DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, specific embodiments of the invention will be described in detail.

[Information Recording Medium]

Example 1

The information recording (referred to as D11) medium of the multi-standard program of the present invention, SP: Dll disk, including D11 optical disk, D11 magnetic disk, D11 electronic disk and D11 magnetic tape, etc., are stored on the D11 disk and include as shown in FIG. The following contents: partition table, multiple (at least two) program compression data, multiple (at least two) program navigation information, may also include system navigation information. The system navigation information may also be stored in a corresponding playback device, and the partition table includes system files of the D11 disk.

The program compression data, that is, the data layer, is a data file obtained by compressing a program source by the same or different compression methods, and the program may be a VCD movie, a DVD movie, an SVCD movie, a CD audio program, an MP3 audio program, Still pictures, video games, etc. contain at least one type of video and/or audio data files. Of course, the compression system of the plurality of program compressed data may also be the same. The data file contains system packages, data packets, headers, and packet data as specified by each program format. Multiple programs are compressed in the data.

The program navigation information is navigation information corresponding to the compressed data of each of the above programs, and the content includes: a program identifier, a program attribute, and a start address. The program identifier defines a number of the program, and the program attribute may include a video decoding identifier, an audio decoding identifier, a resolution, and the like.

The system navigation information, for a plurality of different compression system program compression data, performs program linking, and includes, in the system navigation information, a programming of each program, that is, a section that starts playing. The definition of the target, and the order in which the programs are played, etc., • User function key definitions, which can include, for example, - stop, play, previous, next, pause/step, volume +/-, mute, or OK button, etc. The definition of the function key.

For the convenience of the user, the directory table of each program can also be stored in the D 11 disc.

In order to ensure the genuine release of the D11 disk, the security authorization information can be stored in the D11 disk.

Of course, the system of compressing data of the plurality of programs may also be the same.

Example 2

The other conditions are the same as in Embodiment 1, except that the following contents are added:

The compression-encoded program is defined as a plurality of segments. In the plurality of program navigation information, the number of segments, the starting address, and the natural attributes of each segment, such as: resolution, starting offset address, are stored. , End offset address, length of time, etc. Specifically: In order to divide the program into smaller segments, according to the player's memory, it is better to divide the program into multiple segments according to the principle that each segment contains at least one key frame, such as: 1024 segments, and each The natural attributes of the segments are recorded in the corresponding program navigation information, so that each program compressed data is divided into several segments, on the basis of which each segment can be processed.

Correspondingly, in the system navigation information, a definition of controlling the segment of each program, that is, a definition of the playing time, the space, and the playing effect, such as: an object attribute that can be used for each segment of the different program, is added. Properties, button controls, etc. are defined.

Specifically, the object attribute may include: 1 a starting object attribute to be played, that is, a program identifier to be played initially, a clip serial number; 2 spatial attributes: a position coordinate of the clip to be defined in the screen, a layer, Resolution, etc.; 3 time attribute: the time when the clip to be defined appears and disappears in the screen; 4 time attribute: defines the playback loop or stops after the broadcast; 5 group member description: can describe information for multiple segments, through the operator To describe a large number of connected segments.

The command attribute may include designation of various commands for processing a segment to be defined, wherein

1 command type, can include jump, conditional judgment, special effects, assignment, random number, call, mask/enable button, read/write user defined area and other commands. This command defines the playback effect of the clip, mostly in the prior art. Now I will explain some of the commands and the functions that can be implemented: (a) Jump refers to not playing in the normal order, jumping to other clips, The label is the fragment number to be jumped; (b) The conditional judgment refers to the judgment of the condition if the condition occurs, and the condition may be the assignment set here. Variables, can also be the capture of user key commands; (C) special effects include special playback, stereo generation, softening, tone adjustment and transition effects, where special playback includes reverse fast forward, fast reverse, slow, fast , Repeated loop playback, etc., transition effects include fade in, fade out, flash white, draw frames, and so on.

2 Execution order: Define each command to be executed before the object is played or after the object is played.

The above commands can be nested, and a single fragment can define multiple commands at the same time. In the system navigation information, whether the above-mentioned commands are executed for the segments to be processed, that is, the play form of each segment in the program can be flexibly defined, thereby realizing various flexible link and control modes. For the same segment of the same program, multiple different definitions can be made to make the playback order, effect, and the like different, so that the same program can select multiple different playback versions during playback.

