The technical field to which the invention relates.

Devices and methods consistent with the present invention relate to the media and the structures of multi-view data.

PRIOR art

Multi-function digital disc (DVD), for example, are carriers of information, configured to store multi-view data. Multi-angle data is recorded on the DVD by using the method of alternation, in which the data to be written is divided into predefined modules and, in turn, are recorded. Information for search and playback perenesennyj blocks is written in the bit streams of image.

Figure 1 shows the data structure of a standard DVD. According to figure 1, a memory DVD includes scope management tools (Manager) video (VMG), which stores information titles (most of the layout of the disk of the DVD-Video format) and information menu titles, and several areas sets videotitle (VTS), which contain multiple files movies. Basically, the VMG area includes two or three files, and each VTS area includes from three to twelve files. The VTS area may include information for the title as the playback module and a set of video objects (deviations, VOBs) as information Kinotavr the taxpayer. In one VTS can be stored for several titles.

Figure 2 shows the data structure of the VMG area of figure 1. The VMG area includes the area Information of the Video Manager (VMGI), which stores additional information related to the VMG area, region deviations, VOBs, which stores the video objects for the menu, and the area of the VMGI backup. Each area exists as a single file, and in some cases, the deviations, VOBs can be omitted.

Figure 3 shows the data structure of the VTS area of figure 1. The VTS area includes the Information set videotitle (VTSI), deviations, VOBs in the quality of image data to the image menu, deviations, VOBs as information of image to set videotitle, and data backup VTSI. Selectively in the VTS area may be included deviations, VOBs to display the image menu. Each deviations, VOBs is divided into video objects (VOB) and cells as writers. One VOB contains multiple cells. The least the writer can be defined as a cell.

In DVD each level is a playback module, and the title is provided at the top level. The title is associated with one or more program Chains (PGC). PGC, which must be played first, several PGC, called Input PGC. The title can contain only one PGC, i.e. the Input PGC. The title can contain several who are PGC. In this case, where finished playing one PGC, can be selected and played another PGC from multiple PGC, and information regarding the sequence of the PGC playback can be stored in the form of commands in the DVD. The management of a playback sequence can be defined as Navigation. The team that determines the play sequence may be stored in the Software Information Chains (PGCI).

Figure 4 shows the data structure of PGC DVD. According to figure 4, PGC is stored as information structure, such as PGCI. PGCI includes precommand that stores a navigation command, postcommand and a certain amount of information program. Precommand is a command executed before the reproduction of the corresponding PGC, and postcommand is the command that will be executed after the reproduction of the corresponding PGC. Each program is composed of a number of information cells. These cells are linked on the basis of "one on one" with cells in VOB as writers. Each cell has a team of cells that are executed after the reproduction of the cell. Information PGCI describes the PGC as a writer hierarchically. Information PGCI has an information structure to associate the cell as the lowest playback module with a cell as an inferior writer. In PGC multiple cells to the to the writers interconnected, and several cells form one block angles.

Figure 5 shows a possible variant of the unit angles, containing a few cells placed in parallel. When playback is selected and reproduced one cell in the block angles. Multiple cells forming unit angles, has an identical playback time, and each cell corresponds to the data view in block angles, and the data view is divided into peremerzanie elements (ILVU) as pre-defined elements that premiani with each other and recorded in the VOB objects and Cells as the writers.

Figure 6 shows the objects VOB and Cell as writers, in the case of not adding Multiview data. According to Fig.6, each VOB is stored in a contiguous block of contiguous space recording media. In the case of Multiview data, as shown in Fig.7, VOB objects, each of which corresponds to the data view, and Cells as their lower elements, written as perenesennyj the block in which premiani elements ILVU. Accordingly, the data in one view are not stored inside a continuous recording area, and data of each view premiani and recorded in a predefined order.

