For example, the capture prevention information 50 may be a viewer ID, and the mixing of the capture prevention information 50 may be watermarking the viewer ID on the content. If the capture event according to an embodiment of the present invention is not detected, the watermarked viewer ID will be displayed on the broadcast screen with the content with a transparency less than a preset level. On the other hand, when a capture event according to an embodiment of the present invention is detected, the watermarked viewer ID will be displayed as a broadcast screen with content with a transparency greater than a preset level. Therefore, it is possible to prevent the content from being captured illegally. In this regard, the content broadcasting device 100 may load the capture prevention information 50 stored in the memory 140 and mix the loaded capture prevention information 50 and the collected content. In the above-described operation, the content broadcasting apparatus 100 may generate the mixed content by mixing the capture prevention information 50 in real time with respect to the content (eg, the camera 130 image) acquired in real time. In the above-described operation, the content broadcasting device 100 may control the capture prevention information 50 to be displayed at a designated location of the content. Alternatively, the content broadcasting device 100 may control the capture prevention information 50 to be displayed at an arbitrary location of the content. Depending on the characteristics of the content acquired in real time, the content broadcasting device 100 may randomly change and display the location where the capture prevention information 50 is displayed in a predetermined time unit to be mixed. The content broadcasting device 100 may process the capture prevention information 50 to have a specified transparency. In addition, the content broadcasting device 100 may adjust the transparency in correspondence with the video characteristics of the corresponding content. For example, the content broadcasting apparatus 100 may control to increase or decrease the transparency according to at least one of brightness, contrast, and color of an image of the content.

Next, in step 409, the content broadcasting apparatus 100 may perform broadcast processing of the mixed content. For example, the content broadcasting device 100 may upload the mixed content to the content providing server device 300 and receive an online broadcasting channel associated with the content. The content broadcasting device 100 may obtain device information of the content reproduction device 400 connected to the corresponding channel. The content broadcasting device 100 may generate adjusted content having different resolutions or sizes according to device information, and control the content to be transmitted to the corresponding content playback device 400 through the content providing server device 300.
