to record an input content data in a storage unit and convert a bit-rate of an input content data having an input bit-rate and output a content data having a converted bit-rate, the recording device comprising:
- a decoder configured to decode the input content data so as to produce a first decoded content data;
- an encoder configured to encode the first decoded content data so as to produce a first encoded content data having a first bit-rate lower than the input bit-rate;
- an output unit configured to output the first encoded content data having the first bit-rate to an external recording medium;
- and wherein
- in a case where the first encoded content data is outputted to the external recording medium by the output unit,
- the encoder encodes the first decoded content data so as to produce a second encoded content data having a second bit-rate lower than the input bit-rate,
- the decoder decodes the second encoded content data having the second bit-rate so as to produce a second decoded content data, and
- the output unit outputs the second decoded content data to a display unit.
A recording method for recording an input content data in a storage unit and converting a bit-rate of input content data having an input bit-rate and outputting a content data having a converted bit-rate, the method comprising:
- decoding the input content data so as to produce a first decoded content data;
- encoding the first decoded content data so as to produce a first encoded content data having a first bit-rate lower than the input bit-rate;
- outputting the first encoded content data having the first bit-rate to an external recording medium;
- and wherein
- in a case where the first encoded content data is output to the external recording medium,
- encoding the first decoded content data so as to produce a second encoded content data having a second bit-rate lower than the input bit-rate;
- decoding the second encoded content data having the second bit-rate so as to produce a second decoded content data;
- and
- outputting the second decoded content data to a display unit.
