FIG. 2 is a diagram illustrating an example of content synthesizing concept according to an embodiment of the present invention.

Referring to FIG. 2, the Internet broadcasting device 100 can combine (280) the contents 210, 220 of the broadcaster 200 and the contents 260, 270 of the third party 250 to provide a real-time streaming service. For example, if the broadcaster 200 selects the content 1 260 of the third party 250 while broadcasting his own content b220, the Internet broadcasting apparatus 100 selects the content b220 of the broadcaster 200 and the third party 250. Content 1 260 can be synthesized 280 and provided to the viewer terminal.

For example, if the broadcaster 200 selects one of the third party contents 260 and 270 during the live broadcast, the Internet broadcasting apparatus 100 displays the third party contents together on one side of the live broadcast screen. can be displayed and provided to the user terminal. An example of a broadcast screen provided by the Internet broadcast device is shown in FIG.

The broadcaster contents 210 and 220 are also live images and contents stored in the broadcaster terminal or the Internet broadcasting device 100 in advance. However, in the following embodiments, it is assumed that the broadcaster contents 210 and 220 are live images (that is, live broadcasting).

The third-party contents 260 and 270 are participating contents registered in advance in the Internet broadcasting device 100, participating contents registered in real time during broadcasting, or contents received in real time from at least one or more viewer terminals during broadcasting. But also. Here, the third party 250 is both a viewer and another broadcaster. An example of the participation content is shown in FIG. 3, and an example of receiving real-time content from the viewer terminal during broadcasting is shown in FIG.

FIG. 3 is a diagram illustrating an example of participation content registered for each broadcast program according to an embodiment of the present invention.

Referring to FIG. 3, the Internet broadcasting apparatus 100 stores and manages a broadcasting program list broadcasted through each channel (or time period). Also, the Internet broadcasting apparatus 100 maps third party participation contents 312 , 314 , 322 , 324 with each broadcasting program 310 , 320 and stores and manages them.

For example, when a broadcast program related to real-time Internet broadcasting related to a baseball game is scheduled, a third party may broadcast various contents related to the baseball game (for example, information related to baseball players, interview videos of baseball players, etc.), It can be registered in advance as participating content of the broadcast program, or can be registered in real time during the broadcast of the broadcast program.

The Internet broadcasting apparatus 100 can provide a participating content list so that the broadcaster 300 can select the participating content 312, 314, 322, 324 mapped and stored with the broadcasting programs 310, 320. FIG. For example, as shown in FIG. 9, the Internet broadcasting apparatus 100 provides a broadcast screen 900 and a participating content list 950 to the broadcaster terminal. During the live broadcast, the broadcaster 300 can select desired participating content through the participating content list 950, synthesize it into his broadcast, and present it to the viewers. In other words, the broadcaster 300, who relays the baseball game in real time, is involved in the baseball game and utilizes various participation contents registered by third parties, and can broadcast richer and richer baseball games.

The Internet broadcaster 100 can store third party participating content 312, 314, 322, 324 locally. However, in this case, there is a problem that a large amount of storage space is required for the Internet broadcasting apparatus 100 . Although this embodiment does not exclude storing the participating content locally, as a method for saving the local storage space and not depending on the broadcasting terminal, a method related to the participating content is provided. Only part information can be saved and managed. A method for storing and managing the partial information of the participating content will be described with reference to FIG.

FIG. 4 is a diagram illustrating an example of a method of registering participating content according to an embodiment of the present invention.

Referring to FIG. 4, the Internet broadcasting apparatus 100 provides the viewer terminal with a list of broadcasting programs to be broadcasted through each channel (S400). For example, a viewer can use a viewer terminal to connect to the Internet broadcasting device 100 and inquire or search for broadcast programs. In the present embodiment, the subject who registers the participation content is described as the viewer, but it is not necessarily limited to that, and any person who can connect to the Internet broadcasting device can do so. . However, in the following, for convenience of explanation, the explanation will be limited to the viewer.

The Internet broadcasting apparatus 100 selects a broadcast program for registering participating content from the viewer terminal (S410), and receives a request for registering participating content (S420). The participating content may be content stored on a remote server or even content stored on a user terminal.

