Description

Method for random playback of multimedia and its title {Method for randomly reproducing multimedia and title

The present invention randomly selects and plays the contents of a movie, a music video, a game, etc. recorded in a multimedia title such as a DVD or a VCD, so that no one can expect the next contents to be played, thereby providing freshness and various enjoyment. The present invention relates to a random playback method of multimedia and its title.

Digital video disks or digital versatile disks (DVDs) and video compact disk (VCD) titles are well known as multimedia for viewing video and audio together, such as movies, music videos or games. Such multimedia generally have a title menu as an interface that allows a user to find and select desired contents, and the player is controlled to play in the order specified in the menu according to user selection.

Referring to FIG. 1, which briefly illustrates a DVD system model, data contained in the DVD 1 is divided into navigation data 2 and presentation data 3. The navigation data 2 is control information necessary for selecting and playing multimedia recorded on a disk. The navigation data 2 includes video manager information (VMGI), video title set information (VTSI), and program chain information (PGCI). program chain information), presentation control information, and data search information. The presentation data 3 includes video data, audio data, and sub-picture data such as subtitles as objects to be reproduced. Correspondingly, the player 4 is largely comprised of a navigation manager 5 and a presentation engine 6. The navigation manager unit 5 reads the navigation data 2 from the loaded DVD 1 and controls the presentation engine unit 6 according to a user's operation. The presentation engine unit 6 reads or decodes the encoded presentation data 3 of the DVD 1 in whole or in part according to a control command of the navigation manager 5, and decodes the encoded presentation data 3 to an external output device (monitor). The reproduction signal is output.

That is, as shown in FIG. 2, the player recognizes that the disc (DVD) is loaded or unloaded into the drive (S21, S25), and when the DVD is loaded, it is based on the order defined in the navigation data contained therein. In accordance with the user's selection to perform the planned playback (planned playback) function to select and play the video contained in the DVD (S24). Steps S22 and S23 indicated together in FIG. 2 are operations for the DVD to which the present invention is applied, which will be described later.

As described above, in the DVD system, the player only takes a simple control operation of the hardware itself, and relies solely on the navigation data contained in the DVD for reproduction of contents such as movies. In other words, it is the DVD that various reproduction techniques can be created according to the intention of the title producer.

In general, a DVD has one or more titles that mean a unit describing one complete table of contents. The title playback method includes a chapter, a title, a part of title (PTT), a program, a cell, a chapter that is a playback unit, and one or more program chains that define these playback orders. It is colorfully defined by (PGC: program chain). For example, a disc that records a plurality of short films treats each short film as a title. In addition, media that a user needs to select and play separately, such as a music video or a game, are treated as one title or chapter.

DVD, on the other hand, has an on-screen display (OSD) menu, an interactive user interface for convenient player operation. There are two menus available on the DVD. One is the system menu, which includes a volume manager menu (VMGM) that can be set commonly for discs, and a video title set menu (VTSM; video title set menu). These system menus are special menus that can be called up at any time during disc playback by pressing specific buttons on the player or its remote control. The other is a selection menu that can be freely created by the title producer and selects the title or chapter described above. This is usually called automatically when the disc is initially driven and after the end of playback of any title or chapter, and the display is usually realized by attaching a button on a still picture or moving picture in the background or on a sub picture. These menus can be called at any time during the playback of a title or chapter by a menu key provided in the player or the remote controller, and the desired title or chapter or another menu can be selected by using the four direction keys.

3 shows a conventional plan play process using the above-described system menu and selection menu, taking a typical DVD movie title as an example. In other words, when the DVD is loaded, the main menu is initially played back (S31), and the user waits for the user's selection in that state. In the main menu, usually, a "1. Play movie" selection button for playing a title (eg a movie), a "2. Set up" selection button for calling up a submenu for selecting angles and subtitles or adjusting audio channels, and titles. A "3. Bonus" selection button is provided that calls a submenu for providing chapter information and other videos added by other creators. When "1. Play movie" is selected (S32) by the user, a movie is played back (S33), and when "2. Set up" or "3. Bonus" is selected, each submenu is played and then selected there. Performs a function of another selection button (not shown). After the reproduction of the movie, when the reproduction is completed (S34) or the main menu is called by the user during the reproduction (S35), the main menu is returned to wait for the next selection of the user.

