3 is a diagram illustrating an example of a process of providing streaming content according to an embodiment of the present invention. 3 shows a player 310, a proxy 320, and a streaming server 330, respectively. Here, the player 310 and the proxy 320 may be software modules installed and driven in a user's terminal device to play streaming content. In addition, the streaming server 330 may be a software module installed and driven in a server device to provide a streaming service. Here, the software module may correspond to a computer program installed and driven in the computer device 200.

In the present embodiment, the process of providing streaming content is largely a first process 340 for requesting a master playlist, a second process 350 for requesting a media playlist, and playing the streaming content. A third process 360 may be included.

In this case, the first process 340 may include the 1-1 process 341, the 1-2 process 342, the 1-3 process 343 and the 1-4 process 344.

The 1-1 process 341 may be an example of a process in which the player 310 requests a master playlist (for example, master.m3u8 of HTTP Live Streaming (HLS)) to the proxy 320.

The 1-2 process 342 may be an example of a process in which the proxy 320 requests and receives master playlists for N number of streaming contents to the streaming server 330, respectively.

Process 1-343 may be an example of a process in which the proxy 320 concatenates the N master playlists received from the streaming server 330. How to connect master playlists will be described in more detail later.

Steps 1-4 344 may be an example of a process of transferring master playlists to which the proxy 320 is connected to the player 310.

Through this first process 340, the player 310 may acquire one master playlist to which N master playlists for N streaming contents are connected.

In addition, the second process 350 may include a process 2-1 351, a process 2-2 352, a process 2-3 3 and a process 2-4 354.

The 2-1 process 351 may be an example of a process in which the player 310 requests a media playlist (eg, playlist.m3u8 of HLS) to the proxy 320.

The 2-2 process 352 may be an example of a process in which the proxy 320 requests and receives media playlists for N number of streaming contents to the streaming server 330, respectively.

The 2-3rd process 353 may be an example of a process in which the proxy 320 connects the N media playlists received from the streaming server 330. How to connect media playlists will be described in more detail later.

The 2-4 process 354 may be an example of a process of transferring the media playlists to which the proxy 320 is connected to the player 310.

Through this second process 350, the player 310 may acquire one media playlist to which N media playlists for N streaming contents are connected.

In the third process 360, the player 310 sequentially receives streaming data (for example, a ts file of HLS) from the streaming server 330 through the connected media playlist acquired in the second process 350, and N It shows an example of a process of sequentially reproducing two streaming contents.

At this time, the player 310 not only has both a master playlist and a media playlist for each of the N streaming contents to be played, but also stores the N streaming contents as one streaming content through one connected media playlist. Will be recognized as. Accordingly, the player 310 can play N streaming contents without interruption of sound or video simply by sequentially receiving and playing streaming data according to the connected media playlist.

In the embodiment of FIG. 3 above, N master playlists for N streaming contents are connected using a proxy 320 as a software module installed and driven in the user's terminal device, and N number of streaming contents are connected. An embodiment of connecting two media playlists has been described. However, according to an embodiment, the proxy 320 may operate as a software module installed and driven in the streaming server 330. For example, when the player 310 requests a master playlist and a media playlist from the streaming server 330, the proxy 320 implemented at the server side together with the streaming server 330 connects the N master playlists. Accordingly, the connected master playlist may be provided to the player 310, and the connected media playlist may be provided to the player 310 by connecting N media playlists.

In addition, in order to enable multiple images of N streaming contents to be reproduced at the same resolution, the proxy 320 addresses the addresses of media playlists of the same resolution from the N master playlists in step 1-3 (343). URL) can be selected and linked.

4 is a diagram illustrating an example of connecting a master playlist according to an embodiment of the present invention. 4 is a connection by selecting URLs of media playlists having the same resolution 440 of 1920Х1080 or 1080Х1920 from the first master playlist 410, the second master playlist 420, and the third master playlist 430 An example is shown. In other words, one master playlist includes URLs of a plurality of media playlists for each resolution. At this time, the proxy 320 searches for the URLs of the media playlists of the same resolution from each of the N master playlists (for example, N master.m3u8 files in HLS) in step 1-3 (343) one by one. By connecting, one connected master playlist can be created. As such, a small value of resolution may be used as a reference value for searching for the same media playlists. In FIG. 3, only the resolution 440 of 1920×1080 or 1080×1920 has been described, but URLs of media playlists may be linked for each of the same resolution values. In this case, other values except for the intersection of all quality lists in the N master playlists may be removed. In other words, among URLs of media playlists included in the N master playlists, URLs of media playlists that do not have an intersection in resolution may be removed.

