The recording and reproducing apparatus 100 is a device capable of recording or reproducing optical discs of various standards. According to the design, only the optical disc of a specific standard can be recorded and reproduced. That is, the recording medium 300 may be a high density recording medium such as HD-DVD or BD.

In addition, the recording and reproducing apparatus 100 may be reproduced without recording, and the recording and reproducing apparatus 100 may be a drive that can be embedded in a computer or the like.

In addition to the function of recording and reproducing data on the recording medium 300, the recording and reproducing apparatus 100 according to an exemplary embodiment of the present invention receives a data signal from an external source 400 and processes the signal and then displays the external display apparatus 200. It has the function of passing it to the screen through the user. In this case, a data signal may be transmitted from an external source 400 through the Internet, and specific data on the Internet may be downloaded and utilized through the recording and reproducing apparatus 100.

On the other hand, with the development of high-density recording media, networking, communication technologies, and the like, it has become possible to provide data whose interactivity with the user significantly exceeds the existing recording media. However, in order to reproduce data providing high interactivity with a user, it is required that the recording / playback apparatus 100 be provided with a high speed processor, a large memory, and a complex program.

2 is a block diagram showing the overall configuration of the recording / playback apparatus 100 according to the embodiment of the present invention.

As shown in FIG. 2, the recording / playback apparatus 100 according to the embodiment of the present invention includes a pickup 12, a servo 14, a signal processor 16, a memory 18, a microcomputer 20, and a storage ( 22), the AV encoder 24, the AV decoder 26, the control unit 28 and the interactive module 30.

The pickup 12 irradiates light on the recording medium 300 to reproduce data from the recording medium 300 or to record data on the recording medium 300. It also plays a role in reproducing the recording medium 300 in which a title including interactive content and movie content is recorded. The servo 14 controls the operation of the pickup 12.

The signal processor 16 restores the reproduction signal received from the pickup 12 to a desired signal value, or modulates and transmits the signal to be recorded into a signal recorded on the recording medium 300.

The memory 18 stores various kinds of information necessary for data reproduction. In the present invention, the identification information of the recording medium, the mark information of the playlist, the reproduction position information of the movie content, and the like can be stored. The microcomputer 20 controls the operation of the pickup 12, the signal processor 16, the servo 14, and the memory 18.

The pickup / playback 12, servo 14, signal processor 16, memory 18, and microcomputer 20 may also be referred to as a recording / playback section. The recording / playback section may be configured as a single product.

In view of the reproduction, the recording / reproducing section reads the data from the recording medium 300, the memory 18, or the storage 22 under the control of the microcomputer and / or the control unit 28 and provides it to the AV decoder 26. In other words, the recording / playback section serves as a playback section for reading data from the viewpoint of playback.

In view of the recording, the recording / reproducing section is a recording section which receives the signal encoded by the AV encoder 24 and records the clip AV stream and management information about the clip AV stream on the recording medium 300.

The storage 22 is a kind of storage means provided in or connected to the recording / playback apparatus 100, and is an element that a user can arbitrarily store and utilize necessary information and data. Data with persistence may be stored in storage 22.

As the storage 22, a flash memory provided in the recording / playback apparatus 100 may be used. In addition, as the storage 22, a USB memory, an HDD memory, a memory card, or the like, which can be connected to the recording / playback apparatus 100 and can be used, can be used.

The storage 22 is also used as a means for storing data downloaded in association with the recording medium 300. Meanwhile, data read directly from the recording medium 300 may be stored in the storage 22.

The control unit 28 is responsible for controlling all the components in the recording / playback apparatus 100. In addition, the controller 28 may control the playback of the movie content to be paused and the execution of the application continues to be maintained at the time of the playback pause command. In addition, the control unit 28 determines the setting of an option regarding the complete reproduction of the interactive content or an option of whether to play the interactive content. In addition, when the power supply to the recording / playback apparatus 100 is released, the controller 28 stops the playback of the title and replays it later, and the like about the playback position of the corresponding movie content and the recording medium identification information. To store in the memory 18.

The control unit 28 and the microcomputer 20 may be provided separately to operate. In addition, the functions of the control unit 28 and the microcomputer 20 may be integrated to operate as one control unit. The controller may be composed of a program (software) and / or hardware provided in the recording / playback apparatus 100.

The AV decoder 26 finally decodes the output data under the control of the controller and provides the same to the user. The AV decoder 26 may include a plurality of decoders according to the type of data.

The AV encoder 24 converts the input signal into a signal of a specific format, for example, an MPEG-2 (MPEG2) transport stream, under the control of a control unit, in order to perform a function of recording a signal on an optical disc. ).

In addition, the memory 18 is a space for processing various information for reproducing the recording medium 300 and data related to the recording medium 300, iHD, navigation software, various buffers in the optical recording / reproducing apparatus, and operation. It is used as a space for an operation system.

In addition, the interactive module 30 is a space for processing various information related to the interactive application, and is configured by utilizing a memory 18 or a processor (not shown) provided or connected to the recording / playback apparatus 100. It is also possible that the interactive module 30 is configured as part of the control unit 28.

