Description

Intelligent Video Browsing System {INTELLIGENT VIDEO BROWSING SYSTEM}

The present invention relates to an intelligent video browsing system that provides content replay using highlight information and metadata.

Most broadcast programs are produced in series and broadcast at designated times. In the case of a user (viewer), even if it is his favorite program, it is difficult to watch the program without missing every time. In addition, the broadcast viewer may not remember the contents of the previous program broadcast after a certain time even if the program he watched. The user has a demand for summary information of all the pieces of a program that is broadcast periodically, but the broadcast receiver or the multimedia content browsing device up to now have not provided such a function. If a function of summarizing a previous program related to a program that is currently desired to be viewed is provided, the user can be greatly helped in watching the sequel without saving the previously broadcasted program (the first part) and can save the viewing time.

Video highlights are provided to provide summary information for such multimedia content. Providing video highlights allows the user to understand the broad summary without having to watch the entire content and to use it as a preview to decide whether to view the entire content or not.

Typically, such video highlights are obtained by extracting only the main scenes from the entire content and editing only the selected segments to create one independent content. The video highlight generation method is mainly a static method and a dynamic method.

The static method is to physically edit and store the highlight content offline, and to service the highlight content when the user's highlight request occurs. The dynamic method is only information on which part of the entire content is to be played when the user requests a highlight request. When a description is separately provided, the highlight is provided by sequentially reproducing segments described in the highlight description information in the original content by using the highlight description information related to the original content when the user plays the highlight.

In general, the static method requires a lot of storage space, and the dynamic method requires only a small amount of storage space. 1 illustrates a physical method and a logical method among highlight information presentation methods. The highlights described using the physical highlight information description method are serviced through a static method of playing the highlight file generated offline from the beginning to the end, and the highlights expressed by the logical highlight information description method are described in the highlight description information. It is served using a dynamic method of continuously playing back the segments.

Referring to FIG. 1, in the case of a physical description method, a highlight file (new content) is constructed using segments H1, H2, H3, H4, and H6 to be used in a highlight file, and the file is played when a highlight is requested. In the logical description method, the information on the segments to be reproduced when highlighting is requested in the entire content is made in a separate table, and the segments (H1, H2, H3, H4, H5 and H6) are reproduced sequentially to provide highlights.

These video highlights are generally provided by the media creator. Recently, even if a media producer does not provide highlight information, research is being conducted to provide a highlight function. In general, the automatic highlight providing method generates highlight information by selecting key segments of a story development by describing shot segmentation technique, shot clustering technique, event detection technique, and genre-based knowledge information, and describing information about them. Current systems are different from the highlights provided by the producers, but they have been performing in several genres as a function of summarizing the entire contents.

On the other hand, in a client-server relationship such as a video server, video highlights can be used as a preview function in content selection. The client device does not need a storage device for content storage, and the media file and highlight information are stored on the server. When a user accesses a video server using a client device, receives content information, and requests highlight information on desired content, the user may service the highlight using an association between the program stored in the server and the highlight information.

Recently, PVR (Personal Video Recorder), which can record and play simultaneously, has been introduced. The PVR is basically equipped with a hard disk, and the hard disk is used to store recording content or temporarily store some video data for time shift. Using a PVR set-top box, users can use instant replay or forward skip while browsing content, and enjoy high-speed fast view and low-speed playback. In recent years, a storyboard interface using segment skipping, video skimming, and keyframes using index information is performed by simultaneously indexing content recorded in the set-top box. Research is being conducted to enable various nonlinear video browsing such as interfaces.

As described above, the multimedia content browsing system or the display system provides a highlight function for video summarization or browsing. With the provision of the highlight function, metadata is described in multimedia content.

Metadata generally refers to data about data. The multimedia content itself is data, and information about such multimedia content is defined as metadata about a multimedia program. Metadata for multimedia content includes a producer, a director, a character, a plot, a production date, a broadcast date or a release date, plot information, and background information. This metadata enables the search for multimedia content, so that the user can easily search for the desired content or selectively view the desired content in the vast multimedia content database. Therefore, studies to standardize such metadata are actively in progress. In a digital TV environment, such metadata may be transmitted in the form of an EPG (Electronic Program Guide).

