The method of transmitting information using a data carrier, the data carrier and a device for reproducing information from such media
(57) Abstract:The invention relates to a system for transmitting audio and/or video information, such as encoded audio or encoded video. The essence of the invention: channel subcode read-write text information is coded signal recorded about audio and/or video. This information is divided into packets. Packets containing information of different categories, alternate. After reading information from the disk, the packets of the selected category are separated from the read information. This system for the transmission of additional information allows you to use your own category of service for each of a number of different languages, so that the user can choose the language with which he is most familiar. In addition, the information menu that contains the string encoded text menu and command codes written in the channel subcode read-write for interactive control of the read audio and/or video data or control other connected devices. 3 C and 41 C. p. F.-ly, 1 tab., 14 Il. The invention relates to the accumulation of information, in particular to a method for transmitting information using a data medium on which to record the information channel, and after the reading of recorded information psycho-informational channel is separated. The invention relates to an information carrier and the device used for this method.There is a method of transmitting information using a data carrier, which consists in adding to the basic information sub-code data, the read and write data, and then reformatting (1).It is also known playback device encoded for playing digital audio disk, which podlodowych channels of the recording-playback recorded additional text information that can be displayed (2). The device includes a demodulator, a processing unit, a processor, a signal Converter, one or more blocks playback.The objective of the invention is to simplify the interaction with a device for playing media.In accordance with the invention this objective is achieved by using method, characterized in that the channel subinformation burn bags in a variety of categories of information interleaved with packets of different categories, and then select the information packets of the selected category is ket for information of different categories can be used for each of the different languages your category package so the user can choose the language of the text information to be displayed on the screen. Because packets are interleaved, the average time delay, after which the information of the selected category is available, a little. In particular, when information is transmitted using a sub-code channel read-write the encoded audio signal, the delay time is very small due to the large number (75) of packets per second that are transferable. This high speed data has the advantage that the same information can be repeated several times without appreciable reduction of delay time, so that just increases the transmission reliability without any appreciable loss.An example implementation of the method is characterized by the fact that in addition to code main category packages contain code category indicating the subcategory to which they belong packets of information, and the fact that the code combination is the main category code and category are identified in the packages, and the packages in which the identified combination code main categories and category corresponds to a given main and category, separate. The use of category information allows you to send different types of info a simple sample of various types of information such as song titles, artist name and so on.Another example of the method differs in that the specified code main category defines a lock function that locks the pre-selected sampling main categories. Application blocking the main categories of information in relation to pre-selected main category favorably to those that are not language-specific information should be used only channel main categories, all of this in the case when the specified channel is specified (block) main categories.Another example of the method differs in that the specified code category defines a lock function that locks the pre-selected sample category. This gives that you can send important messages regardless of the selected category.Another example of the method differs in that the packets contain encoded text strings and additional control codes. This example allows you to work so that reading of information can simply be managed by the information recorded on the packages. Very attractive managing code is a text position code indicating the position to the th.Another example of the method differs in that the control codes in the packets containing the encoded text, include text positional codes for at least two display devices, in which the number of rows that can be displayed is different. The use of two different text positional codes that are directed to one and the same row of the encoded text, allows you to apply various display devices, it does not require that the same information encoded string of text to be transmitted for each display device.The method allows you to display the same text on the 21st row of the display cathode ray tube and a two-line liquid-crystal display. In the case of use of the device playback coded video data, the text may appear on the TV screen, which is typically used in combination with digital video. The same text can also be displayed on the two-line display, consisting of a playback device encoded recording or video playback coded record, when there is no television equipment.Another example of the method differs in that a variety of information packets in one category to form a group, and start each group marked the starting code, and after changing the selected category office packages with information of the newly selected category is delayed until the selection of the starting code of the group of packets with the newly selected category of information. This allows you to get a single group of text strings, which are always presented consistently from a specified position on the screen forward, for example, from the top to the bottom.Another example of the method differs in that the coded text line