CROSS-REFERENCE TO RELATED APPLICATIONS  
       [0001]     This application claims the benefit under 35 U.S.C. § 119(a) from Korean Patent Application No. 2004-52330, filed on Jul. 6, 2004 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.  
       BACKGROUND OF THE INVENTION  
       [0002]     1. Field of the Invention  
         [0003]     The present invention relates to an optical recording and reproducing apparatus for making one title automatically after a relay recording employed when capacity of an optical disc is insufficient when an image source is recorded onto the optical disc because of capability of the relay recording in copying one predetermined title, which is created automatically onto a recording medium such as a hard disc drive (HDD), onto one or more optical discs and a method thereof.  
         [0004]     2. Description of the Related Art  
         [0005]     As broadcasting signals have been digitalized and compression technology has advanced, optical recording and reproducing apparatus capable of recording broadcasting signals onto a recording medium and reproducing the recorded broadcasting signals has progressed with expanded functions. Especially, the development of optical recording and reproducing apparatuses has focused on being compatible with various image sources such as satellite broadcasting signals, cable broadcasting, network broadcasting through the use of the Internet and so forth. Also, the digitalization of data and advancement in compression technology has led to the developmental stage of recording data onto an optical media medium such as a compact disc-read only memory (CD-ROM) title or a digital versatile disc (DVD) title, or reproducing the recorded data. This type of optical medium barely degrades image quality over the course of long usage periods. Also, since the optical medium is capable of storing high-quality images and audio data of multi-channels, for instance, 5.1 channels, the optical medium has rapidly replaced conventional analog image recording media.  
         [0006]     Furthermore, optical medium, for instance, the DVD title for storing image data and audio data, is capable of storing data typically from several hundred megabytes to several gigabytes. In particular, a recently developed optical recording and reproducing apparatus adopts a HDD, which is a memory device with a high capacity for storing enormous amounts of data and that is easily read.  
         [0007]     A DVD/HDD optical recording and reproducing apparatus is one representative example. The DVD/HDD optical recording and reproducing apparatus is configured such that a DVD drive for recording data and reproducing the recorded data and a HDD for recording data are combined together within one case. Generally, the DVD drive reproduces individual data recorded onto an optical disc recording medium such as a DVD, an audio CD, a video CD, a MP3 CD or the like.  
         [0008]     In the case that the HDD is subjected to a relay recording because of insufficient disc capacity when a user records received signals from an external source by using an optical disc of the DVD drive, two titles are separately recorded onto corresponding recording media. That is, one title is recorded onto the optical disc and the other title is recorded onto the HDD.  
         [0009]     However, to watch a program split with two titles, there may be inconvenience requiring two recording media, that is, the optical disc and the HDD.  
       SUMMARY OF THE INVENTION  
       [0010]     Additional aspects and/or advantages of the invention will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the invention.  
         [0011]     It is, therefore, an object of the present invention to provide an optical recording and reproducing apparatus for making one title automatically after relay recording is employed when capacity of an optical disc is insufficient when an image source is recorded onto the optical disc because the relay recording enables creation of one predetermined title onto a recording medium such as a hard disc drive (HDD) and a method thereof.  
         [0012]     In accordance with one aspect of the present invention, there is provided an optical recording and reproducing method for an optical recording and reproducing apparatus, including performing a relay recording such that some of audio visual (AV) signals that are not recorded onto an optical disc are recorded onto a recording medium in case of insufficient optical disc capacity when the AV signals in a stream type from an image source are recorded onto the optical disc; and combining some of the AV signals recorded onto the recording medium with the rest of the AV signals recorded onto the optical disc when the relay recording is terminated, and storing the combined AV signals as one title onto the recording medium.  
         [0013]     The optical recording and reproducing method further includes requesting a selection of whether to record the one title onto a new optical disc; and recording the one title onto the new optical disc when recording of the one title onto the new optical disc is selected.  
