Description

Television {Television}

The present invention relates to a television, and more particularly, to a television having a local offline web server for initializing a web service and managing a plurality of contents provided through a web service in a multithread manner.

Today, the demand for information is soaring as to be called the age of information, and accessing the Internet, which is likened to the sea of information, acquiring necessary information and enjoying entertainment is becoming commonplace. In particular, access to and use of the World Wide Web (WWW) supporting text, music, or moving pictures in addition to characters is rapidly increasing. In addition, teletext broadcasting, which repeatedly provides various teletext broadcasting programs by multiplexing text and graphic information on one television broadcasting channel, can be used for news, weather forecast, television program guide, leisure information, sports, And so on.

On the other hand, Internet TV and IPTV (Internet Protocol Television), which provide bidirectional services between broadcasting stations and users, have emerged, unlike providing programs provided by broadcasting stations unilaterally to users.

Here, IPTV refers to a service that provides information service, video content, and broadcasting to a television receiver using a high-speed Internet, which is a type of digital convergence in that it is a convergence of the Internet and a television. It differs from conventional Internet TV in that it uses a television receiver instead of a computer monitor and uses a remote control instead of a mouse.

IPTV is not different from general cable broadcasting or satellite broadcasting in that it provides broadcasting contents including video, but it is a feature that it adds interactivity. That is, unlike a general airwave broadcast, a cable broadcast, or a satellite broadcast, a user can receive only a program he wants to watch at a convenient time.

An IPTV network that receives content through the Internet has a server and a client structure. A distributed web application program provided from a remote server does not respond quickly to a user's request. In addition, since a plurality of contents of a user-side apparatus (client) operate serially, management of the memory is inefficient and a phenomenon such as a screen stop may occur.

Therefore, it is required to provide an invention that exhibits a fast reaction rate even when a plurality of various contents are provided.

An object of the present invention is to provide a local offline web server for initializing a web service and managing a plurality of contents provided through a web service in a multithread manner.

The objects of the present invention are not limited to the above-mentioned objects, and other objects not mentioned can be clearly understood by those skilled in the art from the following description.

According to an aspect of the present invention, there is provided a television capable of receiving contents using an Internet protocol, the television comprising: a communication unit capable of receiving a plurality of contents; Generating a plurality of threads corresponding to each content to be assigned to each of the contents so as to process a job, generating a frame for each thread, and generating an image page for playing the respective contents in the frame Wherein the resource allocated to each thread is determined based on the type of each content.

In addition, in the television according to the embodiment of the present invention, the video page is an image page for simultaneously playing the respective contents on a web browser.

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

1 is a diagram illustrating output of contents provided from a remote web server on a web browser according to an embodiment of the present invention.

The remote web server 110 provides content using an RSS (RDF Site Summary) 111 or a web service 112. The content output apparatus according to an exemplary embodiment of the present invention includes a web browser 120 142, 143, and 144 to the at least one content provided from the remote web server 110 so that the content is individually output. Also, the main thread 145 is assigned to the user interface, and the contents can be controlled by the threads 141, 142, 143, and 144 according to user input.

In other words, at least one frame 131, 132, 133, 134 is provided on the web browser 120. The content output through each frame 131, 132, 133, 134 is transmitted via separate HTTP (Hypertext Transfer Protocol Request and HTTP response.

Here, the content output through a specific frame may be output through another frame according to the user's selection. To this end, information exchange between the threads 141, 142, 143 and 144 is accompanied by a thread management unit 290 for exchanging information between the threads 141, 142, 143 and 144.

In addition, a web server for initializing contents provided through the web service may be provided in the content output apparatus. Here, the web server is a web server provided on the offline side separately from the remote web server 110, which provides an advantage of efficiently managing a plurality of contents. That is, instead of directly outputting the content provided from the remote web server 110 through the frames 131, 132, 133, and 134, the provided web server generates new content for the received content, .

Here, the newly generated content can be changed in size and resolution to match the frames 131, 132, 133, and 134 with respect to the received content.

When receiving a JavaScript code from the remote web server 110 and performing a certain operation, it takes time to receive the JavaScript code. In addition, since the operation speed of the operation by the JavaScript code is generally slow, it is preferable to avoid the operation using the JavaScript code.

The image page having the frames 131, 132, 133, and 134 on the web browser 120 includes a Hypertext Markup Language (HTML) page, and the JavaScript code for composing the image page is transmitted from the remote web server 110 But may be provided internally. That is, the content output apparatus is provided with a minimum amount of JavaScript code for outputting the content, thereby avoiding the time required for receiving the JavaScript code and the delay in performing the job due to the use of the JavaScript code.

2 is a block diagram illustrating a content output apparatus according to an exemplary embodiment of the present invention. The content output apparatus 200 includes a content generation unit 210, a code conversion unit 220, a web server 230, a communication unit 260, A control unit 240, an input unit 250, a page generating unit 270, a thread generating unit 280, and a thread managing unit 290.

The communication unit 260 communicates with the remote web server 110 to receive at least one content. Here, the number of remote web servers 110 may be plural, and the communication unit 260 may perform communication with a plurality of remote web servers 110 at the same time.

