5. PREFERRED embodiments of the PRESENT INVENTION

For a more complete understanding of the present invention will now be described examples of its implementation with reference to the accompanying drawings.

The recording medium of high density, such as an optical disk with a high recording density, such as Blu-ray disc read-only (BD-ROM, BD-RE, etc. in accordance with the invention may have a structure of files or data to control the playback of video or audio data, as shown in figure 1. Some aspects of the data structure in accordance with the present invention, is shown in figure 1, are the same as in the well-known standard BD-RE, so these aspects will be analyzed, but details will not be described.

As shown in figure 1, the root directory contains at least one catalog BD. Catalog BD includes the common files (not shown), the PLAYLIST directory in which the files are stored playlists (for example, *.mpls), a CLIPINF directory, which stores the information files clips (*.clpi), and the directory STREAM, which stores files clips audiovideotoday in MPEG2 format (*.m2ts), corresponding to the information files clips.

The directory STREAM includes files audiofilepath in MPEG2 format, called streams files clips or just the files clips. Audiovideofoto contains the source packages of video and audio 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. The transport packets includes a packet identifier (PID). The bundle identifier specifies the sequence of transport packets that belongs to the transport package. All transport packets of the same sequence have the same bundle identifier.

The CLIPINF directory includes information file clip associated with each file audiovideofoto. The information file clip indicates, among other things, on the type associated audiovideofoto, contains information about the sequence, information about the program timing information. Information about the sequence describes the sequence in time of arrival (ATS) and systems the mu time (STC). For example, the sequence information reflects, 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 a package ID for the transport of packets in each sequence. The sequence of source packets in which the program content is constant, is called program sequence. Information about the program reflects, among other things, the number of program sequences, the start address of each program sequence and identifier(s) pack (s) for transport of packages in the software sequence.

Timing information refers to information about the characteristic point (CPI). One of the forms of characteristic points is the map entry points (EP). Map entry points corresponds to the time stamp of the submission (e.g., time of arrival (PBX) and/or system time (STC)and the address of the original packet (i.e., the number of the original package). Timestamp representation (PTS) and the number of the original packet (SPN) associated with the entry point in audiovideofoto; namely, the time stamp of the submission and the associated number of the source packet indicate the entry point on audiovideofoto. The package, which indicates, is often referred to as Aceto entry point.

The PLAYLIST directory includes one or more playlist files. The concept of a playlist introduced to facilitate the editing/Assembly clips for playback. The playlist file is a collection of intervals playback clips. Each interval of the play belongs to the element of play. The playlist file specifies, inter alia, each of the playback elements that make up the playlist, and every element of play, among other things, is a pair of start and end points indicating the position on the time axis of the clip file (for example, timestamp representation based on the arrival time, or timestamp). The playlist file may also include a sub playback, also have a pair of start and end points indicating the position on the time axis of the clip file. In other words, the playlist file specifies the playback controls and the sub play, each of which specifies a file of a clip or part and determines the information file clip associated with the clip file. File information about the clip is used, among other things, to put into correspondence with the elements playing the clip file from the source package. Lists vos is proizvedeniya can also include labels, pointing to specific places (for example, a specific address in the clip file.

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 in accordance with the exemplary embodiment of the present invention figure 1 shows the area of the recording media. For example, files shared information recorded in one or more areas of General information, directory of playlists recorded in one or more areas of the directory of playlists, each playlist directory playlist recorded in one or more areas of playlists on the recording media, etc. Figure 2 illustrates an example of a recording medium on which is stored a data structure of Figure 1. As shown, the recording medium includes information about the file system, the database area and the area audiofilepath. The scope of the database includes information about the files General information about the playlists and information about the clip. Region file information General information and playlists contains files shared data stored in files General information and directory PLAYLIST and the playlist files recorded sootvetstvujushej information about playlists. Information about the clip contains the CLIPINFO directory and recorded in the appropriate files information about clips. The area audiofilepath contains audiovideofoto for various record sections.