5 is a diagram illustrating an example of a connected master playlist according to an embodiment of the present invention. The embodiment of FIG. 5 shows an example of one master playlist 510 to which URLs of media playlists of the same resolution are connected. At this time, in order to facilitate the processing of the media playlist requested by the player 310, the URLs of the media playlists in the master playlist 510 may be simplified using at least some of the resolution values as shown in FIG. I can. For example, the embodiment of FIG. 5 shows an example in which the URL of a media playlist corresponding to the connection of URLs of three media playlists having a resolution of 1920Х1080 or 1080Х1920 is simplified to "1080.m3u8".

To this end, the proxy 320 may store a simplified URL (for example, "1080.m3u8") and actual URLs of media playlists in association with each other. In this case, in the second process 350, when the player 310 requests a media playlist by using a simplified URL by the proxy 320, the proxy 320 is It is possible to request N media playlists to the streaming server 330 using URLs. In this case, it will be easily understood that all of the requested N media playlists have the same resolution.

The process in which the proxy 320 connects the N media playlists in step 2-3 (353) described above is a process in which the proxy 320 connects the N master playlists in step 1-3 (343). It can be similar to In other words, the proxy 320 may generate a connected media playlist by connecting URLs of streaming data (for example, ts files) having the same resolution in the media playlists.

Meanwhile, the image data (for example, a ts file or an mp4 file) includes time information called "presentationTime" at which video or audio is output. At this time, since the streaming content 1 and the streaming content 2, which are not related to each other, are forcibly linked through the master playlist (or manifest file), the "presentationTime" is different from each other, and the player 310 plays the streaming content 1 When completing and then playing the streaming content 2, there is a possibility that a malfunction may occur as the "presentationTime" is not continuous. In order to avoid this, in the connected media playlist, "#EXT-X-DISCONTINUITY" is connected to the media playlist of the streaming content 1 and the streaming content 2 so that the player 310 can detect the transition between streaming contents. A tag part can be added. In the case of MPEG-DASH (Moving Picture Experts Group-Dynamic Adaptive Streaming over HTTP), a change in continuity can be specified using "SegmentTimeline".

In addition, when URLs of streaming data in a single connected media playlist are relative addresses, when transitions between streaming contents occur, the default URL may be incorrectly applied. Therefore, the proxy 320 connects the media playlists to the streaming data. You can change all the URLs of the URL to an absolute path that includes the base URL.

For example, it is assumed that the address of the master playlist of streaming content 1 is as follows.

"http://aa.bb.com/video1/master.m3u8"

In addition, it is assumed that the address of a media playlist having a resolution of 720p in the master playlist is as follows.

"#EXTM3U

…

#EXT-X-STREAM-INF:BANDWIDTH=...,RESOLUTION=1280×720

720p.m3u8

In this case, the player 310 requests a media playlist having a resolution of 720p to the URL below.

"http://aa.bb.com/video1/720p.m3u8"

Here, the "http://aa.bb.com/video1/" part may be the base URL.

Meanwhile, the contents of the '720p.m3u8' file may appear as follows.

#EXTM3U

…

#EXTINF:4,

0001.ts

#EXTINF:4,

0002.ts

…

At this time, the URL for requesting streaming data from the player 310 is as follows.

"http://aa.bb.com/video1/0001.ts"

In this case, it may be assumed that the address of the master playlist of streaming content 2 is as follows.

"http://cc.dd.com/video2/master.m3u8"

Manifest (m3u8) files are redirected from the proxy 320, so they are not relevant, but in the case of streaming data (ts file, fmp4 file, etc.), the player 310 directly streams without going through the proxy 320 for efficiency. In order to request streaming data directly from the server 330, the base URL may be different between images. For example, the base URL of streaming content 1 above is "http://aa.bb.com/video1/", while the base URL of streaming content 2 is "http://cc.dd.com/video2/" to be.

Accordingly, when the proxy 320 creates a connected media playlist and provides it to the player 310, the proxy 320 does not add a relative path such as "0001.ts" or "0002.ts", but "http://path". You can put an absolute path such as "/to/0001.ts" in the connected media playlist. If the full URL for streaming data is included, the default URL can be ignored.

In addition, when N streaming contents are connected and played, the proxy 320 sends the streaming server 330 to the streaming server 330 for each of a request for a master playlist and a request for a media playlist. As N requests and N receptions, and N requests and N receptions for a media playlist occur, the latency increases. To overcome this, a streaming fragment template may be utilized.

6 is a diagram illustrating an example of a process of reproducing streaming content using a streaming fragment template according to an embodiment of the present invention.

The streaming server 330 may pre-generate a streaming fragment template for a specific streaming content. Here, the streaming fragment template may include data including a master playlist and a media playlist of the corresponding streaming content described above.

In this case, when N streaming contents are continuously played, the proxy 320 may request a master playlist for N streaming contents to the streaming server 330 in response to a master playlist request from the player 310. In this case, the streaming server 330 may provide a streaming fragment template for streaming contents in which a streaming fragment template is generated among N streaming contents. In this case, it is assumed that a streaming fragment template is generated for each of the N streaming contents in the streaming server 330.

