TECHNICAL FIELD The present invention relates to recording and reproducing technology of a digital recording / reproducing system, and more particularly, to an apparatus and method for processing title additional information in a digital recording / reproducing system suitable for facilitating retrieval and management of stored titles.

In the A / V device using a conventional analog system, there is no control method and means for controlling the interaction between the A / V device and other A / V devices connected and connected to each other. In order to control, a user has to input separate operation control keys to the A / V device, respectively.

However, A / V devices using current digital methods, such as compact disc (CD) or mini disc (MD) players, which are digital audio data recording media, use the IEEE 1394 interface, which is a digital communication interface. By connecting to another A / V device, the digital data transmission and operation control between the A / V devices is performed by using a command set defined in advance.

In general, an optical disc, which is a large-capacity recording medium capable of recording and storing digital data such as audio or video tape, is a recording disc for reproduction only, such as CD-ROM and DVD-ROM, and one-time recording such as CD-R and DVD-R. There are optical discs capable of this, and rewritable optical discs such as CD-RW, DVD-RAM, and DVD-RW.

In recent years, DVD (Digital Versatile Disc), which is a large-capacity, high-density optical disc capable of recording and storing high-quality video data or high-quality audio data for a long time, has been widely used, and such DVDs use the MPEG (Moving Picture Experts Group) codec. It may be connected to a display device such as a digital TV through a digital communication interface. In the case of a DVD player, such an MPEG codec is provided within the DVD player, so that various ports can be easily connected, and the user can efficiently edit and produce still images and movies by using the MPEG codec.

On the other hand, the DVD title can record a plurality of sub-titles from the large capacity feature of the DVD, and the DVD title reproducing apparatus supports to selectively display a plurality of sub-titles recorded in the DVD title. The DVR also supports the ability to copy desired sub-titles together when recording DVD titles onto DVD discs.

In particular, as the prevalence of DVRs that can record information on DVD discs increases, the production and editing of DVD discs in addition to the sub-title information input function is expected to be easily implemented in general homes.

However, in the case of later checking the information recorded by such a DVD title, even if the title information is huge, even if the sub-title information can be confirmed, it is often difficult to remember the specific contents or memories related to the title. .

That is, there is a problem that it is not possible to know exactly when, where, and under what circumstances the title was taken by sub-title information alone. In addition, since the user has no choice but to "play back" the titles in order to restore the memories of the specific information related to the titles, the user has to check a large amount of titles one by one.

Therefore, the user can use the detailed information related to the title (recording history information of the title to which the user can distinguish / recognize each title) without reproducing a plurality of titles recorded on the storage medium (hard disk or DVD) of the DVD player. There is a need for technical measures that can be perceived.

In addition, the MPEG unit 104 performs MPEG decoding processing of the background image files (MPEG, JPEG) / background music files (MP3) and provides them to the video output unit 106 or the audio output unit 108.

Also, the MPEG unit 104 converts a voice signal provided from the voice recognition processor 122 to be described later into a digital signal and provides the converted signal to the loading unit 114 or the storage medium 116. In other words, the present embodiment adds an external user voice to a DVD title, and adds user voice information to the DVD title recorded on the storage medium 116 or DVD via the MPEG unit 104.

The video output unit 106 converts the video signal provided from the MPEG unit 104 into R, G, and B signals, converts the video signal into a composite video signal, and outputs the result to the TV screen. The audio signal processing unit 108 converts the MPEG unit 104 into a TV screen. The audio signal provided from) is converted into an analog signal and output to the outside through a TV speaker.

The key input unit 110 is a key input unit provided on the front panel of the DVD player or the upper surface of the remote controller. The key input unit 110 generates a key signal corresponding to a key button input action of the user and provides the same to the controller 112. In particular, the key input unit 110 may apply the additional information input key signal for inputting additional information to the DVD title to the controller 112.

The control unit 112 responds to the title additional information input key signal from the key input unit 110 as described above with the video / audio signal processing unit 102, the MPEG unit 104 and the voice recognition processing unit 122 described later. By controlling the overall operation of the recording medium 116 or DVD, predetermined language-processed DVD title information is recorded.

The loading unit 114 may be configured as an optical pickup unit, a servo unit, and the like, which are not shown, and under the control of the control unit 112, a DVD player may perform playback and recording related operations to externally store video and audio information recorded on a DVD. It plays the role of outputting to the DVD or recording additional information such as external shooting information or user's voice.

The storage medium 116 is, for example, a hard disk drive (HDD), which stores image information recorded from an external device (digital camera, camcorder, etc.), that is, playable multimedia files (background file, background music file, etc.) The files stored by the control unit 112 are output. In addition, in addition to title information such as a background image and background music, the storage medium 116 records basic information and main information for distinguishing titles as voice information of the user.

That is, in the present embodiment, the title information, the background information, the background music information, the user voice information (consisting of basic information and main information), and the like are recorded on the DVD or the storage medium 116. It may be chosen arbitrarily according to the selection.

The memory unit 118 may be configured of, for example, a RAM, and stores various kinds of information necessary for driving the DVD player.

The voice recognition processor 122 according to the present embodiment extracts a voice signal of a person input through the microphone 120 and provides the extracted voice signal to the MPEG unit 104.

Hereinafter, with reference to the above-described configuration, with reference to the flowchart of Figs. 2 and 3 attached to the title additional information processing process in the digital recording / playback system according to a preferred embodiment of the present invention will be described in detail.

