The present invention relates to a video object information providing technology, in particular, by providing the object information data stored in the area information on the object such as goods, art, terrain, etc. appearing through the video screen is stored in the video data, the user When the object is selected through the present invention, the present invention relates to a video object information providing technology capable of displaying detailed information or displaying a web page that provides information about an object by accessing a corresponding web site.

Conventional advertising through video or broadcast content is performed by inserting an advertisement in a specific portion of a video player, inserting an advertisement on an initial screen of a video, or displaying a text-based advertisement at the bottom of a video screen. .

As such, the video containing the advertisement is distributed by a content provider (CP), which is limited in the amount of content, and it is difficult to utilize already distributed content.

In addition, since the advertisement is explicitly exposed through the video screen, there is a problem that may cause a rejection of the advertisement of the video viewer.

Recently, you can see products in placement (PPL) ads that use props from movies or dramas to promote their products. In other words, it is a kind of indirect advertising that can raise the brand image on the company side and receive the amount of money required for the broadcast production on the broadcast side.

Although various products are introduced in the video contents through these PPL advertisements, the PPL advertisement alone cannot present more specific information about each product, and only the appearance of the products is presented in a range that does not interfere with the contents of the video contents. There is a limit.

It is an object of the present invention to select information on an item set in advance by a content provider when the item is selected through a mouse click or a touch screen input in the screen without separately searching for information on a specific item appearing in a video screen. It is to provide video object information providing technology that can display or access the website.

According to a first aspect of the present invention, there is provided a method for providing video object information using region information, comprising: (a) providing video data; (b) object information data including one or more object region information and link information corresponding to the object region information, which are arranged according to the sync information and the sync information synchronized with video data in time and define a specific region on the screen for a predetermined time; Receiving step; (c) playing the moving picture data; (d) calculating one or more regions defined on the screen from the sync information and the object region information on the basis of the playback point of the video data; (e) detecting an external event for the calculated area; And (f) providing an execution according to the link information corresponding to the object region information for the external event.

The video object information providing method using the area information according to the second embodiment of the present invention is arranged according to (h) the video data, the sync information and the sync information synchronized with the video data in time, and the specific area on the screen for a predetermined time. Receiving object information data including at least one object region information and link information corresponding to the object region information by streaming; (i) playing streaming received video data; (j) collecting and configuring streaming received object information data; (k) calculating one or more regions defined on the screen from the sync information and the object region information on the basis of the playback time of the video data; (l) detecting an external event for the calculated area; And (m) providing an execution according to the link information corresponding to the object region information for the external event.

According to the present invention, it can be easily distributed by modifying a subtitle file having a small capacity, such as an SMI file, and can be easily applied to existing multimedia contents that are already widely spread.

In addition, when applied to product advertisements appearing during the broadcast, the screen does not specify that the advertisement exists in the video content, thereby eliminating viewers' rejection of watching the video. You can get detailed information immediately by selecting a product.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an overall system configuration for implementing a video object information providing technique using the area information of the present invention.

The first embodiment of the present invention relates to the case where the moving picture data 451 and the object information data 452 are provided in the storage medium 45 in the moving picture reproducing apparatus 40. The second embodiment relates to the moving picture data. And it relates to the case of receiving the object information data by streaming from the multimedia content providing server 20. Therefore, in the case of the first embodiment, the present invention can be implemented without the intervention of the multimedia content providing server 20.

The web site providing server 10 may have its own URL address so that other computers or terminals connected to the network 30 such as the Internet may access through the URL address. The web site providing server 10 may provide an advertisement web page including information on various products, and may provide a shopping mall for purchasing products. In addition, an advertisement or a shopping mall may also provide a web page that provides contents on a specific theme.

The multimedia content providing server 20 holds video data in advance and provides streaming or broadcast data broadcast in real time.

In addition, the multimedia content providing server 20 may pre-create the object information data in the form of the present invention for each video data, and may provide the video content playback device 40 in the form of streaming or download.

Here, the object information data includes sync information that is synchronized with video data in time, thereby bringing the effect of being reproduced together when playing the video data. Therefore, when the caption information is arranged according to the sync information and included in the object information data, the caption corresponding to the playback scene of the video data can be displayed on the screen.

In addition, the object information data includes one or more object area information arranged according to the sink information. The object region information defines a specific region for a predetermined time period of the running time of the video data. For example, when a specific item to be defined as an object appears in the video data, an area of the corresponding item may be defined and included in the object area information during the time when the specific item appears. The easiest example is to define the object area through the coordinates, width, and height of the objects that appear on the screen.

