Referring to FIG. 1, a key input block 102 is a user operation for controlling a recording and playback operation of an optical disc recording apparatus in response to a key input by a user using input means (for example, a remote controller, etc.) not shown. By generating a signal (for example, an optical disc recording operation signal, an optical disc reproduction operation signal, etc.), various operation signals generated here are transmitted to the control block 104.

In addition, the control block 104 performs overall control of the optical disk recording apparatus, including, for example, a microprocessor, for tuning the selected broadcast channel according to an operation signal provided from the key input block 102. The control signal is provided to the tuner and demodulation block 106.

In addition, the control block 104 provides a control signal to the MPEG block 108 for decoding the transmitted broadcast data and then compressing the received broadcast data to the MPEG method (for example, the MPEG2 method), which is provided from the MPEG block 108. The signal processing block 114 provides a control signal for signal processing of the broadcast data for reproduction through a monitor and speaker (not shown). At this time, the control block 104 stores the additional information (for example, program guide information (EPG), etc.) of the broadcast data transmitted from the MPEG block 108 in the storage medium 112.

In the control block 104, a control signal for recording compressed broadcast data on an optical disc (for example, a DVD) or extracting the recorded broadcast data is provided to the optical disc loading block 110, and the respective optical disc information is provided. The control signal for detecting the signal is provided to the optical disc loading block 110.

In addition, the control block 104 detects the program information and the pre-recorded broadcast data information of the broadcast data to be recorded from the storage medium 112 according to the recording operation signal from the key input block 102, and compares them. It is checked whether the same program exists, and if the same program exists, the corresponding disk information (for example, optical disc number, recorded program name, etc.) is extracted, and the corresponding optical disc on which the same program is recorded is stored in the optical disc loading block 110. Checks if it is picked up and installed, and if it is currently installed, detects and compares the amount of broadcast program data to be recorded with the remaining information of the corresponding optical disk, and if it is possible to record, the control signal for recording the broadcast program to be recorded on the corresponding optical disk. To the MPEG block 108 and the optical disc loading block 110. . Here, the program information may include, for example, a program name, a broadcast time, a program data amount, and the like, and the broadcast data information may include, for example, a program name, a broadcast time, a program name, a recording time, an optical disc number, and the like. The remaining information of the optical disc may include, for example, an optical disc number, total recording capacity, used capacity, remaining capacity, and the like.

On the other hand, in the control block 104, if the same program does not exist from the program information of the broadcast data and the pre-recorded broadcast data information, the remaining amount information of the currently mounted optical disc is extracted, and the data amount of the broadcast program to record the same. When comparison is possible, the control signal for recording the broadcast program is provided to the MPEG block 108 and the optical disc loading block 110 when the comparison is possible.

In addition, the control block 104 can record after extracting the remaining amount information for each optical disc of the disc changer from the optical disc loading block 110 when recording is not possible according to the data amount of the broadcast program to be recorded and the remaining amount information of the corresponding optical disc. If there is an optical disc, a control signal for replacing the optical disc and a control signal for recording a broadcast program on the replaced optical disc are provided to the optical disc loading block 110.

Next, the tuner and demodulation block 104 receives a broadcast signal received through an antenna or a broadcast signal transmitted by wire, and selects a corresponding channel from the received broadcast signal according to a control signal input from the control block 102. After tuning, the broadcast data of the tuned channel is demodulated and delivered to the MPEG block 106.

The MPEG block 108 variable lengths the compressed and encoded broadcast signal (broadcast program signal) of a specific channel with respect to the broadcast data provided from the tuner and the demodulation block 106 according to the control signal provided from the control block 104. Decoded, inverse DCT, inverse quantization, and motion compensation are used to perform a series of decoding to restore the original signal before encoding, and then compress and compress it by MPEG (eg MPEG2, MPEG4, etc.). The broadcast data may be delivered to the optical disc loading block 110 or the broadcast data recorded on the optical disc may be received from the optical disc loading block 110 and decompressed by MPEG or the like to be transmitted to the signal processing block 114. At this time, the MPEG block 108 extracts additional information (eg, program guide information (EPG), etc.) for the broadcast data and transmits the additional information to the control block 104.

In addition, the optical disc loading block 110 includes a general DVD RW function for recording or playing back broadcast data using an optical disc (for example, DVD) mounted on a disc changer or the like. Broadcast data transmitted from the MPEG block 108 is recorded on the optical disc in accordance with the control signal provided from 104.

