The recording media (options)

 

The invention relates to the recording of moving images. The recording medium contains a moving image is divided into a number of basic blocks and main blocks associated with the moving image recorded in each basic block. The main unit contains at least one kind of data. Information main blocks includes status information of the first audio and second audio. Audio can be original or secondary and may be fictitious. The main blocks are encoded with variable bit rate and information of the basic block includes information about the position of the data in the corresponding basic blocks in accordance with the playback time. The main blocks are grouped into video objects, each information main blocks generated in the information of video objects, each video object recorded in a separate file, and the media is a digital versatile disk (DVD). The technical result - the ability to play original or secondary audio encoded with variable speed by using the positional information contained in the basic blocks. 2 C. and 10 C.p. f-crystals, 11 ill.

The description of the relevant field of technology Sovershenstvovanie in the field of digital compression and increase the capacity of the recording media now allows information about moving images, compress them into digital data and to write. The compression methods include a variety of standards. In the case of video, now the most widely used standard MPEG compression moving image) - 2 video (ISO/IEC 12818-2)MP@ML (main profile at main level), which has the same image quality that modern TVs. Using standard MPEG-2 MP@HL (main profile at high level), which allows you to achieve the image quality of high definition television (HDTV), increases dramatically. In the case of audio, AU (audio encoding)-3 commonly used in North America, and the standard MPEG1/2 Audio (ISO/IEC 13818-3) used in Europe. The volume of the audio data is smaller than the amount of video data so that the standard linear pulse code modulation (LIM), in which there is no compression, can also be used for audio.

Thus, audio data and video data are processed signal in accordance with paragraph shall ndart MPEG-2 System (ISO/IEC 13818-1). Namely, every audio and every video are combined into a package, and each package adds information about the discernment to distinguish between audio and video, information about the buffer management and synchronization information to synchronize audio with video. The synchronization information related to the synchronization signal, which will be used by the decoder, is also added to each packet, resulting in Packed data. Here, the video standard digital versatile disk (DVD) prescribes that one data packet is comprised of 2048 bytes.

Normal recording of the moving image, includes several important features, such as the function after recording for replacing and overwriting only the audio portion of data among the moving images that have already been recorded on the recording medium. Existing analog recording media have the tracks on which the video signal for the moving image and audio signals are recorded separately, so that the function after recording is easily doable. Also, the analog signal is not recorded in a specific recording unit, so that the operations required for after recording, completed by overwriting the desired part.

Here, AU is about and recorded later, called the secondary audio. In order to protect the original audio after recording, secondary audio, you must prepare two separate audio tracks for recording the original audio and secondary audio. Accordingly, the original audio and secondary audio should differ from each other with regard to their tracks.

While playing these two tracks, a secondary audio signal is generated only when the audio signal is in the track secondary audio, or if you receive audio in the track for the original audio. In this case, may play a secondary signal, which was partially recorded on the track. If it is desired to play back only the original audio, the audio signal of the original audio track can be played regardless of the existence or nonexistence of audio signals on the secondary audio track.

However, in digital recording media, audio/video (A/V) signals were either recorded on the recording area in a given block record without classification, so that the recording and playback of secondary audio using the method of overwriting used analog recording medium is impossible.

Brief isogenies image divided into a number of basic blocks and main blocks associated with the moving image recorded in each basic unit, in which the main unit contains at least one kind of data among video data, audio data and graphic data, and audio data containing the first audio or first audio and second audio information of the basic block includes status information of the first audio and second audio; status information of the first audio represents the state of the original audio, in which the first audio is original audio, or a secondary audio in which the first audio is secondary audio recorded over part or all of the original audio; and the status information of the second audio represents a state in which the second audio is original audio, a second state in which the second audio is secondary audio recorded over part or all of the original audio, a third state in which the second audio is dummy audio which is exactly the same as the first audio, or a fourth state in which the second audio is secondary audio overwrite part of rmacy main blocks includes information about the position of the data in the corresponding basic blocks in accordance with the playback time. Basic blocks can be grouped into video objects, each information main blocks generated in the information of video objects, each video object recorded in a separate file, and the media is a digital versatile disk (DVD). The recording medium further comprises bundles that include many of the basic blocks and the corresponding information of the basic blocks where each packet includes a header packet information of the basic blocks in it, the title of the tutu has a thread identifier with information about the state of the first audio and, if the second audio exists, the status information of the second audio. Packs include many of the basic blocks and the corresponding information of the basic blocks where each packet includes a header packet information of the basic blocks in it and a payload, the header stack is the thread ID, and the payload have a thread identifier with information about the state of the first audio and, if the second audio exists, the status information of the second audio.