The Internet broadcasting device 100 receives and locally stores the participating content file itself, or can be registered with location information (eg, URL information) of a remote server where the participating content is stored. If the participating content is stored in a remote server and only the location information of the participating content is registered, the Internet broadcasting apparatus 100 connects to the remote server based on the location information when the participating content needs to be played back. can be read. In this case, it takes a predetermined time to read the participating content, so content playback may be delayed. A method for preventing playback delay of participating content stored on a remote server is illustrated in FIGS. 5 and 6. FIG.

As another embodiment, if the participation content is stored in the user terminal and the identification information of the user terminal (eg, user e-mail, telephone number, IP address, MAC address, etc.) is registered, the Internet broadcasting apparatus 100 tries to establish a communication connection with the user terminal, and if the communication is established, it can read the participating content stored in the user terminal.

FIG. 5 is a diagram illustrating an example of a concept of locally storing a part of participating content in an Internet broadcasting device according to an embodiment of the present invention.

Referring to FIG. 5, the participating content 550 is stored in the remote server 500 or the user terminal. Participating content 550 includes header data 552 including media-related information (e.g., compression codec, playback time, etc.), media data 5540 such as video and audio, and location index information for quickly playing media data at any position. It is also configured by index data 556 including The size of the participating content 550 is very diverse and may be any one of various types of data provided through the Internet, such as video, text, or audio. In the present embodiment, for convenience of explanation, it is assumed that the participating content 550 is video data.

Since the third-party content is used during the broadcaster's live broadcast, even a time delay of 1 to 2 seconds can degrade the quality of the broadcast, so real-time playback of the third-party content is important. is.

For real-time playback, the Internet broadcasting apparatus 100 stores and manages the cache data 510 mapped with the participating content 550 in a local temporary storage space. Cache data 510 also includes a portion of the front portion of the video data necessary for immediate playback of the participating content (eg, data corresponding to one minute of the front portion of the participating content). Along with the cache data 510, the Internet broadcasting apparatus 100 can store and manage the location information or connection information of the remote server 500 where the participating content is stored, or the user terminal. Since the Internet broadcasting device 100 does not have to store the entire participating content locally, the local storage space can be saved.

In one embodiment, the cache data 510 may further include header data 512, index data 516, etc. necessary for reproducing the partial video data included in the cache data, along with the partial video data 514 of the participating content. . The type, format, order, etc. of data included in the cache data 510 may vary according to embodiments.

If the Internet broadcasting apparatus 100 needs to reproduce the participation content 550 , it first reproduces the partial video data 514 included in the cache data 510 . The Internet broadcasting device 100 can connect to the remote server 500 where the participating content 550 is stored and read the entire participating content 550 or a necessary part during playback using the cache data 510 . For example, if the cache data stores video data for the first minute of the participating content, the Internet broadcasting device 100 uses index data or the like to transfer the video data from the portion exceeding the one minute portion to the remote server 500. can be requested and received from

Since the Internet broadcasting apparatus 100 can reproduce the video included in the cache data 510 for the required time for reading the participation content 550 from the remote server 500, real-time reproduction of the participation content 550 is possible. For example, if the participating content file is in the 'avi' format or the 'mp4' format, the Internet broadcasting device reads the header 512 and the index 514 of the cache data 510, Data 516 can be read and played in real time immediately without receiving the entire data from remote server 500 . Video data not included in the cache data can be read from the remote server 500 during playback using the cache data 510. Therefore, the remote server 500 can be a general file server or web server as well as a dedicated media streaming server. is also embodied by

As an example, if the remote server 500 is a general server or a web server, the Internet broadcasting device 100 uses WebRTC (web real-time communication) to read the video data 554 of the participating content 550 from the remote server 500 . ), fast than light (FTL), session initiation protocol (SIP), or secure reliable transport (SRT) using an ultra-low delay real-time transmission protocol of 1 second or less. For example, the Internet broadcasting apparatus 100 may request the remote server 500 for one-to-one communication connection using WebRTC, and may request and receive the video data 554 of the participating content 550 corresponding to the cache data 510 . The Internet broadcasting apparatus 100 can request the video data 554 of the participating content 550 using the URL address indicating the location where the participating content 550 is stored.

FIG. 6 is a diagram illustrating an example of a method for locally storing cache data, according to an embodiment of the present invention.