Figure 7 shows a diagram in which the data of the two angles premiani and recorded in order. As the image is prohibited 7, each ILVU must have the same playback time. The size of the record length of the data may vary in accordance with the degree of data compression. To play perenesennyj data required transition module data ILVU in both cases where the reproduced data of one view, and where switching is carried out with data from one view to another view, which is then played back. For example, to reproduce data corresponding to view 1, it is required to find and play only the data ILVU corresponding to view 1. To switch to another view, when playing a data view must be taken at a specific location corresponding to the modified data view. At this time also determines the location-based navigation module ILVU.

Information location module ILVU corresponding angle for the other module ILVU another angle associated with the corresponding view, is written in the bit streams of image. As shown in Fig, deviations, VOBs as a bit stream of image, has a tiered structure, and the lowest level contains the packet (PCK), such as NV_PCK, A_PCK, V_PCK, and SP_PCK. NV_PCK is defined as a package of navigation, and as shown in Fig.9, it contains information on the size and location SML_AGL_Cn_DSTA ILVU data, the maximum ninth the angles, supported DVD. This information is information to search ILVU data for view n associated with the data ILVU, reproducible in the current time. After playing the current ILVU data, using this information you can switch the view to the desired angle for play ILVU data for the desired angle. Such information location ILVU data is multiplexed and recorded in the bit streams perenesennyj and recorded data of image.

Figure 10 illustrates the transition in the selected angles in the order of playback. According to figure 10 to perform seamless switching to play kinosobyty, where from a user in a particular location on the adopted switching command angle, formed the transition to the ILVU data desired angle after playing the current data ILUV, and you replay data ILVU desired angle.

The following describes the standard process of authoring a DVD for Multiview data. In early images taken from different angles, respectively compressed and generates bit streams having identical length play. The bit streams are interlaced, and each bit stream includes information which may relate to different angles so as to allow the switch is of the view during playback.

Information related to the alternation, is multiplexed and recorded in the data flow of kinosobyty, and consequently removed. Basically, the operation of search and playback perenesennyj blocks belonging to a certain view, or switch and then find and play perenesennyj blocks corresponding to a different angle, is processed by the processor of the playback devices through software. The software accesses ParameterName the unit is playing in the current time, receives the location information on the required peremienko unit for playback, and transmits the location information in the data reader. Also, the compressed and encoded data of the image processed in the demultiplexer of kinosobyty. Accordingly, the process required to extract the information of the location of the data of image and information transfer location to the processor.

In addition, when multi-view data is divided into pre-defined elements, interspersed and are retained even in the case where the sequentially reproduced data from one angle, continuously need to change the location of the playback consequently for the th read data, since the corresponding data is not recorded consistently. Also, there is a problem in that although it may require significant time to change the location, in relation to, for example, optical drives or hard drives, the bit rate of the compressed streams of bits to compensate for this time is limited.

The IMPLEMENTATION of the INVENTION

Will now be considered in detail embodiments of the present invention, examples of which are illustrated in the attached drawings, in which identical reference position are identical to the elements. The following describes embodiments of to explain the present invention according to the drawings.

According to a variant implementation of the present invention proposed a medium on which information regarding the transition points for playing data of each view and/or playback data another angle during playback data of the original view recorded in the memory medium, separate from the field of multi-view data of image. According to the aspect of the present invention of image data for a given view can be stored as audio-video (AV) stream of the clip AV streams of video for different recur the s can be individually divided into smaller peremerzanie blocks and premiani with each other. According to another aspect of the data for each view can be recorded using the recording method of separation. Information of the transition points for the search of image data for each view is stored in a memory area separate from the data area of the image. That is, information for referring to the various views provided in the region separate from the region of the AV streams of the clip.

To switch from one angle to another angle, according to the aspect of the present invention, the data view are classified as the corresponding elements of the transition (JPU), with the address of the beginning of each transport module designated as the point of transition, and information regarding the transition point is recorded as a separate additional information. In the case where data of one view is divided into peremerzanie blocks and premiani with data from another perspective, peremerzanie blocks can act as navigation elements.