menu and record the appropriate codes in the packets and the fact that prompt and corresponding command codes separated packets is recorded in the memory menu, so the shining code serves the command code, stored in the memory and corresponding to the selected line of text menu, in one of the devices. This device has the advantage that can be realized by simple control of interaction between the playback device.Another example of the method is characterized by the fact that the package contains the index code indicating the address, which must be remembered by the memory line memory encoded menu and corresponding command codes. This example has the advantage that the load memory to remember information menu is simple, because the menu is fully communicated with other information.Another example implementation of the invention differs in that the storage medium is a digital disc or digital video disc TABLE of CONTENTS recorded on the introductory track, previous chief information tracks in which the recorded main information, and the fact that the introductory track recorded by the team of the Transition and the channel sub-code recording-reading in combination with functional control codes.Hereinafter the invention is described in more detail using an example.On formed from bits of the signal sub-code read-write single block of standard digital signal; in Fig. 4 the sequence number of synthesis packages in different categories of information; Fig. 5-12 example of the format of the data packet for use in the method according to the invention; Fig. 13 is an example of the device used in the method according to the invention; Fig. 14 diagram of an information track of the information carrier in accordance with the invention.In Fig. 1 shows the flow of digital data recorded on the CD-ROM, or audio channel digital video disc. Each FRAME consists of 588 bits of write data, each FRAME has a header sync pulse FS frame with a specific allocation of bits. For a sync pulse FS frame followed by the bits of RB limitations of the communication channel in the form of three bits. Then 0-32-th data bits DB, each of which has fourteen bits, and then can register three-bit restrictive bits RB communication channel. Zero bits of these data bits DB are referred to as signal subcode and are used to control playback of the disc and display the appropriate information or similar data. The first is the twelfth and 17-18-th data bits DB are used for audio data in the main channel. The rest 13-16 th and 29-32-th data bits are used for parity data to the in which the converted 8-bit data by converting 8-14 when recording.In Fig. 2 shows the state of one BLOCK (98 frames), in which 98 frames arranged in series and in parallel, each of the data bits represented by 8 bits, and restrictive bits DC data channel is excluded. The signals of the sub-code read-write in the Q-th and I-th frames form of synchronization patterns that are predetermined bit structures. For the Q-channel entered CRC codes for error detection in the last 16 FRAMES from among the 98 FRAMES.The signal of the P-channel is a check box for indicating musical program and pause and has a lower level throughout the music program and a higher level throughout pause in the lead section has pulses with a period of 2 Hz. You can select and play the specified music program by identifying and counting the signal in the R-channel. Q-channel allows more sophisticated control of this type. For example, when the information of the Q-channel included in the microcomputer available device disc, you can quickly jump from one music program to another during playback music program; therefore, appropriate from music programs can get Proizvodstvo information and commands for the mutual control of reading of the recorded information. The format in which these data are transmitted will be described in detail later.98 bits of the Q-channel first two bits are used for the synchronization circuitry, the following four bits control bits, these 72 bits data bits and, finally, adds a CRC code to detect errors. Code TNR track number and the index code X is included in the 72 bits representing data bits. Code of the track number can vary from 00 to 99, and the index code can also be changed from 00 to 99. In addition, the data in the Q-channel contains a code indicating the time representing the duration of musical programs and pauses, and the code indicating the time, representing the absolute duration, which continuously varies from the beginning to the end on the very edge of the square program CD-ROM. These codes indicate the time contain code that indicates the minute, second and FRAME, and each consists of two digits. One second is divided into 75 FRAMES. For obrazenia to the CD-ROM, for example, to digital data at a shorter unit basis, than the music, use the code indicating the time in relation to the above absolute duration.Bits are read and write each BLOCK contains a package of 96 characters from each Domu package code assigned main category code and category, indicate the category to which belongs the information in the package. Packages of different categories alternate. The information recorded in the packets, may be a test or visual information displayed on the display, or command codes for controlling the reading of the information.In Fig. 4 shows a sequence of alternating packages of different categories. Packages of different categories designated positions respectively 1A, 1b and 1c. Packets of the same main category form the main channel. Packets of the same category in the main channel to form a subchannel.The choice of the main channel can be determined by the language of the text information to be displayed. The use of channel subinformation can be selected depending on the categories of subinformation type of album, track title, track list, artist, etc.The use of channels of different categories allows you to select the language and categories of subinformation to be displayed during playback of a disc.In Fig. 5-8 shows the packet formats 0, 1, 2, and 3, respectively, suitable for a transmission line of the encoded text. The symbol 0 of each package is used for oboznachaemogo string 40 text groups. Bits of symbol 1 and bit 5 symbol 5 pack 0 and bit 4 of symbol 4 package 3 is used to transfer eight bits (sic 7 sic 0) that