Embodiments of the inventions

To ensure full understanding of the invention will hereinafter be described exemplary embodiments of its implementation with reference to the accompanying drawings.

According to the present invention in one page can be enabled many objects presentation graphic data. For example, as shown in figure 1, on one page can be displayed two such sites. The object of the presentation graphic data recorded on the BD-ROM can be written in the form of data, text subtitles, subtitle data in the binary display (PAOs, BMP), data, graphics, etc. Each object forms a region presentation image data.

Data text subtitle subtitle data PAOs or data graficas the CSO image, corresponding to each of the objects is recorded as the segment data object (SDO, ODS). At least one segment of the data object (SDO) can be arranged together with one segment of the composition of the page (SCS, PCS), one segment of the color determination on the reference table (SOTS, CDS) and one segment of the group "the late show" (END, END) in a hierarchical fashion, as shown in figure 2. Each of these segments will be described in detail below.

Each segment in this hierarchical structure is first arranged in the package packetized elementary stream (PES), and then organized into transport packets (TP) MPEG before being recorded on the BD-ROM. In particular, each segment (e.g., SCS, SOTS, LMS etc) seems to be one PES packet. Unique ID (ID, ID) packet corresponding to the data type of the segment data object (SDO)recorded in the corresponding PES packet. For example, if the segment data object represents a subtitle data PVO, the unique ID of the package PID_bmp, is recorded in the corresponding PES packet. Similarly, if the segment data object is a data text subtitle, the unique ID of the package PID_text, is recorded in the corresponding PES packet. Therefore, the playback device optical drive BD-ROM identifies the data type of each PES packet by analyzing the ID of the package is, recorded in the PES packet. The presentation graphic data and the main audio/video streams are multiplexed in one transport stream (TS) and saved as a single file.

Figure 3 illustrates a sample implementation of a data structure for segment composition of the page, recorded on a medium with a high recording density according to the present invention. As shown, the segment composition of the page (SCS) contains information about the type of segment, the segment length, the time limit (timeout) page, the version number of pages and the page state. The segment type is information indicating that this segment is a segment of the composition of the page (SCS). Segment length indicates the length of the segment. The timeout page is information indicating when to delete the buffered data of the relevant page from the buffer of the playback device. The version number of the page indicates the version of the SCS. The status page shows the status of the SCS (e.g., update only SOTS related to LMS).

Segment composition of the page (SCS) also contains ID information table color (Stid, CLUT_id) and the indicator for the number of inputs of the object. ID RTCs shows the ID of the matching circuit and SOTS with the same ID RTCs, associated with SCS. For each input object (i.e., for example, each region presentation grafy the definition data) SCS also contains the object ID, flag trim object (objectopen, is_object_cropping) and the address of the object horizontally/vertically. Object ID specifies the identifier of the object and binds each LMS with the ID of the object (which is discussed in detail below), with SCS. Thus, LMS and SOTS can be connected to each other by the ID of the matching circuit and the object ID contained in the SCS. The address of the object horizontal/vertical lines show the position of the object on the presentation page (such as shown in figure 1).

If the flag trim object (objectopen) is set to '1', the information flag trim object may include data trimming object vertically/horizontally and trimming data object width/height. Data trimming object horizontally/vertically and data trimming object width/length are recorded for a partial display of the object image. In particular, information about cutting the object along the horizontal/vertical line indicates the position of the crop rectangle (square crop), having secured the width/length of the trim. Will be shown only the portion of the object that lies within the crop rectangle.

Figure 4 illustrates a sample data structure for segment definition color information table recorded on the medium with a high recording density according to the present image the structure. As shown in figure 4, the segment definition color reference table (SOC) contains the segment type, segment length and ID reference table color (SCID). The segment type identifies the segment as a SOCIAL, segment length indicates the length of the SOC. Information ID RTCs specifies the family RTCs belongs to SOTS. As will be described in detail below, the SOC determination of the same color. Family RTCs provides a color palette from which you select the color.

The segment definition color reference table may also contain information regarding the ID of the entry in the reference table of the color, the brightness value (Y-value), value, chroma red (Cr-value), the value of the color blue (Cd value) and the value of transparency (T-value). Accordingly, when the connection object by SCS these values control such attributes color of the displayed object, such as brightness, chroma (Cr and Cb) and transparency. ID of the input matching circuit identifies the entrance of this SOC family matching circuit (identified by the ID RTCs), belongs to this SOC.

