Description

1. FIELD OF THE INVENTION

The present invention relates to a recording medium with a data structure for controlling reproduction of at least static images recorded thereon, as well as methods and devices for reproducing and recording.

2. BACKGROUND

The standardization of new optical discs with a high recording density of read-only and rewritable formats, on which large volumes of high-quality video and audio data can be recorded, has been rapidly developed and production of products related to new optical discs is expected in the near future. Examples of these new optical discs are the Blu-ray disc rewritable disc (BD-RE) and the Blu-ray disc read-only format (BD-ROM).

While the standard for BD-RE has already been published, standards for high-density optical discs in read-only format, such as a Blu-ray disc in read-only format (BD-ROM), are still being developed. Therefore, an effective data structure for controlling the reproduction of still images recorded on a high-density optical disc of a read-only format such as a BD-ROM is not yet available.

3. SUMMARY OF THE INVENTION

The recording medium in accordance with the present invention includes a data structure for controlling reproduction of at least still images recorded on the recording medium.

In one embodiment of the present invention, at least one playlist is stored in the playlist area of the recording medium. A playlist includes at least one playitem and at least one sub-playitem. The playitem provides navigation information for reproducing at least one still image from the first file, and the sub-playitem provides navigation information for reproducing audio data from the second file.

In another embodiment of the present invention, the recording medium further includes a data area in which the first and second files are stored. In this embodiment, the first file includes at least one still image and associated data corresponding to the still image. In this case, the related data may include graphic data, subtitle data, etc.

In a further exemplary embodiment of the present invention, the reproducing element provides navigation information for reproducing presentation data from a first file, the presentation data including at least a static image and associated data corresponding to the static image. In this example, the presentation data can be divided into still image modules, so that each such still image module includes at least one still image and corresponding associated data.

In yet another embodiment, the still image and related data are multiplexed into the transport stream for the still image module based on the still image module. In this example, each elementary still image stream and related data can be matched in the still image module. For example, each elementary stream is a packetized elementary stream.

In another exemplary embodiment of the present invention, at least one playlist including at least one playitem and at least one sub-playitem is stored in the playlist area of the recording medium. The playitem provides navigation information for reproducing at least one static image from the first data stream, and the sub-playitem file provides navigation information for reproducing the audio stream separately from the first data stream.

5. EXAMPLES OF THE IMPLEMENTATION OF THE PRESENT INVENTION

For a more complete understanding of the present invention, the following are illustrative examples of its implementation with reference to the accompanying drawings.

High density recording media such as a high density optical disc, such as a read-only Blu-ray disc (BD-ROM), a Blu-ray rewritable disc (BD-RE), etc. in accordance with the invention may have a file or data structure for controlling the playback of video audio data, as shown in FIG. Some aspects of the data structure in accordance with the present invention shown in FIG. 1 are similar to the well-known BD-RE standard, therefore, these aspects will be considered, but not described in great detail.

As shown in FIG. 1, the root directory contains at least one BD directory. The BD directory includes shared files (not shown), the PLAYLIST directory, which stores playlist files (e.g. * .mpls), the CLIPINF directory, which stores clip information files (* .clpi), and the STREAM directory, in which clip files containing MPEG2 standard audio and video stream (* .m2ts) corresponding to clip information files.

The STREAM directory includes MPEG2 standard audio and video stream files, referred to as clip stream files or simply clip files. The audio and video stream includes source packets of video and audio data. For example, the source video packet includes a header and a transport packet. The source packet includes the number of the source packet, which is usually a sequence number serving as the address for access to the source packet. Transport packets include a packet identifier. The packet identifier indicates the sequence of transport packets to which the transport packet belongs. Each transport packet in the sequence will have the same packet identifier.