         [0014]     The request of selecting whether to record the one title onto the new optical disc may proceed by displaying a corresponding message.  
         [0015]     Particularly, recording the one title onto the new optical disc includes requesting to set the number of new optical discs to be copied and setting the intended number of the new optical discs to be copied; requesting to install a new optical disc onto an optical disc drive, detecting the installation of the new optical disc, and recording the one title onto the new optical disc; and recording the one title repeatedly onto each of the different optical discs until the number of recorded new optical discs is identical to the set number of the new optical discs.  
         [0016]     Requesting to set the number of the new optical discs to be copied and the step of requesting to install the new optical disc onto the optical disc drive may be executed by displaying corresponding messages.  
         [0017]     The aforementioned recording medium may be a hard disc drive.  
         [0018]     The optical disc and the new optical disc may be compact discs (CDs) or digital versatile discs (DVDs).  
         [0019]     In accordance with another aspect of the present invention, there is provided an optical recording and reproducing apparatus, including an optical disc drive for recording audio video (AV) signals in a stream type from an image source onto an optical disc and reading the recorded AV signals; a recording medium onto which the AV signals in the stream type are recorded; and a control unit for controlling the optical disc drive and the recording medium to store the AV signals as one title onto the recording medium through detecting insufficient optical disc capacity during the recording of the AV signals onto the optical disc, performing a relay recording of the AV signals that are not recorded onto the optical disc to the recording medium, and combining the some of the AV signals recorded onto the recording medium with the rest of the AV signals recorded onto the optical disc when the relay recording is terminated.  
         [0020]     Also, the optical recording and reproducing apparatus further includes a key input unit. After the recording of the AV signals as the one title, the control unit controls the optical disc drive such that the one title is recorded onto a new optical disc when a recording selection signal is input to the new optical disc through the key input unit.  
         [0021]     Preferably, the optical recording and reproducing apparatus includes a display unit. After the recording of the AV signals as the one title, the control unit controls the display unit to display a message requesting whether to select the recording of the one title onto the new optical disc.  
         [0022]     Furthermore, the control unit may control the optical disc drive to record the one title onto each of the different new optical discs in a repetitive manner by detecting installation of the new optical disc when the number of signals corresponding to the intended number of optical discs to be copied and a signal for selecting recording of the one title onto the new optical disc are input through the key input unit, recording the one title onto the installed new optical disc, determining whether the number of recorded optical discs is identical to the intended number of new optical discs to be copied, and repeating the recording of the one title onto each of the different new optical discs until the number of the recorded optical discs becomes identical to the intended number of new optical discs.  
         [0023]     As mentioned above, the optical recording and reproducing apparatus further includes display unit. The control unit controls the display unit to display a message requesting an input of the number of new optical discs to be copied and another message requesting installation of the new optical disc.  
         [0024]     The recording medium may be a hard disc drive.  
         [0025]     Additionally, the optical disc and the new optical disc may be DVDs or CDs.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0029]     Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below to explain the present invention by referring to the figures.  
         [0030]      FIG. 1  is a block diagram showing an optical recording and reproducing apparatus for making one title automatically after a relay recording in accordance with an embodiment of the present invention.  
         [0031]     With reference to  FIG. 1 , the optical recording and reproducing apparatus includes an. input and output terminal unit  100 , a tuner  110 , a switching unit  120 , a moving picture experts group (MPEG) encoding unit  130 , a user interface unit  140 , an optical disc drive  150 , a hard disc drive (HDD)  160 , and a control unit  170 .  
         [0032]     The input and output terminal unit  100  inputs signals generated from various image signal sources and outputs signals reproduced from the optical disc drive  150  and the HDD  160 .  
         [0033]     The input and output terminal unit  100  includes a radio frequency input terminal (RF IN)  101 , a RF output terminal (RF OUT)  103 , a line video and audio input terminal (LINE V_IN and LINE A_IN)  105 , and a video and audio output terminal (LINE V_OUT and LINE A_OUT)  107 .  