3 and 4 illustrate a conceptual understanding of title playback according to an embodiment of the present invention.

3 shows a relationship between title reproduction management information and expression objects constituting a title.

Meanwhile, in the present invention, a BD-J title which is a reproduction unit for reproducing data of a recording medium and / or local storage may be composed of an interactive object and an A / V expression object. However, in some cases, the title does not include the interactive object and may simply play back the A / V presentation object. For example, an autoplay playlist may run without an associated application. Similarly, a title does not necessarily need to contain a playback of an A / V presentation object. For example, a title may consist of only one or more applications, such as a game.

The title of the present invention may be composed of an interactive object and an A / V object. A / V objects can be represented as movie objects. Referring to FIG. 3, title 3 is divided into two chapters, and chapter 1 is represented by execution of a main audio / video object and a sub audio / video object and a sub title object and an interactive object.

In this regard, the main audio / video object is a representation object comprising one or more timemaps and a main audio stream and a main video stream used to convert the representation time of the representation object into the address of the representation unit in each representation object. In addition, the interactive object is an expression object including an interactive function to be implemented during the playback of the title.

The playback order of each chapter constituting Title 1, 2, 3 or 4 and the playback information between the respective expression objects are provided by the playlist. The playlist provides playback information between playback objects by mapping respective presentation objects onto a title timeline allocated for each title. The playlist may be recorded on a recording medium in the form of a playlist file or provided to a recording / playback apparatus from an external server.

Referring to FIG. 4, we can see the timeline provided by three playlists in Title 1. It is assumed that there are respective applications corresponding to the playlist. With the execution of the application, interactive content can be played back, and playback of the main audio / video stream or movie content and interactive content proceeds due to the play information of the playlist. If the video is to be stopped at a certain point in time during the playback of the title, the playlist may designate time information of any section of the playlist's time axis through mark information on the playlist.

However, an application that drives interactive content, specifically a Java application, cannot be resumed after execution stops at a certain time, and the application must be executed from the beginning when resuming playback after pausing or resuming playback. Thus, pausing and resuming playback of interactive content can be difficult due to the nature of the application.

Referring to FIG. 4, when there is a pause or playback stop command in a predetermined region of playlist 3 during playback of a title, playback position information of playlist 3 is stored, and playback of movie content and interactive content is stopped. Subsequently, when the playback of the title is resumed, it is executed again from the time when the first application 3 is driven, and accordingly, both the movie content and the interactive content are played back from the time when the first application 3 is driven. On the other hand, the user can select whether or not to completely reproduce the interactive content driven by the execution of the application. If you want to play a complete title that includes interactive content, you can play from the first playback position of the application because of the characteristics of the application, and the movie content is also played from the first playback position of the application according to the location information of the corresponding playlist. .

However, if the user wants to play only the movie content from the last end point instead of playing the complete title, the execution of the application can be stopped, that is, the movie content can be played without giving up the interactive content.

5, 6A, and 6B illustrate an image displayed on a screen according to an embodiment of the present invention.

In relation to the execution of the application, the playlist file information existing on the recording medium or the local storage is interpreted to execute the playlist. Clips played by the execution of the playlist are decoded according to the type of stream through the decoder and displayed to the user through planes.

In relation to this, in the present invention, the plane refers to a conceptual model for explaining an overlay process of the expression objects displayed on the screen. The plane model makes it possible to independently control main video objects, subtitles, and interactive objects.

Referring to FIG. 5, the main audio / video stream is displayed in the main video plane, the sub title stream is displayed in the sub title stream, and the interactive object provides a graphic image on the sub title plane that lies on the main audio / video plane. On the other hand, it provides an interaction with the user. The user can set the selection, end, and playback order of the title to be played using the interactive object displayed on the screen.

In this regard, the interactive application is inconvenient to play from the beginning because it cannot be temporarily stopped during playback. Therefore, the user needs to select whether to include the interactive content or give up the contents of the interactive content in playing the content.

6A illustrates an image displayed on a screen with contents of interactive content. This is a video when the title including the interactive content and the movie content by the execution of the application is completely reproduced.

6B illustrates an image displayed on the screen without including the contents of the interactive content. Abandoning the playback of the interactive content, that is, it corresponds to the screen image when only the movie content is played by the playlist without executing the application.

7 illustrates an example of an option setting menu relating to whether interactive content is fully played.

Whether or not the application is to be executed will be determined depending on whether or not the option for complete playback of the interactive content is set. It is obvious that this can be changed to various forms as an example of the option.

On the other hand, it is possible to express various names such as the option for the full reproduction of the interactive content or the option for the interactive content reproduction.

Hereinafter, a data reproducing method of a recording medium according to an embodiment of the present invention will be described in detail. 8 is a flowchart illustrating a data reproducing method of a recording medium according to an embodiment of the present invention.

First, when the recording medium is loaded into the recording / playback apparatus, the application related to the title is executed (S10).