In this case, not only one object area but several objects may be defined at the same time. That is, when several important objects appear on a screen, it is possible to define a region for each object separately.

The object information data includes link information in addition to sink information and object area information. The link information may include a detailed description or advertisement text of the object in the form of text or an image, or a URL address that may lead to a web page providing information about the object.

The video player 40 may play video data, and has a function of recognizing the content of object information data according to the video data. The video player 40 is a concept including a personal computer, a PDA, a PMP, a mobile communication terminal, and the like, in which a video player is installed. The video player 40 may be provided from the outside through an update function for recognizing object information data. .

The data transmission / reception unit 41 accesses the web site providing server 10 through the network 30 to receive web page data, or receives video data and object information data from the multimedia content providing server 20. The received video data and object information data are stored in the memory 43, and in the case of permanent storage, they are stored in the storage medium 45.

The control unit 42 reproduces the moving image data stored in the memory or pre-stored in the storage medium through the data transmission / reception unit 41 and outputs it to the screen display unit 46. In addition, the object information is collected and reconstructed to collect the object information data, and the area defined on the screen is calculated based on the playback point of the video data.

When a mouse click or a touch screen input input through the external input unit 44 occurs within the previously calculated area, a detailed description of the object is output on the screen or connected to a URL address through link information of the object information data. Display the web page on the screen.

The memory 43 loads data stored in the storage medium 45 so that the controller 42 can process the data. Video data and object information data downloaded by streaming are once stored in the memory 43. In the case of a video broadcast in real time, it serves as a kind of buffer in which a certain amount of broadcast data is stored before being displayed on the screen.

The external input unit 44 receives a control signal that can be selected and influenced by an external user with respect to an image displayed through a screen, and corresponds to a mouse input or a touch screen input. The user clicks an object on the screen with a mouse or provides a signal input to the touch screen to the controller 42.

The storage medium 45 means a permanent data recording medium such as a hard disk or a memory card. The video data 451 and the object information data 452 may be provided from a device directly connected to the video player 40 such as a diskette, CD, DVD, or USB line, and may be streamed or downloaded and stored through an external network 30. It may be.

The video data 451 generally refers to video data in a compressed format such as avi and mpeg.

As described above, the object information data 452 includes sync information, object region information, and link information of the video data, and may include subtitle information in some cases.

When the video data is converted into a video signal through a process such as decoding through the control unit 42, the screen display unit 46 displays it on the screen. If the object information data including the caption information is provided, the caption is displayed on the screen. In addition, when a user selects an object displayed on the screen and inputs it with a mouse click or a touch screen, detailed information of the object included in link information of the object information data is displayed on the screen according to a command of the controller 42.

2 illustrates an example of selecting an object through a video playback screen.

A user who views a video through the video player may select an object of interest while watching the video.

When the user clicks on [Example 1] on the screen, if the mouse clicked area is registered as the object area information in the frame currently playing in the object information data (eg SMI file), the video player recognizes it and Launch the browser to the URL address stored in the link information of the object area information.

When the mouse is clicked on [Example 2], if the area selected by the user is registered in the object information data, the video player recognizes it and the detailed description of the object stored in the link information of the corresponding object area information is stored in a specific position of the video player. Output

When [Example 3] is clicked, if the area is not included in the object area information defined in the current frame, an information window is displayed to indicate that there is no detailed information or the click is ignored.

3 is a flowchart illustrating the overall operation of the method for providing video object information using region information according to the first embodiment of the present invention.

First, object information data is generated (ST10).

The object information data is composed of a format generated by extending files such as SMI, SSA, ASS, etc., which are mainly used as existing subtitle files, and a video reproducing apparatus capable of recognizing such object information data should be separately provided.

The object information data includes sync information, object region information, and link information about specific video data, and may additionally include caption information.

(1) Sync information refers to information synchronized with video data in time. In other words, the total running time of the video data is divided and stored in very fine time units.

(2) The object area information is arranged according to the sink information to define a specific area on the screen for a predetermined time. That is, time information about when information is activated and when it is deactivated is arranged based on the entire running time of the video data, and the information includes information about a location and an area on a screen of a specific object. For example, the running time from 3 minutes and 20 seconds to 3 minutes and 40 seconds may be set such that an area of (X, Y, Width, Height) on the screen represents a specific object area.