In this case, the proxy 320 can receive all of the media playlists as well as the master playlist for N streaming contents only by N requests and N receptions from the streaming server 300. Therefore, the proxy 320 needs to separately transmit a request to the streaming server 300 because the proxy 320 only needs to provide the media playlist included in the streaming fragment template to the player 310 according to the media playlist request of the player 310. There is no delay, so the delay can be reduced.

If a streaming fragment template is generated only for some of the N streaming contents, the proxy 320 uses the streaming server 330 only for streaming contents for which no streaming fragment template has been created. Media playlists can be separately requested and received.

7 is a flowchart illustrating an example of a method of reproducing streaming content according to an embodiment of the present invention. The streaming content playback method according to the present embodiment may be performed by the computer device 200 implementing the proxy 320 described above. If the proxy 320 is implemented in the user's terminal device, the computer device 200 may correspond to the user's terminal device, and when the proxy 320 is implemented in the streaming server 330, the computer device ( 200) may be one of computer devices implementing the streaming server 330. In this case, the processor 220 of the computer device 200 may be implemented to execute a control instruction according to a code of an operating system included in the memory 210 or a code of at least one program. Here, the processor 220 may cause the computer device 200 to perform the steps 710 to 760 included in the method of FIG. 7 according to a control command provided by a code stored in the computer device 200. Can be controlled.

In operation 710, the computer device 200 may acquire a plurality of master playlists for a plurality of streaming contents through the streaming server 330 according to a request from the player 310. In the embodiment of FIG. 3, the proxy 320 obtains N master playlists for N streaming contents from the streaming server 330 through the 1-1 process 341 and the 1-2 process 342. An example of the process of doing this has been described. In another embodiment, if a streaming fragment template is used, the computer device 200 may obtain streaming fragment templates for each of a plurality of streaming contents from the streaming server 330. In this case, the computer device 200 may obtain master playlists from streaming fragment templates. For streaming content for which the streaming fragment template is not previously generated, the computer device 200 may directly obtain the master playlist from the streaming server 330.

In step 720, the computer device 200 may generate a connected master playlist by connecting a plurality of master playlists. For example, the computer device 200 may generate a connected master playlist by connecting addresses of media playlists having the same resolution among addresses of media playlists included in a plurality of master playlists. In this case, the computer device 200 may simplify the addresses of media playlists having the same resolution to relative addresses using at least some of the values of the same resolution, and add them to the connected master playlist. Previously, an example of generating a connected master playlist by connecting and simplifying addresses of media playlists having the same resolution has been described through the embodiments of FIGS. 4 and 5.

In step 730, the computer device 200 may provide the connected master playlist to the player 310. In this case, the player 310 may obtain addresses of media playlists for each resolution through the connected master playlist. In this case, the player 310 may be regarded as if it obtained the addresses of media playlists by resolution for one streaming content, but the addresses of each media playlist may correspond to a connection of a plurality of streaming content by resolution. .

In operation 740, the computer device 200 may acquire a plurality of media playlists for a plurality of streaming contents according to a request based on the connected master playlist from the player 310. In this case, in an embodiment not using the streaming fragment template, the computer device 200 requests a plurality of media playlists from the streaming server 330 based on the addresses of the plurality of media playlists, and from the streaming server 330 It is possible to receive a plurality of media playlists. In an embodiment using the streaming fragment template, since the streaming fragment template including the media playlist has already been received in step 710, media play through the streaming fragment template without having to communicate with the streaming server 330 separately. You can get a list. As described above, the computer device 200 may separately receive, from the streaming server 330, only a media playlist of streaming content that is not used because a streaming fragment template is generated in advance among the plurality of streaming content.

In operation 750, the computer device 200 may generate a connected media playlist by connecting a plurality of media playlists. For example, the computer device 200 may generate a connected media playlist by connecting an address of streaming data having the same resolution among the addresses of streaming data included in a plurality of media playlists. In this case, the computer device 200 may change the address of the streaming data having the same resolution to an absolute path including the base URL and add it to the connected media playlist. According to an embodiment, the computer device 200 may generate a connected media playlist by adding a detection tag to a portion where a plurality of media playlists are connected so that the player 310 may detect transitions between streaming contents.

In operation 760, the computer device 200 may provide the connected media playlist to the player 310. In this case, the player 310 may sequentially receive streaming data of a plurality of streaming contents by using the address of the streaming data included in the connected media playlist. In this case, the player 310 can sequentially play a plurality of streaming contents as if receiving one streaming content without having to communicate with the streaming server 330 to receive the master playlist and media playlist for each streaming content. have. Therefore, it is possible to prevent the sound or video from being cut off when transitioning between streaming contents.

As described above, according to the embodiments of the present invention, a plurality of streaming contents may be connected and played like a single streaming contents.

The system or device described above may be implemented as a hardware component or a combination of a hardware component and a software component.
