Hereinafter, steps S100 to S400 described above in FIG. 3 will be described in more detail.

Prior to step S100, the set-top box 20 may transmit a user signal received from a remote control or the like to the media streaming server 50 (S101). In this case, the user signal may include at least one of a signal for entering the commerce channel and a signal for selecting a personalized broadcast recommendation function after entering the commerce channel.

In step S100, the media streaming server 50 may transmit the set-top ID to the data server 60 and request use history information of the set-top ID. At this time, the usage history information request ( S100 ) may be performed in response to a signal for entering a commerce channel according to the aforementioned user signal or a signal for selecting a personalized broadcast recommendation function after entering the commerce channel.

The step of generating the application screen data (S200) may include steps to be described later. The data server 60 may inquire usage history information corresponding to the set-top ID in response to the set-top ID and the corresponding usage history information request signal received from the media streaming server 50 (S201). At this time, the use history information that is inquired may use the use history information stored in the data server 60 in step S13 described above.

The data server 60 transmits the usage history information corresponding to the set-top ID to the recommendation server 70 (S202), and the recommendation server 70 provides a related product code based on the usage history information received from the data server 60. It is possible to generate recommendation information by selecting (S210).

Specifically, in step S210, the recommendation server 70 may select a related product code related to the selected product code included in the use history information according to a predetermined criterion. At this time, a plurality of related product codes may be selected, and the recommendation server 70 may generate final recommendation information by assigning an output order to the plurality of related product codes according to a predetermined criterion. A predetermined criterion for assigning an order may be, for example, higher in priority as the time at which the user signal is received is recent, or, for example, a product of interest (a favorite product, a favorite product, a broadcast notification product, a stock notification product, etc.) The selected product code may have a higher priority. This will be further described in FIG. 7 to be described later.

Then, in step S210, the recommendation server 70 may generate the recommendation information by receiving at least one of a representative image and detailed information corresponding to the selected product code and the related product code. Depending on the embodiment, the media streaming server 50 receives the representative image and detailed information, and the media streaming server 50 may generate application screen data using at least one of the aforementioned recommendation information, representative image, and detailed information. there is.

The recommendation server 70 may transmit recommendation information generated as described above to the media streaming server 50 (S203). Then, the media streaming server 50 may generate the application screen data corresponding to the set-top ID to include UI for each product corresponding to the recommendation information based on the received recommendation information (S220).

Thereafter, the media streaming server 50 may generate streaming data according to an embodiment of the present invention based on the application screen data (S300). Here, the step S300 will be described with reference to FIG. 5 .

5 is a flowchart for explaining a video streaming method according to another embodiment of the present invention together with an operating subject.

Referring to FIG. 5 , a content delivery server 70 is shown instead of the data server 60 . The same information as described in FIG. 4 may be applied to step S200 including steps S210, S203, and S220 shown at the top of FIG. 5. Generating the streaming data of the present invention (S300) may include the steps described below.

The media streaming server 50 uses video identification information corresponding to the selected product code and the related product code, respectively, to transmit video data corresponding to each of the selected product code and the related product code from the content transmission server 80. It can be received (S310). Specifically, the media streaming server 50 may request video data corresponding to each code from the content transmission server 80 by using the selected product code included in the recommendation information and the image identification information corresponding to the related product code ( S301, S302). Depending on the embodiment, the step of requesting video data corresponding to the video data using the video identification information corresponding to the related product code (S301) may be directly performed by the recommendation server 70 instead of the media streaming server 50. . The media streaming server 50 may receive video data transmitted by the content transmission server 80 in response to the requests of steps S301 and S302 (S310).

Thereafter, the media streaming server 50 may generate streaming data by encoding the application screen data generated in step S200 and the video data received from the content delivery server 80 into one streaming video (S320). .

As described above, the application screen data is data for an application screen to be implemented (eg, displayed) on the screen of the TV 10 . Such application screen data may be, for example, image data. When such application screen data is finally implemented on the screen of the TV 10, it may include information about a play area where video data is reproduced and a user interface area including an added UI for each product. For example, the playback area where video data is reproduced may be the entire screen or a portion of the screen of the TV 10, and the playback area where video data is reproduced and the user interface area may overlap each other. As described above, streaming data may be data generated by encoding video data and application screen data together.