The button control, in addition to the function keys described in Embodiment 1, can also define the key control for each program and each program segment, including setting advanced navigation keys, such as: current program menu, title, settings , angle, channel, subtitle, on-screen display, system, search button, you can also set multimedia navigation keys, such as: program switching button, instant special effects button, multi-program menu, game, channel, subtitle, 2D/3D graphics control button . All the function keys are only for the convenience of the user to control the playing of the program. The invention is characterized in that the button definitions can be separately performed on the segments separated in the program.

In the system navigation information, in order to facilitate user control, the definition of the user interaction menu may also be included, and may include definitions of various aspects such as the position, color, command, and button of the menu.

[Information Recording Method]

Example 3

The recording method of the information recording medium described in Embodiment 1 or Embodiment 2, that is, a method in which a program source is created as a D11 program and recorded on the information recording medium (D11 disc). The specific flow chart is shown in Figure 2. In the recording process, the program source is mainly produced by the computer host or a plurality of network computer hosts, and then output to the recording information medium (D11 disk) through the recording output device, as shown in FIG. The flow chart is a relatively complete recording process. The process is further explained below:

1) Determine whether to add a new program source;

2) If otherwise enter step 11;

3) If the step 1 is yes, the path of the selected different program source is obtained and stored in the program source table;

4) reading the first program source in the source table of the program;

5) selecting a compression coding mode, and compressing the program source into program compression data by using the selected compression coding method; 6) dividing the program compression data into a plurality of segments, and reading the program compression data. For the program including the video data, the principle of segmentation is to include at least one video key frame in each segment, and the key frame refers to A compressed data packet containing a complete main picture. The other pictures are calculated according to the change of the picture. Each segment must contain at least one key frame to further process the segment. Of course, one segment can be Contains multiple keyframes, where the segmentation is larger; and each video's keyframe has a special header identifier, so when reading compressed data sequentially, you can define the header from one keyframe to the next or the next. Before the header of a key frame, it can be divided into a segment, and the natural attributes of the segment as described in Embodiment 2 are calculated, and then the program attribute, the program identifier, and the start address are added, and the program navigation can be generated. Information, if the number of segments is 1, then the segment is not segmented, and the program navigation information as described in Embodiment 1 is generated; Since the audio data is much smaller than the video data, during the compression process, the audio data packet and the video data packet are stored in an interlaced manner, and as long as a video key frame segment is included, at least one audio key frame is necessarily included. For a program containing only audio data, the key frame refers to an audio key frame;

7) storing the compressed program compressed data into the program library;

8) Determine whether all the program sources to be produced have been processed;

9) If the next program source is otherwise read, go back to step 5, and segment the segments to be processed one by one;

10) If step 8 is yes, proceed to step 11;

11) Select the name and path of the program to be created from the program library and store it in the directory table to generate a directory table of the D11 program;

12) reading the first program in the table of contents;

13) Determine whether the program format needs to be converted. This step is mainly used when recording a program requiring a unified system. For example, for a player that wants to play the D11 disc, only one program compression data can be decoded. In this case, it is necessary to After the original program compressed data is decompressed, it is compressed by the compression encoding method supported by the player, thereby realizing the conversion of the program compression system;

14) If otherwise enter step 16;

15) If step 13 is yes, select the encoding format and complete the program format conversion;

16) reading data of a segment of the program compressed data;

16a) System navigation information configuration for the segment, this step can be based on each segment of the program The content is different, personalized processing, object properties, command properties, button control, etc., such as: Whether to perform special effects on the segment, including stereo technology tone adjustment, atomization effect, transition effect, etc., determine the segment Play time, play position, programs thus processed, such that the same program material can produce a version of an infinite variety of programs. For example: When the film is released, different system navigation information can be used for the purpose of deleting, combining and special effects of different segments, realizing "three-dimensional version", "stunning version", "montage version", "romantic version" Etc., so that it exists in one program at the same time, and the user selects to play. Here, it is necessary to define a plurality of system navigation information for one segment. The other is equivalent to the splicing of objects. When shooting, the film is formed by separate shooting of different materials such as people and backgrounds. The object material is combined according to the time of appearance and the position of the space during playback. The standard movie version can also be realized. At the same time, it is possible to realize a myriad of completely different combinations of character scenes, that is, by interleaving combinations of segments of different programs, for example: in a scene of a certain segment, when a certain content needs to be further explained, it may be after the segment Insert a segment of another program that explains this. On the basis of inheriting the first mode function, you can instantly generate a specific shape through the hardware 2D/3D function, realize the game function, similar to the FLASH function on the PC (that is, the user can organize the background image, foreground animation, music, text) And other information) and instant add-on graphics features.