Here, the title refers to a playback unit forming an interface with the user. Each title is linked to a specific object. In particular, a stream related to the title recorded in the disc is reproduced in accordance with a command, a program or an application in the object.

The title may be driven by a plurality of applications, and may be composed of a plurality of playlists.

In addition, BD-J titles contain Java program information that enables high interactivity by supporting the update of titles in the recording medium or connectivity with the network among the titles in which high-definition video information is recorded by MPEG compression. It means the recorded title.

On the other hand, titles that support multi-story, director cut, etc., among the titles in which high-definition video information is recorded in the recording medium by MPEG compression, are called HDMV titles.

Corresponding interactive content is reproduced according to the execution of an application, for example, a Java application (S30). In this case, it is difficult to resume playback after pausing during the execution of the Java application, and it is necessary to restart the execution of the Java application from the beginning as described above.

In addition, as mentioned in FIG. 4, in addition to the interactive function, whether a basic expression object (for example, movie content, etc.) is played or not, the playback section is determined by a preset playlist regardless of execution of an application. .

The application may include a link relationship with the playlist and / or control information about the playlist.

When the playback pause command (S50) for the title is generated by the user, first, it is determined whether the interactive content is set to complete playback or an option for whether or not the interactive content is played (S70). At this time, if there is a setting for the complete reproduction of the interactive content, the execution of the application is stopped and accordingly the reproduction of the interactive content is also stopped. In addition, playback of the movie content is also paused (S90). Subsequently, when the playback pause is canceled, the application returns to the beginning of the title and executes the application, and the movie contents are also played according to the initial position information of the corresponding playlist.

On the other hand, if there is no complete playback setting of the interactive content, playback of the movie content is stopped while maintaining the execution of the application (S110). At this time, the position information or the reproduction information of the playlist at the time of the pause command is stored. As the execution of the application, the reproduction of the interactive content is maintained, and the reproduction is stopped only for the basic expression object or movie content. For example, only the reproduction of the interactive content is maintained while the screen is stopped.

In this case, by displaying another image on the screen, the display of the screen due to the playback of the interactive content may be restricted.

Subsequently, when the reproduction stop release command is resumed, the playback of the paused playlist is resumed (S130). At this time, when the playback of the interactive content is maintained while the application is executed, only playback of the movie content is stopped or the playback content of the interactive content is not exposed on the screen. As it continues, the use of interactive content may be substantially abandoned.

In addition, the playback pause command and the release command may occur in the same manner when the setting menu of the recording / playback apparatus 100 is executed. Also, the playback pause command may refer to a state in which a screen is temporarily stopped while playing an image.

9 is a flowchart illustrating a data reproducing method according to another embodiment of the present invention. In the embodiment of FIG. 9, for example, when the image is removed from the screen other than the playback pause, the power supply of the recording / reproducing medium 100 is stopped, or the playback of the recording medium is stopped. Embodiments relating to the case of resuming playback again are not limited thereto.

The step of executing an application related to the title (S20) and the corresponding step of playing the interactive content (S40) are the same. Thereafter, unlike the previous embodiment, the power supply itself of the recording / playback apparatus 100 is stopped. In addition, this may be the case when viewing is completed without reproducing the recording medium. In addition, it may be a case where the reproduction of the recording medium is stopped for a long time, or when the recording medium is separated from the recording and reproducing apparatus. This is not limited to the above example.

As an example, when the power supply of the recording / playback apparatus is released (S60), it is determined whether an option for the complete reproduction of the interactive content or the reproduction of the interactive content is determined (S80). At this time, if the option of the complete playback of the interactive content is set, the corresponding application at the time of resuming later playback is executed from the beginning, and accordingly, the movie content is played according to the corresponding interactive content and the initial position information of the playlist associated with the application. . When a title is played by one application and one playlist, or when a plurality of applications and playlists are provided, playback is started from the starting point of the corresponding application, and the playlist includes information about the starting point of the corresponding application. Will provide. At this point, a complete title with both interactive and movie content will be played.

On the other hand, if the option of the complete reproduction of the interactive content is not set, the identification information (for example, the recording medium ID) of the current recording medium and the reproduction information of the movie content are stored in the memory (S100).

If the recording medium is to be reproduced later, the identification information of the stored recording medium is first compared with the identification information of the currently inserted recording medium (S140). In this case, if there is no identity, the recording medium is played from the beginning. On the other hand, when the sameness is recognized, the judgment regarding the option of the full reproduction of the interactive content is again performed (not shown). If the reproduction of the interactive content is abandoned, only playback of the movie content is resumed based on the playback information of the stored movie content without executing the corresponding application (S160). On the other hand, when the playback option of the interactive content is set, the title is played from the beginning when one application exists in the first position of the corresponding application, for example, the title.

Due to the play information of the playlist (for example, the playlist mark), the reproduction of the basic expression object or the movie content may proceed from the point where it is stopped. However, since the interactive content is accompanied by the execution of the application, it is difficult to proceed from the point of interruption mentioned above.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited thereto, and various modifications and changes can be made within the scope of the claims and the detailed description of the invention and the accompanying drawings, and the present invention is also provided.