The present invention provides a service providing method and browsing system for providing an automatic summary function for programs associated with a selected program to a user using a multimedia content database, highlight index information for the multimedia content, and metadata for the multimedia content. An object of the present invention is to provide a method of constructing the highlight playback information.

Still another object of the present invention is to allow a user to play content that the user originally wanted to watch when playback of highlights for a program associated with the selected program is completed.

It is another object of the present invention to automatically control the highlight level of content associated with a selected program according to production date information or broadcast date / release date information.

Another object of the present invention is to release and broadcast previously among programs associated with the program selected by the user when the user explicitly requests to view a specific program or a request for re-viewing programs related to the specific program. If there is a produced program, a list of related programs is constructed, and the user can provide a review function of a related program before viewing the selected program by receiving a simple input of the user.

It is still another object of the present invention to recognize associations between programs by using program metadata including information on IDs, producers, producers, production dates, broadcast dates, and the like. It is to provide automatic replay function by using relevant highlight information.

It is still another object of the present invention to provide a summary of a program in a short time using a condition such as time information about a program or a user's viewing when a multi-level highlight information is provided, and a program to provide a more detailed summary. In this case, when the user requests to summarize the content within a specific time, it is possible to provide a summary that can be browsed within a specific time using time information, whether the user is watching.

Another object of the present invention is to provide an intelligent video browsing system that can operate in a client-server environment and can be implemented in a digital set-top box having a storage device.

In order to achieve the above object, a method of providing a video browsing service according to the present invention comprises constructing a list of programs related to the selected program using metadata of a program selected for browsing or highlighting multimedia content and a metadata index for the programs. Presenting information about the programs to the user; Inputting information on whether the highlight is reproduced from the user with respect to the presented information, a desired length of the highlight, etc., to configure highlight reproduction information according to a user's request, and reproducing the highlight according to the configured highlight reproduction information; Characterized in that comprises a.

A video browsing service providing method, a system, and a method of configuring highlight playback information according to the present invention made as described above will be described in more detail with reference to the accompanying drawings.

2 is a diagram illustrating an example of a method for describing a program metadata index. Metadata generally refers to metadata about multimedia content provided by a program producer or a provider, and includes a producer, a director, a character, a plot, a production date, a broadcast date or a release date, a plot information, and background information. The metadata index of the present invention includes, in such metadata information, media link information for directly or indirectly indicating a storage location of actual media, and highlight index information indicating highlight information.

Let's look at how to describe this highlight information. As described above with reference to FIG. 1, the highlight information includes a physical description method and a logical description method according to a storage type, and can be divided into a first level highlight and a multilevel highlight providing method according to the number of provided versions. The present invention will be described based on a multi-level highlight information description method using a logical description method that is more efficient and can cope with various applications.

Different people have different comprehension and users have different time to spare, so in some cases they can ask for a three-minute highlight and in some cases a ten-minute highlight. While physical descriptions can be cumbersome for storing different versions of highlights, logical descriptions have little storage or administrative burden for storing multiple versions of highlights. Accordingly, a multi-level highlight information description method and a highlight service method are proposed.

3 is a diagram illustrating a multi-level highlight information description method. The multi-level highlight information description method using a logical method defines a plurality of summary levels, and assigns one or more highlight segments to the summary level. The highlight segment has segment information, and the segment information indicates the start and end positions of the segment in the original content file. In FIG. 3, a total of n summary levels are considered to be defined. In the example of FIG. 3, the highlight of the k-th level is designed to include the highlight of the k-1 th level. That is, the highlight of the kth level is serviced by continuously reproducing the highlight segment of the k-1th level in the order of time including the highlight segment designated in the kth level (Dependent Structure). This structure has the advantage of efficiently managing data, but to obtain the k-th level highlight information, it is necessary to access all the highlight information from 0 to k-1.

In some cases, the multi-level highlight information may use a method of designating segments to be directly reproduced at each level. In this method, there is data duplication, but only the k-level data needs to be accessed to obtain the k-th highlight information (Independent Structure). 3 is an example of a highlight description method using a dependent structure.

