The present invention relates to an on-demand video set-top box with a scrap analyzer. More specifically, the present invention relates to a text-based bidirectional communication and service method and an additional device in a VOD set-top box.

In the conventional method, the realization of the interactive service uses a method of embedding and delivering the service content in one track of video in a format written for the interactive content, and collecting the user's response by using a phone separated from the screen. In the present invention, one user device can easily interoperate with each other through the analysis module and the additional input device to play the contents of the interactive service, execute the service contents, and receive and transmit the information through the additional device, such as a simple website link. Beyond the functionality, it is possible to add new functionality to the user device or instruct it to perform a complex task.

In a conventional computer program method, a specific time must be waited for a predetermined time after a program is executed, and a specific operation must be performed at a predetermined time, or a condition is continuously monitored, and a predetermined operation must be performed when a condition is matched, inserted into a subtitle file or broadcasted. The program cannot be delivered to the set-top box by including it in a character broadcast and transmitted, and the execution of the received program must include a process performed by the user to achieve the desired purpose. It cannot be applied at the same time in the process of receiving a service or broadcast, and it is not possible to add temporary new functions to the set-top box, and even a program for several different operations can be collectively performed by combining them into one execution program. Differences and the like in the sense There is a tooth.

Conventional interactive services are largely divided into a type of broadcast quiz program in which a specific content is serviced by a user's request, such as video on demand, and a user participates in solving a problem. The present invention does not correspond to the function of the former VOD, which is already utilized, and relates to the latter interactive service format.

In the conventional method, a telephone number or the like is written on the broadcast screen and a call is made using the ARS (auto answering service) to make a call while watching the broadcast screen, and the answer is input using the number buttons of the telephone. Two-way service was implemented by inputting contents in one track of video data (tracks added in addition to video and audio tracks) and inputting multiple choice answers using the numeric keys of the remote controller. In the case of a set-top box with a web surfing function, a method of encouraging visits to the website and linking and processing them was used.

Example 1 Construction of a Character-Based Bidirectional Script

Character-based bidirectional scripts consist of a common set of characters and instructions based on natural language, including the same functions as components of a computer programming language, such as declarations / conditions / repeats / functions / displays / inputs / arithmetic. Unlike the general computer programming language, the script is configured to determine the execution and interruption of the script according to service conditions such as content playback time / playback condition / absolute time before the program is executed.

Scripts can be created and stored in the form of text files or real-time typing, which can be included and delivered regardless of the existing format in web servers, DB servers, tracks of video content, subtitle files, text broadcasting files, and message services. Can be.

The transmission means may be the Internet, a text transmission system of airwaves / satellite / cable broadcasting, a storage medium such as a DVD / VCD / HDD, or the like, and a combination thereof may be used.

As shown in FIG. 1, a script interpreter for receiving and performing a bidirectional script includes a mounting processor configured to mount the received script on a set top box; An execution condition determination processing unit for determining and executing the execution time and the immediate execution of the loaded script; A script execution unit for interpreting the contents of the script and performing as defined; A display display unit which superimposes and displays on the screen of the main function of the set-top box in order to visually display the execution result of the script; A set-top box controller configured to operate in place of all operations that can be operated by the user in the set-top box according to the result of the execution; A service control unit operating on behalf of a possible service that can be operated by the user in the set-top box according to the result of the execution; A function reassignment key processing unit that defines a function according to the execution result; An execution result transmission unit for transmitting the execution result to a server or the like according to a defined content; Heterogeneous device control unit for directly controlling the home appliances connected to the set-top box; It is composed of a heterogeneous device control signal transmission unit connected to a home network and transmitting a control command.

FIG. 2 is a flowchart illustrating the operation of the script interpreter of the present invention, and FIG. 3 is a flowchart illustrating the operation of the script parsing processor.

According to FIG. 2, the script is checked in a script parsing notification waiting state, and in the case of a script, the contents of the delivered script are overlaid. Then, it checks whether the execution of the script meets the condition, and if so, executes the contents of the passed script multiple times. Checks whether the execution condition of the script is met during execution or after execution, and if it meets, unloads the script and maintains waiting for script derivation notification.

According to FIG. 3, when the set-top box performs a unique function and recognizes a script parser, it checks whether the script is a script and, in the case of a script, transmits the recognized script contents to the script interpreter.

