The present invention relates to a dubbing recording control apparatus and method using a digital interface, for example, by selecting and specifying some recording intervals in a memory card included in a digital camcorder connected and connected via an IEEE 1394 interface, The present invention relates to a dubbing recording control apparatus and method using a digital interface for allowing dubbing recording in a recordable DVD (eg, DVD-R) included in a DVD recorder.

In general, DVD-Recorder and Digital Camcorder, which can record and store high-quality video data and high-quality audio data for a long time, are widely used and commercialized. In the DVD recorder, A / The V data stream is recorded and stored in a recordable optical disc, for example, a rewritable DVD (DVD-RW, DVD + RW, DVD-RAM) or a write-once DVD (DVD-R, DVD + R) or the like.

In the digital camcorder, video data of a subject photographed by a camera is recorded and stored on a digital video tape, or recorded on a memory card or the like. In an advantageous memory card, examples of recording and storing A / V data streams are rapidly increasing.

Meanwhile, the digital camcorder and the DVD recorder may be connected and connected through an IEEE 1394 interface. For example, when the DVD recorder performs a dubbing recording operation at the request of the user, the digital camcorder and the DVD recorder may be connected to the digital camcorder. Through the interface, the A / V data stream recorded on the memory card is read and reproduced, the A / V data stream is received, and recorded and stored on an optical disc (eg, DVD-R) inserted in the apparatus.

Accordingly, the user having the digital camcorder and the DVD recorder can perform the above dubbing recording operation to record and store the A / V data stream recorded on the memory card on the optical disc. For example, as the optical disc, a recordable DVD-R (DVD-R) having a relatively low price is mainly used.

However, when only data recorded in some recording sections of the memory card of the digital camcorder is to be recorded on the optical disc of the DVD recorder, the user can directly confirm the A / V data reproduced by the memory card. There is a problem in that the recording operation of the recorder is stopped so that only a part of the recording section is recorded on the optical disc.

In addition, when the A / V data reproduced in the memory card is recorded on the optical disc, when the remaining capacity of the optical disc becomes insufficient, the data recording operation is stopped, so that a normal dubbing recording operation is not possible. In a state where the data recording operation is stopped, a problem arises in that data recorded on the memory card is unnecessarily reproduced.

Accordingly, the present invention was created to solve the above problems, and for example, a user selects some recording sections of a memory card included in a digital camcorder through an IEEE 1394 interface through an OSD image. In addition, the recording capacity of the recordable DVD included in the DVD recorder can be compared with the data capacity to be read out and reproduced in the recording section of the DVD recorder. Accordingly, after performing a dubbing recording operation for the partial recording section or outputting an error message and displaying the error message, the digital interface may be used to selectively perform the dubbing recording operation according to the user's selection. It is an object of the present invention to provide a dubbing recording control device and method.