Another option of recording media includes a moving image is divided into a number of basic blocks and main blocks associated with moving their data video data, audio data and image data, and audio data containing at least audio of the same type, and the basic information blocks includes first state information associated with the audio stream of the first type, and the first state information represents a state in which the first audio is original audio, or a state in which the first audio has been modified from the original audio, and basic blocks are encoded with variable bit rate, and the basic information blocks includes information about the position of the data in the corresponding basic blocks in accordance with the playback time. Information main modules additionally includes the second state information associated with the audio streams of the second type, and the second state information represents a first state in which the second audio is original audio was the second state in which the second audio has been modified from the original audio, a third state in which the second audio is dummy audio which has the same thread as the original audio, or a fourth state in which the second audio has been modified with a dummy audio. Information main blocks on the status information represents the first state, in which the second audio is original audio, or a second state in which the second audio has been modified from the original audio. Status information additionally includes a third state in which the second audio is dummy audio which has the same thread as the original audio, or a fourth state in which the second audio has been modified with a dummy audio. Information main modules additionally includes the second state information associated with the audio streams of the second type, and the second state information represents a first state in which the second audio is dummy audio which has the same thread as the original audio, or a second state in which the second audio has been modified with a dummy audio.

Description of the preferred option
The recorder and player for digital versatile disks (DVD), shown in Fig.1, adopted as the preferred option of recording device and playback device that applies this invention.

In Fig.1 blocks 102-114 are designed to play, and blocks 116 and 126 - for the record. The playback device may include only the blocks for playback and recording device may include only the units for recording. Block 100 optical head autom is hisoutensoku interface, and system controller 130 to control the operation of each unit included in the recording device and the playback device.

Conventional tape recorders can record and reproduce, so that all units can be installed in a single device. Thus, in this invention, if the recorder runs on playback, it may be a playback device.

The operations of blocks in the General playback device, the block 100 of the optical head reading from the CD-ROM includes an optical system for reading a signal from the recording medium and converting the read signal into an electrical signal, and a mechanism for moving the optical system so that the optical system to read and write data in the desired positions on the recording medium. This mechanism is controlled by a digital block 102 of the automatic control system. The amplifier 104 radio frequency (RF) amplifies the electric signal read from the recording medium by the optical system, and delivers the resulting signal to the decoder 106 data. Also, the amplifier 104 provides RF signal of the automatic control system to compensate for the position of the optical system for digitally the first signal, issued by amplifier 104 RF, digital signal expressed levels "0" and "1" based on the signal level (which is level binarization). This digital signal has been modulated in accordance with the recording characteristics of conventional recording media. Also, the decoder 106 data demodulates the digital signal in accordance with a demodulation scheme corresponding to the modulation scheme used after modulation. This demodulated digital signal is a signal error correction code (KIO), to which is applied a parity for error correction, caused by scratches, defects or anything like that on the recording medium. The decoder 106 corrects data generated error by decoding with error correction demodulated data and provides the encoded error correction data to the audio/video (A/V) decoder 108.

The data output by the decoder 106 data has a form that has been compressed at least one of video data, audio data and graphic data. The audio data may not be compressed because they have less information regarding the amount of video data. Video data is typically compressed in accordance with MPEG standard. Image data compressed in sootvetstvujuschie data in accordance with the relevant compressed schemes to restore video, audio and/or image data. In particular, image data are mixed with the video data.