(3) The link information includes processing contents when a user input occurs in an area on the screen according to the object area information. That is, a detailed description of the object is recorded so that when the user input occurs, the description of the object can be displayed on the screen. Also, since the URL address is stored, when the user input occurs, the user accesses the corresponding website. You can also display the web page in a browser.

(4) The caption information contains captions for the video data. Like the object area information, the caption information can be arranged according to the sync information so that the caption can be seen and disappeared for a predetermined time.

The process after the object information data that satisfies the above conditions is generated is as follows.

First, moving image data is stored in a storage medium in the moving image reproducing apparatus (ST20). Unlike the second embodiment, the moving picture data in the form of a complete file is stored in a storage medium such as a hard disk or a memory card.

Then, the object information data for the video data is stored (ST30).

After the moving picture data and the object information data are provided in the moving picture reproducing apparatus, when a moving picture reproducing command is generated by a user's operation (ST40), the process of decoding the moving picture data stored in the storage medium and restoring the image signal and the sound signal. After that, it starts to output through the screen and the speaker (ST50).

At this time, the object information data corresponding to the video data is read out to calculate an object region synchronized with the video data currently being reproduced from the sync information and the object region information in the object information data (ST60). If the caption information is included in the object information data, the caption is displayed in a partial region of the screen based on the playback time of the video data currently being reproduced from the sync information and the caption information of the object information data.

If an external event such as a mouse click or a touch screen input is detected in the calculated object region (ST70), the contents of the link information connected to the object region information are recognized and appropriate processing is performed accordingly (ST80). ).

That is, if the detailed description of the object is stored in the link information, the description of the object is displayed in a part of the screen.

In addition, if the URL address of a specific web site is stored in the link information, after recognizing the URL address and accessing the web site corresponding to the URL address, the web page is displayed on the screen by executing a browser.

4 is a flowchart illustrating an overall operation of a method for providing video object information using region information according to a second embodiment of the present invention.

The first embodiment corresponds to a case in which the video data and the object information data are already provided in the form of a complete file in the video reproducing apparatus, while the second embodiment corresponds to the case where the video is reproduced by streaming in real time as the broadcast data. .

That is, the video data packet is received through streaming, stored in a memory buffer, and the received data packet is restored in real time and reproduced. At this time, the object information data is also received by streaming data in the form of divided into packets, three specific methods of receiving the object information data in the packet will be described in more detail with reference to FIG.

Since the second embodiment is not significantly different from the first embodiment except that data is transmitted by streaming, the operation process common to the first embodiment will be briefly described.

First, object information data is generated as in the first embodiment (ST110), and the contents of the object information data are the same as in the first embodiment.

Then, the video player receives the video data and the object information data by streaming (ST120). A process of streaming two types of data into packets will be described in detail with reference to FIG. 5.

After that, when a video playback command is generated (ST130), a part of the video data is restored from the currently received packet data and played back (ST140).

In addition, the streaming received object information data is collected and partially or completely restored (ST150).

Subsequently, when a user input occurs in the object area defined in the object information data based on the playback time point of the video data currently being played, a process of displaying the detailed object information or displaying a web page by accessing a URL address (ST160). ST180 is the same as the process ST60 to ST80 described with reference to the first embodiment of FIG. 3, and thus, reference may be made to FIG. 3.

5 is a diagram illustrating a method of receiving video data and object information data by streaming according to the second embodiment of the present invention.

FIG. 5A illustrates a case in which the object information data is completely received before the video playback is performed, instead of the object information data being transmitted in real time streaming during the video playback.

In other words, when the size of the object information data is not relatively large compared to the video data, the transmission time does not take very long. Therefore, when the object information data corresponding to the entire playback time of the video data is received in advance, the object information data is more easily handled. can do.

In addition, the object information data may be provided from a provider that generates and distributes only the object information data through a route separate from the provider of the video data.

5B illustrates a case in which packet data including video data is received and object information data included in a partial region of the received packet data is extracted.

In other words, the object information data is transmitted by using a partial area of the video packet data little by little, and when the remaining area such as the header area of the video packet data is used, the object information data can be transmitted together.

In this case, of course, after receiving the packet data, the process of extracting and restoring the object information data should be performed.

FIG. 5C illustrates a case in which the video data and the object information data are received by the same streaming, and the video data packet and the object information data packet are separately provided from the point of view of the streaming provider.

In other words, the streaming receiver needs to separately distinguish whether the received packet is video data or object information data and store it separately. After separating and restoring each of the packets, the video data must be reproduced and the object information data must be recognized.
