Hereinafter, operation steps and operational effects of the recording apparatus and the method of the digital recording apparatus configured as described above will be described.

2 is an overall operation flowchart of the step-by-step recording method of the digital recording apparatus according to the present invention, and assumes that a DVD is mounted in the DVD drive 40.

First, when the user sets the reservation recording through the user interface 60, the microcomputer 70 determines whether a key signal corresponding to the reservation recording setting is input through the user interface 60 (S100). When the signal is input, the estimated recording capacity of the content set in the reserved recording is predicted before starting the scheduled recording of the corresponding content (S110).

Subsequently, the microcomputer 70 checks the free recording capacity of the DVD before recording to the DVD to determine whether the recording capacity is sufficient (S120), and if the DVD is a recordable disk, recording operation on the DVD. It performs (S121).

On the other hand, if the DVD is not a recordable disk, it is determined whether a recordable free recording capacity of the HDD exists to temporarily store the corresponding content on the HDD (S130). In order to secure the recording capacity for temporary storage, the recording title deletion step of automatically deleting the recording titles recorded on the HDD is entered (S200). The recording title deletion step deletes the recording titles already recorded on the HDD one by one. The operation of recording new content for reservation recording on the HDD is performed simultaneously, which will be described in detail with reference to FIG. 3.

In addition, if there is a recordable free recording capacity of the HDD, it is determined that the recording is possible in the HDD, and the recording operation is performed on the HDD (S140), and before the recording capacity of the HDD is used even during the recording operation on the HDD. Subsequently, the free recording capacity is checked to check whether the free recording capacity is sufficient (S150).

If the free recording capacity of the HDD is not sufficient in step S150, to enter the recording title deletion step of automatically deleting the recording title already recorded on the HDD in order to secure the free recording capacity for temporarily storing the content on the HDD ( S200), while recording the recording titles already recorded on the HDD one by one, the operation of recording the contents on the HDD is simultaneously performed.

On the other hand, if the free recording capacity of the HDD is sufficient in S150, the recording operation is continued on the HDD without performing the recording title deleting step, and all the contents set in the reserved recording are recorded in the HDD and the reserved recording is finished (S160). 70 displays a message prompting the user to copy data temporarily stored on the HDD to the DVD for a predetermined delay time, and if the user command for selecting a copy operation is not input even after the predetermined delay time has elapsed, the data temporarily stored on the HDD is stored on the DVD. The operation to end the operation disappears while the guide message to copy (S170).

This is to display a message to the user through a scenario provided by the user interface (UI) in order to store the contents recorded on the HDD on a DVD desired by the user so that the user has a delay time of confirming the management of the contents again. .

Subsequently, when the free recording capacity of the HDD does not exist or the free recording capacity of the HDD is not sufficient, the recording title deleting step (S200) for securing a recording capacity for temporarily storing the corresponding content on the HDD is described with reference to FIG. 3. Will be explained.

3 is an operation flowchart of a recording title deletion step of the digital recording device according to the present invention.

First, before deleting a recorded title recorded on the HDD, a guide message for deleting the recorded title is displayed through the graphical user interface (GUI) (S210).

This allows the user to have a delay time to reconfirm the automatic deletion of the recording title by displaying a warning message to the user through a scenario provided by the user interface (UI) before deleting the recording title recorded on the HDD. This is to prevent the deletion.

Therefore, when the user views the guidance message provided through the user interface (UI) and selects "No", the recording operation is terminated. If the user command is not input even after a certain delay time, the user deletes the recording title and sets the scheduled recording. Since the user wants to record a content or there is no user, the microcomputer 70 deletes only one oldest title that can be deleted from the recording titles already recorded on the HDD in order to perform an optimal recording operation in any state. (S220).

After deleting one recording title already recorded on the HDD, it is determined whether the HDD can be recorded on the HDD by comparing the recording capacity of the HDD with the estimated recording capacity of the above-predicted contents (S230). The operation below S210 is repeatedly performed while deleting the recorded titles, which are fed back to S210 and already recorded on the HDD, one by one in the same manner.

When the recording is possible in the HDD according to the above operation, it is fed back to the S140 to perform the recording operation on the HDD and repeats the following operations.

The steps for copying the data temporarily stored in the HDD to the DVD after all the contents set by the reserved recording in the HDD are recorded in this manner and the system is terminated will be described with reference to FIG. 4.

4 is an operation flowchart of a data copying step of the digital recording apparatus according to the present invention.

First, when the user powers on the digital recording device (S300), the microcomputer 70 displays a guide message to copy the data temporarily stored in the HDD to the DVD (S310).

This allows the user to have a delay to reconfirm the management of the content by displaying a message to the user through a scenario provided by the user interface (UI) for storing the content temporarily stored on the HDD on a DVD desired by the user. For sake.

Therefore, when the user views the guidance message provided through the user interface (UI) and selects a copy operation (S320), after the DVD tray is opened and the user inserts the DVD (S330), the temporary data stored on the HDD is copied to the DVD. A recording operation is performed (S340).

As described above, according to the step-by-step recording apparatus and method of the digital recording apparatus according to the present invention, recording on a digital storage medium in recording content set by the reservation recording in a digital recording apparatus such as a DVD recorder including an HDD Even if it is impossible to record the desired content according to the step-by-step recording scenario, and through the step-by-step scenario provided through the user interface, the user can easily and safely select the desired step-by-step recording operation.

In addition, the present invention can safely record the content selected by the user through the efficient management of the title recorded on the digital storage medium even when there is no user.

In addition, the present invention can safely record content using a HDD as a large buffer when recording is not possible due to insufficient recording capacity of a digital storage medium such as a DVD, and recording while content is recorded on a large storage medium such as a HDD. If the capacity is insufficient, the title is automatically deleted, so that the selected content can be safely recorded in any situation where recording is difficult.

What has been described above is only one embodiment for implementing the step-by-step recording apparatus and method of the digital recording apparatus according to the present invention, the present invention is not limited to the above-described embodiment, it is within the technical spirit of the present invention Of course, various modifications are possible by one of ordinary skill in the art.