17) judging whether all segments of the program have been processed;

18) If otherwise stored in the system navigation information, read the next segment of the program, and then return to step 16a;

19) If yes in step 17, proceed to step 20;

20) Determine whether all programs have been processed; '

21) If the next program in the program list is otherwise read, then return to step 13;

22) If yes in step 20, generate a complete D11 system navigation information table;

23) determining whether to generate a multi-standard user interaction menu;

24) If otherwise enter step 26;

25) If yes in step 23, create and test the interactive menu according to the definition in the system navigation information;

26) Determine whether to add an icon file;

27) If otherwise enter step 29;

28) Select the created icon to generate the D11 icon file;

29) Integrate all data and output it to the D11 disk through the recording output device; The above process is aimed at a more complete recording process, in which the first step to the fourth step are mainly used for the management of the program source, and the seventh step to the eleventh step are mainly for the convenience of management, when making each D11 program, first It is stored in the program library of D11 for later use, so when recording the D11 program, if there is no need to make a program library, the above steps can be omitted;

If there is already program compressed data, the compression process of step 5 can also be omitted;

If the information recording medium to be produced is allowed to coexist in a plurality of formats during the broadcast, the process of changing the compression system in steps 13 to 15 may also be omitted;

Steps 22 to 29 are also non-essential conditions, mainly for the integration of program navigation information. The interaction menu is mainly generated for the convenience of the customer; the icon file is an icon displayed on the display during playback, used for advertising identification.

In step 22, a complete D11 navigation table is generated, mainly integrating data of program navigation information and system navigation information, or may be omitted. If there is no system navigation information, steps 16a to 18 can be saved; step 6 is a step of segmenting the program compression data. If the program does not need to be segmented, the number of segments can be defined as a segment during the recording process.

[Information Recording Device]

Example 4

The apparatus for implementing the method of Embodiment 3, the structural block diagram of the apparatus is as shown in FIG. 4, and includes the following parts: recording input device, computer or network computer, display, human machine interface, information recording control device, recording Output device.

The recording input device may include a hardware driver for inputting information source data such as a program source or program compression data, and the recording input device is an optical disc drive for a program source or compressed data stored on the optical disc; for the program source stored on the magnetic tape Or compressing data, the record recording input device is a tape drive; for a program source or compressed data stored on a disk, the record recording input device is a disk drive; if the program source or program compressed data is derived from a network, required The record input device is a network drive. The record input device is for inputting information source data to be processed and recorded into a computer or a network computer.

a computer or network computer, a display, a human machine interface is a hardware device for processing input information source data; and an information recording control device is a software device for processing information source data into the multi-standard information data of the present invention; The structure of the information recording control device is shown in Figure 4. The structure and working process are as follows: The compressed program compressed data is read into the compressed data buffer. Within the data segmentation unit, the data in the compressed data buffer is segmented according to the principle that each segment contains at least one key frame, and the segmented data and program attributes are stored in the program navigation. In the information buffer, if no segmentation is required, only the program attribute is stored in the program navigation information buffer; if a plurality of programs are stored on one D11 disk, the determiner A is used to determine whether all the programs to be segmented are average. completed. If it has been completed, the system navigation information unit, the human-machine interface and the display can be used to prepare the system navigation information for each segment, and the segments to be processed and processed are subjected to object attributes, command attributes, button control, etc. through the human-machine interface. After the definition is completed, the system navigation information of the segment is stored in the system navigation buffer, and then the system navigation information is prepared for the next segment; if completed, the segment of the next program is read again, in the same manner. Prepare its system navigation information; After all the programs to be produced are processed, the complete program navigation information buffer and the data stored in the system navigation information buffer can be generated to generate a complete D11 navigation table, and stored in a non-volatile The data in the compressed data buffer and the data of the D11 navigation table are integrated in the storage medium, and are output to the information recording medium through the recording output device. The recording output device may be different according to the medium to be recorded. If the medium is a disk, the recording output device is a disk drive, and if the medium is a disk, the recording output device is a disk recorder; if the medium is a tape, the recording output device is Tape drive; If used for network storage, the required recording output device is a network drive.

