Patent number: 8126318Abstract: A system, which minimizes a time delay caused by one device being unable to access a recording medium until access by another device ends, when transcoding is performed by distributed processing, includes a main device transcoding each coded piece allocated to itself from among a plurality of coded pieces of a digital stream, and writing a transcoding result onto the recording medium, in a pipeline. While the recording device is performing the transcoding and the writing, an auxiliary device transcodes each coded piece allocated to itself one by one. Having completed the transcoding of all coded pieces allocated to itself, the auxiliary device transmits its transcoding results to the recording device and has the recording device write the transcoding results onto the recording medium which is a copy destination.Type: GrantFiled: August 30, 2005Date of Patent: February 28, 2012Assignee: Panasonic CorporationInventors: Masao Nonaka, Yoshiaki Iwata, Yoichi Yamamoto, Motoji Ohmori