The CLIPINF directory includes a clip information file associated with each AV stream file. The clip information file indicates, among other things, the type of audio and video stream associated with it, contains sequence information, program information and synchronization information. Sequence information describes sequences based on arrival time and based on system time. For example, sequence information indicates, inter alia, the number of sequences, information about the start and end times of each sequence, the address of the first source packet in each sequence, and the packet identifier for transport packets in each sequence. A sequence of source packages in which the contents of a program is constant is called a program sequence. The program information indicates, inter alia, the number of program sequences, the start address of each program sequence, and transport packet identifier (s) in the program sequence.

Synchronization information refers to characteristic point information. One form of characteristic point information is a map of entry points. The entry point map maps the presentation time stamp (for example, based on the arrival time and / or based on the system time) and the address of the source packet (i.e., the number of the source packet). The presentation timestamp and the source packet number are associated with the entry point to the audio and video stream; that is, the presentation timestamp and the associated source packet number indicate the entry point to the audio and video stream. The package pointed to is often referred to as an entry point package.

The PLAYLIST directory includes one or more playlist files. The concept of a playlist is introduced to facilitate the editing / editing of clips for playback. A playlist file is a collection of play intervals in clips. Each play interval is called a play item. A playlist file, among other things, identifies each of the playitems forming a playlist, and each playitem, in addition, is a pair of a start point and an endpoint indicating positions on the time axis of the clip file (for example, presentation timestamps based on the time of arrival or based on system time). The playlist file may also include sub-playitems, which also provide a pair of start point and end point indicating the position on the time axis of the clip file. In other words, the playlist file identifies the playitems and sub-playitems, each playitem and sub-playitem points to a clip file or part thereof and identifies the clip information file associated with the clip file. The clip information file is used, among other things, to map playback elements to the clip file from the source packets. Playlists can also include labels indicating specific places (for example, a specific address) in the clip file.

General information files (not shown) provide general information for controlling the playback of audio and video streams recorded on an optical disc.

In addition to illustrating the data structure of the recording medium in accordance with an embodiment of the present invention, FIG. 1 shows areas of the recording medium. For example, general information files are recorded in one or more areas of general information, a playlist directory is recorded in one or more areas of a playlist directory, each playlist in a playlist directory is recorded in one or more areas of playlists on a recording medium, etc. FIG. 2 shows an example of a recording medium having the data structure of FIG. 1 stored thereon. As shown, the recording medium includes a file system information area, a database area, and an AV stream area. The database area includes a general information and playlist information file area and a clip information area. The general information and playlist information file area contains general information files recorded in the general information file area, as well as a PLAYLIST directory and playlist files recorded in the playlist information area. The clip information area contains the CLIPINFO directory and the corresponding clip information files recorded therein. The area of audio and video streams contains the audio and video streams for various sections recorded therein.

Video and audio data are usually organized in separate sections; for example, various films represented by video and audio data are organized in different sections. Moreover, a section can be organized in separate chapters, basically the same way a book is often organized in chapters.

Due to the large memory capacity of the latest high-density recording media, such as BD-ROM and BD-RE optical discs, various partitions, different versions of a section or parts of a section can be recorded from and stored on it. For example, video data corresponding to various camera angles can be recorded on a recording medium. As another example, versions of a section or parts thereof corresponding to different languages can be recorded on a recording medium. As another example, a director’s version and a theater version of a section can be recorded on a recording medium. Alternatively, versions for adults, adolescents, and children (that is, versions for parental control) can be recorded on the recording medium. Each version, camera angle, etc. correspond to a separate playback channel, and video data in these cases is called video data with multiple playback channels.

Due to the large memory capacity of the latest high-density recording media, such as BD-ROMs, static images or frames can be recorded on the recording medium and played back from it in an organized and / or interactive mode for the user, for example, in the form of slide shows. Below, a data structure for controlling the reproduction of still images for a medium with a high recording density will now be described, and also in accordance with embodiments of the present invention, methods and devices for recording and reproducing still images will be described with it.