indicates the category of subinformation. Bits (mic 5 mic 0) symbols 1 of the package 1 are used to indicate the main categories. In this approach, 64 different main categories and 256 different sub-categories can be selected. Bit 5 symbol 4 each package is used for synchronization of the package. Characters 2, 3 and 20-33 each package are used to check the error and correct the error. Characters 6-19 package 0, 6-18 characters and bits 5 and 4 characters 19 characters 6-18 package 2 and the characters 6-18 package 3 are used to transfer 40 bits, each of which indicates the encoded group test, for example, alphanumeric character. Bits 4-0 (L4-L0) character, 4, packet 0, cause the first text position code indicating the vertical position at which the passed string of text should appear on the display when the first tank display, for example, the display cathode ray tube with capacity display 21 lines of text. Bits LSD 1 and LSD 0 character 4 of the package 1 cause the second text position code indicating the vertical position, at which the encoded text string should be displayed on the display of the CE line. The use of two different codes, the text prescribed for the same line of text, allows for the display of various types: in the case of a 21-line display and two-line display. Display with 21 strings, made in the form of a television screen, usually available when the video information is transmitted with the encoded video. However, in the absence of 21-line display information or part thereof may be displayed on the two-line display. You can also display a variety of information on two different displays, for example, 2-line display can be used to display textual information to specify the function of the so-called key variable function, whereas 21-line display is used to display other text information. When the two different display used in this way, it may seem lowercase codes provisions in the text of the L4-L0 00000 and LCD 1 LCD 0 00 encoded text string of the package should not be displayed on a 21-row display or respectively 2-row display.Bits 3-0 of symbol 19 package 1, the symbol 19 package 2 and the symbol 19 package 3 is used to transfer the two-byte index code to indicate the position of saponi clucht tool display to on or off. Other bits of packets 0-3 are used for other data to display the encoded text, such as color detection, determining the size of the move, determine a display mode only for text, text in combination with the previous video etc.In Fig. 9-12 shows an example of a format that is suitable for transmission of command IDs. Bits used to indicate the main channel and subchannel, check the error and correction, synchronization and switching on and off of the display are the same as in the format shown in Fig. 5. The symbols 0 in bits 0-2, used to group code package 0-3 are used to specify the type of format. Using the 4-bit code DAT-DAT in bits 4-0 character pack 4 0, you can specify that the package contains command codes. The bits used for the transmission of command codes are the same as for transferring groups of the encoded text in the format shown in Fig. 6. For each command code is sent to a group of 7 bytes, and two bytes are used for double-byte index code indicating the position stored in the memory menu, the other five bytes are used to specify the command.The use of packages for before the tion, using the information menu, transferred to the playback device using a package written in podkapova channel read-write.In Fig. 13 shows a device for reproducing information recorded on the storage media. This device has a display for displaying text information written in the packet, and means for dialog control reading using the information menu, written in packages. On the media 3 information recorded signal, which contains the coded signal of the sub-code read-write, which bits are recorded in the formats described above. Such a storage medium may be a digital video disc on which the recorded FM-modulated video signal and the encoded signal. The disk medium rotates by means of a drive motor 4. The reading head 5 can be moved in the radial direction by using a system of radial positioning, for example of the engine 6 and the lead screw 7 under the control of the conventional circuit 8 controls to find the address information on the storage media. Read signal is supplied to the circuit 9, which separates the coded signal and the FM-modulated video signal.video, for example, in the PAL or NTSC. Diagram 10 video processing includes means for separating codes number of images transmitted together with the video data. Codes non image is fed to the circuit 8 controls. The encoded signal is fed to the CPU 11 of the encoded signal for converting the encoded signal into a sound signal and separating podlodowych signals read on the record. Podlodowy signals read record is fed to the processing circuit podmiotowego signal, which may consist of a microcomputer 12 of a known type. The microcomputer is loaded by the program to determine whether the received packet format described in Fig. 9-13, using symbols packages. Then read the key codes and category codes in the packets and compare with codes representing the selected key codes and category codes. Packets whose code identified categories corresponds to the selected category, separate and argue. Group of the encoded text and the signals for controlling the display of the selected packet is fed to the Converter circuit 13 of the usual type for converting groups kotirovalnogo text in the video signals to display a line of text in the status line on the display screen, the decree of the processing of the video signal, also served on the schema 13 conversion.Depending on the control signals received from the microcomputer 12, a conversion chart 13 will cause the combined video image represented by the video signal, and text represented by the accepted groups of the encoded text; display only video, display only text information.As described above, the packets of the different main categories of information can mainly be used for transmitting test information in different languages. Packages of various categories of subinformation can be used for various types of information, for example, submenu, albums, titles, tracks, indexes, list of names of tracks or text lyrics. In this