Example 2 Operation of Character-Based Bidirectional Script

Actions possible with the present invention can be made variously through the device of the user side according to the content of the script. Therefore, the scope of the action depends only on the function and performance of the user-side device, and the scope of the action is not defined by the interactive content. The present invention can be implemented in various devices such as digital broadcasting set top box, Internet set top box, digital home appliance, home or industrial robot, industrial digital equipment, VOD set top box. The digital home set-top box with broadcasting reception, VOD, internet surfing, home shopping, home network, and home server functions will be given as an example.

9A to 9G illustrate examples of the present invention applied to a movie subtitle file and transmitted, and a configuration example of a script showing the effect of the present invention.

An example of movie subtitles in the standard subtitle processing format. This example is a subtitle of the movie "007 Another Day". In the embodiment, the indication of the time such as "Start = 30770" in the subtitle means 30770 ms, but the example of the time indication 100 "Start = 30" in the script is after the movie starts. 30 seconds. Its unit can be arbitrarily adjusted, but in the present embodiment, unless otherwise specified, "second" is used as a unit.

The first script embodiment of FIG. 9A is an embodiment in which the current time is displayed on the upper right side of the screen until the end of the movie is pressed until 30 seconds after the start of the movie. In many cases, a time display function is adopted in a set-top box, but this is a program having a time display function in the set-top box in advance, and a display / non-display is selected. However, in the embodiment of the present invention, the time is set in the set-top box. In the state of not having the function to display the time display function by the time display script included in the 007 movie subtitles, that is, a new function is temporarily installed (until the end of the movie). Therefore, even if the same time display function according to the present invention various functions according to the contents of the script, such as Korean time or international time, 24 hour display or 12 hour display, time display from the start time, remaining time from the start time to the appointment time display I can have it.

The second embodiment of the script 101 of FIG. 9C is an example of stopping a movie that is being played with content that is executed for about 502 seconds starting at 6497 seconds after the start of the movie and ending at 6999 seconds, and randomly outputting six advertisement images. In general, in order to insert an advertisement in the middle of watching a video in an on-demand video, an advertisement image must be edited and inserted into a video image to make a content file. Alternatively, the content may be divided into 1,2 parts from the beginning, and then an advertisement may be forcibly inserted after the first part and before the second part. However, in the former case, it becomes cumbersome to re-edit the advertisement video after each time for changes such as the termination of the advertising contract or the insertion of a new advertisement. The video should be divided into two parts. Therefore, both the former and the latter offer the same on-demand video service, but if the paid video is viewed at once without ads, and the free video must be viewed at the same time, the content is changed accordingly. It is inconvenient and inefficient to be stored in the server divided into two for non-advertising (paid). If you want to divide the price and the number of ad impressions into three forms of paid, reduced, and free, the same content will be needed three times.

However, according to the present invention, as shown in the embodiment of the second script 101 of FIG. 9C, it is possible to determine whether the condition is just passed, how many advertisements are displayed by the script, and so on. It is possible to implement various types of video services on demand.

The embodiment of the third script 102 of FIG. 9E is an example in which four contents are posted on the screen, and after the current content is finished, the next content is moved out to the menu and selected without finding a list. For example, if you watched the news of economic news "The price is not serious," the traditional method would be to look at the menu list and select it after watching the news. However, if you use this method, after the first news, you will see a list of consecutive news on the screen, such as "Iraq farewell farewell ceremony" and "Distortion of Goguryeo, China". According to the case of the first news that chose economic news, it is possible to list only the economic news such as "New York stock market rebound" and "Return to flat apartment in Seoul Gangnam area".

As such, the application examples that can be implemented using the results of the present invention as in the actual embodiment are posted. As described above, the action of the script is arbitrarily made according to its contents, and the operation of the set-top box can be controlled by using the same. Therefore, the following application example is only a representative content and does not mean a limitation of the function.

Example 3 Quiz Program with Users

In the current broadcast, the quiz program in which the user participates is inputting the correct answer using only the ARS phone. In the present invention, a bidirectional script for a quiz is made by integrating on-demand video or broadcast, and the user can participate in the quiz in various ways through the operation thereof.

1) Promote the user participation quiz program through subtitles. This can be done by using the forced control function of the set-top box on the user's side as shown above to display the promotional caption at the appropriate position regardless of the contents currently used.

