Description

Broadcast Virtualization System

The following embodiments relate to a broadcast virtualization system, and more particularly, to a broadcast virtualization system that provides a real-time data service linked to a broadcast program regardless of a platform such as a TV, a PC, a mobile phone, and a tablet by using a virtual server.

Various convergence services are appearing according to the development of internet and communication, the development of digital video and smart phone. However, there are many problems in providing a data service that is linked to a broadcast program image in real time from a digital image. Despite the fact that the nature of the broadcasting industry should be able to provide services to many viewers at the same time, data development for interactive services was not compatible according to the type, performance, OS, and broadcaster of each user terminal. As the types of user terminals are diversified, there is an excessive amount of overlapping costs and time for data content development, and in reality, there is a limit in providing a linked service and generating revenue.

In addition, due to the nature of broadcasting programs that are usually organized at intervals of one week at a time, it was not practical to develop and apply a service suitable for all user terminals within a corresponding period. It was not possible to provide a bidirectional data service that is linked to (CF) in real time.

In order to solve this problem, a technology of virtualizing a server content and applying the same to a user terminal has appeared, but this is also not practical. In other words, the conventional broadcasting virtualization technology encodes the screen of the server into a video in real time and transmits it in the same manner as the existing broadcasting program transmission system, which is received through the tuner of the user terminal and decoded by the decoder and output to the screen. This is a method that requires a separate tuner and decoder for data broadcasting separately from a tuner and decoder for viewing a conventional broadcast program in a user terminal, and is not applicable to a user terminal having only one tuner and decoder.

In addition, in order to synchronize a broadcast program image and a virtualized data content image, the broadcast transmission system (MUX, etc.) is inevitably developed. Therefore, broadcasters using different broadcast transmission systems have limitations in simultaneous transmission. In other words, if the existing virtualization method is used in the terrestrial wave, the same service can be provided to all terrestrial viewers only if it can be linked with the broadcast transmission system used by each broadcaster such as different cable broadcasters A, B, C, and IPTV. Above all, since the virtual server system must encode the video (TS) corresponding to the broadcast video in real time, the number of concurrent users per virtual server system must increase rapidly, and even if there is no change in the screen, certain screens or blank data can be changed according to the video encoding method. Because of the need for continuous transmission, network usage also increased in proportion to the number of users, which was not practical in the current broadcasting environment where millions of viewers can watch simultaneously.

Hereinafter, embodiments will be described in detail with reference to the accompanying drawings.

The broadcast virtualization system includes a user terminal 110, a broadcast server 130, a schedule server 140, and a virtualization server 150.

The user terminal 110 may refer to any type of device capable of receiving a digital image and using a data content service linked to the digital image. For example, devices such as a set top box, a mobile phone, a smartphone, a tablet, a smart TV, and a navigation device may be used as the user terminal 110 in FIG. 1. The user terminal 110 may output the contents of the digital image and the data content to the display device 120. According to one side, the user terminal 110 may be a smart TV, in this case, it can be understood that the user terminal 110 and the display device 120 is integrated.

Here, the data content service linked with the digital video refers to a service that expresses the digital video and the digital content by synthesizing all the digital content such as text, image, video, application, file, and software into the digital video. According to one side, the digital contents synthesized in the digital image may be determined by the contents of the digital image and have a high correlation with the digital image. For example, if the digital image is to relay a baseball game, the digital content may be an advertisement for a baseball game that may be played on the user terminal 110. In addition, when the digital image is a music program in which a singer sings, the digital contents may be an advertisement for a sound source of a song sung by the singer.

The user terminal 110 may receive a digital image from the broadcast server 130. In addition, the user terminal 110 may receive schedule information on the data content linked to the digital image from the schedule server 140. According to one side, the schedule information is information including a condition that the data content associated with the digital image is expressed along with the digital image, and is information for providing the desired information to a desired target in a desired form at a desired time point. 140 may be a server that receives, generates, and stores schedule information, and transmits the schedule information to the user terminal 110.

For example, the schedule information may include a channel in which the data content is displayed, a time at which the data content is provided, program information in which the data content is displayed, URL information about the data content, an exposure position of the data content, an exposure frequency of the data content, and data content. It may include at least one or more of the information on the user terminal to be provided.

The user terminal 120 may display information indicating that data content associated with digital broadcasting can be provided with reference to the schedule information on the digital image. If the user determines to use the data content in response to the indication, the user terminal 120 sends a request for the data content service to the virtualization server 150.

According to another embodiment, the user terminal 120 may transmit a request for a data content service linked to digital broadcasting to the virtualization server 150 with reference to the schedule information. For example, the user terminal 120 may determine whether there is a schedule applied to a specific broadcast program or a specific channel. If there is a corresponding schedule and the time corresponding to the schedule, the user terminal 120 may transmit a request for a data content service to the virtualization server 150.

