Best Mode for Carrying Out the Invention Preferred embodiments of a recording control method in a composite recording apparatus according to the present invention will now be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration diagram of a composite recording apparatus to which the present invention is applied.

As shown in FIG. 1, the composite recording apparatus includes a key input unit 110, a microcomputer 120, a recording amount detector 130, a tuner 140, a reproduction and recording signal processor 150, and a display 160. ), A digital video disc (DVD) 170, and a hard disk device (HDD) 180.

The key input unit 110 includes a plurality of keys for setting a broadcast signal selection, recording and playback mode, and transmits the set key values to the microcomputer 120.

The microcomputer 120 controls the reproduction and recording operation of the broadcast signal input from the tuner 140 to be described later by the key value received from the key input unit 110, and the HDD 180 according to the recording amount of the DVD which is a recording medium. Control the temporary storage of

That is, the microcomputer 120 performs a recording mode to control recording of real-time broadcast information input through the tuner 140 and the playback and recording signal processing unit 150 to the DVD 170. When the recordable amount of the DVD 170 is less than a predetermined amount (10 minutes), the current recording information is temporarily stored in the HDD, and the information temporarily stored in the HDD 180 is recorded in the replaced DVD.

The playback and recording signal processing unit 150 processes the real-time broadcast information input through the tuner 140 under the control of the microcomputer 120, and in the playback mode, the broadcast-processed broadcast signal through the display 160. In the recording mode, the broadcast signal processed by the signal is output through the display 160 and simultaneously recorded on the DVD 170.

In addition, the playback and recording signal processing unit 150 stops the recording mode of the DVD 170 when the DVD replacement occurs in the real-time recording mode under the control of the microcomputer 120 and at the same time the broadcast information processed signal HDD (180) Make a temporary note on In addition, when the replacement of the DVD is completed by the control of the microcomputer 120, the reproduction and recording signal processing unit 150 stops the temporary recording operation on the HDD 180 and at the same time performs recording on the replaced DVD again.

In this case, the replaced DVD secures the recording space by the amount of the video information temporarily recorded on the HDD 180 and then records the broadcast signal in real time. Therefore, after the real-time recording and recording is finished, the playback and recording signal processing unit 150 inserts the video information temporarily recorded on the HDD 180 into the space secured in the replaced DVD under the control of the microcomputer 120. Signal processing.

As shown in FIG. 2, the terrestrial broadcast recording mode is set by the recording mode input through the external key input unit 110 (S20), and the broadcast signal input in real time through the tuner 140 is reproduced and After the processing through the recording signal processing unit 150, the output is output to the display 160 and recorded on the DVD 170 (S21 and S22).

At this time, the microcomputer 120 checks the remaining recording space of the DVD detected by the recording amount detector 130 (S23), and checks whether the remaining recording space is 10 minutes or more (S24).

As a result of the determination in step S24, when the remaining recording space of the DVD is confirmed to be 10 minutes or longer, the process returns to step S22 to continue recording on the DVD.

As a result of the determination in the step S24, when the remaining space of the DVD is not confirmed for 10 minutes or more, the microcomputer 120 temporarily records the same contents on the HDD 180 while continuing recording on the DVD 170 ( S25).

That is, as shown in FIG. 3, when the remaining recording space of the DVD (DVD A) on which the current real-time broadcast information is recorded reaches 10 minutes, which is To in time, the microcomputer 120 at the time T1 at this time is the HDD 180. Simultaneously record real-time broadcast information and output text information indicating replacement of the DVD via the display 160, for example, "The current DVD is out of space. Please replace it with another DVD." The voice message is output to the outside through S26.

At this time, it is determined whether the replacement of the DVD is confirmed by an externally output text or voice message (S27). If the replacement of the DVD is not confirmed in the process (S27), the process returns to the process (S25) and the HDD 180 Repeats the loop.

On the other hand, if it is determined in step S27 that the replacement with a new DVD is confirmed, that is, the DVD having insufficient recording space stops the recording operation at T2 time and the new DVD (DVD B) is replaced to record at T3 time. When the standby state for the microcomputer 120 stops the temporary recording operation of the HDD 180, and checks the amount of time (Ta) temporarily recorded when replacing the DVD to the current HDD 180 (S28).

Thereafter, the microcomputer 120 secures the amount of space temporarily recorded on the current HDD in the replaced DVD, and continuously records the image information signaled by the playback and recording signal processor 150 to complete recording. (S29.S30).

Therefore, the amount Ta temporarily recorded on the HDD in the space reserved for the replaced DVD after the recording is finished is recorded as the DVD B replaced by the playback and recording signal processing unit 150 under the control of the microcomputer 120. (S31).

Here, in the present invention, the recording amount stored temporarily in the HDD is inserted into the replaced DVD after the recording is finished, but due to the characteristics of the nonlinear recording and playback, the playback order is specified, in order of DVD before replacement, HDD and DVD after replacement. You can also play.
