5. EXAMPLES of carrying out the INVENTION

Optical disk with a high recording density, such as Blu-ray disc read-only (BD-ROM), rewritable Blu-ray disc (BD-RE), etc. in accordance with the invention may have a structure of files or data to control the playback of video and audio data, as shown in Fig.6.

As shown in figure 3, the root directory includes at least one catalog BD. Catalog BD includes the common files (not shown), the PLAYLIST directory, which stores the playlist files (e.g., *.mpls), a CLIPINF directory, which stores the information files clips (*.clpi), and the directory STREAM, which stores files clips audiovideofoto in MPEG2 format (*.m2ts), corresponding to files of information about clips.

The directory STREAM contains files audiovideofoto in MPEG2 format, called clips is or files clips. Audiovideofoto includes source packages audio and video data. For example, the source package of video data includes a header and a transport packet. The source package includes the number of the original packet, which is usually a sequentially assigned number that serves as the address to access to the original package. Transport packets contain a packet identifier (PID).

The CLIPINF directory includes information file clip associated with each file audiovideofoto. In the information file clip, among other things, specifies the type associated audiovideofoto, sequence information, software information and synchronization information. Information about the sequence describes the sequence of time-based input (ATC arrival time basis or on the basis of the system time (STC - system time base). For example, the sequence information indicates, among other things, the number of sequences, information about the time of the beginning and end of each sequence, the address of the first source packet in each sequence and the packet identifier (PID) of the transport packets in each sequence. The sequence of source packets in which the program content is constant, is called program sequence. Software information indicates besides what about the other things, the number of program sequences, the start address of each program sequence and identifier(s) of package(s) PID(s) of transport packets in the software sequence.

The synchronization information is called information about the characteristic point (CPI - characteristic point information). One of the forms of information about the characteristic point (CPI) is the map entry point (EP, entry point). Map entry point (EP) corresponds to the time of presentation (for example, the basic time entry (PBX) or the main system time (STC)and the source address of the packet (i.e. the number of the original package). Timestamp representation (PTS - Presentation time stamp) and the number of the original packet (SPN - source packet number) refer to the entry point of audiovideofoto; namely, the time stamp of the submission (PTS) and the related number of the original packet (SPN) indicate the entry point into audiovideofoto. Specified so the service is often called a service entry point.

The PLAYLIST directory includes one or more playlist files. The concept of the playlist was introduced to facilitate the editing/Assembly clips for playback. The playlist file is a collection of intervals playback clips. Each interval playback is called the element of play. In the file the claim playback, among other things, specifies each of the playback controls that make up the playlist, and every element of play, among other things, is a pair of points of entry and exit, the pointing position on the time axis of the clip (for example, time stamps represent time-based login PBX or timestamp STC). In other words, the playlist file identifies the playback controls, each of which specifies a clip or part of it, and identifies the information file clip associated with the clip. The information file clip, among other things, sets the playback controls in compliance with the clip in the source packages.

Files General information (not shown) provide General information to control the playback of audiofilepath recorded on the optical disk.

In addition to the illustration of the data structure of the recording medium according to the exemplary embodiment of the present invention, figure 3 shows the recording media. For example, files shared information recorded in one or more areas of General information, directory, playlist recorded in one or more areas of the directories, playlists, each playlist directory playlist recorded in one or more areas of playlists is ositelu records, etc. Figure 4 shows an example of a recording medium with a data structure in figure 3, stored on it. As shown, the recording medium includes information about the file system, the database area and the area audiovideofoto. Database region includes a region of a file of General information and information about playlists, as well as information about the clips. The scope of the shared file information and file information about playlists include files shared data stored in the corresponding area of the shared file information and directory PLAYLIST and the playlist files recorded in the relevant field information about playlists. Information about the clips have the CLIPINFO directory and recorded in the appropriate files information about clips. The area audiovideofoto contains audiovideofoto for different sections of the record.

Video and audio data are usually organized in separate sections, for example, various films, presents video and audio data are organized in different sections. Moreover, the partition may be arranged as separate chapters in much the same way as the book often divided into chapters.

