The content service apparatus 10 can provide a hosting service that provides the content by either a download method (referred to as a content download) or a streaming method (referred to as a content stream) according to a client's selection. The content uploaded to the content service apparatus 10 by the client can have various formats. However, the format of the content that can be streamed by the streaming server 22 described below is limited. Therefore, among the contents uploaded by the client, it is necessary to change the format to a streaming format which is inappropriate for streaming, and the process of changing the format of the content to be suitable for streaming may be defined as trans-coding.

The content service apparatus 10 can preview the content for the content when the client requests the content preview to check the dictionary information about the content to be downloaded or streamed.

The content service apparatus 10 filters content that is required to be transcoded among the contents uploaded from the client 30 and requests the content management apparatus 20 to transcode the content determined to be necessary for transcoding by filtering , And stores the uploaded content and the transcoded content in the content storage 12.

When content downloading, content streaming, or content previewing is requested from the client 40, the content service apparatus 10 transmits the location information (URL: Uniform Resource Locator) of the content to be downloaded or the content stream, Information to the client (40). The content preview may be provided by streaming.

Here, the clients 30, 40, and 50 may be terminals of a computer, a smart phone, a tablet PC, a mobile communication terminal, or the like, which the user uses, and may be a program operating in the user's terminal. The client 30 of this embodiment can be defined as uploading the content and the client 40 can be defined as using the Internet repository service for content download, content streaming or content preview on the uploaded content, The client 50 may be defined as a terminal of an advertisement company.

The content management apparatus 20 can provide a management function for contents in various formats managed in a web site operated by the content service apparatus 10. [ The content stored in the content repository 12 of the content service apparatus 10 may include meta data, and the meta data may include information about a title, a production date, an actor, a supervision, etc. of the file. The content management apparatus 20 can provide a management function by which the client 40 can easily find the content by a desired condition (title, actor, director, etc.) by utilizing the metadata.

The content management apparatus 20 receives the transcoding request of the content from the content service apparatus 10, receives the original file of the requested content to perform transcoding, stores the transcoded content in the content storage 12 And generates location information of the transcoded content and provides it to the content service apparatus 10. [

When the advertisement content is uploaded from the client 50, the content management apparatus 20 classifies the advertisement content into categories and stores the classified advertisement content in the advertisement content storage 24, and transmits the content 40 to the client 40 in any one of content download, content streaming, And inserts the advertisement content into the content provided to the user. When inserting the advertisement content into the content, the content management apparatus 20 can select the advertisement content to be inserted into the content by matching the meta data of the content with the category information of the advertisement content or the meta data of the advertisement content itself.

Referring to FIG. 2, the content service apparatus 10 includes a content service server 11 and a content repository 12.

The content service server 11 provides a variety of convenient functions such as uploading / downloading of contents, creation and modification of contents and folders, moving, deleting, copying, creating a notepad, and easy automatic backup in the Internet environment.

The content service server 11 stores the uploaded content in the content storage 12 from the client 30 and filters content that needs to be transcoded for streaming among the uploaded content, Requests the content management apparatus 20 to transcode the content, and receives location information (URL) from the content management apparatus 20 in which the transcoded content is stored. For example, when the content is uploaded, the content service server 11 filters the content through extension filtering, and transmits the content location information and metadata to the transcoding unit 21 for the content requiring transcoding for streaming, Content that is usable without transcoding is uploaded to the content storage 12 without being transcoded, and the location information is managed.

The content service server 11 provides the client 40 with location information (URL) of the requested content upon receiving a request for downloading the content, streaming the content, or previewing the content from the client 40. [

The content service server 11 can set the preview to preview only a predetermined section of the content or to view the content only for a predetermined time or for a predetermined period regardless of the section, If you do not meet these rules, you can stop previewing.

In addition, the content service server 11 collects playback information (playback frequency, playback time, sharing status) of the shared content and user information (information provided to the server from the client such as browser version and OS version) can do.

The content storage 12 stores the original file of the content uploaded from the client 30 for the content download service of the content service server 11 and stores the original file in the form of a source file determined to be unnecessary to be transcoded by the content service server 11 And transcoded content of the content.

1 and 2, the content management apparatus 20 includes a transcoding unit 21, a streaming server 22, a real-time advertisement management server 23, and an advertisement content storage 24.

The transcoding unit 21 receives the transcoding request of the content from the content service server 11, reads the content corresponding to the transcoding request from the content repository 12 and performs the transcoding, And transfers the location information of the transcoded contents to the content service server 11. [

The transcoding unit 21 may include a transcoding manager 211 for managing overall transcoding and a plurality of transcoders 212 for performing substantial transcoding.