The content of the script

<Script Start = now>

</ Script> (This example is a brief description of how various scripts are presented to illustrate the operation of the present invention. The actual script contents may vary in form.)

The content of this script is "Sends a message to all users and displays the message twice at 30 seconds in a scrolling manner at the specified coordinates. ○ Press the button to select Join to open the Mpeg4 VOD file from the VOD server and share it with the VOD file. Run the provided script immediately. " Therefore, regardless of the content currently being watched, the ○ (example-red color button) button is selected and the content to be automatically watched is replaced.

2) When the quiz program is displayed, the key for explanation and answer of the quiz is displayed on the screen according to the order of progress of the video, and if the input is made within a predetermined time, the script records it on the server for collecting the quiz answers through the Internet.

3) The final result is shown to each user along with the result video and the user's choice is made so that the explanation of the wrong answer can be seen.

(Example 4) situation propagation or announcement propagation in emergency

It is also possible to notify users of emergency situations or post announcements by using the forced control of the user set-top box and the interactive script function. At this time, it was possible to inform the contents by grouping at the national or regional broadcasting station level according to the existing method, but according to the present invention, the user can be determined by continuously performing / stopping based on the ID of the set-top box and the result of initial script execution. It is possible to deliver a message by grouping in various ways, such as a small group of apartment complexes or a group according to the user's inclination.

1) In case of emergency: By disregarding the video currently being watched by the unconditional execution command of the script delivered as a message, superimpose the message on the emergency situation or by superimposing the message on the video and generating the sound of warning messages and coping methods. Can be presented through In this case, as described in the foregoing description, the grouping may be presented only to the corresponding user in various ways.

2) Dissemination of Announcements, etc .: Disseminate the necessary announcements within a specific group, such as the impending meeting time in an apartment, and induce access to contents that can be described in detail. At this time, if the set-top box has a function linked with a remote metering sensor of electricity, water, and gas, the scripting language informs the user when the contents of the notice indicate the meter reading time and the metering sensor linked to perform the remote meter reading function immediately. It may be able to read the value of and send it to the specified remote metering record server, and at the same time, recommend the user to reconfirm.

4 is an exemplary TV screen to which the present invention is applied to a quiz program.

In addition, in the conventional method, when the power of the set-top box is turned off, the transmission thereof is performed by broadcasting, and thus it is not possible to check whether the delivery is successful. In the present invention, even when the power of the set-top box is turned off, the objection is transmitted with the script. By having the server receive the presence or absence of reception, the server can identify the user who has been delivered and repeatedly propagate it until it is delivered. 5 is a TV screen according to an embodiment of the present invention applied to a known radio wave.

Example 5 Adding a New Add-on

The bidirectional script delivery and execution method according to the present invention includes not only the representation of characters but also the representation of graphics, interworking with a database server, control of user devices such as set-top boxes, data exchange and control with devices interworking with a home network, and the like. have. Therefore, this method allows the example set-top box to perform broadcasting and on-demand video viewing as its main function, and by receiving interactive scripts, it can perform functions not built into the original set-top box like a Tetris game. . In the conventional method, such additional functions could be added from the set-top box purchase or upgraded, but the method according to the present invention is always added or deleted, temporary use, and main service through simple selection. VOD or broadcast viewing) can be equipped with additional functions that operate in conjunction with.

Example 6 Multi-angle Video Viewing

In the case of a DVD has a function to watch the video taken from different angles by the user's selection. That is, for example, the video viewed from the criminal's point of view and the video viewed from the police point of view can be viewed. However, in VOD (on-demand video), the multi-angle image viewing function could not be accommodated due to the problem that the amount of data to be transmitted is greatly increased to transmit two or more images at the same time.

In the script function of the present invention, all functions that can be operated by the remote controller can be processed in the script, and thus can be implemented using the same. For example, if you handle the same situation manually, "If you want to watch the VOD at the police point for about an hour with two VOD contents of the criminal point of view and the police point of view, then watch the current point with the remote control. If you stop the video of the current police point, go out to the menu, select the content of the criminal point of view, skip the 1 hour watched by pressing the FF (Fast Forward) key, and then watch the multi-angle video. Will produce the same result. " If this process is actually performed by the user, the process is not only annoying, but also cannot be executed accurately and quickly. However, as a result of the present invention, the multi-angle VOD viewing function can be implemented by processing the process through a script. At this time, the user only manipulates one remote control key (key assigned to change the viewing angle change function) to instruct batch processing, and the operation described by the script is automatically and quickly processed to change the viewing angle on a DVD or the like. Effect.

