Title:
DATA PROCESSING DEVICE, DATA PROCESSING METHOD, AND RECORDING/REPRODUCING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2008/023763
Kind Code:
A1
Abstract:
It is possible to provide a data processing technique capable of reducing the
processing time for rate conversion dubbing associated with video/audio data.
For example, in a data processing device of a recording/reproducing system
having an AV decoder and an AV encoder, when a rate conversion dubbing of the video/audio
data is started, firstly, decoding of the first data (DA) is started in the AV decoder.
When the decoding of the data (DA) is completed, the AV decoder issues a control
signal. Upon reception of the control signal, the AV encoder immediately starts
encoding of the decoded data (DA) which has been decoded. Next, when encoding
of decoded data (DA) is completed in the AV encoder, the AV encoder issues a control
signal. Upon reception of the control signal, the AV encoder immediately starts
decoding of the next data (DB). By performing the aforementioned control, it
is possible to reduce the processing time for the rate conversion dubbing.