The transcoding manager 211 may be configured to allow the transcoding manager 211 to distribute or prioritize the transcoding job in response to a transcoding job request from a plurality of transcoders 212 to smoothly support the preview service And may include a transcoding priority algorithm that provides preferential inferencing previews and sequentially provides a high-quality preview. For example, the transcoding manager 211 may determine a processing object to be processed first among the processing objects to be processed, and when the upload content from the client 30 is transcoded during a specific period, Request) or to prioritize or lower the priority of transcoding according to the content metadata or the client 30 via specific rules (such as metadata or filename rules). Therefore, the present embodiment can support the streaming service for content preview and content streaming by appropriately distributing the traffic generated by the transcoding unit 21 itself or the traffic generated by the transcoding.

The transcoder 212 substantially performs transcoding of the selected content in response to the control of the transcoding manager 211. [ The plurality of transcoders 212 may be configured to be selectively activated in response to the control of the transcoding manager 211. [ The transcoder 212 may provide a translation function such that the network, resolution, processor capabilities, user interface, etc., may be commonly used by different clients 40.

For example, the transcoder 212 may proceed in low-definition 640 * 360 or 426 * 240, 300-500 Kbps, and high definition 960 * 540 or 640 * 360, 500-800 K bps for mobile in MP4 format of H.264, Transcoding can be done for low quality 640 * 360 or 960 * 540 for PC, 500 ~ 1M bps, and high definition 1280 * 720 >> 800K bps ~ 1.5M bps.

Accordingly, the transcoder 212 can change various contents in a format unsuitable for streaming to a format suitable for streaming. As a result, the present embodiment can implement a streaming service for content streaming or content preview in response to a request from a client have.

3, the content service server 11 displays the uploaded content from the client 30 on a web page providing a search list of the web site or on a specific web page provided for content preview or content sharing, Displays an index for content preview and content sharing next to the content list. The content sharing index can be provided in various forms such as general icons and check boxes. In this process, the low-resolution content is preferentially transcoded through the priority granting algorithm of the transcoding manager 211 and provided to the content preview so as to advance the preview time of the content after the upload, or the metadata of the content or the client 30 The priority of the transcoding can be given or the priority can be lowered.

For example, the content service server 11 activates and displays an icon next to the content list when the first content is preferentially transcoded through the transcoding unit 21 and the second content is transcoded. And displays a progress status when the transcoding is in progress through the coding unit 21, and displays an index for content preview and content sharing in an inactive state.

In addition, the content service server 11 can display content conversion management, streaming information (user, number of plays, play time, etc.), viral information (number of times shared) Here, the content preview index can be implemented as a check box or a button for providing a unique content preview function, and the content share index can be reproduced by streaming through other sites, media e-mail, SNS, etc. without downloading the content Function button. FIG. 3 shows an example, and the present invention is not limited thereto.

4 to 6, the streaming server 22 includes an HTTP media streamer 221, and, in response to a request from the client 40, transmits the advertisement content matched with the metadata of the content to the advertisement management server 23 ), And inserts the advertisement contents provided from the advertisement management server 23 at the key frame level to preview and stream the contents.

Inserting the advertisement content at a key frame level means inserting the advertisement content into a frame set as a key frame among a plurality of frames included in the content, And may be understood to stop the content streaming or content preview and provide the ad content. The key frame is illustrative of the insertion point, and the insertion point can be set by the manufacturer in various ways.

When the client 40 accesses through the location information (URL) of the transcoded contents, the streaming server 22 performs streaming for content streaming or content preview for the content. The streaming server 22 transmits the content on a key frame basis so that the selected content can be reproduced in real time in the player set in the client 40, and the frames are transmitted with the header information so that they can be connected to the subsequent frames. Then, the player of the client 40 receives content at the time of key frame and simultaneously decompresses the content, and reproduces the content by moving picture or voice. Here, the content transmitted for streaming to the client 40 may be either a content storing an original that has been transcoded without transcoding, or a content stored by transcoding a content of an original that is inappropriate for streaming.

And a load balancing unit 25 and a streaming processing unit 26 are further provided between the streaming server 22 and the client 40. [ The load balancing unit 25 controls the plurality of streaming processing units 26 to control the quality of the streaming contents so that the traffic can be dispersed when the content previewing and content streaming services are serviced in response to a request from the client 40 To control the balancing of the load. The streaming processing section 26 is constituted by a plurality of streams and provides content preview and content streaming under the control of the balancing section 25. [

The streaming server 22 serves a content preview and content streaming corresponding to the speed of the Internet network to which the client 40 is connected and performs a progressive downloading method or a HLS HTTP live streaming) protocol. When the client 40 requests the interval data by using the interval transmission function defined in HTTP 1.1, it transmits the frame of the corresponding content. Content preview and content streaming support HLS (HTTP Live Streaming) protocol and HTTPD (HTTP Progressive Download) protocol to configure various devices such as window device, Android device, and iOS device. This technique does not actually segment the content but divides the content into segments and delivers the segments to the player of the client 40.