The virtualization server 150 is a server that executes data contents according to a request of the user terminal 120, generates the executed protocol data, and transmits the generated protocol data to the user terminal 120. Here, the virtualization server 150 may execute data content using a browser. In addition, the protocol data on which the data content is executed may be a screen of the virtualization server 150 in which the data content is executed. In particular, the protocol data on which the data content is executed may be generated by capturing an updated portion of the screen of the virtualization server by the browser of the virtualization server 150 executing the data content.

For example, when the data content is an advertisement linked to a digital image, the virtualization server 150 may load the advertisement using a browser and display the advertisement in the browser. As the advertisement is displayed in the browser, since the screen of the virtualization server 150 is updated, the virtualization server 150 may generate the screen of the updated portion as protocol data.

The user terminal 120 receives protocol data for executing data content from the virtualization server 150. The user terminal 120 synthesizes the received protocol data into a digital image and outputs the synthesized image. For example, when the data content is an advertisement linked to a digital image, the user terminal 120 may output the synthesized protocol data on which the advertisement is displayed with the digital image.

In this case, the user may select the advertisement output by combining with the digital image. The user terminal 110 may receive a user input and transmit the input of the user who selected the advertisement to the virtualization server 150.

The virtualization server 150 may play a video associated with an advertisement or load a webpage associated with the advertisement according to a user input. The virtualization server 150 may generate an updated screen as protocol data according to video playback or web page loading, and transmit the generated protocol data to the user terminal 110.

According to the embodiment illustrated in FIG. 1, even when the user terminal 110 is a low-performance device that can simply receive and output a digital image, and interpret and execute schedule information, the user terminal 110 may use the virtualization server 150 to perform digital operation. The data content service linked with the video can be used. In addition, the virtualization server 150 may provide the same service to all the user terminals 110 regardless of performance, platform, and the like of the user terminal 110.

In addition, the schedule server 140 may be used to define a condition (time for which data content is provided, a condition of a program included in a digital image, etc.) in which a data content service is to be provided, and thus, the existing broadcast transmission system or a user terminal may be limited. Irrespective of desired bidirectional content can be provided at a desired time, the bidirectional data broadcasting service can be provided in real time without any replacement or change to the existing broadcasting system.

In addition, the data content is executed using an internet browser, a separate application, etc. of the virtualization server 150, and the performance of the virtualization server 150 is improved by transmitting only a portion of the screen updated to the user terminal 110.

If the user decides to use the data content, the user may operate an remote controller or the like to transmit an input of using the data content to the user terminal 200.

The input signal transmitter 250 may receive an input from a user. When the input signal transmitter 250 receives an input meaning that the user will use data content, the data content request transmitter 240 transmits a request for data content linked with digital broadcasting to the virtualization server 290. .

Information indicating that data content linked with digital broadcasting can be provided with reference to schedule information is displayed. When the user selects the information, a request for data content is transmitted. Therefore, a request for data content is transmitted with reference to schedule information. You can judge.

The virtualization server 290 receives a request for data content. The request for data content may include information about data content to be executed by the virtualization server 290.

The virtualization server 290 may be equipped with a browser or a separate application capable of executing data content. The virtualization server 290 may refer to the request for data content and execute the data content using a browser or a separate application.

The virtualization server 290 generates protocol data on which the data content is executed.

The virtualization server 290 executes the data content 420 using a browser. Alternatively, the virtualization server 290 may execute the data content 420 using a separate application.

As data content 420 is executed, screen 410 of the virtualization server is updated. According to one side, the virtualization server 290 may generate the screen of the updated virtualization server 290 as the protocol data on which the data content 420 is executed as the data content 420 is executed. Alternatively, the virtualization server 290 may generate protocol data by capturing only the updated portion 430 as the data content 420 is executed in the screen.

The virtualization server 290 may transmit the protocol data on which the data content is executed to the user terminal 200.

In this case, the payment for the product linked with the data content may be performed using a smartphone.

According to one side, the virtualization server 600 may increase the processing speed by using the data cache. In this case, the protocol data cache unit 650 generates and stores the protocol data when the browser 630 executes the data contents before the request for the data contents is received from the user terminal. When the request receiver 620 receives a request for data content from the user terminal, the protocol data transmitter 640 transmits the protocol data stored in the protocol data cache 650 to the user terminal.

Using the virtualization server 600 described in FIG. 6, the user terminal directly receives the digital image. The virtualization server 600 executes the data content and transmits only the executed result to the user terminal. Since the virtualization server 600 does not receive the digital image, the virtualization server 600 does not need to update the screen every moment. In addition, when the virtual server 600 does not change the screen of the browser, the virtual server 600 may not generate the protocol data. Therefore, the frequency with which the virtualization server 600 generates the protocol data is greatly reduced. In addition, the virtualization server 600 may generate protocol data by capturing only an updated portion of the screen of the virtualization server 600 by executing content data. Therefore, the size of the protocol data is greatly reduced, and the network from the virtualization server 600 to the user terminal can be efficiently used.