Example 7 Home Shopping and Information Service Implementation

Even in the case of set-top box with internet surfing function, in order to use home shopping and information service, it is a conventional method to embed a web browser and access the site through the web browser. In this case, only remote control is impossible and a mouse or equivalent positioning device should be used. In addition, embedding a web browser in the set-top box requires additional permanent storage and temporary memory, which can increase the price.

According to the present invention, even in such a case, it is possible to post a product using the control of the interactive script and the VOD function, and to process the selection of the product, the selection of the quantity, the payment, and the like, so that home shopping can be performed without a separate web browser. In the same manner, it is possible to perform various information services such as weather, stock price, and neighborhood shopping mall information.

In addition, by using the interlocking with the broadcast, the home shopping broadcasts the unidirectional home shopping contents in the conventional manner, and orders through the remote control, such as by sending a script matching the home shopping broadcast, compared to processing the order over the telephone, etc. It is possible to process.

(Example 8) Automatic posting additional function and information service

By using the proposed actions and setting up a more complex bidirectional script syntax, the set-top box can be used as an information publishing device in the example of a broadcasting and VOD set-top box.

When the user is not watching a particular broadcast or VOD, using a script that operates in such a condition includes operating the following additional functions.

1) Electronic aquarium function: The script is made of digital graphics, and the user can make a user's display device like an aquarium by using a virtual reality function operated by a program to give a visual effect.

2) Electronic album / frame function: It is similar to the electronic aquarium function, but it functions as an electronic picture frame by replacing various pictures in a stationary form and posting them on the screen. In this case, if a user or a person related to the user puts a picture or a family picture on the server, the set-top box may download and post a picture registered on the server through the interpretation of the script. This function can be used as a function for a child who is studying abroad to register a photo in the local area, and the parent of the home can see the newly added photo on the frame without any special manipulation.

6 is an exemplary diagram of a presentation executed in a set top box.

3) Presentation function: Like the example of the electronic album function, it combines the images registered on the server with additional articles, downloads them and posts them to the video device, and the contents can be replaced by the remote controller. Can perform the presentation function. This has the advantage that the existing method does not require the operation of the PC compared to the presentation using the PC, and can present immediately on the large display without preparation.

4) Personal assistant service: Connect to PC through general web server, select interests and necessary information, enter schedule, and set-top box will be automatically turned on at a fixed time or by user's operation It can be downloaded through script or delivered in real time and posted on the screen. According to an embodiment of the present disclosure, only economic news among the news of the day that is mainly interested in the screen may be selected and displayed in a VOD manner regardless of the broadcaster, or the news of a specific broadcasting station that is currently being broadcast may be displayed. By dividing the screen like this, one side posts the video information, while the other side posts the current stock price, today's weather, and today's schedule of the stock of interest. The configuration of such a screen can be arbitrarily configured by a user or a service provider, and the contents of the configuration are made through a bidirectional script that is a result of the present invention. In addition, interactive scripts can be embedded in set-top boxes, or can be downloaded on demand instead of embedded.

5) Use in education and news broadcasting: In the example of conducting VOD online education through video education materials, the service provider checks the completion status of the user by inserting a script or tests or quizzes to check the result of the education. It can be used to present and grade accordingly. Also, when arranging the fragmentary training videos in a row, at the end of the training, the next training contents are posted on the screen and the user selects them. I can eliminate it. The same applies to the VOD-type viewing of a news broadcast, so that after viewing a news item, the related news or news content of the day is listed and selected without moving to a menu.

7 is a diagram of a preferred embodiment in an on-demand video set-top box.

On-demand video set-top boxes have finished listing English training videos at the end of the video.

Such a method is only a part of an example showing the use of a script, and is not necessarily limited to VOD. Existing broadcast and VOD functions may be simultaneously performed, or the existing broadcast method may be applied to a channel change.