Streaming data may be data for real-time transmission and/or playback of video. Streaming data may be generated at predetermined time intervals. Streaming data may be generated and provided by a predetermined signal generated or received. The predetermined signal may be a signal corresponding to the user signal described in step S100. For example, video data and application screen data may be encoded to be displayed integrally and provided as one streaming data.

According to an embodiment, the media streaming server 50 may receive the first video data and the second video data from the content delivery server 80 . In addition, the media streaming server 50 integrates a video from the received first video data, a video from the received second video data, and a user interface for the first video and the second video on one screen ( It is possible to create streaming data that is displayed as a unit. For example, a plurality of video data may be encoded and generated as one streaming data so as to be integrally displayed in one streaming video. That is, a plurality of video data and application screen data may be encoded together and provided as one streaming data in real time. In this case, the first video and the second video are videos corresponding to different related product codes among the aforementioned related product codes, and the streaming data according to an embodiment of the present invention includes a plurality of video data corresponding to a plurality of related product codes. By encoding and outputting a single streaming video, it is possible to minimize the role and load of the set-top box 20 while easily playing a plurality of videos at once.

Then, referring to FIG. 4 again, the media streaming server 50 transmits the generated streaming data to the set-top box 20 (S400). As described above, the set-top box 20 may receive streaming data from the media streaming server 50 and reproduce the received streaming video on the TV 10 in real time. The set-top box 20 receiving the streaming data may control the streaming video to be displayed immediately upon reception. The set-top box 20 can continuously receive streaming data and control the streaming video to be displayed on the TV 10 . The set-top box 20 may change and display the display time of the streaming video in consideration of the corresponding time of the streaming video.

Hereinafter, with reference to FIG. 5, a step (S500) of the media streaming server 50 regenerating streaming data will be described. The media streaming method according to an embodiment of the present invention may further include regenerating streaming data according to a change signal received from the set-top box 20 (S500).

Step S500 according to an embodiment of the present invention may be a step of encoding and regenerating the application screen data and the video data corresponding to the first change signal into one streaming video (first embodiment).

In one embodiment of the present invention, the set-top box 20 may receive a user's selection input while a streaming video is being reproduced on the TV 10 . For example, the set-top box 20 may receive a signal for a user's selection input from an external input/output device (eg, a remote controller) through an input/output interface of the set-top box 20 . For example, the user's selection input may include clicking a button displayed on the screen, scrolling the screen up and down, and scrolling the screen left and right.

The media streaming server 50 may receive a change signal corresponding to the selection input from the set-top box 20 (S510). For example, the change signal may be a signal generated by the set-top box 20 in response to the aforementioned user's selection input.

In one embodiment of the present invention, the change signal may be an input signal corresponding to at least a part of a streaming video. Also, the change signal may include a scroll signal for streaming video. For example, while a streaming video is being played on the TV 10 , a user's selection input corresponding to at least a part of the streaming video may be received by the set-top box 20 . For example, a user's up and down scroll input may be received in response to a scroll button displayed on a TV screen on which a streaming video is played. In this case, the set-top box 20 may transmit a change signal corresponding to the user's scroll input to the media streaming server 50 .

When receiving the aforementioned first change signal from the set-top box 20, the media streaming server 50 may regenerate streaming data according to the first change signal (S520). Specifically, step S520 may include steps described below. First, the media streaming server 50 may regenerate application screen data corresponding to the first change signal. In addition, the media streaming server 50 may encode the video data received from the content transmission server 80 and the regenerated application screen data into data for one streaming video. Accordingly, the streaming data regenerated by the media streaming server 50 may be regenerated in response to the first change signal received from the set-top box 20 . For example, when a user's up and down scroll input is received in response to a scroll button displayed on the user's TV screen, the media streaming server 50 may regenerate application screen data corresponding to the up and down scroll signal. In addition, the media streaming server 50 may encode the video data and the regenerated application screen data in response to the up and down scroll signal. In this case, the encoded and reproduced streaming data may be data for a moving picture reproduced in real time in a form of scrolling up and down based on the user's TV screen.