Figure 3 shows an example of a data structure and a method for managing still images for a medium with a high recording density in accordance with the invention. A plurality of still images or frames are stored in a separate still image file on a high density recording medium such as a BD-ROM, the playlist including navigation information for controlling the playback of still images.

The navigation information of the playlist is also associated with the video or audio data of the film recorded in a specific area of the audio and video stream of the clip. A playlist indicates at which points in the video or audio data of the movie it is necessary to play back a static image. Namely, a playlist associates an audio-video stream of a clip with a static image file. The playlist may also provide a duration of display of each static image on the screen, or this information may be provided by the clip information file. Duration may be limited or unlimited.

When, based on the playback of the playlist, the playback device detects that the still image is associated with the video or audio data of the film during playback, the playback device obtains the still image from the still image file. Then, the reproducing apparatus performs a static image reproducing operation to display the static image in a limited or unlimited manner based on the duration of the presentation of the static image. When an unlimited duration is specified, a static image is displayed until input is received from the user.

As can be understood from the foregoing and subsequent disclosure, static images can be displayed as a sequential slide show, a slide show randomly selected / shuffled, or a slide show with the possibility of viewing them. A sequential slide show provides for the playback of a static image with a limited duration of playback in the order established by the playlist. This reproduction of still images can also be performed in synchronization with the reproduction of audio data. A slide show with their viewing involves the playback of static images with unlimited duration in the order specified by the playlist. The transition to the playback of the previous or subsequent static image is based on user input. A slide show selected randomly / by shuffling is a form of sequentially viewing a slide show or slide show with the possibility of viewing them, in which the order of playback of static images is random.

Figure 4 shows one example of a still image file. In this example, a static image or a group of static images form a presentation block. A presentation block may be formed, for example, from static images having a common presentation attribute. For example, in FIG. 4, static images No. 1 ~ No. k having the same presentation duration (duration No. 1) are grouped into presentation block No. 2, and static images No. k + 1 ~ No. n) having the same duration submission (duration No. 2) are grouped into a presentation block No. 2. Although the duration is given as an example of a presentation attribute, it should be borne in mind that the present invention is not limited to this example.

5 shows an example of the relationship between a playlist and at least one clip file in accordance with one embodiment of the present invention. As shown in FIG. 5, the playlist contains navigation information for controlling reproduction of the first and second presentation units (for example, the first and second presentation units shown in FIG. 4). The playitem contained in the playlist is used to control the playback of the still image stream and related data, such as graphics and subtitle streams. The sub-playitem contained in the playlist is used to control the playback of audio data corresponding to still images. As shown, the audio data is recorded in a file separate from the static image and the associated data and, therefore, are not part of the associated data. Audio data can be played synchronously or asynchronously to the corresponding static images.

The playlist also includes a playlist label, hereinafter referred to as a still image group label (SPG_mark), for each presentation block. The still image group label SPG_mark indicates the beginning of a presentation block including one or more still images.

The still image stream and related data streams (for example, graphics and subtitle streams) are packetized based on the static images into packets of a packetized elementary stream. Namely, each packet of the packetized elementary stream in the static image stream includes one static image. Packets of the packetized elementary stream are encoded into transport packets of the MPEG2 standard and then multiplexed into the transport stream. This will be discussed in more detail with reference to the examples presented in FIGS. 6 and 7.

The navigation information for the associated reproduction of the static image, as well as the graphic and subtitle data corresponding to the static image, is recorded in packets of the packetized elementary stream of the static image and the corresponding graphic data and subtitle data. As shown in FIG. 5, a unique image identifier corresponding to the number of the static image may be included in the packetized packetized elementary stream packet of the static image and packets of the packetized elementary stream of the respective graphics and subtitles.

The reproducing apparatus can efficiently control the reproduction of still images of presentation units grouped using still group labels SPG_marks contained in the playlist. In addition, the playback device performs the associated playback of the static image and graphics and subtitles corresponding to the static image by determining a unique image identifier of the static image. During playback of still images and related data, the playback device further reproduces the audio stream indicated by the sub-playitem.