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

Due to the large storage capacity of the newest of the recording media of high density, such as optical discs BD-ROM and BD-RE, on the recording medium can be recorded and, therefore, reproduced with different sections, different versions of the same section or part of section. For example, one recording medium can record the video data, corresponding to different angles of the camera. As another example, the recording medium can record the version of the section or its parts, corresponding to different languages. As another example, the recording medium can be recorded and directing theatrical release section. Or on the recording medium can record the version of the section or parts thereof for adults, adolescents and children (i.e., different versions for parental control). Each version, the angle of the floor is the position of the camera and tpotential individual channel playback and video in such cases, refer to the video data and multiple channels of playback.

Due to the large storage capacity of the newest of the recording media of high density, such as optical discs BD-ROM, static images or footage can be recorded on a recording medium and reproduced it in an organized manner and/or in dialog mode, for example, in the form of slide shows. The data structure for the management of static images for the recording media of high density in accordance with embodiments of the present invention will be described together with the methods and devices in accordance with embodiments of the present invention for recording and playback of still images.

3 and 4 illustrate an example implementation of a data structure and method for static images for the recording media of high density, such as BD-ROM. As shown in Figure 3, the flow of images and streams of related data (e.g., threads, graphics and subtitles) are combined into packets packetized elementary stream (PES) based on the static images. Namely, each elementary stream is stacked in packets packetized elementary stream. Package packetized elementary stream for a stream of still images including the et one static image, and the corresponding packets packetized elementary stream related data include auxiliary data corresponding to the static image (for example, for playback synchronously with the corresponding static image). As additionally shown in Figure 3, in the header area of each packet packetized elementary stream included timestamp representation. As discussed below, timestamps, views can be used to calculate the duration of the presentation of static images and/or to communicate with the playlist. A static image with accompanying data to be reproduced synchronously with him, are grouped into a block of static images. Block-based static image stream of still images and streams of related data multiplexer in the file static images of traffic flows in the MPEG2 format.

Figure 3 also shows the file information about the clip corresponding to the file static images. File information about the clip includes a map of entry points. Single entry point (entry point No. 1˜ # k) on the map input points contain the corresponding navigation information for accessing the entry of the title of the corresponding block of static images. N the example, the navigation information includes information about the initial positions of the entry points for the number of the source package (SPN_EP_Start)indicating the starting position of the record of the corresponding block of static images, but also includes the time stamp represent a block of static images. As discussed in detail below, timestamps, views can be used to calculate the display duration of each static image.

Figure 4 illustrates a playlist for managing playback of the file images discussed above in relation to Figure 3. As shown, the element of play in the playlist contains information about the start time (IN_time) and end time (OUT_time), relating, respectively, to the initial position and the final position of static images in the file of still images for playback. As shown, a time stamp of view issued by an element of play in the form of information about the start time and end time associated element play with the map entry points of the file information about the clip corresponding to the flow of static images. The initial timestamp of view is a point in time representation of the first image to be reproduced, the cat is which in this example corresponds to the static image, the specified first point of entry No. 1, and the ending timestamp of the view is the point in time of the presentation of the static image to be reproduced, which in this example corresponds to the static image, the specified k-th entry point (entry point # k).

Subcell playback (SubPlayItem) in the playlist contains information about the start time for subcell play and information about the end time for subcell play intended for a separate audio file to be reproduced in accordance with the file images. Audio data can be played back in synchronization mode or without synchronization with the corresponding static images.

Figure 5 shows that the time stamp of the views recorded in the packet packetized elementary stream that has a value that is proportional to, for example, to reference a well-known software time PCR. If a static image is of unlimited duration, the countdown program time remains the same, and a package of packetized elementary stream corresponding to the static image is recorded is proportional him timestamp representation. Accordingly, identical to lie to the fair a mark of submission is recorded in the packet packetized elementary stream static images with unlimited duration views and in the packet packetized elementary stream next static image, as shown in Figure 5. For example, the playback device can calculate the difference between the time stamps of the views recorded in the following entry points or subsequent packets packetized elementary streams static images, to determine the duration of the presentation of the first of the two consecutive images. If the difference between the time stamps of the representation is equal to zero, the playback device plays the corresponding static image with unlimited duration representation in the sense that a static image is displayed until then, until it receives a user input command to terminate. Otherwise, the playback device data from an optical disc reproduces the static image within the calculated time.