To perform the operation described above, a variant of implementation of the present invention may contain the following components:

(1) the compressed and encoded audio-video (AV) streams clip for the respective angles,

(2) an information file of a clip having information such as attribute information coding for the AV stream, clip,

(3) Punchthe (Play Item) to set the time according the interval of play between the time of INPUT (IN-time) and time (OUT-time) of a clip,

(4) Spisone (Play List)that contains one or more Puncture, and

(5) the schema matching transition points, which stores the location of the transition points.

Multiview data refer to the data of the image containing several elements play a certain point in time. That is, the multi-view data is data of the image that are captured at a specific point in time simultaneously using multiple cameras, with each camera, for example, is kind of different from the other perspective. The audio data can be shared for each view or can be created in a special way for each view. Data of image that can be played on the same time scale, defined as multi-view data, and content created using Multiview data, defined as multi-view content.

Because the size of image data is very large, the data of image is compressed and stored/transmitted as compressed bit streams. As an illustration, the clip may correspond to the writer, and Spisone and Punchthe correspond to modules playback. The clip may correspond to a cell as a writer, for example, a DVD, and Spicara the Oia and Punchthe comply with the program and the cell as modules DVD playback. The object containing the AV stream, clip information clip, can be defined as the clip, and Punchthe may cover a portion of the clip or the entire clip. Additional description regarding this below.

The media recording information according to a variant implementation of the present invention, stores the AV streams, that is, the AV streams of the clip as the clip. The AV stream, the clip can be divided into peremerzanie blocks that must be premiani or recorded in a continuous area of memory. Each AV stream is compressed and recorded to reduce its size. For playback of the AV streams of the clip you want the characteristic information of the compressed data of image. For this reason, for each AV stream, clip information is provided clip. Information clip contains audio and videotribute for each AV stream, clip and Schema matching Entry Points, in which information is stored the location of entry points, providing the possibility of random access to pre-defined intervals. In MPEG, which is mainly used as standards for the compression of image, entry points correspond to the locations I-images, on the basis in which the compression of the intermediate images. For example, the Schema matching Entry Points used by the search time to search before artelino a certain elapsed time point after the start of playback.

11 depicts the dependence of the locations between the modules, transition, transition points and entry points in the AV stream clip to illustrate aspects of the present invention. As shown in figure 11, where the AV stream of the clip are of image data corresponding to one angle among multi-view data, the AV stream, the clip is divided into several elements of the transition. Each point is the beginning of each module transition is a transition point. The transition point can be the location of the AV stream, the clip during playback of the AV stream, the clip is moving outside to play another AV stream, the clip corresponding to the data of the image having a different angle or location of the AV stream of the clip, in which the transition is performed during playback of another AV stream of the clip. The transition point may be identical to the entry point. According to the aspect, since the entry points are, for example, approximately every 0.5-second time interval, with seamless playback of all the entry points may not be used as transition points. As shown in figure 11, one transport module may include multiple entry points. The transition point can specify the first point of entry from multiple entry points within the transport module.

Fig depicts the structure of the data is multiple AV streams clip for Multiview data, moreover, the AV streams of the clip is not premiani, to illustrate aspects of the present invention. As shown in Fig corresponding to the AV streams of the clip are recorded individually in a continuous recording area, where each AV stream of the clip corresponds is different from the other view. AV streams of the clip have the same number of transition points and virtual interrelated. That is, the AV streams of the clip is divided and recorded separately in a continuous region of memory, but connected to each other at the transition points as locations, indicating identical time playback. Accordingly, in the case of playback during playback, the current AV stream another clip AV stream, clip, can be made sequential playback by searching transition point of the next module of the transfer and playback of the next module move to another AV stream, the clip after the completion of the playback of the transport module of the current AV stream of the clip. Fig illustrates the sequence of play, which recreates the angle 3, then played back view 1, and sequentially reproduces the angle m. User input for switching angles can be processed on the basis of the elements of the transition.