         [0034]     Herein, one of the above input terminals and output terminals having the same signal types except for input and output relationships will be described in detail. The RF input terminal  101  is a terminal for receiving sky wave broadcasting signals and is typically connected to an antenna.  
         [0035]     The line video and audio input terminal  105  is a terminal for receiving analog signals mixed with a brightness signal Y and color signals, and is connected to a camcorder, set-top-boxes or the like supporting outputs of analog signals.  
         [0036]     The tuner  110  adjusts a receiver channel to allow broadcasting signals from a channel specifically requested by an input and output control unit (not shown) to be received through the RF input terminal  101 .  
         [0037]     The switching unit  120  is controlled by the input and output control unit (not shown) and, especially controls those input and output terminals of the input and output terminal unit  100  connected to the switching unit  120  to be connected selectively with each other.  
         [0038]     The MPEG encoding block  130  includes a video decoder  133 , an audio analog-to-digital (A/D) conversion unit  136 , and an MPEG encoder  139 .  
         [0039]     The video decoder  133  decodes signals input through the switching unit  120  and outputs decoded signals. The audio A/D conversion unit  136  converts analog audio signals input through the switching unit  120  into digital signals and outputs the converted signals to the MPEG encoder  139 .  
         [0040]     The MPEG encoder  139  is controlled by the control unit  170 , and compresses the audio signals output from the audio A/D conversion unit  136  and the video signals output from the video decoder  133  into a predetermined compression format type, thus generating audio visual (AV) signals in a stream type.  
         [0041]     The user interface block  140  includes a key input unit  143  and a display unit  146 .  
         [0042]     The key input unit  143  allows a user to input a manipulation command signal, a selection signal for recording one title of the HDD  160  onto a new optical disc, and signals corresponding to the number of new optical discs that a user intends to copy.  
         [0043]     The display unit  146  displays a message asking the user whether to copy one title of the HDD  160  onto a new optical disc, for instance, “Do you want to copy this title onto a new optical disc?” Another message asks the number of new optical discs to be copied, for instance, “Please enter the number of optical discs to be copied.” Another message asks the user to install a new optical disc, for instance, “Please install an optical disc.” 
         [0044]     The optical disc drive  150  records the AV signals in the stream type generated by the MPEG encoder  139  onto an optical disc  150   a , or reads the AV signals recorded onto the optical disc  150   a . The optical disc  150   a  can be a digital versatile disc (DVD) or a compact disc (CD).  
         [0045]     The AV signals in the stream type generated by the MPEG encoder  139  are recorded onto the HDD  160 .  
         [0046]     The control unit  170  detects whether the capacity of the optical disc  150   a  runs out in the course of the AV signals in the stream type generated by the MPEG encoder  139  are recorded onto the optical disc  150   a.    
         [0047]     If the optical disc capacity runs out, the AV signals are subjected to a relay recording applied onto the HDD  160 . After the relay recording is terminated, the control unit  170  controls the optical disc drive  150  to read some of the AV signals recorded onto the optical disc  150   a . Subsequently, through another control by the control unit  170 , the read AV signals recorded onto the optical disc  150   a  are combined with some of the AV signals recorded onto the HDD  160 , and these combined AV signals are stored as one title onto the HDD  160  thereafter.  
         [0048]     The control unit  170  controls the display unit  146  to display a message whether to copy the one title of the HDD  160  onto a new optical disc after the control unit  170  stores the one title onto the HDD  160 .  
         [0049]     If a recording selection signal is input to the new optical disc through the key input unit  143 , the control unit  170  controls the display unit  146  to display a message asking a user about the number of new optical discs to be copied.  
         [0050]     When signals having the corresponding number to that of the new optical discs to be copied are input through the key input unit  143 , the display unit  170  controls the display unit  146  to display a message asking a user to install a new optical disc.  
