Abstract:
1. A recording device of a system that performs transcoding on a plurality of coded pieces through distributed processing between the recording device and an auxiliary device, a sequence of the plurality of coded pieces forming a digital stream which is played back along a playback time axis, the recording device comprising: a transcoding unit operable to transcode at least coded pieces forming, from among a former half and a latter half of the digital stream obtained by dividing the digital stream at a predetermined point on the playback time axis, the former half of the digital stream; a transmission unit operable to transmit, to the auxiliary device, coded pieces which form the latter half of the digital stream; and a writing unit operable to write results of the transcoding performed by the transcoding unit onto a single recording medium, wherein, for results of transcoding the former half and simultaneously with the transcoding unit transcoding one of the coded pieces of the former half, the writing unit writes a result of the transcoding unit transcoding a coded piece immediately preceding the of the coded pieces in the digital stream onto the single recording medium, and wherein, for results of transcoding the latter half and after the writing unit writing all of the results of the transcoding unit transcoding the former half onto the single recording medium, the writing unit (i) receives results of the auxiliary device transcoding the latter half from the auxiliary device and (ii) writes the received results of the auxiliary device transcoding the latter half onto the single recording medium.