First, FIG. 2 shows a process of inputting title additional information in a digital recording / reproducing system.

As shown in FIG. 2, in step S200, the controller 112 determines whether an arbitrary title is selected from the key input unit 110. This arbitrary title selection may be a title recorded on the DVD or may be a title recorded on the storage medium 116.

As a result of the determination in step S200, if an arbitrary title is selected, the controller 112 proceeds to step S202 to display the additional information input menu screen.

If the voice input is selected by the key input unit 110 in the additional information input menu screen, the control unit 112 proceeds to step S206 to control the microphone 120, the voice recognition processing unit 122, and the like, and the voice recognition function. Activate and proceed to step S208.

In step S208, the controller 112 proceeds to the basic voice information input mode. The basic voice information input mode refers to a user interface environment for inputting only the minimum voice information that allows the user to check what title the title is in the voice information input by the user. For example, a user interface environment is created so that only basic audio information such as recording date and recording location can be input.

After performing step S208, in step S210, the controller 112 determines whether basic information input is completed through the key input unit 110, and when the basic information input is completed, the controller 112 performs step S212. Proceed to

In step S212, the controller 112 temporarily stores the basic voice information, that is, user voice information, input through the key input unit 110 in the memory unit 118, and proceeds to the main voice information input mode. The main voice information input mode refers to a user interface environment for inputting message information related to a corresponding title from voice information input by a user. For example, a user interface environment is created so that descriptions related to titles and user nurturing desired to be entered can be input.

After performing step S212, in step S214, the controller 112 determines whether the main voice information input is completed through the key input unit 110, and when the main voice information input is completed, the controller 112 performs the step ( Proceed to S216).

In step S216, the controller 112 temporarily stores the main voice information, that is, user voice information, input through the key input unit 110 in the memory unit 118, and proceeds with the background / background music input mode. The wallpaper / background music input mode is a process in which a user can select a wallpaper file or a background music file stored in the storage medium 116.

When such a background / background music input is completed (S218), the control unit 112 proceeds to step S220 and the basic voice information, the main voice information of the user voice temporarily stored in the memory unit 118, and the background / Background music information is added to the title and set as the final title information (e.g., Title A). The finally set title information may be performed on a storage medium 116 or a DVD on which the title is recorded, and may be transmitted by e-mail to a third party through an external network, for example, the Internet.

Next, Fig. 3 shows a title additional information output and title reproduction process in the digital recording / reproducing system.

As shown in FIG. 3, in step S300, the controller 112 determines whether a random title is selected through the key input unit 110, and when the random title is selected, the controller 112 proceeds to step S302. Then, it is determined whether the selected title is a title, for example, Title A, to which additional information (information including at least one of basic information and voice information composed of main voice information and background / background music information) is inserted.

If it is determined in step S302 that no additional information is inserted into the selected title, the controller 112 proceeds to step S304 to perform a general title reproduction process.

If it is determined in step S302 that the title is a title into which additional information is inserted, that is, title A, the controller 112 proceeds to step S306 and step S308.

In step S306, the control unit 112 loads additional information of the selected title, that is, voice information consisting of basic voice information and main voice information, and background / background music information, and proceeds to step S308 in the voice information. The audio output unit 108 is controlled to output only the basic information message.

While the basic information message is outputted through the voice, the controller 112 proceeds to step S310 to determine whether the reproduction selection key is applied through the key input unit 110. That is, it is determined whether the user hears the basic voice information message of the title and decides to play the final voice.

If the playback selection key is not applied as a result of the determination in step S310, the controller 112 proceeds to step S312 and step S314 to provide the user with a skip menu screen for inducing another title selection and providing a title from the user. If skip is selected, the video output unit 106 is controlled to skip to the next title list of the title.

On the other hand, if the playback selection key is applied as a result of the determination in step S310, the control unit 112 proceeds to step S316 to determine whether the title is a photo title, and in the case of the photo title, the control unit 112 performs step ( In step S318, the video output unit 106 and the audio output unit 108 are controlled to output the main message from the voice information simultaneously with reproduction of the corresponding title.

However, if it is determined in step S316 that the title is not a photo title, for example, a video title, the controller 112 proceeds to step S320 and outputs a main voice information message from the voice information. Control 108.

When the output of the main voice information message is terminated (S322), the control unit 112 proceeds to step S324 to control the video output unit 106 to play the title.

That is, in the case of a video title, since the voice information of the corresponding title is often output together, in order to prevent duplication of the voice information as the additional information, the main voice information message, which is additional information, is output first, and then the additional information output is completed. Since the video title is played back, and in the case of a still image title such as a photograph, since the audio information does not exist (since there is no fear of duplicate output of the audio information), the main audio information is additional information in parallel with the playback of the still image title. It is implemented to print a message.

As described above, according to the present invention, information about a recorded title is additionally inserted as voice information, and when a playback request is subsequently made, the basic information of the title is briefly transmitted before the playback process. It is implemented to output background music and background screen simultaneously while outputting title main information among information.

The embodiments of the present invention have been described in detail above, but the present invention is not limited to these embodiments, and various modifications may be made by those skilled in the art within the spirit and scope of the present invention described in the claims below.

According to the present invention, the user can easily recognize the information on the title by additionally inserting the history information on the recorded title as the voice information, and briefly transmitting the title basic information of the relevant additional information before the playback process in the case of a playback request. In addition, since the user can output his or her own message information, additional background image, background music, etc., when the title is played, a more diverse and advanced user environment can be provided.