The memory 110 connected to the A/V decoder 108 temporarily stores data received A/V decoder 108, before decoding the data, or temporarily stores the recovered data before issuing the data. Then, the data provided from the A/V decoder 108 are converted for output by the output device. Namely, the video digital to analog Converter (DAC) 112 converts the restored digital video data into an analog video signal and outputs the analog video input of a TV or monitor. Audio DAC 114 converts the restored digital audio data into analog audio signals, and outputs the analog audio signal to a loudspeaker or amplifier. TV, monitor, loudspeaker and audio amplifier, which are the final output devices, not shown in Fig.1.

When working units in the recording device, audio or video are taken from an external input device. Here, the external input device may be a TV, camera, etc. and are not shown in Fig.1.

The received video and audio signals are analog or digital form and, accordingly, pre-treatment is but the video processor 116 performs the same function as the operation of the filter to minimize the secondary effects that take place at the same time as the analog video signal is converted into digital data, and then converts the analog signal into a digital signal. Audioproperties 118 performs the same function as the operation of the filter to minimize the secondary effects that take place at the same time as the analog audio signal is converted into digital data, and then converts analog audio to digital audio. A/V encoder 120 compresses the digital audio and/or video signals to reduce the amount of audio and/or video data, and accordingly processes the compressed audio and video signals. Namely, the video is usually encoded using a compression scheme called MPEG (ISO/IEC 13818-2), and audio is usually coded using such compression schemes, as AC-3 or MPEG audio (ISO/IEC 13818-3). However, the audio may not be compressed because it has a smaller data volume relative to the volume of video data. Usually information based on the system standard MPEG (ISO/IEC 13818-1) is added to the encoded video data and encoded audio data. This information is required to decode both video the chronicity of the audio with the video.

Graphical data is generally accepted as a special input device. Alternatively, the image data produced by the system controller 130, which receives the user input, special compressed by the compressor, and mixed with the data of the A/V In A/V encoder 120 can perform the compression and blending the graphics data. However, part of the graphics data are not shown in Fig.1.

The memory 122 connected to the a/V encoder 120 temporarily stores data, the received A/V encoder before encoding the received data and temporarily stores the encoded data before the coded data will be issued. The encoder 124 data error correction encodes the encoded output A/V encoder 120, and modulates the encoded data with error correction in accordance with the recording characteristics of the recording media. The controller 126 of the power of the laser diode (LD) emits an optical signal corresponding to the output data from the encoder 124 data on a recording medium using a laser beam, thus making the entry.

Block keyboard input and display 128 that is designed to create a user interface with the device recording or playback, accepts a command such as start playing, stop the play is 130, and shows the user's selection on the menu, on screen display (OSD optical scanning device) or the graph on the screen (OSG). System controller 130 transmits the functions required in accordance with each operating command set by the user, all blocks and controls these units, thereby performing the operation set by the user.

A/V decoder 108 and A/V encoder 120, separately installed in Fig.1, can be integrated into a single unit that can perform encoding and decoding. Also, the memory 110 for decoding and memory 120 for encoding can be integrated into a single memory.

Accordingly, when the optical recording device/playback shown in Fig.1 writes the moving image on the recording medium, it shares information about the moving image into multiple basic blocks, and writes this set of basic blocks on the recording medium using the blocks recording 116-126 and 100. System controller 130 provides the information required for playback/editing for each main unit and manages the basic blocks. Information main blocks provided by the system controller 130, zapisyvaete the CD-ROM.

Here, the main unit includes at least one of video data, audio data and graphic data. In particular, the audio data include only one type of audio or includes the first audio and second audio. When a user has a secondary audio secondary audio recorded over part or all of the first audio and second audio, and the modified state of the first audio or second audio is managed as state information of the first audio and second audio information within basic blocks. In the case of DVD videos that is the preferred option of the present invention, the main unit is called a video object (VO), and the information of the basic blocks is called (IVO).

During playback, the system controller 130 checks the status information of the first or second audio stored in the basic information blocks, which is played through the unit 100 of the optical read head, the RF amplifier 104 and decoder 106 data, and controls the block input from the keyboard and display 128 to display information about the status of the audio information of the basic blocks in the menu, and so on, so that a user can recognize the information about the state of audio. Therefore, according to the choice of polzovateley, play blocks 100-114 for playback, as shown in Fig.1. This will be further described with reference to Fig.5-7.

