Referring to FIG. 6, the determination of whether to play the secured content may be performed through the following procedure.

The application unit 120 may receive a virtual URL (S30).

Subsequently, the application unit 120 may determine the error by checking the input virtual URL (S31).

As a result of the determination in S31, when there is an error in the virtual URL, the application unit 120 may determine that the input virtual URL is not played and skip the content (S32).

As a result of the determination in S31, when there is no error in the virtual URL, the application unit 120 may check the content URL (S33).

Subsequently, the application unit 120 may determine the type of the identified content URL (S34). In this case, it may be determined whether the type of the content URL is simple or media information (S34).

Subsequently, the application unit 120 may determine whether to play through the Simple Checker or the Media Info module according to the type. First, when the application unit 120 is a simple type of the content URL, the application unit 120 may determine whether the content URL can be played back using the simple checker (S35).

Subsequently, when it is determined that the content URL is playable, the application unit 120 may store the information about this in the database 130 (S36).

On the other hand, if it is determined that the content URL that can not be reproduced as a result of S35, it can skip the content URL (S32).

Simple Checker may only be available for content that uses the HTTP protocol. The method of checking whether the “Content-Type” of the HTTP connection response header is the Media content type can be applied. This method has the advantage of being fast. On the other hand, the accuracy is low, it is difficult to determine the existence of the audio, video stream.

On the other hand, if it is determined in step S34 that the media information (Media Info), the application unit 120 may determine whether the content URL can be played back using the open source media information (Media Info) (S37).

Here, even if the type is set to Simple Checker, if the HTTP protocol is not used, it is possible to determine whether the content URL can be played using the Media Info module.

As a result of the determination in S37, when it is determined that the content URL is playable, the application unit 120 may store the information about this in the database 130 (S36).

On the other hand, if it is determined that the content URL that can not be played back as a result of the determination in S37 (S32) it can be skipped.

In this case, the use of the Media Info module has a high accuracy and an advantage of determining whether an audio or video stream exists. On the other hand, there is a drawback of being slow.

A development environment of a module for determining whether to play a content URL may be as follows.

Eclipse Java EE IDE for Web Developer v4.7.1a

Java 1.8

-Media Info v18.03.1

An execution environment of a module for determining whether to play a content URL may be as follows.

-Using Media Info: Windows 7 or later & Java 1.8

7 is a diagram illustrating an example of a channel edit window. 8 is a diagram illustrating an example of utilizing a Contents Delivery Network (CDN) service. 9 is a diagram illustrating an example of an IPTV channel server web site. 10 is a diagram illustrating an example of generating a channel list in Json format.

7 to 10, the IPTV system may provide a web-based free content database management module. The functions and features of IPTV Channel Server are as follows.

The IPTV Channel server may perform free content URL list management. The free content URL management and the URL list can be provided to a playback device such as a designated set-top box. In fact, the upgrade of the commercialized quad-core based IPTV set-top box (Smart6.1) provided software can provide a list of Special IPTV sections. List of Special IPTV Sections Lists are available online from the IPTV Channel Server.

The IPTV channel server may perform transcoding. The IPTV channel server receives a stream from the free content URL. Real-time transcoding may be performed based on the input free content URL, and the converted video stream may be provided to a terminal of an individual user through a CDN service.

In the case of a channel, the URL accepted by the playback device may be the present Server system. In the case of transcoding, the load of server resources (CPU, memory) and network resources can be an issue. You can select the Passthrough option, which can mean the option to output the incoming stream as it is. By using this option, the first CPU load can be reduced, the URL of the second original source stream can be hidden, and the third one source source server can be greatly reduced. Third, there is an advantage that a plurality of users can be connected to the original source server to prevent the interruption in providing the image due to the load. Using this Passthourgh option can reduce CPU load, but there are still network load concerns. In this case, using a commercial CDN service can solve these problems.

An implementation environment of the CDN service may be as follows as an example.

-Operating System: Ubuntu Linux 16.04

Web Service Engine: nginx with rtmp module & php7.0-fpm (FastCGI Process Manager) socket

Transcoding tool: ffmpeg package

Transcoding can be done by a web service calling the linux command in the ffmpeg package. In a Ubuntu Linux environment, the worker process of nginx, the web server, does not have root privileges, so you cannot run ffmpeg under the given conditions. Therefore, it can be set to grant command execution permission to the worker process execution user (eg www-data). The default run options for ffmpeg are:

ffmpeg -i <source URL> <video, audio conversion options> <target URL>. In this case, the target URL may configure a Media Resource Locator (MRL) with the -f flv option and rtmp, an Adobe protocol. In this case, the URL provided to the user may be configured as rtmp: // <hostname> / ....

As shown in FIG. 8 and FIG. 9, the IPTV channel server may manage the free content channel. Content information may be managed in units of channels. The channel may consist of a channel name, a URL, and a thumbnail URL. The thumbnail URL is the location of the icon image, which can appear as a separate item on the screen the user sees along with the channel name. In operation, the thumbnail URL must be separately obtained by the administrator. In requesting the full channel list from the set-top box by the POST method of http, the combination of ID and password can be supported by base 64 hashing method. The return may be a method of returning a text script in JSON format as a result. The IPTV channel server may provide a channel list to the terminal of the user using the JSON format. An example of a program coating for creating a channel list is shown in FIG. 10.

The server including the content securing application of the present invention and a method of driving the same may collect source content registered in the source manager at a predetermined time using a contents sync service. In addition, content may be classified by category to generate a content list, and the generated data may be stored in a database. In addition, a content list may be obtained through a source base, and the obtained content list may be updated.

In the above, embodiments of the present disclosure have been described with reference to the accompanying drawings, but a person having ordinary knowledge in the technical field to which the present disclosure belongs may change the present disclosure without changing the technical spirit or essential features thereof. It will be appreciated that the present invention may be practiced as. The above described embodiments are to be understood in all respects as illustrative and not restrictive.