Step S500 according to the above-described first embodiment will be described in more detail through an example screen of FIG. 6 to be described later.

Step S500 according to another embodiment of the present invention may be a step in which the media streaming server 50 regenerates the streaming data by updating the recommendation information according to the second change signal received from the set-top box 20 ( 2 examples). That is, this is an embodiment in which use history information including a selected product code of a set-top ID corresponding to the corresponding signal is updated according to the second change signal. Accordingly, recommendation information including a selected product code and/or related product code may also be updated.

Regenerating the streaming data according to the second change signal (S500) includes encoding and regenerating the application screen data corresponding to the updated recommendation information and the video data corresponding to the updated recommendation information into one streaming video. can be

The media streaming server 50 may receive a second change signal related to a specific content selection signal for at least a portion of the streaming video from the set-top box 20 (S510). For example, the second change signal may be a signal corresponding to the specific content selection signal of step S11 described above with reference to FIG. 4 .

When receiving the aforementioned second change signal from the set-top box 20, the media streaming server 50 may regenerate streaming data according to the second change signal (S520). Specifically, step S520 according to the second embodiment may be performed by steps described below, which may correspond to steps corresponding to steps S10 and S100 to S300 described above in FIG. 4 and step S300 described above in FIG. 5 Therefore, the explanation is brief here.

First, the data server 60 may update and store usage history information of a corresponding set-top ID according to the second change signal from the media streaming server 50 . The recommendation server 70 may also update recommendation information based on updated use history information. Then, the media streaming server 50 may regenerate application screen data according to the updated recommendation information. In addition, the media streaming server 50 may encode the video data received from the content transmission server 80 and the regenerated application screen data into data for one streaming video. Accordingly, the streaming data regenerated by the media streaming server 50 may be regenerated in response to the second change signal received from the set-top box 20 .

According to step S500 according to the second embodiment described above, personalized broadcasting recommendation content may be provided by reflecting the user's usage history for the commerce channel in real time. Step S500 according to the above-described second embodiment will be described in more detail through an example screen of FIG. 7 to be described later.

In the above, the embodiment in which the first change signal and the second change signal are received has been described as a separate embodiment, but the two change signals are received at the same time, so that the first and second embodiments can be applied sequentially and/or simultaneously. Of course it can.

6 is an exemplary screen 60 output to a user terminal, for example, a TV 10 according to a video streaming method according to an embodiment of the present invention. Specifically, FIG. 6 is an exemplary view of a TV screen implemented in the TV 10 by transferring the streaming data generated by the media streaming server 50 to the set-top box 20 according to an embodiment of the present invention.

Referring to FIG. 6 , on the TV screen 60, application screen data and video data are encoded as data for a streaming video that is integrally displayed on one screen, so that one streaming video can be played in real time. For example, an application screen ap displaying application screen data may be implemented on the TV screen 60 . The application screen ap means all areas except for the video area V1 where a video (broadcasting video) described later is played, and may include various user interface areas A1, A2, and A3. For example, area A1 may be an area to which the user signal described in step S101 of FIG. 4 is input. Areas A2 and A3 may be areas displaying recommendation information including a related product code according to an embodiment of the present invention.

The application screen (ap) may include UIs (S1, S2, S3, ...) for each product corresponding to the product code. Product-specific UIs (S1, S2, S3, ...) are managed and generated using the media streaming server 50, data server 60, and/or recommendation server 70, related product codes, and recommendation information. It may correspond to application screen data generated based thereon.

The TV screen 60 may also include a video area V1. The video area V1 is an area where a video corresponding to each product code of each product UI (S1, S2, S3, ...) is played, and the video can be received from the content transmission server 80 as described above. there is. In the video area V1, when a user selection signal for the UI S1 for each product is received, for example, when a focusing signal is received by a remote control, the video corresponding to the product code of the corresponding UI S1 for each product is enlarged. It may be a region to be reproduced. When the focusing signal is changed for other product-specific UIs (S2, S3, ...), a video corresponding to the product code of the changed product-specific UI can be enlarged and reproduced in the video area V1.