In other words, the playback device during, for example, play slide shows from still images to decide whether the duration of presentation of each static image limited or unlimited. If duration is unlimited, the playback device does not increase the reference ol the software time and retains the previous value. On the contrary, if the length of the representation is limited, the playback device performs a series of operations by the usual increase in the reference software of time.

Figure 6 is a diagram of the structure of the device for optical disk in which is applied the present invention. As shown, the device for optical disk includes an optical head 11 for reproducing data from the optical disk. The playback system video (VDP) 12 controls the playback operation data by the optical head 11 and demodulates the data reproduced by the optical head 11. The playback system video 12 creates audiovideofoto, which can also be served in the d / a Converter 13 for forming the analog version of audiovideofoto.

The playback system video 12 controls the optical head 11 and demodulates the reproduced data based on user input received from the user interface, as well as the navigation and control information recorded on an optical disc in accordance with the present invention. For example, the playback system video 12 accesses the playlist and map entry points included in the information file of the clip, as described above, with the aim of play is of static images. That is, the playback system video 12 reads a static image, image data and subtitle data of each block of static images in accordance with the procedure of entry points (EP №1, №2, ...), recorded in map entry points. The system then play video 12 performs a series of operations for playback of slide shows that can be played with limited or unlimited duration in accordance with the time stamps of the representation contained in the entry points of the map entry points, or packetized elementary streams static images, as described above. If you define an unlimited duration, the corresponding static image is displayed until, until there is a user input, for example, through the user interface system play video 12.

In another embodiment of the present invention, as shown in Fig.7. in order to separately reproduce the static image with distinctive attributes view, many elements of the play is recorded and managed in the same playlist to control playback of the file is a static image.

For example, the first element of play can be associated with data flows blocks article the static images with unlimited duration views then as the second element of the playback can be associated with data flows blocks of static images with limited duration of the presentation.

Therefore, when the playback system video 12 device for reproducing data from an optical disc plays back streams of data blocks of static images associated with the first element of the playback, the playback system video 12 plays back the stream data of each block of static images and waits for user input from the keyboard.

On the other hand, when the playback system video 12 reproduces data streams blocks of static images associated with the second element of the playback, the playback system video 12 plays back the stream data of each block images and, as described above, performs a series of operations to reproduce the stream data of the unit images in accordance with either the expiration of the duration of the representation defined by the difference of the timestamps of view in the entry point (or packetized elementary streams), or by receiving user input from the keyboard.

Although the duration is specified as an example of the attribute view, it should be understood that the present invention is not about what ranchero this example.

Another example implementation of a data structure and method for static images the recording media of high density in accordance with the present invention is illustrated in Fig. As shown, to control the playback of the file static image element of the play is recorded and managed in the playlist. Flags of the length, each of which specifies the playback of stream data block images associated with each entry point, with limited or unlimited duration views are recorded and managed in the form of a list within the element playback.

In this case, the playback system video 12 may check the checkbox duration associated with the entry point corresponding to the specified static image; if the check box duration is a value indicating an unlimited duration, the playback system video 12 reproduces the corresponding static image and then waits for user input from the keyboard, without calculating the difference of the time stamps of the view.

On the other hand, if the check box duration is a value indicating a limited duration, the system play the surveillance video 12 calculates the difference between the time stamps of view, included in this and the following entry-point or packet packetized elementary stream in order to determine the duration of view for the corresponding static image. The system then play the video plays the corresponding static image or before the expiration of the duration of the presentation, or to user input from the keyboard.

Fig.9 illustrates another example implementation of a data structure and method for static images the recording media of high density in accordance with the present invention. As shown, the playlist includes many elements of play associated with the respective entry points. Each element of the play includes the offset value of the length to adjust the length of the representation of the corresponding static image.