Figures 6 and 7 show an example of a data structure and a method for managing still images of a high density recording medium of the BD-ROM type, similar to that described above with reference to Figure 5. The most noticeable difference between the two is that the example of FIG. 6 and FIG. 7 does not contain presentation blocks.

As shown in FIG. 6, a still image stream and related data streams (eg, graphics and subtitle streams) are packetized into packets of a packetized elementary stream based on still images. Namely, each packet of the packetized elementary stream in the static image stream includes one static image, and the corresponding packets of the packetized elementary stream of related data include related data corresponding to the static image (for example, for reproduction synchronously with the corresponding static image). A static image, together with related data to be reproduced synchronously with it, is grouped into a static image module. Based on the static image modules, the static image stream and related data streams are multiplexed into the MPEG2 transport stream standard image file.

6 further shows a clip information file corresponding to a still image file. The clip information file includes an entry point map (EP_MAP). Individual entry points No. 1 ~ No. k in the map of entry points contain relevant navigation information for accessing the recording position of the header of the corresponding static image module. For example, the navigation information includes information about the starting position of the entry point for a given source packet number (SPN_EP_Start) indicating the starting position of the recording of the corresponding still image module.

Fig. 7 is a playlist for controlling reproduction of a still image file discussed above with reference to Fig. 6. As shown, the playitem (Playltem) in the playlist contains information about the start image (IN_picture) and the end image information (OUT_picture) corresponding to the start position and end position of the still images in the still image file for reproducing the SubPlayltem) in the playlist contains information about the start time of the playback sub-playitem (SubPlayltem_IN_time) and information about the end time of the sub playback lementa reproduction (SubPlayltem_OUT_time) for separate audio file to be reproduced in connection with the still picture file. Audio data can be played synchronously or asynchronously with the corresponding still images.

The playlist also contains a playlist label, hereinafter referred to as a static label, indicating each static image. Information about the duration of the presentation for the static image and related data included in the static image module can be recorded in the static label corresponding to the static image module. Alternatively or additionally, presentation duration information may be contained in a playitem.

Static labels are especially useful when skipping between images during a slide show. Additionally, you may notice that the static image file or parts thereof can be simultaneously associated with several playlists having different presentation durations.

On Fig shows the physical location of the transport stream of the MPEG2 standard, for example, on an optical disk. As shown, each part of the MPEG2 transport stream corresponding to the still image module is recorded in agreement with a physical recording unit, for example, an element of an error correction code block (ECC Block) or an optical disc sector element. For example, if the recording size of the transport stream corresponding to the second block of still images is such that it does not fill the physical recording unit, then the blank area is filled with null data.

Figure 9 is a schematic diagram of a partial structure of an optical disc device to which the present invention is applied. As shown, the optical disc apparatus includes an optical head 111 for reproducing data from an optical disc. The playback system of the video disc 112 controls the operation of the optical head 111 to reproduce and demodulates the data reproduced by the optical head 111. The playback system of the video disc 112 generates an audio-video stream, which can also be supplied to a digital-to-analog converter 13 to generate an audio-video stream in analog form.

The video playback system 112 controls the optical head 111 and demodulates reproducible data based on user input received through the user interface, as well as navigation and control information recorded on the optical disc in accordance with the present invention. For example, to play back a still image file, the video disc playback system 112, as described above, refers to still image labels contained in the playlist, as well as to the map of entry points contained in the clip information file. Namely, the playback system of the video disc 112 reads a static image, graphic data and subtitle data of each static image module in accordance with the order of entry points (EP No. 1, No. 2, ...) recorded in the map of the entry points. Then, the playback system of the video disc 112 performs a sequence of operations to play slide shows that can be played for a fixed time in accordance with the information on the duration of the presentation contained in the static marks, or reproduced with skipped blocks for a block of static images in accordance with each of the static image labels according to input from the user's keyboard.