Depending on the title (mainly in the case of a VCD title), instead of the main menu at the beginning, the movie may be played immediately as in the path 3-1 indicated by a dotted line in FIG. 3.

DVD, which is a representative multimedia, is a large-capacity medium capable of recording and playing high-quality video and audio, and its application is expanding not only as a movie or game title but also as an audio-oriented music video or learning program. In particular, as the growing enthusiastic people expect and the expectation increases, DVDs require development of various media contents, various menus, various events, and various playback methods.

However, according to the conventional plan playback technique described above, since a VCD or DVD title can only play one menu designated at the beginning of its driving, the producer himself or herself can designate one designated menu or one designated menu for one title on one media. It is true that the utilization as multimedia is low such that only video images are recorded.

In addition, according to the conventional plan reproduction technique, for example, in the case of a music video, many songs recorded in the same order every time the user was fed by the monotony, which did not give any more enjoyment.

SUMMARY OF THE INVENTION An object of the present invention is to randomly reproduce a video object which is playback data or a menu which provides information for selecting search and playback of the video data in the beginning or the middle of the media drive, prior to the conventional plan playback method as described above. This allows you to eliminate the monotony of the system playback operation by pursuing an unplanned, randomly selected playback, and seek freshness with unexpected images or menus each time. It is to provide a random playback method of the multimedia and its title that can enhance the function as a multimedia, such as providing a variety of.

The multimedia random play method of the present invention does not require special media format or hardware of a specific processing mechanism. That is, the system preferentially reads control data of a command sequence which generates a random number with the same probability using an authoring program command and recognizes a program chain which defines a reproduction of a target whose generated random number is the table of contents information. It can be implemented by storing in a designated position. Therefore, in the present invention, description of the data format of the media is omitted.

The basic operation of the system for the media title to which the present invention is applied is shown in FIG. That is, when the media title to which the present invention is applied is loaded into the player's drive (S21), the control function is read first to recognize the random function (S22), and the random play function is automatically performed according to the control data. It is to perform (S23).

Hereinafter, with reference to the accompanying drawings, it will be described a preferred embodiment of the method for random control of multimedia according to the present invention.

Example 1

Example 1 is as shown in Fig. 4, which is, for example, a movie title, having several movie screenings and a plurality of menus for each movie screening, with respective table of contents information 41 and 42 together. This is applied to the DVD title contained.

When the DVD according to the present embodiment is loaded into the player, at the beginning of its driving, according to the control data of the DVD, random numbers are generated by, for example, a random number generating program and correspond to the generated random numbers in the table of contents information 41. The menu of the table of contents is processed in the same manner as described below (one is the same), and one of a plurality of prepared menus is randomly selected (S41) and reproduced (S42). In addition, at the beginning of the driving, one of several prepared movies is randomly selected (S44) through the path 4-1 to be played back (S45) to immediately watch the movie.

In the initially played menu, as usual, the " 1. Play movie "selection button for playing a title (movie), " 2. Set up " for calling up a submenu for selecting an angle and a subtitle or adjusting an audio channel. Buttons and a "3. Bonus" selection button that calls up submenus to provide chapter information in the title and other video content added by the producer. When "1. Play movie" is selected by the user (S43), the movie introduced in the menu is conventionally reproduced, but in the present invention, one of a plurality of movie screenings recorded is randomly selected (S44) and played back. (S44) is to be. In other words, the viewer will be able to feel puzzled but interesting. If necessary, through the path (4-2) at the time of "1. Play movie" selection (S43), it is possible to play (S45) the movie introduced in the menu as in the prior art.

When the playback of a randomly selected movie image is completed (S46) or the user calls a menu (S47) during the playback, the main menu is randomly selected (S41) and the playback 42 is repeated as in the beginning of driving. do.