Similarly, corresponding to the recording method, a compression unit that compresses the program source may be correspondingly added in the information recording control device; if the compression system needs to be converted, the system conversion unit may be added; and other auxiliary units may also be added, such as: Test the interactive menu unit, generate icon units, and more.

[Information playback method]

Example 5

A method for playing information on an information recording medium, which can be applied to playback of a D11 disk having navigation information, and can also be applied to a playback method of a common disk without navigation information, and the detailed playback process is as shown in FIG. The following specific explanations are as follows: If there is the system and program navigation information on the information recording medium, the playing method is as follows:

1) Take the D11 icon file and the D11 program list. If there is no D11 icon file on the D11 disk, the icon file is not read.

2) Take the D11 system navigation information, set the initial value of the play, and determine the play mode for the defined clip; 3) If there is an interactive menu, read in and wait for the user to respond to determine the imported program, if not, automatically import the first program;

4) reading the D11 program navigation information of the current program, setting a decoder, and playing the first broadcast segment of the program;

5) Determine the next play clip and effect according to the attributes of each clip, while waiting for the capture user button or network command;

6) If the last clip has finished playing, return to the interactive menu or terminate playback according to the system navigation information, or return to the starting playback unit.

In the above steps, the second step determines the play mode by reading the D11 system navigation information; the function definition of each program and each clip is to be read and played in the system navigation information set in the embodiment 1 or the embodiment 2. The program, in step 5, plays the corresponding play mode to play according to the definition during playback. for example:

I. Stereo: If a certain segment is defined in the system navigation information to generate a stereoscopic effect, according to the definition, the corresponding program is called according to the definition, and the compressed data of the segment is processed to generate a stereoscopic effect and generate a stereoscopic image. The specific steps of the effect can be as follows:

First, the current image frame is acquired and stored in the image buffer 1 and the image buffer 2; secondly, the R register of the RGB (red, green, and blue) of the image buffer 1 is adjusted to 100%; The position of 2 is laterally offset by 3 units;

Adjust the RGB (red, green, and blue) G register of image buffer 2 to 100%;

The transparency of image buffer 2 can be adjusted to 50% of the original;

Finally, the image buffer 2 image is merged into the image buffer 1, and integrated into a stereo image frame.

Of course, the above method may also be changed, but the principle of change is to first acquire the current image frame according to the principle of complementary color, and store it in image buffer 1 and image buffer 2 respectively;

Secondly, the image in the image buffer 1 and the image buffer 2 is adjusted to become a complementary color; then the position of the image buffer 2 is laterally shifted; the number of offset units can be changed, the offset is small, and the stereo effect is Not obvious, the offset is too large, the two images are separated, and there is no stereo effect. When viewing, the same type of complementary color glasses can be used, so that the left and right eyes can only see the image that is consistent with the color of the lens, and the complementary color images are filtered out, thereby generating a stereoscopic effect, and the offset distance is The stereo effect can be produced. Finally, the image of image buffer 2 is merged into image buffer 1 and integrated into a stereo image frame.

After the above processing, the segment to be defined as a stereo can be processed as a stereo effect and then played.

II. Atomization: If a certain segment is defined in the system navigation information to generate an atomization effect, during playback, the corresponding program will be called according to the definition, and the compressed data of the segment will be processed to make the segment have an atomization effect. To produce the atomization effect, just replace the original pixel points in the picture with a white pixel point by row and column by column.

III. Transition: If the conversion between two segments is defined in the system navigation information, the transition effect is used. When playing, according to the definition, the corresponding program is called to process the compressed data of the corresponding segment. , SP : Adjust the hardware brightness register to make the picture brightness of the current clip gradually darken from normal, and the brightness of the picture of the next clip gradually changes from dark to normal.