The streaming server 22 accumulates the actual playback time in a separate player or a browser-embedded player, controls the total cumulative time in the case of the content preview so that it does not exceed the predetermined content preview time, exceeds the set content preview time The content preview function is terminated, and control is performed so that the content preview is no longer performed. At this time, the client 40 can extend the content preview time through the advertisement view. For example, the content service server 11 may display a window corresponding to the advertisement, and configure the client 40 to provide the advertisement URL to the client 40 when the client 40 accesses the window corresponding to the advertisement. At this time, when the advertisement management server 23 has data for determining the characteristics of the client, the content service server 11 may be configured to provide advertisements matching with the client 40 by referring to the client characteristics.

Referring to FIGS. 5 and 6, the client 40 requests a type of file, a start offset, a content length, and the like at the time of a request to download HTTP progressive.

The format of the HTTP content request header in HTML is, as shown in FIG. 5,

(1) HTTP / 1.1 206 Partial content

(2) Content-Type: video / mp4

(3) Content-Range: bytes [start] - [end] / [file size]

(4) Content-Length: Contains [file length].

The HTTP media streamer 221 of the streaming server 22 receives the streaming request of the content from the player of the client 40 and receives the information about the content from the content store 12, And inserts the advertisement contents into the preset insertion point in real time. At this time, the streaming server 22 can adjust the length of the content including the advertisement by increasing the size of the content (File Size).

The streaming server 22 uses an adaptive bitrate streaming method for transmitting different quality contents according to the network environment of each device. When the streaming server 22 receives a continuous request for each section from the player of the client 40, The insertion point of the advertisement content may be randomly set in response to the response of the server corresponding to the request header value of the advertisement content.

Here, the adaptive bit-rate streaming method collectively refers to dynamic streaming by Adobe, HTTP adaptive streaming by Apple, Smooth Streaming by Microsoft, or HTTP-based adaptive streaming DASH standardized by MPEG (Moving Picture Experts Group) It refers to a method of streaming with appropriate quality according to the state. An MPD (Media Presentation Description) file in which contents of various formats composed of MPEG-4 or MPEG-2 TS (Transport Stream) packets are constituted as a certain segment file and address information for accessing the segment file is stored in the client 40 To the player of the player.

The real-time advertisement management server 23 classifies the advertisement contents into categories using the metadata of the uploaded advertisement contents from the client 50, searches for the matching advertisement contents in response to the request of the streaming server 22, And provides the streaming server 22 with one advertisement content. The advertisement content storage 24 stores the advertisement content under the control of the real-time advertisement management server 23.

In response to the request from the streaming server 22, the real-time advertisement management server 23 provides the streaming server 22 with advertisement contents matched with the metadata of the contents, and stores at least one URL, Or more to the streaming server 22. [0050]

The advertisement management server 23 manages time information on the actual product using the metadata of the content, and can provide the advertisement content to the streaming server 22 at the relevant time. The streaming server 22 inserts the advertisement content provided from the advertisement management server 23 at the key frame level of the streaming content and transmits the URL of the metadata and the detailed data page to the link of the HTTP response field Link field or the like to the client 40 in a real-time manner.

The general progressive download is such that the length of the content is sent to the player of the client 40 and the client requests all or part of it to the streaming server (or web server). As a result, the method of embedding the advertisement contents in the middle of contents is difficult to be implemented due to the problem that the length of the contents provided in advance and the length of contents to be downloaded and streamed do not match with the general downloading or streaming method. However, in the key frame level advertisement insertion method of the present invention, the length of the content and the length of the advertisement content to be inserted may be provided as the length of the content. Therefore, unlike normal downloading or streaming methods, it is possible to insert the advertisement content into the content.

In addition, the HTTP media streamer 221 of this embodiment can control the content playback in real time by controlling the content length in real time in a manner that responds to the content length flexibly by the client. At this time, the content length controlled in real time can be transmitted to the client 40 side. The player of the client 40 can check the length of the contents and use the contents by the above method. In addition, the additional advertisement contents are inserted in the middle of the contents and implemented as if the one contents are transmitted. This approach can be likened to a system that sends out streams of various paths by automatically opening and closing multiple faucets (switching) .

The real-time advertisement management server 23 can layer the unit price of the advertisement contents according to the position inserted into the contents. For example, the advertisement content inserted at the beginning or the end of the content can be classified as low price, and the advertisement content inserted into the part where the issue (ISSUE) is included in the content can be classified as high price. This is like high advertising costs in prime-time broadcasting.

The layering of the unit price of the above-mentioned advertisement contents is performed by a billing server (not specifically shown) for billing the service, an interlocking service between the real-time advertisement management server 23 and the content meta-management server (not specifically shown) And therefore, a detailed description thereof will be omitted. When the advertisement content unit price is layered as described above, the streaming server 22 may be configured to insert the advertisement content selectively in correspondence with the weight of each frame of the content. That is, the advertisement content having the higher unit price can be inserted in real time for the section having the higher weight, and the advertisement content having the lower unit price for the lower weight section can be inserted in real time .