8) Use as a home network server: According to the present invention, this can be applied to a home server in a home network configuration, and can be utilized for various digital home appliances or home robots. According to the configuration of the script can be used to control the digital devices in the home by transmitting the configuration of the pre-made script to the home server of the home via the Internet, a mobile phone, a general telephone, and the like. This method does not include only predefined functions in the control of digital devices, and provides a way to easily change the control method from time to time according to need or replacement of digital devices. Compared to the need to upgrade in order to respond to this, there is an effect that can be applied immediately and does not require an upgrade.

As described above, the functions of the present invention are not limited to specific functions, as shown in the embodiment of the additional function or information service, and are characterized by the flexibility of being made in various forms according to the configuration of the script.

In the above-described embodiments of the present invention, the input device used by the user may be a remote controller, a keyboard, a mouse, or the like. In this case, a message must be displayed in order for the user to select the execution result of the script displayed on the screen. Assuming that a user is watching a drama of interest via VOD or broadcast, a service provider wants to sell an actress's necklace online in a show that has a prominent place on the screen. Displaying a message may be offensive to the user.

At this time, if a small icon representing home shopping using the script of the present invention is expressed in color, and the actress exposes the product for a while, the exposure may be reduced for a while. On the contrary, the service provider has a merit that it does not weaken the effect of the advertisement by prominently exposing the icon to the matching scene through the colored icons. If the user is interested in purchasing a necklace, they will press a button of the corresponding color or icon on the remote control. In this case, the script may pause the VOD watched by the user's selection, move to the VOD screen where the description and purchase of the product proceed, and return to the location of the drama after home shopping is finished. If the user is watching a broadcast other than the VOD, it is possible to post a caption and a picture about the introduction of the product and how to purchase the product at a suitable position from the time when the user presses the button.

The input device of the present invention has a number of keys in addition to the number keys and up, down, left, right, Play, FF, Rew in such a situation or a situation such as quiz, so as to perform various operations depending on the result of the script execution Describes input devices with defined function reassignment keys.

In other words, a certain key defined by the program operates according to the existing method regardless of whether the input device is a keyboard or a remote control, but the function of a specific key can be defined as needed through a bidirectional script, and the function of such a key is provided to the user. The way to post is to assign an icon shape to a key or to assign a specific color to let the user know which key to use regardless of the type of function.

In the previous necklace shopping example, if the icon posted on the screen is in the shape of ▩, or if the usual shape of the shape is red, the other items on the same screen may be colored in yellow, blue, or other patterns. In addition, by placing a red, yellow, and blue button on the remote control or a key shaped like a ▧▨▩, the user naturally recognizes the key in response to the posted message.

The same red key leads to the purchase of a necklace here, but other content allows you to choose a travel product, even within the same content, which leads to the purchase of a different product, in a quiz, or in a home appliance control or information service. It can then be programmed in real time by a script to perform different actions.

8 is a diagram of a remote controller to which the additional input device of the present invention is applied. This is an example of a remote controller that uses 4 color keys as a function reassignment key.

Some of the results described in the configuration and operation of the present invention can be implemented by a general program method, but for this purpose, a program must be built in the set-top box so as to perform the functions in advance. However, in the present invention, only the interpreter of the script language is built in the dictionary, and detailed configuration and operation are always newly generated when the set-top box receives the script from the server. Therefore, functions and actions not described in the configuration and operation can be changed indefinitely depending on who composes the script.

To those skilled in the art, the present invention is not limited to the above-described embodiments and the present invention may be embodied in other forms without departing from the spirit of the invention. All design changes made within the scope of the claims and equivalents are considered to be included within the scope of the present invention.

According to the present invention, it is possible to control the operation of a new program according to time and condition without executing it in advance, and to operate the script as long as it matches the built-in analysis module regardless of the hardware / software environment of the user device. It can be delivered through text-based scripting, non-encrypted or non-encrypted text-based scripting, subtitle files, subtitle tracks, or messaging services. Means for superimposing the operation of the device on the user's side with voice / video and the like, and reading the user's response based on the contents of the expressed interactive service to control the user's device or transmit it to the server for reflection. In addition, a remote control / keyboard / mouse with a key capable of reassigning a function to replace a complicated operation with a few keys added to a keyboard / mouse by adding a few keys to a simple remote control to read a user's response. Additional functions such as additional input devices and new functions using only interactive scripts can be added. The present invention has the effect of controlling the control of other devices, scripts and user devices to perform complex operations by delivering only an overview of the operations.