IV. Hue adjustment: If the hue of a clip is defined in the system navigation information, during playback, the corresponding program will be called according to the definition, and the compressed data of the clip will be processed: First, the user-specified hue The mode is stored in the R-u _Se r, G- _User , B-u _Ser registers;

Secondly, according to the RGB mode specified by the user, the system increases or decreases the stored value of the system RGB according to a specific ratio, that is, adds the value of R-user, G-user, B-user specified by the user and the value of the system RGB register or Subtraction. Finally, the value of the modified RGB register is saved to the system to achieve the effect of changing the hue.

The above several changes are only an example. The further processing of images or sounds is a mature technology. At the same time, it can combine the playback time and space of different segments of different programs. When playing, many combinations can be generated, so that during playback. It will produce a work that can be completely different from the original work.

If it is any program disc without D11 navigation information, its playing method is:

1) reading program files, liming directory and file identification;

2) Determine whether it matches the existing decoded file format;

3) If yes, decode according to the corresponding format, go to step 11;

4) If step 2 is no, read the program data and perform packet scanning;

5) Determine whether it matches the existing decoded data packet header;

6) If yes, decode according to the corresponding format, proceed to step 11; 7) If step 5 is no, look up the decoding library on all paths;

8) Determine whether the decoding library is found;

9) If yes, load the found decoding library, decode according to the corresponding format, and proceed to step 11;

10) If step 8 is no, the decoding library cannot be located and the playback is stopped;

11) User-defined playback function, select segmentation, special effects, jump, button definition, and enter the playback process.

For example, the above program reads the disc format information, determines the file system type (ISO or UDF) and the disc format. If the CD mark is included, the start block is read, the track address is determined, and the CD decoding is used. If the VCD logo is included. , read in the starting block, enter a specific directory, find files, use VCD decoding to play; if the SVCD flag is included, read the starting block, enter a specific directory, find files, use SVCD decoding to play;

If it is other types, find the root directory address information according to the file system information, further find the file information under the root directory, and judge the program format according to the file and directory. If there are: VIDEO-TS and AUDIO-TS directory names, use DVD to decode and play. If there is a .3 file in the directory, use MP3 to decode the music file for playback; if there is a .MPG file, use MPEG1 to decode the image file for playback; if there is a file, use MPEG4 to decode the image file for playback. If there is a .JPG file, use JPEG image file for playback;

If there is no suitable identification file, it can automatically find whether there is a custom program decoding library, if there is, then decode according to its definition; if not, scan the data packet, the general program file is composed of fixed length/indefinite length data packets, The scan of the header, such as 00 00 01 Bx shows that the file type is MPEG2 type, "RIFF" shows that the file type is MPEG1, MPEG4 or other encoding type (determined by FORCC CODE), according to the program information description of the system package, ie The resolution and decoding rate can be determined. The sound decoding information and the superimposed image may be included in other data packets or JUNK blocks. By scanning more than 1000 data packets or JUNK blocks, other auxiliary information can be determined, and decoding is determined in this way. Player, play it.

If the user wants to customize the segment and generate the special effect, the compressed data of the program may be segmented to generate program navigation information before the decoding is played, and then the segment navigation system is configured.

In the above playing method, when a program of a plurality of different standards is played, a program switching process can be set in the playing program, that is, a priority setting table is set at the beginning of the playing program, The priority table defines the order of playing for the programs of different compression methods, so that when playing a D11 disc with a multi-standard program, the order of switching the β-spoon can be automatically determined, and the specific flowchart is as shown in FIG. 6. Show, the description is as follows:

1) Read in the priority table and read the information into the buffer BUFFER;

2) Find the highest priority in the buffer and match it to the first system 5!

3) Find the program in the platter that conforms to J;

4) If there is, play the program, after the broadcast, then jump to 8;

5) If no program matching the standard is found, judge whether the current buffer list has been read to the last position;

6) If step 5 is yes, go back to step 2;

7) If step 5 is no, skip to step 12;

8) Take the system corresponding to the next position of the priority in the buffer, and assign the variable J

9) If there is a standard, go back to step 3)

10) If there is no standard, judge whether the current buffer list has been read to the last position.

11) If step 10 is yes, go back to step 2), otherwise go to 12)

12) Re-read the file format corresponding to the next priority to the buffer, and return to step 3 [Information playback device]