A plurality of product-specific UIs (S1, S2, S3, ...) and/or a plurality of video data implemented in the video area (V1) and application screen data are encoded into one streaming video and displayed on the entire screen of the TV screen (S1). can be played in real time.

In addition, when a change signal by the user's up and down scroll input sc shown in FIG. 6 is received, the application screen ap may be implemented in a form of up and down scrolling. For example, the user's up and down scroll input (sc) may be a button implemented on the TV screen 60, but the present invention is not limited thereto, and the user's up and down scroll input (sc) is not implemented on the TV screen 60. It can be received by the set-top box 20 by a remote control input or the like.

In addition, a plurality of product-specific UIs (S1, S2, S3, ...) may also be implemented in a form of scrolling up and down together with the application screen (ap). At this time, as shown in FIG. 6 , one streaming video implemented in a form of scrolling up and down on the TV screen 60 can be reproduced in real time.

7 is another exemplary screen 70 output to one user terminal, for example, the TV 10 according to the video streaming method according to an embodiment of the present invention. Descriptions of overlapping contents with those of FIG. 6 are omitted or simplified.

Referring to FIG. 7 , an application screen ap displaying application screen data may be implemented on the TV screen 70 . The application screen ap may include various user interface areas A4, A5, and A6. In particular, the TV screen 70 shown in FIG. 7 shows an example of 'usage history information' that is the basis for generating application screen data according to an embodiment of the present invention.

For example, area A4 is a product area of interest to the user, which is used history information for each set-top ID stored by the data server 60. The number of recently watched broadcasts, desired products, favorite products, broadcast notification products, stock notification products, etc. etc. can be indicated. Product codes stored in the data server 60 to be displayed in the A4 area may be assigned a high priority when selecting the above-mentioned related product codes. Area A5 is a recently viewed broadcasting area, and may include a plurality of product-specific UIs (S4, S5, S6, ...) as described above with reference to FIG. 6 . A video corresponding to a product code of a corresponding UI for each product may be played in the plurality of product-specific UIs (S4, S5, S6, ...), and the corresponding video may be received from the content delivery server 80. Area A6 is a search area created based on a user's search signal. Similar to area A4, product codes stored in the data server 60 to be displayed in area A6 can be assigned a high priority when selecting the above-mentioned related product code. there is.

Likewise, the TV screen 70 shown in FIG. 7 also has a plurality of video data implemented in a plurality of product-specific UIs (S4, S5, S6, ...) and application screen data encoded into one streaming video, and the TV screen 70 ) can be played in real time on the entire screen.

According to the present invention, the streaming data generated by the media streaming server can be reproduced in real time by implementing the movement of the application according to the user's selection input as a streaming video. In addition, since the streaming video is created in the media streaming server and played on the TV through the set-top box, there is no limit to the expression of the application screen and various forms of expression are possible.

In addition, according to the present invention, a streaming video generated in a media streaming server can be directly played on a TV screen from a set-top box without the need to separately obtain and play the video from the set-top box, and a plurality of videos and applications can be combined into one streaming video. It is played on the TV screen and has the effect of improving the convenience of video playback and screen configuration.

In the existing method of operating a media cloud server through a set-top box, there was a limit to changing the user interface. For example, in the conventional method, since the set-top box receives a preset image and one video data reproduced in a preset play area and plays them on the TV screen, the set-top box cannot freely change the user interface.

However, in the video streaming system according to the present invention, since the media streaming server generates streaming data that integrally displays a video and a user interface for the video on one screen, the user interface can be freely changed. In addition, in the video streaming system according to the present invention, a streaming video that simultaneously displays two or more videos on one screen can be output, and the area where two or more videos are played can also be freely changed.

In addition, according to embodiments of the present invention, a personalized broadcast recommendation service is provided based on usage history information such as a user's viewing history, purchase history, search history, etc. for each set-top ID, but by reflecting the usage history information in real time, By generating one streaming data, it is possible to effectively and quickly deliver contents to users.