Now will be described a hierarchical data structure of the moving image, with reference to Fig.2 to facilitate understanding of the present invention.

When recording the user data of the moving image data of the moving image is actually recorded on the recording medium using blocks 116-126 and 100 for recording shown in Fig.1. In DVD videos every recorded data is divided into blocks of video objects (VO). Namely, the data of the moving image recorded from the moment when the user clicks on the button to start recording until, until you press stop recording, is one.

Many IN is recorded on the recording medium. For example, IN 1, IN 2 and IN 3 shown in Fig. 2. As described above, video data, audio data and graphic data are mixed and recorded in one IN. In this invention these IN are called binary stream real-time, and each is written IN a single file in the case of DVD videos.

When playing back recorded DURING decoded and reproduced blocks 100-114 to play, PNA and length (resolution) video data within the respective, the encoding scheme of the audio data, etc. can be recorded separately. Also, when encoded IN variable bit rate (SPB), the position data within the vo does not match the playback time. Accordingly, a separate record position data in accordance with the playback time is useful for performing special playback functions such as time search. These data are IVO. Namely, IVO (MR. 1, MR. 2 and MR. 3, shown in Fig.2) is present in each and every IVO includes the information required for playback or editing appropriate.

The program can be a block of information of the moving image to the user. Namely, the user understands that the recording medium recorded many programs. In DVD videos, the relationship between the program and can be determined as follows. Namely, the program includes a variety of cells and cell denotes a part or whole. Subsequently, the program includes some or all of the lots IN.

Usually, the program includes a cell, and the cell match a whole. Here, when the program is subjected to the editing process in response to a command from the user is a user, the program becomes a bit more complicated than the above normal form.

Information associated with many programs is the information chain programs (PPI). IVO and PPI are the navigation data. Namely, the binary stream real-time data which is moving image, and the navigation data, which are information required for reproducing data of a moving image are recorded together on the recording media.

As described above, the program eventually recognized by the user. Here, the program is transferred to the user, using the menu, etc. displays menu corresponding to each program (for example, program 1, program 2 and program 3 shown in Fig.2). When the user selects a program n, found cell belonging to the selected program, and reproduces the relevant parts IN specified these cells. The information required for this play, can be obtained from the relevant IVO.

Fig.3A and 3B show the internal configuration, shown in Fig.2. In Fig.3A and 3B IN includes many blocks videoobject (BWO), and each BWO includes menajet MPEG, used as a method of video encoding, uses the correlation data between frames of the moving image.

In data of a moving image composed of tens of frames per second, each frame typically includes the same information. For example, in the case of moving images, moving people, the background of each image is the same, and there is only a small amount of motion in each frame because of this man. Therefore, the front frame is recorded completely, and in the next scene, recorded only the parts that differ from the previous frame. Thus, the amount of data that you want to write, is sharply reduced.

How to encode MPEG conceptual uses this notation. In this case, there is a disadvantage in that the average frame requires a recovery of the previous frame. So even if you want to play middle frame, frames, preceding, must be reproduced starting from the front frame. MPEG allows this disadvantage by using the group structure of the image (GI). Namely, the specified number of frames constitute a group, and all information on the footage is recorded on the front frame of this group.) - Rev. Affairs GI, belongs to the middle frame. Typical GI consists of 12-15 frames. BWO includes many GI.

BWO includes many video packets, audio packets and/or packets of image data in a form based on the standard of the MPEG system. Each package includes information about its type.

Fig. 3A relates to a case in which the type of the audio stream exists for a single video stream formed in the form of a package, and Fig.3B relates to a case in which two types of streams exist for a single video stream formed in the form of a package. If there are many types of audio streams, as described above, the user can select and play the desired type of audio stream.

Now the package structure will be described in more detail with reference to Fig.4A-4D. The package usually includes the tutu. In the case of DVD videos, one package requires at most two packs. If you want two packs, one pack among the two should be tutu filling insignificant information just for classes designated on the data.

