Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 is a diagram illustrating an image processing system according to an embodiment of the present invention.

Prior to the specific description, the image processing system 90 according to the embodiment of the present invention can operate in various situations. For example, when the user reproduces the optical disc 100a in the image processing apparatus 100 and views the image through the image display apparatus 110_1, the image processing system 90 may include an image processing apparatus 100 When the user attempts to copy a specific content to the user device 110_2 through the content list displayed on the video display device 110_1 or when the content provided by the content management device 130 is copied to the optical disk 100a When you want to save, you can work in various situations.

1, an image processing system 90 according to an embodiment of the present invention includes an image processing apparatus 100, an image display apparatus 110_1, a user apparatus 110_2, a communication network 120, (130).

Here, some of the components such as the communication network 120 and the content management apparatus 130 may be omitted and configured to include only some or all of them, for example, when performing only a specific operation such as a copying operation, ) May be integrated with the image display device 110_1 and the like, and the description will be made in order to facilitate a sufficient understanding of the present invention.

First, the image processing apparatus 100 is an optical disc 100a, for example, a BD (Blue-ray Disk), which is an optical recording and reproducing apparatus capable of reproducing files based on, for example, MPEG2 TS, As the file format, for example, it is possible to include a media data reproducing device such as a computer or a mobile phone capable of reproducing a file based on an ISO file. Such devices can be regarded as reproducing contents according to different file format standards, and two devices can be distinguished from each other by the terms 'optical recording' or 'media data'. Of course, in the embodiment of the present invention, an ISO file different from the standard of the optical disc 100a is taken as an example for convenience of explanation, but any format file format may be used.

It is considered that the file structure of the optical disc 100a solves the contents of various file formats in the various types of image processing apparatuses 100 as described above. In other words, the optical disc 100a according to the embodiment of the present invention can reproduce ISO file-based media playback file (s) in the standard of the optical disc 100a so that contents of various file formats can be reproduced in various kinds of image processing apparatuses 100, And a file structure for supporting the. In addition, for example, a separate file is included to drive the optical disc 100a of the Blu-ray standard in a media data reproduction apparatus that does not use the Blu-ray standard to perform a copy operation or the like.

As will be described later in detail, it is possible to access media data files for media playback through a PlayList, a PlayItem, and ClipInfo in a Blu-ray application standard, It allows access to the actual media data through the description of the object structure. To this end, it is possible to access the ISO file through the change of the PlayList, PlayItem, and ClipInfo stages of the Blu-ray standard, and to provide a separate Media Info File containing the information about each ISO file .

In other words, the optical disc 100a includes a reproduction management file which is a standard of the optical disc 100a, that is, a PlayList, a PlayItem, a ClipInfo file, and a reproduction management file of a standard different from the standard of the optical disc 100a, , The PlayItem, and the ClipInfo file may have access information for accessing the ISO file. The optical disc 100a also includes additional information files that are executed to display the additional information on the screen of the video display device 110_1 so that the content conforming to the standard of the optical disc 100a and the content conforming to the ISO standard can be selected by the user . Here, the additional information may include various information such as a file format, a country, and whether or not copying is possible. More details on this will be discussed later.

The video display device 110_1 includes various devices such as a TV, a computer monitor, a notebook, and a mobile phone. The video display device 110_1 is a content display device that displays a content image reproduced (or processed) in the image processing apparatus 100, that is, a content in the optical disc 100a or a content provided in the content management apparatus 130 via the communication network 120 Can be displayed on the screen. At this time, the content displayed on the screen may be content based on, for example, the Blu-ray standard, and may be content based on the ISO file format. In other words, since the image processing apparatus 100 operates in accordance with the standard for reproducing the optical disc 100a in the optical recording and reproducing apparatus, it is impossible to implement the content based on the ISO file format. However, in the embodiment of the present invention, It is possible to access the ISO file using the access information to access the file, thus making it possible to implement the content constructed based on the ISO file format.

