You can use the "Keyword Blocking" feature to block access to specific pages within a site.

For example, if you want to block the video page on the Naver site, access that page and identify a keyword in the web address (URL) bar at the top that uniquely identifies the page. In <Figure 2>, the keyword "m_video" seems suitable. Since all web pages containing "m_video" in their URL will be blocked, unexpected pages might also be blocked. To minimize this, you can register the keyword "where=m_video" as shown in <Figure 3> to narrow down the criteria for identifying video pages.

In the same way, if you want to block the image page within the Google site, you can confirm that "tbm=isch" is a suitable block keyword and register it as shown in <Figure 3>. The keyword required to block the video tab searched on Google is "udm=7".
 

※ This guide is an application method for blocking access to specific pages. As shown in the screen below, it cannot block playback if the portal main page provides videos without navigating to a dedicated video page. However, since users must navigate to the "video page" to watch more videos, this method is still effective.



If you wish to set it up so that only study-related sites can be accessed, please refer to this help guide.
