Referring to FIG. 1, the Internet broadcasting apparatus 100 is connected to at least one or more broadcaster terminals 112 and 114 through an Internet network, and is connected to at least one or more viewer terminals 122 and 124 through an Internet network. Here, the broadcaster terminals 112 and 114 and the viewer terminals 122 and 124 are terminals used by the broadcaster 110 and the viewer 120 to access the Internet broadcasting apparatus, respectively, and all types of terminals capable of wired or wireless communication are used. Include. For example, the broadcaster terminals 112 and 114 and the viewer terminals 122 and 124 may be various conventional terminals such as smart phones, tablet PCs, and general computers.

The internet broadcasting apparatus 100 may include at least one or more channels, and may provide a broadcast program of each channel to the viewer 120 through a real-time streaming service. The internet broadcasting apparatus 100 may allocate at least one or more channels to the subscribed broadcaster 110 through a predetermined procedure. As another example, the internet broadcasting apparatus 100 may divide one channel into several time zones and allocate it to at least one broadcaster 110.

The Internet broadcasting apparatus 100 provides broadcast content (eg, live broadcast) received from the broadcaster terminals 112 and 114 to the viewer terminals 122 and 124 through a real-time streaming service, or broadcast content stored locally (eg, , VOD (Video On Demand) service) may be provided at the request of the viewer terminals 122 and 124.

The broadcaster 110 may broadcast his or her own content through a channel (or a specific time period of the channel) assigned through the Internet broadcasting apparatus 100. For example, the broadcaster 110 may provide a real-time live image to the viewer 120 through its own broadcast channel, or may provide previously created content to the viewer 120 through its own broadcast channel. The previously created content may be stored in the broadcaster terminals 112 and 114 or may be stored locally in the Internet broadcasting apparatus 100 for each broadcaster.

The broadcaster 110 may not only synthesize and broadcast a plurality of contents of itself, but also synthesize and provide broadcaster contents and third-party contents in real time. For example, the broadcaster 110 may synthesize and provide third-party content in real time during a live broadcast such as a soccer broadcast or a game broadcast. A method for the broadcaster 110 to synthesize and broadcast third-party content in real time will be described again below in FIG. 2.

The viewer 120 may watch a desired broadcast program connected to the Internet broadcasting apparatus 100. In other words, the Internet broadcasting apparatus 100 may provide a live broadcast or VOD service selected by the viewer 120 to the viewer terminals 122 and 124 through a streaming service.

As another example, the Internet broadcasting apparatus 100 may provide locally stored broadcasting content or real-time streaming content to the external media server 130 that provides social media services such as YouTube or Facebook.

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

Referring to FIG. 2, the Internet broadcasting apparatus 100 may provide a real-time streaming service by synthesizing 280 contents 210 and 220 of a broadcaster 200 and contents 260 and 270 of a third party 250. For example, if the broadcaster 200 selects the content 1 260 of the third party 250 while broadcasting its own content b 220, the Internet broadcasting apparatus 100 The content b 220 and the content 1 260 of the third party 250 may be synthesized 280 and provided to a viewer terminal.

For example, when the broadcaster 200 selects any one of the contents 260 and 270 of a third party during live broadcasting, the Internet broadcasting apparatus 100 displays the third party contents together on one side of the live broadcasting screen and Can be provided as An example of a broadcast screen provided by an internet broadcasting device is shown in FIG. 9.

The broadcaster contents 210 and 220 may be live images or contents previously stored in the broadcaster terminal or the Internet broadcasting apparatus 100. However, in the following embodiments, it is assumed that the broadcaster content 210 and 220 is a live video (ie, live broadcast).

The third- party contents 260 and 270 may be participation contents registered in advance in the internet broadcasting apparatus 100, participation contents registered in real time during broadcasting, or contents received in real time during broadcasting from at least one viewer terminal. Here, the third party 250 may be a viewer or another broadcaster. An example of participating content is shown in FIG. 3, and an example of receiving real-time content from a viewer terminal while broadcasting is shown in FIG. 7.

3 is a diagram illustrating an example of registered content 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 list of broadcast programs broadcast through each channel (or time zone). In addition, the Internet broadcasting apparatus 100 stores and manages the third party's participation content 312, 314, 322, and 324 by mapping them with the respective broadcasting programs 310 and 320.

For example, when a broadcasting program for real-time internet broadcasting for a baseball game is scheduled, a third party may provide various contents related to the baseball game (for example, information about a baseball player, an interview video of a baseball player, etc.). It is possible to register in advance as a participation content of a broadcast program, or register in real time while the broadcast program is being broadcast.

The Internet broadcasting apparatus 100 may provide a list of participating contents so that the broadcaster 300 can select the participating contents 312, 314, 322, and 324 mapped and stored with the broadcasting programs 310 and 320. For example, as shown in FIG. 9, the Internet broadcasting apparatus 100 provides a broadcast screen 900 and a participation content list 950 to a broadcaster terminal. The broadcaster 300 may select a desired participation content through the participation content list 950 during live broadcasting, synthesize it into his or her own broadcasting, and provide it to the viewer. In other words, the broadcaster 300 that relays a baseball game in real time can perform a more abundant baseball broadcast by using various participating contents registered by a third party in relation to the baseball game.