The web server 230 initializes the web service provided from the remote web server 110. That is, the web server 230 establishes a session internally with the web browser 120 and exchanges HTTP messages.

When the web server 230 receives a HTTP request message from the web browser 120 while maintaining a session with the web browser 120, the web server 230 transmits the HTTP request message to the remote web server 110 and receives the HTTP request message from the remote web server 110 And transmits the HTTP response message to the web browser 120.

In initializing the web service, the web server 230 may initialize contents having at least one data format different from each other associated with the same topic. In this case, the same topic includes spatial information. When specific coordinates are input by the user, the web server 230 initializes the contents related to the coordinates from various remote web servers 110 based on the coordinates .

For example, when the user inputs coordinates such as latitude and longitude, the web server 230 receives contents such as news, traffic conditions, and weather corresponding to the corresponding area, or transmits television program contents It is possible to perform an initialization operation for receiving the data. Here, the data format of each content may be different, and may be data in a format such as HTML, extensible Markup Language (XML), or Microsoft Media Server (MMS).

In addition, the web server 230 may perform user authentication and user classification. The user authentication is used to determine whether the user is authorized or not, and is used to determine whether or not the content can be accessed by the inputted user information or the range of accessible content. For example, when the user authentication corresponding to the first user classification is completed, the web server 230 initializes only the contents for the news and the traffic situation When the authentication of the user corresponding to the second user classification is completed, only the contents for the TV program and the weather are initialized. When the authentication of the user corresponding to the third user classification is completed, The content can be initialized.

In other words, the user classification can be used as a criterion for outputting the content according to the user's taste, not simply the type of the output target content but also outputting the content according to the taste of various users. For example, when a plurality of contents are outputted first through a plurality of frames, an activated frame may be determined according to a user classification, a size of a frame may be determined, or a data transmission rate in each frame may be determined.

Information input by a user such as user information for user authentication may be input through the input unit 250. The input unit 250 may include a button, a wheel, a jog shuttle, and the like to receive information from a user. In addition, when the display unit (not shown) of the content output apparatus 200 provides the touch screen function, the display unit may serve as the input unit 250. For example, in the case of inputting coordinates, the user can input numbers or letters with a button or select a specific position of the display unit.

Here, the input unit 250 may be a single device by itself, for example, a wireless remote controller may serve as the input unit 250. [ That is, the user can input information using buttons and wheels provided in the wireless remote controller. When the inertial sensor is provided in the wireless remote controller, the user applies motion to the wireless remote controller and inputs information corresponding to the motion locus You can.

The content generation unit 210 generates new content based on the content received from the remote web server 110. At this time, the content generation unit 210 can generate the content whose size and resolution are changed according to the frame, and can change the received content with reference to the user classification.

Also, the content generation unit 210 can change the content in consideration of the network state, the usable capacity of the memory, and the processing capacity. For example, it is possible to change the size or resolution of the received content or to change the number of frames output per unit time in accordance with the network status, available memory capacity and computation processing capability.

Web services can be provided based on XML, Simple Object Access Protocol (SOAP), and Web Services Description Language (WSDL) protocols.

XML is a standard for W3C's text-based markup language. It can represent various expressions and data using tags in a different way than HTML. XML is useful for describing highly portable, structured data, and is often used to describe data. In particular, it is widely used in data formats that require interchange with messaging protocols.

SOAP is an XML-based lightweight protocol designed for exchanging information in a distributed environment. It defines a messaging protocol between a service user and a service provider. It also provides a standardized way to invoke remote services regardless of the platform, operating system, or programming language of the target service through XML-based messaging.

WSDL describes service interface information such as service connection information provided by a web service provider using XML, that is, message format to be exchanged during binding, and operation information provided by the WSDL.

Also, as described above, the content may be received in the MMS format. The code conversion unit 220 converts the web service code received in various formats into HTML code.

The thread generation unit 280 is responsible for generating at least one or more threads that are assigned to respective contents and process a job. That is, the work for each content can be processed by the individually provided thread, so that a parallel content output can be implemented.

In addition, the thread generator 280 may generate a thread for a user interface operation. A user may perform a network search using a user interface, and a thread for the user interface operation may be generated and operated by the main thread 145.

The thread management unit 290 manages the mutual operation among a plurality of threads. For example, the thread management unit 290 performs resource allocation in consideration of the types of contents to be processed on a thread-by-thread basis. Also, the thread management unit 290 may perform content switching between frames. For example, the first content being reproduced in the first frame may be reproduced through the second frame, and the second content being reproduced in the second frame may be reproduced through the first frame.

3 illustrates that each content is processed by a plurality of threads in accordance with an embodiment of the present invention. Each thread 141, 142, 143, 144, 145 generated by the thread generator 280 The operation for the corresponding content 310, 320, 330, 340 is processed.

Here, a thread that processes work for the user interface is created in the main thread 145, so that the work instruction input from the user is directly connected to the work process by each of the threads 141, 142, 143, and 144.