Each pack is divided into the header stack and part of the payload. In the header of the pack provides information representing the type of the corresponding stack as the argument that the measures "1110 0000b", as shown in Fig.4A. In the case of audio, audio only MPEG can be represented as a thread ID (stream_ id), as shown in Fig.4B, and the thread ID (a file_id) is "1100 000xb". Here, x is 0 or 1, can provide two types of audio.

If audio is audio AC-3 or the audio LICM require an additional procedure to identify audio AC-3 or the audio LICM. Namely, audio AC-3 audio LICM have the same thread ID (a file_id) "1011 1101b". The header information corresponding to audio AC-3 audio LICM, is recorded in part of the payload, and the recorded information of the header followed by the actual audio data. The header information includes a parameter called ID substream substream_id. In the case of AC-3, "1000 000xb" is stored in the ID parameter substream (substream_id), as shown in Fig.4D. In the case of LIM, "1010 000xb" is stored in the ID parameter substream (substream_id), as shown in Fig.4C. Here, x can be "0" or "1" that can provide two types of audio. In this invention, when x is "0", this case belongs to the first audio (audio 1), and when x is "1", this case belongs to the second audio (audio 2).

The first audio is used on the first audio. In this case, the original audio, which is rewritten secondary audio is removed.

The second audio can be used to record the original audio or to record the secondary audio. If the second audio is used to record the original audio, you have two of the original audio with the first audio. However, the original audio is not recorded only on the secondary audio of the first audio. If the second audio is original audio, the user recognizes the second audio is original audio from the beginning. Therefore, the first audio and second audio have the same priority. When recording secondary audio selects either the first audio or second audio, and then the secondary audio is recorded on the selected audio.

When recording the second audio is secondary audio from the beginning, consider the following restrictions. Upon initial use must be recorded second audio of the same content with the content of the first audio. Namely, the second audio is the same as the first audio in the sense of content, so the user cannot recognize the second audio. This state is called the state of the dummy audio.

Accordingly, if the user wishes to record a secondary the AI. If the second audio is overwritten secondary audio thus, it is recognized by the user, and the user selects and plays one audio among the first audio and the second audio. Since the second audio is the same as the first audio, except the part which contains the secondary audio is played the same content, even if the audio selection is changed. The reason why the recorded second audio having the same contents as the contents of the first audio, is that in the case of digital recording media, it is difficult to select and play the part, on which was written the secondary audio. Namely, if the second stored audio and only part of it is occupied by the secondary audio, audio is not played with the parts on which secondary audio is not recorded, if the second audio that will cause confusion for the user.

Alternatively, the first audio can be played in empty parts of the second audio and secondary audio can be reproduced in parts of the second audio, which was recorded secondary audio. However, in this case, should be made by determining whether the recorded audio on the second of audio, making it difficult to achieve alternatve before what these States are written to the appropriate IVO in and play with them, or are used to carry out relevant operations when the user has made a change the audio during playback.

Fig.5 shows an example of the structure of the status information of the first audio and status information of the second audio within the information of the video object (IVO) in accordance with this invention.

Information AO_ STATUS about the state of the first audio represents a state (00b), in which was written the original audio, or a state (01b) in which part or all of the original audio is secondary audio.

State 00b is that the first audio is original audio. If the second audio is not recorded, the user writes the secondary audio over part or all of the original audio. At this time, the first audio rewritten secondary audio, and status information of the first audio is changed to "00b" to "01b".

Information A1_STATUS about the state of the second audio can be fictitious state 10b, in which the second audio is completely the same as the content of the first audio, or a state 11b, in which a part or all of the second audio was rewritten secondary audio, anywayse as information A1_STATUS about the state of the second audio.

As a result, information A0_STATUS about the state of the first audio information A1_STATUS about the state of the second audio are defined as follows.

A0_STATUS:
00b ... the first audio is original audio.

01b ... the first audio is secondary audio, overwrite part or all of the original audio.

A1_STATUS:
00b ... the second audio is original audio.

01b ... the second audio is secondary audio, overwrite part or all of the original audio.

10b . . . the second audio is dummy audio, the content of which coincides with the content of the original audio.

11b . . . the second audio is secondary audio, overwrite part or all of the dummy audio.