The Internet broadcasting apparatus 100 may locally store the third party's participation content 312,314,322,324. However, in this case, there is a problem in that a large amount of storage space of the Internet broadcasting apparatus 100 is required. Although the present embodiment does not exclude storing the participating content locally, it is possible to store and manage only some information on the participating content as a method to save local storage space and not be subordinate to the broadcasting terminal. A method of storing and managing some information of participating content will be described in FIG. 5.

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

Referring to FIG. 4, the Internet broadcasting apparatus 100 provides a list of broadcast programs broadcast through each channel to a viewer terminal (S400). For example, a viewer may access the Internet broadcasting apparatus 100 using a viewer terminal and inquire or search for a broadcast program. The present embodiment describes the subject registering the participating content as a viewer, but is not limited thereto, and any person who can access the Internet broadcasting apparatus may be used. However, in the following description, for convenience of explanation, it is limited to viewers.

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

The internet broadcasting apparatus 100 may receive the participation content file itself and store it locally, or register location information (eg, URL information) of a remote server in which the participation content is stored. When the participating content is stored in a remote server and only the location information is registered, the Internet broadcasting apparatus 100 may access the remote server based on the location information and read the participating content when it is necessary to play the participating content. In this case, since it takes a predetermined time to read the participating content, playback of the content may be delayed. A method of preventing a delay in playback of participating content stored in a remote server is illustrated in FIGS. 5 and 6.

In another embodiment, when the participating content is stored in the user terminal and identification information of the user terminal (eg, user email, phone number, IP address, MAC address, etc.) is registered, the Internet broadcasting apparatus 100 Communication connection with the user terminal is attempted, and when the communication is connected, participation content stored in the user terminal can be read.

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

5, participation content 550 is stored in the remote server 500 or a user terminal. Participating content 550 quickly reproduces the header data 552 including media-related information (eg, compression codec, playback time, etc.), media data 5540 such as video and audio, and media data at an arbitrary location. It may be composed of index data 556 including location index information for the purpose. The size of the participating content 550 may vary greatly, and may be any one of various types of data provided through the Internet, such as video, text, or audio. For convenience of explanation, the present embodiment will be described on the assumption that the participating content 550 is image data.

Since the broadcaster utilizes third-party content during live broadcasting, a delay of 1 to 2 seconds can be a factor that degrades the quality of the broadcast, so real-time playback of third-party content is important.

For real-time playback, the Internet broadcasting apparatus 100 stores and manages the participating content 550 and the mapped cache data 510 in a local temporary storage space. The cache data 510 may include a part of the front part of the video data required for immediate playback of the participant content (eg, data corresponding to one minute of the first part of the participating content). The Internet broadcasting apparatus 100 may store and manage the location information or access information of the remote server 500 or user terminal in which participation content is stored together with the cache data 510. The Internet broadcasting apparatus 100 can save local storage space since it is not necessary to store the entire participating content locally.

As an example, the cache data 510 may further include header data 512, index data 516, etc. necessary for reproducing some image data included in the cache data along with some image data 514 of the participating content. I can. The type, form, and order of data included in the cache data 510 may be variously modified according to exemplary embodiments.

The internet broadcasting apparatus 100 first plays some of the image data 514 included in the cache data 510 when it is necessary to play the participating content 550. The Internet broadcasting apparatus 100 may access the remote server 500 in which the participation content 550 is stored during playback using the cache data 510 to read all or a necessary part of the participation content 550. For example, if the image data of the first part of the participating content is stored in the cache data, the Internet broadcasting apparatus 100 transmits the image data from the part exceeding 1 minute to the remote server 500 by using index data. Can be received by request.

Since the Internet broadcasting apparatus 100 can play the video included in the cache data 510 during the required time for reading the participation content 550 from the remote server 500, the participation content 550 can be played in real time. For example, when the file of the participating content is a file in the form of'avi' or'mp4', the Internet broadcasting apparatus reads the header 512 and the index 514 of the cache data 510 and writes the contents to the cache data 510. It is possible to read some of the included image data 516 and perform real-time playback immediately without receiving the entire data from the remote server 500. Since image data not included in the cache data can be read from the remote server 500 during playback using the cache data 510, the remote server 500 can be implemented as a general file server or web server as well as a dedicated media streaming server. have.

In one implementation, when the remote server 500 is a general server or a web server, the Internet broadcasting apparatus 100 reads the video data 554 of the participating content 550 from the remote server 500. -Time Communication), FTL (Fast Than Light), SIP (Session Initiation Protocol), or SRT (Secure Reliable Transport). For example, the Internet broadcasting apparatus 100 requests a one-to-one communication connection using WebRTC to the remote server 500, and requests and receives the image data 554 of the participating content 550 corresponding to the cache data 510. can do. The internet broadcasting apparatus 100 may request the image data 554 of the participating content 550 by using a URL address indicating the location where the participating content 550 is stored.