Of course, a corresponding menu may be reproduced through the path 4-3 for viewers who want to see the movie content or related video content watched now (S42). Even in this case, selecting "1. Play movie" on the menu is difficult to predict which movie will be watched by randomly selecting and playing the movie, which is still enough to cause some interest. Therefore, this embodiment will be a good way to enjoy omnibus movie format or movies of different styles.

In the meantime, when the user selects "2. Set up" or "3. Bonus" from the menu, the detailed description thereof is omitted. Naturally, the random reproducing method of the present invention may be added to various video objects provided by each submenu.

Example 2

Example 2 is shown in Fig. 5, which is for example aimed at an audio-oriented music video title that is slightly different from a movie title. The music video title contains table of contents information (51) defining the recorded music video images, and usually has a menu, in which the user selects the "1. Sequential Performance" selection button planned by a typical producer and the user. A new "3. Random Play" selection button is provided, along with a "2 Play by Table of Contents" selection button for searching, selecting and listening.

Conventionally, a monotonous plan play, in which a music video recorded at the beginning of its operation is performed in sequence from the first, is repeated for a general music video title, and the viewer is quickly distressed by predicting the next song to be played in advance.

According to the present exemplary embodiment, one of the plurality of music videos is randomly selected (S51) and reproduced (S52) at the beginning of driving. When the reproduction of one song is completed (S53), the above process is repeated. However, no one can predict when and when a song will be available.

When a menu is called up by the user (S54) and played back (S55) while playing a music video image, the user selects "1. sequence play" or "2. play by table of contents" provided on the menu (S56, S58). As shown in the related art, the performance can be audited in sequential performance (S57) or can be enjoyed through the selective performance of the desired music video (S59). You can enjoy by playing.

According to the present embodiment, since a different music video is displayed every time during the driving and even during the initial driving, it can give a fresh feeling of watching a new title. Therefore, the present embodiment may be usefully used where new video and audio are always needed.

Example 3

Embodiment 3, as shown in Figures 6 to 9, will be a way to fully enjoy the diversity, the greatest strength of multimedia such as DVD. In other words, it is a large capacity and can utilize the random function of the present invention to maximize the variety utilizing the various playback methods for the various contents.

In the multimedia for the present embodiment, theme contents information 61 for identifying the theme of each image is included along with various images such as movies, music videos, and games. In each theme, for example, "Theme 1 (movie)" has several menus along with several movie screenings as in the above-mentioned Embodiment 1, and "Theme 2 (music video)" as in Example 2 described above. It contains a number of music video footage and a menu. And "Theme 3 (Game)" has a lot of favorite game programs and one (or more) menus these days. Although only three themes are illustrated in the drawing, another theme such as a learning program may be added, and even the same movie image may be classified into different themes according to contents.

In the present embodiment, at the beginning of driving, one of the various themes that have been prepared is randomly selected (S61), and when "theme 1 (movie)" is selected (S62), the process proceeds to FIG. If "Theme 2 (Music Video)" is selected (S63), go to the process of FIG. 8 and listen to the music video. If "Theme 3 (Game)" is selected, go to the process of FIG. 9 and enjoy the game. To be. But no one can predict which theme will be chosen early in the run. Each video such as a movie, a music video, and a game classified by each theme is also reproduced by the random method of the present invention to further increase its variety.

7 shows a plurality of movie screenings and several main menus, which are generally the same as those of the first embodiment described above. That is, initially, one of several menus connected to several movie images belonging to the corresponding "Theme 1 (movie)" is selected at random (S71), and each main menu is selected (S72-1, S72-). Each main menu is reproduced (S73-1, S73-2, ..., S73-n) in accordance with 2, ...). Each main menu is provided with selection buttons of "1. Play movie", "2. Set up" and "3. Bonus" as described in the first embodiment. If "1. Play movie" is selected by the user (S74-1, S74-2, ... S74-n), the movie introduced from the menu is played (S75-1, S75-2, ..., S75). -n) That is, a little different from the first embodiment, it is possible to watch a movie provided in the main menu. Of course, as in the first embodiment, a function of randomly selecting and playing without applying to the main menu may be applied.