When the optical disc 100a having a file structure conforming to different file format standards is inserted as in the embodiment of the present invention, the image processing apparatus 100 may process the network-based media data, It is possible to drive the optical disc 100a to reproduce contents according to various standards. However, when the content management apparatus 130 produces and directly provides a file of a specific standard, it is preferable that the file standard and the image reproducing apparatus 100 conform to the same standard. In other words, when the content management apparatus 130 provides ISO file-based content, the image processing apparatus 100 is preferably a media data reproduction apparatus. However, when the image processing apparatus 100 changes the file format structure so that the corresponding ISO file can be reproduced by the optical recording / reproducing apparatus, the corresponding ISO file can be reproduced.

When the image processing apparatus 100 is a media data reproducing apparatus, the image display apparatus 110_1 can display contents according to the standard of the optical disk 100a and contents based on the ISO file on the screen and display additional information . Here, the additional information may be information such as path information for the ISO file, permission information such as age and country, attribute information such as file format and resolution, content information such as supportable speech language and reproduction time, Related information, access proposal-related information, additional content information, and the like. Such additional information can be displayed on the screen according to the execution of the Media Info File in the optical disc 100a, that is, the additional information file. For example, in the case of copying a specific content of an MPEG TS or an ISO file structure, if copying is indicated on a part adjacent to the name of the content on the screen, the image processing apparatus 100 selects the content, Or to a user device 110_2, such as a cellular phone.

Practically, the image processing apparatus 100 executes an index file in the optical disc 100a and provides a menu screen to the image display apparatus 110_1 in the form of an interface window so that the user can select one of a plurality of contents. The menu screen can be provided with a variety of visual information, for example, by the execution of a Java application. Accordingly, the additional information screen according to the execution of the additional information file according to the embodiment of the present invention may be provided as a sub screen of the menu screen or may be provided as an independent screen according to a user's request.

The user device 110_2 may correspond to a device of the same type as the video display device 110_1. However, if the video display device 110_1 displays a content image reproduced in the video processing device 100 on the screen, the user device 110_2 can be a portable terminal device such as a mobile phone, a DMB, a PDP, a tablet PC, and a PDA , And a device capable of copying and storing contents in the optical disc 100a. Of course, it is preferable that the image processing apparatus 100 and the image display apparatus 110_1 are computers such as a desktop and a laptop. When the image processing apparatus 100 and the image display apparatus 110_1 are used as computers, It may be possible to copy and store the contents of the optical disc 100a desired by the user in the internal memory of the image processing apparatus 100. [

The communication network 120 includes both wired and wireless communication networks. Here, the wired network includes an Internet network such as a cable network or a public switched telephone network (PSTN), and the wireless communication network includes means such as CDMA, WCDMA, GSM, Evolved Packet Core (EPC), Long Term Evolution (LTE) to be. Therefore, when the communication network 120 is a wired communication network, the access point can access the exchange of the telephone office, etc. In the case of a wireless communication network, the access point can access the SGSN or GGSN (Gateway GPRS Support Node) Station Transmission), NodeB, e-NodeB, and the like.

Also, the communication network 120 includes a small base station (AP) such as a femto or pico base station installed in the building. Here, the femto or pico base station is classified according to the maximum number of the classified image processing apparatuses 100 connected to the small base station. Of course, the AP includes an image processing apparatus 100 and a short-range communication module for performing short-range communication such as ZigBee and Wi-Fi. In the embodiment of the present invention, the short-range communication includes a wide variety of radio frequency (RF) and ultra wideband (UWB) communications such as Bluetooth, Zigbee, IrDA, UHF and VHF Standard. Accordingly, the AP can extract the location of the data packet, specify the best communication path to the extracted location, and forward the data packet to the image processing apparatus 100 along the designated communication path.

The content management apparatus 130 may be a server operated by a content provider or a server operated by an information portal company such as Naver and Daum. The content provided by the content management apparatus 130 may be various contents conforming to different file format standards. The contents of the various standards are provided to the image processing apparatus 100 and can display the corresponding content image on the image display device 110_1 through reproduction. For example, when the image processing apparatus 100 is an optical recording and reproducing apparatus, it is preferable that the image processing apparatus 100 is a content conforming to a file structure based on MPEG TS, and that the image processing apparatus 100 is a media data reproducing apparatus It is preferable that the content is in accordance with an ISO file structure which is a network-based media data file. The content management apparatus 130 may also be able to (copy) and store some content in the optical disc 100a provided by the image processing apparatus 100 through communication with the image processing apparatus 100. [