The optical disc loading block 110 extracts the disc information or the remaining amount of optical disc information of the optical discs mounted on the disc changer according to the control signal from the control block 104 and provides the same to the control block 104, and the control block 104. The compressed broadcast data delivered from the MPEG block 108 is optically picked up and mounted on the disc changer and recorded on the corresponding optical disc.

Next, the storage medium 112 includes a general storage medium (i.e., a memory, etc.) of the optical disc recording apparatus, and stores various application programs for the operation of the optical disc recording apparatus. For example, broadcast program guide information, etc.) are stored, and previously recorded broadcast data information is stored.

Meanwhile, the signal processing block 114 processes video and audio signals from the MPEG block 108 and reproduces them through a monitor and a speaker (not shown). Here, in the signal processing block 114, various menu screens may be mixed with the video signal according to the control signal from the control block 104 and then displayed on a monitor not shown.

Next, in the optical disk recording apparatus having the above-described configuration, if there is a recording operation signal, program information of broadcast data to be recorded is detected, and the program information is compared with the previously recorded broadcast data information. The process of extracting optical disc information, selecting and replacing the corresponding optical disc according to the extracted optical disc information, and then selecting and replacing the corresponding optical disc according to the remaining optical disc information will be described.

Here, the program information may include, for example, a program name, a broadcast time, a program data amount, and the like.

The control block 104 extracts previously recorded broadcast data information from the storage medium 112, and compares it with the program information of the detected broadcast data (step 208). In this case, the broadcast data information may include, for example, a program name, a broadcast time, a program name, a recording time, an optical disc number, and the like.

Next, the control block 104 checks whether or not the same program as the one to be recorded is already recorded according to the comparison result in step 208 (step 210).

As a result of the check in the step 210, if the same program is pre-recorded, the control block 104 extracts information about the optical disc on which the program is recorded (step 212). Here, the optical disc information can be extracted from the broadcast data information using an optical disc number, a recorded program name, and the like.

Then, the control block 104 extracts the information (for example, the optical disc number, the recorded program name, and the like) for each optical disc mounted in the disc changer from the optical disc loading block 110, and the same program is recorded. It is checked whether the optical disc is currently picked up and mounted (step 214).

As a result of the check in the step 214, if the corresponding optical disc on which the same program is recorded is not currently optically picked up and mounted, the optical disk is picked up and replaced by the optical disk via a disk changer and replaced (step 216).

On the other hand, when the result of the check in step 210 does not record the same program or the result of the check in step 214, the corresponding optical disc on which the same program is recorded is currently optically picked up and mounted. In block 104, the remaining amount information of the optical disc is extracted from the optical disc loading block 110 and compared with the amount of program data from the program information to be recorded (step 218). Here, the remaining amount of optical disc information may include, for example, an optical disc number, total recording capacity, used capacity, remaining capacity, and the like.

Then, the control block 104 checks whether or not recording of the broadcast program to be recorded on the corresponding optical disc is possible according to the comparison result in step 218 (step 220).

As a result of the check in the step 220, when the recording of the broadcast program to be recorded on the optical disk is possible, the control block 104 provides a recording control signal, accordingly the MPEG block 108 and the optical disk loading block 110 Record the broadcast program through (step 222).

As a result of the check in the step 220, if it is impossible to record a broadcast program to be recorded on the optical disk, the control block 104 extracts the remaining information of the remaining optical disk mounted on the disk changer from the optical disk loading block 110. In accordance with the remaining information, a control signal for replacing with another recordable optical disc is provided to the optical disc loading block 110, and the optical disc loading block 110 replaces with another optical disc recordable using a disc changer, and the MPEG block 108 In step 224, the broadcast program transferred from the &lt; RTI ID = 0.0 &gt;

In this case, the control block 104 provides a control signal for generating and displaying a menu screen informing that there is no recordable optical disk according to the extracted optical disk remaining information, and accordingly the signal processing block 114 The generated menu screen may be mixed with a video signal and displayed on a monitor not shown. In addition, when the recording of the broadcast data ends, the control block 104 may update the broadcast data information and the optical disc information and store the information in the storage medium 112 and the storage medium 112.

On the other hand, the present invention described above is described as recording by using a disk changer in accordance with the user's recording operation, the recording of the broadcast data using the disk changer can also be performed during the scheduled recording of the optical disk recording apparatus, of course. to be.

Therefore, when recording the broadcast data in the optical disc recording device, it is checked whether the same program is recorded according to the program information and the pre-recorded broadcast data information, and then it is selected and replaced with the corresponding optical disc in which the same program is recorded and selected according to the remaining amount of optical disc information. The broadcast data can be recorded.