According to this embodiment, the playback system video 12 calculates the difference between the time stamps of the views included in the entry point or packetized elementary streams, as described above, and determines the initial duration of the presentation for the corresponding static image. The system then play video 12 adds the offset value length is eljnosti to the original duration of the presentation in order to determine the final length of the presentation for the corresponding static image. The data flow unit static image is reproduced in accordance with either the expiration of the finite duration of the presentation, either by user input from the keyboard.

In another embodiment of the present invention, as shown in Figure 10, the set of offset values that are consistent with the corresponding entry points are recorded and managed in the form of a list element in the playlist.

According to this embodiment, the playback system video 12 calculates the difference between the time stamps of the views included in the entry point or packetized elementary streams, as described above, and determines the initial duration for the corresponding static image. The system then play video 12 adds the offset value of the duration associated with the corresponding entry point from the list of offsets of the length to the original length of presentation to determine the final length of the representation for the corresponding static image. The data flow unit static image is reproduced in accordance with either the expiration of the finite duration of the presentation, either by user input from the keyboard.

Figure 11 schematically shows an example implementation of the device is VA recording and playback of the optical disc in accordance with the present invention. As shown, audiofilereader 9 receives and encodes data (e.g., static image data, audio data and so on). Audiofilereader 9 generates encoded data together with information about coding and attribute information flows. The multiplexer 8 multiplexes the encoded data on the basis of information about coding and information about the attributes of the stream to generate, for example, a transport stream MPEG-2. Driver source package 7 (forms of transport packets from the multiplexer 8 in the original packages in accordance with the format of audio/video data from an optical disc. As shown in figure 11, audiofilereader 9, the multiplexer 8 and shaper original packages 7 controlled by the controller 10. The controller 10 receives user input on the recording and provides control information to audiofilereader 9, the multiplexer 8 and the driver source package 7. For example, the controller 10 issues a command to audiofilereader 9 on the type of encoding for implementation, the multiplexer 8 to the transport stream to form and command the driver source package 7 on the format of the source package. The controller 10 controls the drive 3 to record the output of the shaper original packages 7 on the optical disk.

The controller 10 also generates navigation and operated the appropriate information for managing reproduction of data, recorded on the optical disk. For example, on the basis of information received through the user interface (for example, the set of commands that are stored on the disk provided with the computer system via an intranet or the Internet etc), the controller 10 controls the drive 3 to record one or more data structures Figure 1-5 and 7-10 on the optical disk.

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 user input received through the user interface (for example, using the control buttons on the recorder and playback or remote control associated with the device), the controller 10 controls the drive 3 to reproduce data from the optical disk. For example, as discussed above in relation to embodiments of the present invention, a static image or a static image can be reproduced in combination with audio data based on the navigation information. In addition, an image or group of images can be played back as a slide show or part of the slide show. As also discussed, the slide show can be synchronized, without limiting the viewing time, etc.

Reproducible source packages is prinimautsia rasformirovali original packages 4 and converted into a data stream (for example, transport stream packets of the MPEG-2 format). The demultiplexer 5 further demultiplexes the data stream in the encoded data. Audiofilereader 6 decodes the encoded data to obtain the original data, which were filed in audiofilereader 9. During playback, the controller 10 controls the operation of rasformirovali original packages 4, demultiplexer 5 and audiofilereader 6. The controller 10 receives user input on the operation of the playback and provides control information to audiofilereader 6, demultiplexer 5 and rasformirovali original packages 4. For example, the controller 10 issues a command to audiofilereader 9 on the type of decoding for the implementation team to the demultiplexer 5 traffic flow for demuxing and rasformirovali original packages 4 on the format of the source package.

Although 11 is described as a device recording and playback, it must be borne in mind that can be achieved only record or playback using parts of the device 11, which provides the function of recording or playback.

As follows from the above description, the present invention provides a recording medium with a data structure for static images, recorded on the recording medium to high density the values (for example, on the optical disk with a high recording density, such as BD-ROM). For example, the data structure allows you to display static images and possibly audio data in various ways.