As a result of the above configuration, the image processing system 90 according to the embodiment of the present invention can support reproduction of a plurality of file formats based on, for example, the ISO file format in the Blu-ray disc standard. For example, support for a number of file formats, such as Advanced Video Coding (AVC) file format based on the ISO file format, Scalable Video Coding (SVC) file format and UV file format, will become possible. In addition, by using the Media Info File (i.e., the additional information file), the ISO-based media file format and additional content existing in the disc can be accessed without following the Blu-ray disc standard, It is possible to enjoy the content even in the playback apparatus.

2A and 2B are diagrams illustrating an MDAT access method and an ISO ClipInfo data structure by adding access information to a ClipInfo file.

Referring to FIGS. 2A and 2B, the optical disc 100a of FIG. 1 according to the embodiment of the present invention stores a reproduction management file based on a Blu-ray standard and an ISO file structure in a file structure as shown in FIG. 2A .

First, a BD playback structure is briefly described. A BD application can be accessed in units of Playlist. The playlist is a file that allows media data to be edited and viewed in various scenarios according to the intention of the user or the content creator without modification of the media data itself. The Playlist has a continuous playback time flow and the Playlist is composed of a plurality of PlayItems as shown in FIG. 2A.

As shown in FIG. 2A, the PlayItem is an operation description for a continuous time flow in one piece of media data, that is, a unit playback period having individual In time and Out time. The PlayItem is a structure that describes the continuous time flow on the media data. As a detailed description, the PlayItem is used to access the main video, audio, subtitle, menu, additional video, Also included.

Structurally, the existing ClipInfo at the bottom of the PlayItem is one file corresponding to one media data file (XXXXX.m2ts file composed of MPEG 2 TS in the case of Bluray standard). For example, if a TS file 00000.m2ts exists, there is one ClipInfo file 00000.clip for that file. The ClipInfo file includes time information corresponding to In time and Out time described in the PlayItem, time to space mapping information on the position on the m2ts file, and information necessary for normal decoding.

Of course, through the PlayList, the PlayItem, and the ClipInfo, the media data can be described in various scenarios according to the intention of the content creator.

In the meantime, if a conventional ISO file reproduction structure is briefly described, only a movie box (hereinafter referred to as MOOV) containing all the MetaData information necessary for media data reproduction and a video file , And a Media Data Box (hereinafter referred to as MDAT) in which media data such as subtitles are included.

Here, MOOV is composed of several tracks again. Each track contains description information about processing method, expression method, approach method, media-to-media sync method, and edit processing for each media data. Tracks describe how each media data is accessed, how it is processed, and how it is presented to the user. The Track has a Sample Table Box containing information for accessing actual image data existing in the MDAT.

The Sample Table Box contains access method and related description information for the position in the MDAT for the playback time for each playback time.

2A shows a method of accessing a media data file for media playback through a PlayList, PlayItem, and ClipInfo in a Blu-ray application standard, and a method of accessing an ISO file through a change of a ClipInfo stage among them.

Referring to FIG. 2A, a method for accessing an ISO file is described and added to a ClipInfo file describing a method of accessing a media data file (m2ts file) with respect to time on a Blu-ray standard according to an embodiment of the present invention . As shown in the example of the ISO ClipInfo file of FIG. 2B, when the Clip Type is ISO file in PlayItem, it is possible to generate a separate ISO ClipInfo file for an ISO file having a different interpretation. That is, it is also possible to provide a separate file in which the file name is the same but the contents and description of the internal structure are different. The case where information is added to ClipInfo and the case where ClipInfo for new ISO is generated will be referred to as ISO ClilpInfo hereinafter.

As shown in FIG. 2B, the ISO ClipInfo includes a method for accessing the media data in the MDAT corresponding to the media playback time and information necessary for decoding. The ISO Clip shown in FIG. 2A is an ISO Clip that includes access information to the MDAT in the ISO file. The Clilp Info file shown in FIG. 2A indicates that a plurality of Clip Info files access one MDAT area, which can be generated by including video, audio, and various contents data in one MDAT box.