As shown in FIG. 10, a video disc playback system 112 may include a switch 120, a track buffer 121, a transport stream demultiplexer 122, a video buffer 123, a graphics buffer 124, a subtitle buffer 125, an audio buffer 126, a video decoder 127, a graphics decoder 128, a subtitle decoder 129, an audio decoder 130, a program clock group counter (PCR) 131, and a microcomputer 132.

The microcomputer 132 controls the operation of the switch 120 in accordance with the input from the user keyboard or information about the duration of the presentation, so that a static image (V), graphic data (G) and subtitle data (ST) are selectively fed to the track buffer 121. The transport stream demultiplexer 122 accesses to the packet identifier of the data stream temporarily stored in the track buffer, and distributes the static image data, graphic data and subtitle data, respectively, to video buffer 123, graph buffer ici 124 and subtitle buffer 125.

The video decoder 127 decodes the static image data, the graphics decoder 128 decodes the graphic data, and the subtitle decoder 129 decodes the subtitle data. As a result, a single static image and associated graphics and subtitle data are reproduced.

Similarly, the microcomputer 132 controls the operation of the switch 120 and selectively feeds the audio data (A) read from the optical disc to the buffer of the track 121. The demultiplexer of the transport stream 122 refers to the packet identifier of the audio data stream temporarily stored in the track buffer, so that the audio data is extracted and fed to audio buffer 126.

The audio decoder 130 decodes and provides decoded audio data. At this stage, presentation time stamp information allocated by the transport stream 122 demultiplexer is supplied to the audio decoder 130. In addition, the program clock group counter 131 counts the program clock group information allocated by the transport stream 122 demultiplexer, and the program clock counting result is supplied to the audio decoder 130. Since the use of presentation timestamps and program clock groups is well known in the art, their inclusion in data recorded on an optical disc it is not described.

The audio decoder 130 reproduces the audio data when the result of counting the software clock groups matches the value of the presentation time stamp. The result of counting the software clock groups and the value of the presentation timestamp are provided only to the audio decoder 130, whereby the playback time of the audio data is adjusted.

Accordingly, the device for an optical disk, using a switch 120, a track buffer 121, and a transport stream demultiplexer 122, can normally perform slide show operations by reproducing a still image file and an audio file separately, but in connection with one another on a Blu-ray disc format only reading.

Figure 11 shows in detail another example implementation of a system for playing a video disc 112. This example is similar to the example in Figure 10, except that it additionally includes an adder of presentation timestamps 133 with corresponding connections to it. As discussed above, the microcomputer 132 accesses the user input from the keyboard or information about the duration of the presentation and thus controls the operation of the buffer of the track 121 and the switch 120. The same information is used to control the adder of the timestamps of the presentation 133.

The presentation time stamp adder 133 refers to the presentation time stamp of the audio data temporarily stored in the track buffer, and further writes the presentation pseudo-time stamp identical to the presentation time stamp of the audio data to packets of the packetized elementary stream of still image data, image data, and subtitle data.

The audio presentation time stamp allocated by the transport stream demultiplexer 122 is transmitted to the audio decoder 130, and the program clock groups information extracted by the specified transport stream demultiplexer is counted by the indicated program clock group counter 131. The result of the calculation of the program clock groups is supplied to the audio decoder 130, and when the result of the calculation of the program clock groups coincides with the presentation time stamp, the audio decoder 130 reproduces the audio data.

The pseudo timestamp allocated by the transport stream demultiplexer 122 and the program clock counting result are also distributed to the video decoder 127, the graphics decoder 128, and the subtitle decoder 129. When the program clock counting result coincides with the presentation time pseudo-counting, static image data and graphic data are reproduced. and subtitle data.