Due to the large capacity of modern media with high recording density, such as Blu-ray optical disks, read-only BD-ROM) and rewritable Blu-ray discs (BD-RE), can be recorded and, therefore, reproduced from the recording media of different topics, different versions of the section or part of section. For example, one media you can record video data, corresponding to different angles of the camera's location. As another example, the media can be recorded versions of partition or its part, corresponding to different languages. As another example, the media can be written uncut version and theatrical version of the section. Or on the media, you can record a version for adults, adolescents and children (i.e., different versions of parental control). Each version, the angle of the camera, etc. correspond to the individual channel playback, and such video called video multi channel playback. Similarly, the audio data (for example, different languages, Director's notes, audio encoding formats, etc.) provide different audio streams for playback. In addition, the optical disk with a high recording density, provide the ability to have multiple graphics streams or flows of fragments of images recorded on them and played with them. Graphics streams include subsections, menus, images, etc. Such as different graphics streams can be written to the subsections for different languages. Usually the graphics stream is reproduced together with associated video and/or audio data, for example, is superimposed on the associated image.

Below will be described a data structure for managing reproduction of the multiple graphics streams to the optical disk with a high recording density in accordance with embodiments of the present invention, as well as methods and devices for recording and playback of multiple graphics streams in accordance with embodiments of the present invention.

As mentioned above, a CLIPINF directory includes information file clip associated with each file audiovideofoto, and the file of information about the clip contains the programming information. Figure 5 illustrates part of the structure of the field of program information recorded on the optical disk in accordance with an example implementation of the present invention. As shown, the length field indicates the length of the field information about the program, and the reserved_for_word_align reserved for future use. Further, the number of program sequences indicated by number_of_program_sequences. As mentioned above, the software sequence is associated with a segment, for example, video, audio or graphical representation. For each program sequence i the soft information is provided, at least the fields: SPN_program_sequence_start[i], program_map_PID[i], graphics_PID[i][stream_index], graphicsCodingInfo(i, stream_index) and graphicsDisplayInfo(i, stream_index).

Field SPN_program_sequence_start[i] specifies the number of the source packet in the source package from which the file audiovideofoto begins i-I software sequence. Field program_map_PID[i] specifies the value of the packet identifier (PID) of the transport packets, which should contain the section of the card corresponding to the i-th program sequence. Field graphic_PID[i][stream_index] specifies the value of the packet identifier (PID) of each graphics stream in the i-th program sequence. Field graphicCodingInfo(i, stream_index) specifies the encoding format or encoding of each graphics stream in the i-th program sequence. Field graphicsDisplayInfo(i, stream_index) indicates various information about the mapping for each graphics stream in the i-th program sequence. For example, the mapping information may include information about the beginning and end of the display, information about the position display for the respective image data, information about the size, etc.

Field graphics_PID can be used in several different ways. As mentioned above, the graphics stream may be a subsection, menu, image, etc. Each graphics stream may differ from one another is about value graphics_PID. Namely, in accordance with the present invention, the transport packets of the same GUI thread have the same graphics_PID, and various graphics streams have different graphics_PID.

6 illustrates a graphical representation of audiovideofoto containing multiple graphics streams, structured and managed in accordance with the exemplary embodiment of the present invention. As shown, the transport packets for multiple graphics streams are divided into groups, and groups are multiplexed with other transport groups of packages audiofilepath (e.g., video and/or autotransporte packages). Within the group of packages graphic threads packages with different graphics streams are multiplexed. As shown, each graphics stream includes transport packets having the same graphics_PID, and various graphics streams have different graphics_PIDs. In particular, figure 6 shows the source packages, but, as mentioned above, the source packet consists of a header and a transport packet.

Figure 6 depicts the first-third graphics streams #1 to#3 in the group. Each of the transport packets of the first graphic stream #1 for graphic_PID has the value 'A', each of the transport packets of the second GUI thread #2 for graphic_PID is 'In', and each transport packet is in the third GUI thread #3 for graphic_PID has the value 'C'.