Figure 5 illustrates a sample data structure for the data segment of the object, recorded on a medium with a high recording density according to the present invention. As shown, the segment data object (SDO) contains the type of the segment, the segment length is a and the type of the object. The segment type indicates the type of this segment as LMS. Segment length indicates the length of the LMS. The object type identifies whether the segment object data segment text subtitle segment subtitle PAOs, graphic element PBO, etc. Specifically, the object type identifies the type of data represented by this segment of the data object.

If the object type indicates that the data segment of the object is a segment of text subtitle data in the text object includes the object ID and the number of text objects. The object ID that identifies an object associated with the given segment of text subtitles. The number of text objects specifies the number of text objects in a given segment of text subtitles. For each text object data type object include field properties of the text field properties of the font and the length indicator text. Field properties text and font will be described below with reference to Fig.6 and 7. Indicator text length specifies the length of the text that forms the text object text subtitles, and attached character code that indicates each character forming this text object.

As shown in Fig.6, the field text properties contain information about the style of the text, as the text alignment (e.g. left, right, center, width and d), text (for example, overline, underline, along the lines, flickering, no etc), indent text (for example, the indent size), modification of the text (for example, uppercase, upper case, lower case, no and the like), the letter spacing, spacing, spacing between words and text width.

As shown in Fig.7, margins, font properties contain information about the style of the font as font, font-family, font-size, font variation and density of the font.

If the object type in the LMS indicates that the data segment object represents a subtitle data PVO, these data include the object ID, object width, object height, group code, etc. as shown in Fig. The object ID that identifies an object that is associated with this segment of the subtitle PAOs. The width of the object specifies the width of the object, and the object's height specifies the height of the object. Group code displays the data bit-by-bit display format group encoding.

Figure 9 shows a variant implementation of the data structure for segment group "the late show", recorded on the medium with a high recording density according to the present invention. As shown, the segment of the group "the late show" (END) includes the segment type reserved part and the length of the segment. The segment type indicates that this segment are the two which is the segment of the group "the end of the display. Reserved part reserved for future use, and segment length indicates the length of the segment.

Figure 10 presents a structural diagram of a variant of execution of the device for recording and reproducing optical disks. As shown in the drawing, audio/video (AV) encoder 9 receives and encodes data (e.g., data, text subtitles, and so on). The AV encoder 9 generates encoded data together with information coding and information thread attributes. The multiplexer 8 multiplexes the encoded data on the basis of information coding and information thread attributes to create, for example, a transport stream MPEG-2. Unit 7 forming the source packages pattisue transport packets from the multiplexer 8 in the original packages in accordance with the audio/video format in the optical disk. As shown in figure 10, the operation of the AV encoder 9, the multiplexer 8 and the block 7 to generate the initial packets controlled by the controller 10. The controller 10 receives user input for a write operation, and transmits the control information in the AV encoder, the multiplexer 8 and the block 7 the formation of the original packages. For example, the controller 10 instructs the AV encoder 9 what type of encoding should be performed, the multiplexer 8 about how the transport stream should generate, and the block 7 to generate the initial packet of the format is similar packages. The controller 10 also instructs the drive 3 to record the output of the unit 7 forming the source packages on the optical disk.

On the basis of information received through the user interface (for example, the set of commands that are saved on the disk provided by the computer system on the internal network or the Internet, and so on), the controller 10 instructs the drive 3 to record one or more data structures, shown in figure 2-9 and 13-15 (described below), on the optical disk.

During playback, the controller 10 instructs the drive 3 to reproduce the data structure. On the basis of the information contained therein, as well as user input received through the user interface (for example, the control buttons on the device for recording and playback or remote control associated with the device), the controller 10 instructs the drive 3 to reproduce data from the optical disk.