Thus, the device for the optical disk, sharing the switch 120, the buffer of the track 121 and the demultiplexer of the transport stream 122, can normally perform slide show operations by playing back a still image file and an audio file, separately, but in connection with one another recorded on a Blu-ray read-only format disk.

12 is a schematic diagram of an example optical disc recording and reproducing apparatus in accordance with the present invention. As shown, the AV encoder 9 receives and encodes data (e.g., static image data, audio data, etc.). The audio-video encoder 9 provides encoded data along with encoding information and stream attribute information. A multiplexer 8 multiplexes the encoded data based on coding information and stream attribute information to generate, for example, an MPEG-2 transport stream. The source packetizer 7 generates transport packets from the multiplexer 8 into the source packets in accordance with the audio-video format of the optical disk. As shown in Fig. 8, the operation of the AV video encoder 9, the multiplexer 8 and the source packetizer 7 is controlled by the controller 10. The controller 10 receives input from the user to record and provides control information to the AV video encoder 9, the multiplexer 8 and the source packetizer 7. For example, the controller 10 issues a command to the AV encoder 9 for the type of encoding to implement, issues a command to multiplexer 8 to generate a transport stream, and issues a command to the source packetizer 7 for the format of the source packet but. The controller 10 further controls the drive 3 in order to record the output from the source driver 7 to the optical disk.

The controller 10 also generates navigation and control information to control the playback of data recorded on the optical disc. For example, based on information obtained through the user interface (for example, a set of instructions stored on a disk provided by a computer system via an intranet or the Internet, etc.), the controller 10 controls the drive 3 to record one or more data structures in accordance with Figure 1-8 on the optical disk.

During playback, the controller 10 controls the drive 3 to reproduce this data structure. Based on the information contained in it, as well as user input received through the user interface (for example, using the control buttons on the recording and playback device or the remote control device associated with this device), the controller 10 controls the drive 3 to reproduce data from the optical drive. For example, as discussed above in connection with embodiments of the present invention, a still image or still images may be reproduced in connection with audio data based on navigation information. In addition, an image or group of images may be reproduced as a slide show or part thereof. As also discussed above, the slide show can be synchronized, viewable, etc.

Playable source packets are received by the source packet resolver 4 and converted into a data stream (for example, an MPEG-2 transport packet stream). Demultiplexer 5 demultiplexes the data stream into encoded data. The audio-video decoder 6 decodes the encoded data in order to generate the source data that was supplied to the audio-video encoder 9. During playback, the controller 10 controls the operation of the source packetizer 4, demultiplexer 5 and the audio-video decoder 6. The controller 10 receives the user input for playback and provides control information to the audio-video decoder 6, a demultiplexer 5 and a source packetizer 4. For example, the controller 10 instructs the AV decoder 9 on the type of decoding for Lenia, instructs the demultiplexer 5 on the transport stream demultiplexing and command source depacketizer 4 on the source packet format.

While FIG. 12 has been described as a recording and reproducing apparatus, it should be borne in mind that a recording-only or reproducing-only apparatus can be provided in which those parts of the apparatus of FIG. 12 which provide recording or reproducing functions are used.

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

The still image management method for the high density recording medium in accordance with the present invention enables various still image management operations and can efficiently reproduce still images in connection with the corresponding subtitle data or graphic images.

As is apparent from the above description, the present invention provides methods and apparatuses for recording a data structure on a high density recording medium in order to control still images recorded on the recording medium.

In addition, the above description describes methods and devices for reproducing still images recorded on a high density recording medium based on a data structure also recorded on a high density recording medium for controlling reproduction of still images.

Although the invention has been disclosed in a limited number of embodiments, those skilled in the art will recognize from this description that numerous modifications and changes are possible. For example, although the description relates to a read-only Blu-ray ROM optical disc, the present invention is not limited to this standard optical disc or to optical discs per se. It is intended that all such modifications and changes fall within the spirit and scope of the present invention.