approach, the user can choose the type of text information to be displayed, and the language in which to display text information.Preferably one code main category is reserved to indicate blocking the main category and one code category is reserved for specifying a blocking category. The information in the packet blocking code main categories and blocking code category seggie and category. The information in the packet blocking code main category code and category non code category blocking, only served on the translation scheme 13, if the code subcategorie corresponds to the chosen category of subinformation.The information in the packet ID of the main categories that are not code the main category with blocking only served on the mapping, if the code is the main category corresponds to the selected main categories of information. The use of categories of information with blocking favorably when should display information in the form of text, regardless of the language, in this case, it is sufficient to record language-independent information only in the main channel blocking. Using categories with blocking is also beneficial when you want to display important messages.When you want to display the number of lines of text in a single group information, it is preferable to use a predefined bit in the packet indicating the first packet in the group. In the format shown in Fig. 9-13, it is a bit CDS/bit 4 symbol 1 package 2. After changing the category of the start information of the packages you have selected yet get the situation, when a group of text lines is always present in the sequence to start from a given position on the screen forward, for example, from top to bottom.The microcomputer 12 is connected to a memory 14 menu, which codes for lines of text that make up the group menu for dialog control, remember. Each line of the menu text should be prescribed command code that is also stored in the memory menu. The microcomputer is loaded by the program to supply strings encoded test menu in scheme 13 conversion, so you can display the menu on the display 15. The microcomputer is connected to the tool 16 selection menu for the displayed line of text menus. The tool selection menu contains the keys of the label control to move the label displayed on the display screen, and press the selection to select a line of text menu, the specified label. When the user selects a line of text menu found on the label, marks the corresponding command code.The table below shows an example of how information menu can be saved in memory 82 menu.The first column on the left indicates an index address position in the memory that contains the combination of a line of text menus and command code. Command codes toderash menu is in memory: menu index addresses 001-006, menu index addresses 080-83, menu index addresses 0100-0103 and menu index addresses 0123-0125.Four different types of commands must be different in the table if:
the first type (jump) to initiate the search data stored in place on the recording medium indicated by the address, consisting of a command code. This address can be an absolute time code recorded in the Q-channel sub-code, or number of images recorded with the video data. When elected, the text string corresponding to the command type, the microcomputer initiates the search function by circuit 8 controls. The control scheme is a scheme of a conventional type, which can control the search text specified address code. The command line of this first type are stored in memory locations specified for example, the index addresses 0080 0081 and;
the second type, which enables the display of another menu, the specified index address, composed of command codes. This type of command codes stored, for example, in the memory locations specified index addresses 0006 and 0083;
the third type to select the main and/or category packages subject to separation from the stream of packets received Miami 001 and 0082;
the fourth type to install the display on and off to display the encoded text filed with the microcomputer to the conversion circuit 13. This command type is stored in the memory locations specified, for example, the index addresses 004 and 0125. The computer also downloaded program to install the display in response to pressing a given key. In this approach, pressing this key is detected by the microcomputer and the display is set to the on position by sending the command to INSTALL on the schema 13 conversion.Shown in the table example shows only four types of different command codes. However, it should be clear to the person skilled in the art that can also be used with other types of commands to control devices of any type through interactive reading type codes pause command to create a pause during playback, command of silence to create silence in the video or audio output commands for the game to start reading data.Information menu is written in podkapova channel read records in the formats shown in Fig. 9-13 and preferably information also done visual before you run good or videocodezone disk information menu can be recorded before the beginning of the first information track: channel read-write predpisy track (track 01 under 00) between the end of the title track and the beginning of the first information track. When the information menu recorded before the first data track, the information menu can be retrieved and loaded into memory before playback through the use of transitions performed directly after reading the TOC of the encoded sub-code in the input area. For download information menu the memory menu microcomputer programmed to identify the index codes in the packets selected main category and memorizing lines of text coded menus and corresponding command codes in the addresses specified index code.String encoded text and command codes with the specified index code, for example 00, not recorded in the memory. Command codes with these index codes are executed directly. This allows the execution of several commands before loading the information menu in the memory, such as commands to install the main and category to start searching and reading places in which recorded information menu, with subsequent otoplasty.In Fig. 14 shows the cells that can be remembered starting information in podkapova channel read-write encoded disk or the encoded