4 is a diagram illustrating a method of generating a highlight from the highlight information defined by the highlight information description method of FIG. 3 on the time axis. As described above, the highlight H _k of the k-th level includes the highlight H _{k-1 of the k-1} th level, and the highlight H ₀ of the 0 th level is the shortest version of the highlight.

A method of providing an automatic replay service of the present invention using the above-described highlight information and program metadata will be described step by step.

If the user has requested browsing for a particular multimedia content or explicitly requests a highlighting request of an associated program for a particular multimedia content, in the first step the system will display the metadata of the selected program and the metadata index for the stored programs. Use to sort the list of related programs.

The metadata is a material describing the producer, the director, the character, the plot, the production date, the broadcast date or the release date, the plot information, the background information, etc., and the metadata index includes metadata of programs recorded by the system; Data stored for each program including data specifying a storage location of the program and highlight information for the program.

In this step, the user may implicitly input the highlight request of the associated program to the system by selecting a program by channel selection or program designation.

Next, in a second step, the system presents the user with information about programs in which highlight information exists among the programs in the list of programs related to the selected program. In this case, the highlight information may be information described by the multi-level highlight information description method as described above, and the information on the programs in which the highlight information exists is presented to the user.

Next, in the third step, the system receives information on whether to play the highlight, the desired length of the highlight, etc., from the user and configures the highlight playback information according to the user's request. The method of constructing the highlight reproduction information will be described later in detail. Next, in the fourth step, the system reproduces the highlight according to the configured highlight reproduction information. When performing the highlight playback in this way, it is preferable to first play the highlights of the previously aired / released content on the basis of the respective airing date / release date of the highlights of related programs.

In a fifth step, the system may further perform the step of sequentially playing the originally selected content after the highlight playback.

Through this process, the user can get a great help in watching the originally selected content by previewing the highlights of the programs related to the desired program.

The method of configuring the highlight reproduction information mentioned in the third step will now be described. The video highlight playback information is composed of weights that are differentially applied according to user preference / unfavorability information of a multimedia content, broadcast date / release date information of a program, and whether a user views a corresponding program, and highlights the related programs according to the weight. It is characterized by setting the length of each differently.

That is, in the method of configuring the highlight playback information that meets the user's needs of the service providing method of the present invention, additionally, the user's viewing pattern is used or whether the user has previously watched the related content in advance, and the airing date / release date is from the present time. A comprehensive intelligent use of how old it was can provide a more intelligent automatic summarization.

Information on whether the user uses the viewing pattern or whether the user previously viewed the related content may be automatically obtained by using the user authentication process. That is, when a user logs in using an input means to the system or recognizes the user to the system using a device such as a smart card, the user may use a viewing pattern or a viewing record of the corresponding user. In the third step of the service providing method of the present invention, a method of using information regarding a viewing pattern of a user, whether the user has previously watched related content in advance, and how long the broadcast date / launch date was from the present time point will be described. Same as

The system may obtain preference and / or non-preferred information for the user's program from the user's viewing pattern. In this case, in configuring the highlights for the related contents, different highlight weights are applied to the programs that the user prefers and the programs that are not, so that the level of highlights is provided for the preferred program. Differentiation strategies can be used that provide shorter highlights.

That is, in determining the highlight playback length for each related program, the playback length is determined by using the user's preference / non-preferability information for the related program.A higher user's preference gives a higher weight and a lower or less preference. The higher the degree, the lower weight is assigned, so that the higher the preference, the longer the playback length, the lower the preference, and the shorter the playback length.

In addition, the system may provide more user-adjustable highlighting by providing different levels of highlighting for the programs in the related program list depending on whether the content has been previously viewed or not. In other words, by providing a highlight of a short length for content that the user has already watched, and providing a highlight of a longer length for content that is not viewed by the user, a highlight having a high user satisfaction can be provided within a limited time.

In other words, assign a low weight to content that the user has previously watched, and assign a high weight to content that the user has not watched to reduce the playback length for the content previously watched by the user, For content, the playback length is increased.