Reproduced source packages are extracted block 4 disassembly packages and converted into a data stream (for example, the transport stream packet MPEG-2). The demultiplexer 5 further demultiplexes the data stream into encoded data. The AV decoder 6 decodes the coded data to obtain the original data that were submitted to the AV encoder 9. During playback, the controller 10 controls works the th block 4 disassembly packages the demultiplexer 5 and the AV decoder 6. The controller 10 receives user input on the playback operation, and transmits the control information in the AV decoder 6, the demultiplexer 5 and block 4 disassembly packages. For example, the controller 10 instructs the AV decoder 6 which type of decoding to perform, the demultiplexer 5, what traffic should be demultiplex, and tells the parser performs 4 packet format source packages.

Although figure 10 has been described a device for recording and playback, it is clear that it is possible to provide the device only for recording or playback only using those parts of figure 10, which provide the function of recording or playback.

If the user of the device for optical disk drive requests a data reproduction of text subtitle presentation of image data recorded on the BD-ROM 1, the controller 10 identifies the data text subtitles by checking the ID packet of the PES packet corresponding to the segment data object (SDO) data text subtitles, as described with reference to figure 2, or by checking the type of the object contained in the segment data object (SDO) data text subtitles, as described with reference to figure 5.

Then, the controller 10 represents data from a text subtitle in different is cnyh styles according to the information about the style of the text, included in the property field of the text, and information about the style of the font is included in the property fields of the font, which both contained in the segment data object (SDO) data text subtitles. As shown in figure 11, two objects (object 1 graphics, and object 2 data text subtitles) can be presented on one page at a time. The data object text subtitles (object 2) can be represented in different text styles and font, as shown at 11 and 12.

In another embodiment of the present invention the object type field text properties and fields of font properties that were included in the segment data object (SDO)are included in the segment composition of the page (SCS), as shown in Fig. In this case, the controller device for the optical disc is a data object text subtitles in different styles according to the type information of the object, fields, properties of text fields and properties of a font included in the segment composition of the page.

In yet another embodiment of the present invention, the information about the style of the text and information about the style of the font is stored in the segment data object (SDO) data text subtitles, but the field properties text boxes and font properties not classified explicitly. Instead, information about the style of the text and the font style is written follower is on after the preset identification code (for example, exchange code alphabet=0xffff). In this case, the controller 10 of the device for optical disc is a data object text subtitles in different text styles and font in accordance with information about the style of the text and the font style that follows the specified identification code.

In yet another embodiment of the present invention, the data segment of the text object (text-LMS, Text-ODS) recorded in parallel with the segment composition of the page (SCS), the segment definition color reference table (SOC) and other type of segment data object (SDO) (for example, the data segment object PAOs or segment data object graphic images). In this embodiment, information about the type of the segment included in the data segment of the text object (text-SRE), has a unique value indicating that this segment is a data segment of the text object. Other fields in the text-LMS correspond to the fields described in connection with figure 5.

Another type of segment data object (SDO) (for example, the data segment PBO (PBO-LMS, BMP-ODS) is shown in Fig. This LMS contains information about the type of segment that has a unique value to indicate that this segment is the data segment object PBO (PBO-LMS). Other fields in DLS correspond to the fields described in connection with Fig.

The controller 10 of the device for the protected area the economic disks made with the possibility of selective playback of data segments of a text object by reference to the information on the segment type and display text objects in different text styles and the font in accordance with the fields of the properties of text fields and properties of the font that is included in them.

FIELD: optical data carriers.

SUBSTANCE: data carrier has data area. The latter has multiple zones, in which code blocks with error corrections are formed and sectors remaining as a result of sliding replacement at the end of zone, number of which is less than necessary for forming of one code block with error corrections. Said sectors are not used for recording one code block with error corrections and are skipped, and said code block with error corrections is formed at the beginning of next zone after skipping sectors of zone noted above. Carrier has additional free space, necessary for skipping sectors remaining at the end of zone during sliding replacement process.

EFFECT: higher efficiency.

FIELD: optical data carriers.

SUBSTANCE: method includes following stages: forming of a group of multiple zones on disk, while a group includes data area of user, including code block with correction of mistakes, distribution of primary, free space for the group. Additional free space is distributed with possible exclusion of discontinuousness of code block with correction of mistakes contained in user data area, at the limit between zones and distribution of it at two zones. Such distribution may be realized by skipping sectors at the end of zone, of their number is less than needed for forming code block with correction of mistakes with correction of primary position of code block with correction of mistakes at limit between zones.

EFFECT: higher efficiency.