video. Position 17 marked the track in which the recorded encoded signal. The beginning of the track is an introductory track 18 in which is recorded a table of contents (TOC) in the Q-channel sub-code.The first information track with a sound information (track 1 index 1 denotes position 19. Between the introductory track 18 and the first data track 19 track is located pre-pause (track 1 index 0). In terms of track 17, which is located after the introductory track that is an absolute time code that indicates the position information (address), in the Q-channel sub-code.In podkapova channel read entries recorded instruction containing the address THAT indicates the start of the account starting information, such as information menu in podkapova channel read-write on track 20 pre-pause. Symbols SA marked secure distance between end of table of Contents and the beginning of the information menu. Channel Schetyna records in the first track (track 1 index 1) may contain further the keep, and a Move instruction containing the address THAT is read from a channel read-write. After recording in the internal memory table of contents is executed, the instruction containing the address TA and the information menu is read and written to the memory menu. The use of command codes that are directly executed after restoring, you can call the function pause after loading the information menu and display the menu or picture. When using directly executing command codes you can start by reading one of the data lanes without displaying a menu on the display. The duration of the track 19 pre-pause corresponds to the playback time is in the range of 2-3 s, this means that about 200 lines of text menus can be saved in the track 20 pre-pause. However, if you want to record to internal memory more lines of menu text, further information menu can be recorded in podkapova channel read-write parallel with any part of the program the main information. In this case, it is preferable to mute the output audio and visual information during recovery information read record command to kill recorded on doroteo and powerful interactive control code for the player and the code of the video formats described in the signal read-write allows fast display additional text information about the audio or video information, recorded on the media.The use of different categories of information allows you to record text information in different languages with different codes main categories, so that every user can choose the language with which he almost familiar. The use of different sub-categories allows for easy selection of the type of information to be displayed. Because packets of different categories are interleaved, and the transmission speed information recorded in the signal read-write, is high (75 packets per second), the chosen type of information in the desired language appears quickly. This high speed data transmission has the advantage that the information in the packet can be repeated several times without a noticeable decrease in access time to the information.The program information transmission via subchannels read-write especially suitable for 5-inch encoded video that can be recorded about 20 minutes of audio information and 6 min video. During the time interval when it can reproduce only the audio information, and may display the information recorded in the channel read-write. Drugged is these channels are typically not used in the respective encoded discs with audio information and video information. This means that the coded audio disks and encrypted DVDs recorded in podkapova channel read-write information can be read without any problems at famous players encoded audio and video.It is shown in Fig. 13, the device can be expanded two-line display 15A of the liquid crystal, which can be controlled by the microcomputer in the control circuit 13A conventional type to display lines of text code provisions in the text LSD 1, LSD 0 01 or 10, indicating the first or second line two-line display. As mentioned, the location code in the text LSD 0, LSD 1 00 is used to indicate that a line of text should not be displayed with two rows. The location code in the text LSD 1, LSD 1 11 causes twisting of the information displayed on the two-line display 15A before a new line of text appears on the bottom line.The device shown in Fig. 13, may be expanded second memory 14a menu type of long-term memory, in which lines of text menus and commands recorded constant the signal, system videolibrary or control additional devices such as a tuner, VCR, etc. To enable switching from the memory 14 to the memory 14a menu and Vice versa in each memory menu memorized custom command code to change the memory menu, which is used, or control keys. The use of both devices storing menu information menu is stored in the same format has the advantage that the control-dependent scheme function and management of interactive recovery of recorded information on the information carrier can be carried out by the user in the same way, which means that is very easy to use interface.In the above example of the invention shown for the encoded disk. However, this invention can be used with other systems record information such as audio tape systems.And finally, it can be noted that in primered transmitted only coded text and command codes. However, you can also record other information in the packet type, for example, compressed image, code objects, synthetic speech, etc. 2.

FIELD: protection of video information against unauthorized copying.
SUBSTANCE: proposed method using watermarks to protect video information against unauthorized copying by changing scale of pattern in the course of copying includes introduction of watermark in original video signal with different scales. Watermark is maintained in each scale for preset time interval sufficient to enable detector circuit in digital-format video recorder to detect, extract, and process information contained in watermark. Watermark scale is changed by end of preset time interval preferably on pseudorandom basis to ensure appearance of each of all scales in predetermined scale variation range as many times as determined in advance. In this way definite scale possessing ability of watermark recovery to initial position and size can be identified and used for watermark detection.