When the reproduction of the movie image selected in one of the main menus is completed (S76) or the menu is called by the user during the reproduction (S77), the user can return to the main menu for the first time or return to the initial state of driving. To go to a different theme and play music videos or games.

FIG. 8 is a case in which "theme 2 (music video)" is selected at the beginning of driving or by a user's menu call, and is substantially the same as in the second embodiment. Initially, the operation of randomly selecting (S81) and playing (S82) one of the plurality of recorded music video images is repeated each time the playback of one song is completed (S83), and the user calls a menu (S84) during the playback. If so, the menu is played back (S85). On the menu, the user can listen to the planned sequential performance (S87) or the selective performance (S89) according to the user selection (S86, S88), and then randomly listen to the selection (S90) of the random performance.

9 illustrates a case in which "theme 3 (game)" is selected according to the initial driving or a menu call of the user, and in this theme, various games can be enjoyed. Such game titles generally have a menu like a music video title. However, the present embodiment is only an example and is not intended to be limiting. Initially, the main menu is played (S91), and one of the games can be randomly selected (S95) through the path 9-1 so that the user can immediately enjoy the game.

The main menu is "1. Play game" that allows you to sequentially progress the games listed according to the table of contents information (91), "2. Game selection" to search by table of contents to enjoy the desired game, and "to enjoy randomly" 3. The selection button of "Random selection" is provided. When "1. Play game" is selected (S92), games sequentially recorded by the producer are sequentially played (S92-1), and "2. Select game" is selected. In operation S93, a desired game may be found and progressed in operation S93-1. On the other hand, when " 3. Random selection " is selected (S94), one of the randomly recorded games is selected (S95) and started (S96). When the game started by randomly selecting ends (S98), the game is asked whether to continue the game (S98) or another game (S99), so that the same game can be re-challenged or another game randomly selected can be enjoyed. The user may return to the main menu by calling the menu (S100) during the game. On the other hand, if you no longer want the game after the end of one game, you can return to the beginning of the drive to watch a movie or music video of another theme.

Example 4

The present embodiment is a video material that can be referred to as a special content of the present invention, in which a plurality of event videos and quiz videos connected to each event are included in the media together with respective table of contents information 101 and 102 as shown in FIG. 10. . Each quiz may be in a certain format, for example, common sense, questionnaire or nonsense quiz in each field, or may be a problem for learning according to an educational purpose. Of course, the questions for each quiz and their answer database (not shown) must be stored together on the media. The solution form presents some examples of solutions as optional information, such as selective problem solving, for example, to allow the user to select with the arrow keys on the remote controller.

That is, when an event of a video recorded by the user is selected (S101) while the media is being driven, one of a plurality of quizzes connected to the selected event is randomly selected and displayed (S102), and the user waits for the solution. Thus, when the user corrects the correct answer (S101), the selected event video object can be played back (S104) for viewing, and if it cannot be corrected, the user cannot view it. Even if the same event is selected repeatedly, it is not easy because different new quiz comes out by random.

The present embodiment may be effectively used to prevent minor access to, for example, educational programs for repetitive learning or adult videos that need to restrict viewing. Also, it can be applied in the form of sudden quiz for some main scenes of watching the movie or music video. Therefore, in the future, it may be possible to include adult and minor videos that could not be thought of until now in one media.

The random reproducing method of the present invention as described through the above embodiments is applicable to all media constituting a system capable of random control such as a DVD as well as a VCD. In addition, depending on the content it will be possible to more various random playback.

The present invention includes a variety of content in each field, such as video, music, art, education, etc. that can be shared in a large number of times in one multimedia, and always play a new, as if to see a different media every time, the conventional plan playback It can get rid of the eating habits and always give a fresh feeling by providing new images, as well as the excitement and pleasure of not knowing what will come out.

In particular, the present invention will contribute to the development of multimedia technology, such as inducing various content development by enhancing the function of the multimedia in a variety of playback methods.