Fig depicts the structure of the data, where appropriate AV streams clip premiani and recorded, for which illustratie aspect of the present invention. As shown in Fig, where the AV stream of the clip, as the data in one view, is divided into smaller peremerzanie modules that must be premiani with data from other angles, the transport module acts as perenesennyj module, and the point of beginning peremienko module acts as a transition point and, at the same time as the first entry point of the corresponding peremienko module. One perenesennyj module can contain multiple entry points for random access. According pig, the transition may take place at some point move even during the playback of the data in one view. Where AV streams clip premiani, search and playback peremienko module corresponding to the data current view. Information transition point is used to play, after playing peremienko module, next peremienko module belonging, for example, to the data the same angle, that is, data from the current view. The location of the next peremienko module is detected by using the information of the transition point. Where the user selects one view from another angle, in other words, data from one view data from a different perspective, information transition point is also used to search for the location of the appropriate peremienko module data the underwater view.

Fig illustrates the correlation between Speccompliant, Punktown, information of the clip AV stream clip. As shown, the clip refers to the AV stream, clip information of the clip AV stream, clip. According pig, Spisone is the base module for playback. The storage medium according to the present invention, can be stored for several Spiskovoy. One Spisone may contain several interconnected Punktown. Punchthe can be used to denote the start time and playback end time of the playback of the clip. The location of the relevant part (Punchthe) valid in the AV stream, the clip can be detected by using the information of the clip.

The storage medium according to the present invention, configured to provide random access, can perform sequential playback even in the discontinuous memory areas by changing locations playback in a predetermined time. This change locations defined as "the transition". Basically, electronic media, such as memory, does not require a predefined time of transition, but the media, such as optical is the first disk, with respect to which the head is moved to read the data requires significant time for the operation of the transition. Also, even in case of reading and reproducing a continuous region of memory component is required to compensate for differences between reading speed and the playback speed, where the speed of reading of image data from storage media differs from the playback speed of data read in the image. As such a component of compensation can be used a buffer of image. Prepared buffer image having a predetermined size. The buffer is filled when reading data at a predefined speed, and from this time you play. Can control the speed of reading data to prevent overflow or buffer underrun of image. When using a buffer of image sequential playback is possible even where the data of image is recorded with a variable bit rate (VBR).

On Fig shows that the data stored in the buffer of image is reproduced so that in the course of time the operation switch of image data reproduced without breaking even where playing is seeking a transport module and then formed a transition in the AV stream, clip, stores data of the image for another view. This operation is completed, and starts the playback module transition to the next view before it can happen a buffer underrun. In the case of a playback device, requiring time operation, assuming that the worst time of the operation switch is T_JUMP, the read speed is V_R, and the playback speed of image data is V_0, the size of the transport module must satisfy the condition: the size of the transport module >V_R*V_O*T_JUMP/(V_R-V_O). Also, the buffer must meet at least the following condition on the size: the buffer Size (B)>V_O*T_JUMP.

Playback can be played one of the AV streams of the clip (not shown)belonging to this block angles. AV streams of the clip, i.e. the clips 2, 3 and 4, forming a block of angles, may be identical to the time the play is to be placed. Although not shown, according to an aspect of the present invention, the clips are marked for Puncture forming unit angles, include information of the transition points as additional information in the memory area, separate from the data area of the image, that is, the AV streams of the clip. According to various aspects of the present invention, the AV streams of the clip can be premiani with each other or divided and recorded in a continuous area of memory, that is, each of the AV streams of the clip is recorded continuously without alternation with other AV streams of the clip. Where AV streams clip interspersed, each AV stream, the clip is divided into smaller elements, i.e. peremerzanie elements to interleave with separate AV streams of video for other angles. In the absence of alternation, as shown in Fig, the clips 2, 3, 4 are recorded, respectively, in a continuous region of memory. These clips are provided as well as Clips 1 and 5, which do not form a block angles.