Next, figure 6 shows that in one example implementation group graphics package begins with a package of graphical information. Package graphic information may contain the same graphical information about encoding and displaying the provided field program information for the graphics threads in a respective group of packets graphics threads.

7 schematically shows an example implementation of the device recording and playback of the optical disc in accordance with the present invention. As shown, audiofilereader 9 receives and encodes data (e.g., video, audio, image data of the film and so on). Audiofilereader 9 outputs the coded data together with information on coding and information about the properties of the flow. The multiplexer 8 multiplexes the coded data on the basis of information about coding and information about the properties of the stream to create, for example, a transport stream MPEG-2. The source device packaging 7 pattisue transport packets from the multiplexer 8 in the original packages in accordance with audiofileformat optical disc. As shown in figure 11, audiofilereader 9, the multiplexer 8 and the source device packaging 7 is controlled by the controller 10. The controller 10 receives user input data write operation and provides the sending information to audiofilereader 9, the multiplexer 8 and the source device packaging 7. For example, the controller 10 displays audiofilereader 9 team about the type of encoding to be performed, generates the multiplexer 8 team of traffic that you want to create, and gives the source device packaging 7 command on the format of the source package. Next, the controller 10 controls the drive 3 to record the output from the source device packaging 7 on the optical disk.

In addition, the controller 10 generates the navigation and control information for controlling reproduction of data recorded on an optical disc. For example, on the basis of information received through the user interface (for example, the set of commands that are saved on the disk provided through intranet or Internet computer system and so on), the controller 10 controls the drive 3 to record on the optical disk in one or more data structures figure 3-6.

During playback, the controller 10 controls the drive 3 to reproduce this data structure. On the basis of the information contained therein, as well as input from the user received via the user interface (for example, from the control buttons on the recorder and playback or remote control device), the controller 10 controls the di is kovodom 3 for reproducing data from the optical disk.

Reproducible source packets are received by the source device deacetylase 4 and converted into a data stream (for example, in the transport stream packet MPEG-2). The demultiplexer 5 further demultiplexes the data stream into encoded data. Audiofilereader 6 decodes the coded data to obtain the original data entered in audiofilereader 9. During playback, the original device deacetylase 4, demultiplexer 5 and audiofilereader 6 is controlled by the controller 10. The controller 10 receives user input on playback operations and provides control information to audiofilereader 6, the demultiplexer 5 and the source device packaging 4. For example, the controller 10 displays audiofilereader 9 team about the type of decoding to be performed, gives the demultiplexer 5 team of the transport stream, which is necessary to demultiplex, and generates the source device deacetylase 4 command on the format of the source package.

When in a data region Blu-ray disc read-only (BD-ROM) is written multiple image streams, the controller 10 checks the characteristic ID package (graphics_PID)recorded in each graphic package.

Next, graphics packages with package IDs IDs that matched what are the graphics stream, selected by the user through the user interface (for example, topic specific language), go to audiofilereader 6 demultiplexer 5 under the control of the controller 10.

In addition, the controller 10 searches for and verifies relevant information about the coding of image data (graphicsCodingInfo) and information about how to display image data (graphicsDisplayInfo) in the information or software package graphic information and issues a command to the decoder 6 to perform decoding and display in accordance with the encoding format and information about the mapping indicated by the information about the encoding and display of graphical data. For example, with reference to Fig.6, if the first graphics stream represents data subsection for English and this thread of topic selected by the user for display, the recording and reproducing optical disc reproduces the original packets #2, #4, #7 and so on, graphics_PID to transport packets which have the value 'A' in accordance with the selected graphics stream.

While Fig.7 illustrates the device recording and playback, it should be understood that it is possible to create a device only for recording or playback only using the parts 7, which provide the function of recording or playback.

As follows from the above description, the present invention provides methods and devices for recording media for high density recording a data structure for managing multiple graphics streams recorded on the recording media.

The above description provides methods and apparatus for playback of multiple graphics streams recorded on a medium with a high recording density, based on the structure of the data is also recorded on the medium with high recording density, to control playback of multiple graphics streams.