FIG. 3 shows that a plurality of contents 310, 320, 330, and 340 for a specific region selected by the user are reproduced. That is, the user can select a specific point 301 of the main screen 300 using the input unit 250. The coordinates of the selected point 301 are converted into latitude and longitude, and the content information corresponding to the converted coordinates Is extracted. For example, as shown in FIG. 3, information on RSS news, RSS weather, traffic conditions, and TV channels is extracted. The RSS news information includes a URL (Uniform Resource Locator) The RSS weather information includes a URL and a refresh cycle. The traffic situation information includes an MMS address, a frame rate, whether or not voice comments are supported, and metadata. The TV channel information includes an MMS address, a frame rate, Location, voice support, metadata, and tags. The content information may be stored in the content output apparatus 200 or may be stored in an external apparatus. To this end, the content output apparatus 200 may be provided with a storage unit (not shown).

As the content information is extracted, each thread reproduces the received content 310, 320, 330, 340 on the corresponding frame using the corresponding content information. The content information may be updated by the user or the remote web server 110.

Referring again to FIG. 2, the page generator 270 includes a thread-specific frame to generate a video page for reproducing content on the web browser 120. In generating the image page, the page generator 270 may insert the minimum JavaScript code provided for outputting the content into the image page to prevent the receiving time and the execution delay of the JavaScript code.

4 is a diagram illustrating that a web browser according to the embodiment of the present invention is composed of a plurality of frames. The page generating unit 270 includes a plurality of frames 410, 420, 430, 440) on the web browser 120. The web browser 120 generates a web page.

530 and 540 by a separate thread in each of the frames 410, 420, 430 and 440 as an image page is generated by the page generating unit 270, Is reproduced. Accordingly, even if a problem occurs in one of the contents 510, 520, 530 and 540 reproduced through the frames 410, 420, 430 and 440, the reproduction of the remaining contents can be guaranteed.

In addition, since the thread management unit 290 manages resources used by each thread, unnecessary resource occupation by each content is prevented, and more resources can be allocated to content requiring a large amount of resources.

On the other hand, the user can allocate more resources to specific contents according to his or her selection. Also, depending on the type of content, content requiring more resources may be generated. Accordingly, the thread management unit 290 can allocate more resources to the content. For example, contents such as traffic conditions and TV channels require a lot of network resources, memory resources, and computation processing resources, and the thread management unit 290 allocates more resources to these contents with reference to the extracted contents information .

2, the control unit 240 includes a web server 230, a communication unit 260, a content generation unit 210, a code conversion unit 220, a thread generation unit 280, a thread management unit 290, The input unit 250, the page generating unit 270, and the content output apparatus 200, respectively.

FIG. 6 is a diagram illustrating that each content is processed by a plurality of threads according to another embodiment of the present invention, in which news contents 600 provided through the RSS 111 are sorted and output according to categories .

6, the news content 600 provided through the RSS 111 is classified into a latest news field 610, an economy field 620, a science field 630, and a living / culture field 640 An individual thread corresponding to each category receives the first page of the category from the remote web server 110 and plays it.

Here, the contents 610, 620, 630, and 640 classified according to categories may be received from one remote web server 110 or from different remote web servers 110, and each content 610, 620, 630, 640 may be periodically updated.

FIG. 7 is a flowchart illustrating a process of generating a thread on a web browser according to a page code according to an embodiment of the present invention, and shows that a thread is created in C #.

First, when an element of the HTML page 700 is selected (S711), the C # function is called (S721). For example, a C # function is called when a user interface object such as an icon implemented by a JavaScript function is selected. Here, a C # function call can be understood as an initialization process for creating a thread using C #.

When the initialization process is completed, that is, when the thread creation function is called, an object is created by the thread creation function (S722). When an object is created, a method which is an operation function for the object is created. A thread object is created in the method (S723).

When the generated thread object is executed, the HTML page 700 is updated by the Control.Invoke method (S713). That is, the reproduction of the content by the thread is started from this time, and the HTML page 700 is executed in the multithread operation by JavaScript and C # (S712).

FIG. 8 is a flowchart illustrating a process of outputting content on a web browser according to a page code according to an embodiment of the present invention.

In order to reproduce the content, the HTML page 800 first makes an HTTP request to the web server 230 (S811). The HTTP request can be performed by JavaScript, ActiveX (ActiveX) or Web Control Windows Form.

As the HTTP request is performed, the web server 230 performs initialization for reproducing the content (S821). For example, it carries out operations such as user authentication or user classification, and allocates memory resources and network resources or generates image frames.

In response to the HTTP request, XML formatted content or RSS feed is supplied via the RSS 111 (S812), and the supplied content is input as a thread (S822).

As the XML formatted content is supplied, the HTML page 800 calls a function for converting the XML to HTML (S813), and the thread performs the conversion operation (S823). Extensible Style Sheet Language Transformations (XLST) or Cascading Style Sheets (CSS) can be used for conversion.

The converted content is outputted (S824), and the HTML page 800 reproduces the corresponding content in a specific frame using HTML, JavaScript, or the like (S814).

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