The system also uses metadata information about how far the air date / launch date was from the current time point, and automatically applies different weights to the programs in the related program list, taking into account the air date / release date, to automatically highlight the level of the highlight. Can be set. That is, in consideration of the association with the selected content, the closer the temporal program is, the higher the association is. Thus, a more detailed highlight may be provided. Otherwise, a short highlight may be used. In other words, if the broadcast date / release date of the content is closer to the broadcast date / release date of the originally selected content, the higher weight is assigned and the lower weight is assigned farther, so that the broadcast date / release date of the related program is close to the broadcast date / release date of the originally selected content. Increase the play length, and move it farther away.

The summary of the highlight weight setting method described above may be expressed as Equation 1 below.

W_i = alpha × P_i + beta × V_i + gamma × D_i ~~ (alpha + beta + gamma = 1)

W _i is a highlight weight for the i-th content in the related program list, and P _i is a value related to the user's preference / unfavorability. V _i is a value that is determined depending on whether or not the user has watched the content. Generally, V _i is assigned a high value when the content is not watched. D _i relates to the difference between the broadcast and the release date between the program to be watched and the i-th content of the list. The highlight total reproduction time L of the related programs for the selected content to which the weight is applied is determined using Equation 2. In Equation 2, n denotes the number of contents existing in the related program list.

Highlight (W _i ) means a highlight playback time for the corresponding content (i-th content present in the related program list) when the weight W _i for the i-th content present in the related program list is considered. The larger the weight, the longer the highlight information is returned, and the smaller the weight, the shorter the highlight information is returned.

5 is a diagram illustrating an embodiment of a service providing method in the case of providing a highlight replay function for a related program of the present invention.

When the user selects a specific program or selects to view the related program highlight of the specific program (S501), the system constructs a related program list using the metadata of the selected program and the stored metadata index (S502). Receiving a play request input (S503), by setting the highlighting weight for each related program by inputting the airing date / release date information and the information on whether or not to view the programs present in the user's viewing pattern and the related program list, Based on this, the lengths of highlights to be reproduced by each related program are set (S504 and S505), and information about segments to be reproduced is reconstructed to reproduce highlights of the corresponding length.

In FIG. 5, when the user wants to watch 99 programs, the highlight length is defined by the highlight weight setting method using 94 to 98 programs in the related program list, and 94 to 98 times. A total of six minutes of highlights up to the time is reproduced (highlight reproduction mode) (S506). When the highlight play mode is terminated, the program plays 99 times of content that the user originally wanted to watch according to the setting, so that the user can quickly browse the related programs and watch the content that originally requested viewing (S506). If such a service method and system are implemented in a system such as a PVR, if a user uses the time shift function automatically while content is being played in the highlight mode, the user can normally view the content after broadcasting the highlight.

That is, when using the method of playing the highlight of the relevant program for the content being broadcasted, the program originally selected during the highlight playback is simultaneously saved using the time shift, and after the highlight viewing mode is ended and the normal viewing mode is switched to Simultaneously recording and playing back the originally selected program.

6 is a diagram illustrating a service providing method of an intelligent video browsing system that provides a function of replaying related contents using highlight information and program metadata of the present invention.

When a user selects a program or explicitly re-views the related program highlights, the system receives information about the selected program (S601), and matches the metadata of the selected program with metadata indexes stored in the storage space. A related program list is created (S602).

If there is a relevant program in the match step of S602, branch to S604 , otherwise branch to S608 to play the originally selected content. If the related program exists in the match step of S602 and branches to S604, the system notifies the user that there are related programs, and obtains information about whether to view the related program highlight and the desired highlight length (S605).

If the user requests viewing of the associated program highlight, the process branches to S606; otherwise, branches to S608 to play the originally selected content. When the user requests to watch the related program highlight and branches to S606, the system reconstructs the highlight information that meets the user's request (S606), and plays the highlight of the related programs using the reconstructed highlight information (highlight playback mode: S607). . When the highlight play mode is completed, the system automatically plays the originally selected content (S608). If such a request occurs during live viewing in the PVR system, the original content is time shifted while step S607 is performed.