In the method using the information of the first and second audio, the case in which the second audio is dummy audio is the most important. When the recorded state information representing that the second audio is dummy, it is considered by the user as the case in which the second audio is not recorded. Thus, this situation can be shown in menus, etc. All the time, even when the user performs the function of converting audio, first of AU the giving of the first audio can be set by default.

When the second audio in one of three States 00b, 01b 11b, and unable 10b dummy audio, these three States of the second audio indicate that the recorded audio data having content different from the content of the first audio. Thus, the user is informed of this state of the second audio, and therefore, can perform the replacement audio. In particular, if information A1_ STATUS status of the second audio is the state 11b, in which the second audio is secondary audio that is overwritten on part or all of the dummy audio playback of the second audio can be set by default.

Accordingly, in this invention, the user is informed whether the first audio or second audio is original audio, or a secondary audio that is overwritten on part or all of the first audio and second audio, via menus, etc. so that the user can recognize the state of the corresponding audio IN.

Fig. 6 shows the variation of the state from the state before will be overwritten secondary audio to the state after the secondary audio was overwritten when there is only the first audio. Namely, case (A S-TUS= 00b) of the first audio in the state of or torigny audio b1-b4 by overwriting/editing it is shown in Fig.6. In this case, information A0_STATUS about the state of the first audio updated to "00b" to "01b", and the variation of the state of the audio can be displayed on the screen through the menu, etc. on the block keyboard input and display device 128 shown in Fig.1, so that the user is informed about the variations of the state of audio.

Fig. 7 shows the variation of the state from the state before the secondary audio will be overwritten to the state after the secondary audio was overwritten, when the first and second audio. If the first audio is original audio (i.e., (A0_STATUS=00b) and the second audio is dummy state in which the second audio is identical to the first audio (i.e., A1_ STATUS=10b), the default is the reproduction of the first audio, and the direction of the reproduction is indicated wide solid arrow.

The second audio state dummy audio, with some sections A5-A8, rewritten secondary audio b1-b4 shown in Fig.7. Information A1_ STATUS status of the second audio is updated to "10b" to "11b". Here, the first audio remains in the condition of the original audio (i.e., (A0_STATUS=00b).

Part of the second audio in the fictitious state corresponds secondary audio, and then replacement is the network wide solid arrow, indicate the direction of play. Namely, as shown in Fig.7, the first audio A1-A4 are reproduced, the second audio b1-b3 in the second of audio, then played for replacement audio user, and the first audio is reproduced again from the A8 because of the replacement audio by the user.

As described above, in this invention, the status information of the audio associated with the moving image obtained by writing/rewriting/editing, is stored in the information recording unit IVO for the appropriate unit of account, and shall be communicated to the user prior to playback of the moving image, so that the user can recognize the status of the audio. Also, during playback, the user can respectively to cope with the replacement audio.

FIELD: optical data carriers.

SUBSTANCE: for protecting optical disk from recording, information concerning protection from recording is read, which is previously recorded in at least one zone of starting or ending area of data carrier, and it is determined, whether the latter is in state of recording protection. In variant, when carrier is placed in cassette body, and body has aperture for forbidding recording protection of data on disk, it is determined, if recording protection state of recording protection data written on disk is matches with state of recording protection of said aperture, and recording of new data is prevented, if said protection data and aperture position forbid recording. In a variant information concerning recording protection is stored in zones of disk identification of at least one of zones of starting and ending area of carrier.

EFFECT: higher efficiency.

FIELD: data carriers.

SUBSTANCE: data carrier uses address table, which assigns time information to given data portions and wherein each of said portions includes constant number of bits. Said portions contain data packets, for each input into address table. Each of said portions is assigned with value of duration change in time. Each such value is assigned with current index. Said value is difference between time of receiving first packet of portion data and time of receiving data packet, following directly after last data packet of this portion, to receive value of required address of goal portion on data carrier. All value of duration change in time for portion having said goal address are added to increasing total. Appropriate current index for inputting change of duration in time, related to said closest value of duration in time, is multiplied by given constant number of bits to calculate said address value of goal portion.