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

Referring to FIG. 6, the internet broadcasting apparatus 100 receives a request for registration of participation content from a viewer terminal (S600). For example, after accessing the Internet broadcasting apparatus 100 through the viewer terminal, the viewer may request registration of the 1a participation content 312 in the first broadcasting program 310 of FIG. 3. The Internet broadcasting apparatus 100 may receive location information of a remote server in which participation content is stored, from a viewer terminal.

The Internet broadcasting apparatus 100 accesses the remote server in which the participation content is registered, receives some data of the beginning of the participation content, and then generates cache data including this (S610). An example of cache data is shown in FIG. 5.

The Internet broadcasting apparatus 100 maps the cache data with a broadcast program and stores it locally (S620). The Internet broadcasting apparatus 100 may identify and display a list of participating contents registered in a broadcasting program through cache data. For example, the Internet broadcasting apparatus 100 may display a list of participating contents in the form of a thumbnail as shown in FIG. 9.

7 is a diagram illustrating an example of a concept of synthesizing content of a viewer terminal according to an embodiment of the present invention.

Referring to FIG. 7, the internet broadcasting apparatus 100 may connect one-to-one communication with at least one viewer terminal 730 while broadcasting broadcaster content 710 to viewers. For example, the Internet broadcasting apparatus 100 may receive a selection of a viewer terminal 730 to be connected to one-to-one communication from a broadcaster. In order to facilitate the selection of the viewer terminal 730, the Internet broadcasting apparatus 100 A list of viewers being viewed can be provided to a broadcaster terminal.

The Internet broadcasting apparatus 100 may provide the content 720 received in real time from the viewer terminal 730 connected to one-to-one communication with the broadcaster content 710 by synthesizing 700. For example, the viewer terminal 730 transmits a real-time live image photographed through a camera to the Internet broadcasting device 100 through one-to-one communication, or transmits the content stored in the viewer terminal 730 to the Internet broadcasting device 100. I can.

Although this embodiment shows one viewer terminal 730, the Internet broadcasting apparatus 100 may connect a plurality of user terminals and one-to-one communication simultaneously or sequentially, and receive content from a plurality of user terminals in real time. .

For example, a broadcaster may conduct an interview with a viewer while broadcasting a baseball. The internet broadcasting apparatus 100 connects the viewer terminal 730 selected by the broadcaster and one-to-one communication, and the viewer terminal 730 receiving the one-to-one communication connection request transmits a live image photographing the viewer to the internet broadcasting apparatus 100. . Then, the Internet broadcasting apparatus 100 displays a baseball game screen on the first screen 910 on the broadcast screen 900 as shown in FIG. 9, displays the broadcaster's live image on the second screen 920, and A live video of a viewer may be displayed on the screen 930. General viewers can watch an interview broadcast between a broadcaster and a specific viewer in real time.

Referring to FIG. 9, the internet broadcasting apparatus generates a broadcasting screen 900 displaying at least one or more contents. The broadcast screen 900 may include a plurality of screens 910, 920, and 930 for displaying a plurality of contents. A plurality of screens 910, 920, and 930 may overlap and be displayed. For example, the second screen 920 and the third screen 930 may be superimposed on one side of the first screen 910. Alternatively, the first to third screens 910, 920, and 930 may not overlap each other and may be displayed by dividing the screen in various ways. The content to be displayed on each screen 910, 920, and 930 can be variously modified according to exemplary embodiments. In addition, the number or arrangement method of the screens 910, 920, and 930 included in the broadcast screen 900 may be variously modified according to exemplary embodiments.

For example, in the case of broadcasting a baseball broadcast, the Internet broadcasting apparatus 100 displays a baseball game screen on the first screen 910, a screen photographing a broadcaster on the second screen 920, and 3 On the screen 930, participation content according to a broadcaster's selection or content received in real time from a viewer terminal may be displayed. Whether to display the third screen 930 may be determined according to a broadcaster's selection. As another example, when playback of the participation content is completed on the third screen 930, the third screen 930 may be automatically excluded from the broadcast screen 900.

As another example, when a broadcaster selects specific participation content from the participation content list 950 during baseball broadcast, the participation content may be displayed on the first screen 910. When the play of the participant content is completed or the broadcaster requests a stop while the participant content is being played, the first screen 910 may display the previous baseball broadcast screen again.

The broadcast screen 900 may further include a chat window 940. Depending on the embodiment, the chat window 940 may be omitted. The broadcaster may select at least one or more users to receive real-time content through one-to-one communication through the chat window 940. When the broadcaster selects at least one user through the chat window 940, the Internet broadcasting apparatus 100 connects a one-to-one communication with the user's terminal and receives real-time content from the user terminal.

The internet broadcasting apparatus 100 may have different screens provided to the viewer terminal and the broadcaster terminal. For example, the Internet broadcasting apparatus 100 provides only the broadcast screen 900 to the viewer terminal, and the participating content list 950 that is previously registered in the broadcast program or registered in real time along with the broadcast screen 900 to the broadcaster terminal. ) Can be provided together.