         [0051]     The control unit  170  detects the installation of the new optical disc, and when the installation of the new optical disc is detected, the control unit  170  makes the optical disc drive  150  dub the one title of the HDD  160  onto the installed new optical disc. Afterwards, the control unit  170  determines whether the number of the recorded new optical discs is identical to the intended number of the new optical discs to be copied.  
         [0052]     If the same number of the new optical discs is recorded, the control unit  170  terminates the recording of the one title onto the new optical disc.  
         [0053]      FIG. 2  is a flowchart describing an optical recording and reproducing method for making one title automatically after a relay recording in accordance with an embodiment of the present invention. With reference to  FIGS. 1 and 2 , at operation S 200 , AV signals in a stream type from an image source including broadcasting signals are recorded onto the optical disc  150   a  by the optical disc drive  150 .  
         [0054]     At operation S 210 , the control unit  170  detects whether capacity of the optical disc  150   a  runs out in the course of recording the AV signals onto the optical disc  150   a.    
         [0055]     At operation S 220 , if the capacity of the optical disc  150   a  runs out, the rest of the AV signals that are not recorded onto the optical disc  150   a  are subjected to a relay recording onto the HDD  160 .  
         [0056]     Conversely, if the capacity of the optical disc  150   a  does not run out during the recording of the AV signals, the executed recording is terminated.  
         [0057]     When the relay recording with respect to the HDD  160  is terminated, at operation S 230 , through control by the control unit  170 , some of the AV signals recorded onto the optical disc  150   a  by the optical disc drive  150  are read, and the read AV signals are combined with the rest of the AV signals recorded onto the HDD  160  so that one title is created onto the HDD  160 .  
         [0058]     Afterwards, a message asking whether or not the one title of the HDD  160  should be dubbed onto a new optical disc is displayed on the display unit  146 , and at operation S 240 , the key input unit  143  is used to select whether to dub the one title of the HDD  160  onto the new optical disc.  
         [0059]     If the dubbing of the one title of the HDD  160  is selected, at operation S 250 , the display unit  146  displays a message asking a user about the number of new optical discs to be copied, and the intended number of new optical discs to be copied is selected through the key input unit  143 .  
         [0060]     The display unit  146  displays a message to install the new optical disc, and at operation S 260 , the control unit  170  detects whether the new optical disc is installed on the optical disc drive  150 .  
         [0061]     Once the new optical disc installation is detected, at operation S 270 , the optical disc drive  150  records the one title of the HDD  160  onto the new optical disc.  
         [0062]     At operation S 280 , the control unit  170  detects whether the number of the recorded new optical discs is identical to the intended number of the new optical discs to be copied.  
         [0063]     If these two numbers are the same, the relay recording is terminated.  
         [0064]     Conversely, if the number of the recorded new optical discs is not same as the intended number of the new optical discs to be copied, at operation S 260 , the display unit  146  displays a message requesting installation of a new optical disc.  
         [0065]     The above operations are repeated until the number of the recorded new optical discs is identical to the intended number of the new optical discs to be copied.  
         [0066]     In accordance with an embodiment of the present invention, as a relay recording is conducted because of insufficient optical disc capacity when AV signals from an image source are recorded onto an optical disc, AV signals recorded onto each of the optical disc and a HDD are stored as one title automatically, which is, in turn, dubbed onto one or more optical discs. As a result, a user can watch the recorded image through one recording medium selected between either the HDD and the optical disc. Also, it is possible to collect a plurality of copied optical discs.  
         [0067]     The foregoing embodiment and advantages are merely exemplary and are not to be construed as limiting the present invention. The present teaching can be readily applied to other types of apparatuses. Also, the description of the embodiments of the present invention is intended to be illustrative, and not to limit the scope of the claims, and many alternatives, modifications, and variations will be apparent to those skilled in the art.