According pig, in the case in which the corresponding clip is a clip to view, create information schema matching transition points (JPMap) and is included in the clip information additional what about the basic information and schema information of the matching entry points (EPMAP). According to a variant implementation of the present invention, the information of the transition points is recorded in the memory area, separate from the data area of the image. According to the aspect, since the information of the transition points has a strong correlation with the data of image information of the transition points is included in the clip information. Information of the clip is additional information for the AV stream of the clip. According to various aspects of the present invention, data of image for different angles can be represented by AV stream clip or more AV streams of the clip. Basic information may include the following information:

- version number (version number): version information file clip

- EPMap_start_adress (start address EPMap): relative byte number from the first byte of the file information of the clip information indicating the address of the beginning of EPMap,

- JPMap_start_address (start address JPMap): relative byte number from the first byte of the file information of the clip information indicating the address of the beginning of the JPMap, and if this value is null, then the corresponding clip is the clip you want to view, and information JPMap does not exist, and

- ClipInfo (clip): stores the attributes of a file of the AV stream of the clip relating to the information file of the clip.

Information EPMap contains information time and location of the entry point, obespechivayu the possibility of random access. Basically, the playback time is the Time specified in MPEG, and information location is the number of bytes number of sectors or, where information of image encoded Transport Streams with MPEG, the number of packets of an MPEG-TS. Information JPMap contains the information of the transition points for the virtual link clip with clips from other angles, where the clip meets the clip for the data view. According to the aspect, the number of transition points and the corresponding information of the transition points is included in the information Manager navigation information JPMap. Information points of transition contains information for finding the location of the transition point from the location of the beginning of the clip. According to the aspect, this information locations is the number of bytes or the number of sectors. According to another aspect, the information of the location may be the number of packets MPEG-TS, where the information encoded in the Transport Streams MPEG.

Fig depicts a data structure for providing transition points, according to another variant implementation of the present invention. According pig, the information of the transition points is included in the information EPMap. As described above, the transition point may be identical to the entry point as the point of random access, where the film image coded what exploits run-time-space compression, such as MPEG. Accordingly, information regarding the transition points can be simply recorded by inserting the information regarding the entry point information as to whether the corresponding entry point, as a point of transition. According to the aspect, each element from some set of clip information corresponding to the AV streams of the clip may include information EPMap containing information on entry points and as to whether each of the entry points as well as the transition point.

According Fig where one Spisone which correspond to one view, Punchthe belonging Spiskowa, not to generate a block angles. As shown in Fig, information regarding view, presents relevant Speccompliant, is separately recorded. Appropriate Spisone is reproduced in accordance with the angle or changing the view by the user.

As described above, the data of image for one angle can be separated and premiani with separated data of the image for another view, or every of image data can be recorded in a continuous area of memory. Locations of communication of image data representing the corresponding angles are the transition point. Management of the transition points is carried out as additional data in the memory area, separate from the data area of the image. In addition to information for many angles can be provided with information of a playback module for playing the respective modules account for the data of image. According to a variant implementation of the present invention, for reproducing multi-angle data, the playback device performs the following operation.

Since the information for transition points for search and playback the data view is recorded in the area and memory separate from the data area of the image, information for transition points can be read and stored in memory prior to playback with media relevant data of image. Then tracked data corresponding angle, or tracked data other appropriate angle corresponding to the switching angle, for example, by the user. According to the aspect, the clip information contains information of the transition, communication information for the data of the image forming unit angles. Accordingly, where at a certain moment of time required switching angles, after performing playback to the nearest transition point of the reproduced data reproduced remaining information of the image after the corresponding transition point of image data for another angle.

Where relevant data view not premiani and recorded in a continuous memory space, even if the data are Multiview of image data, the data is read and reproduced from a continuous memory space, where there is performed switching angles. Therefore, multi-view data of image can be encoded as basic data of the image, for example, odnorotornyj Yes the basic image. Accordingly, this aspect does not require separate data or restriction on coding for sequential playback view, as in the alternation.

As the informational structure of the playback module, where information representing multiple perspectives, recorded in a way that Punchthe belonging Spiskowa is a block angles, and where required switching angles during playback of the AV stream, clip belonging to the block angles, after playing to the nearest transition point from the current location of the AV stream, the clip for the currently playing view, playback continues from the point after the corresponding transition point of another AV stream clip to another angle, the switching angles of view (current view) to another view is requested, for example, by the user. According pig, there is provided a separate Specchia for the respective angles, switching camera angles during playback of the current SpeciaI is reproduced in other Spisone corresponding to the switch.
