Problems solved by technology

[0004] However, due to the wide variety of browser page content and types, page elements only contain part of the main information of the page. Even if you search for page elements one by one, you may not be able to find the initial focused element, which will cause a focus error, resulting in no response to input, and the browser page will crash. In some cases, the user can only return to the previous main interface or restart the set-top box, and reload the new page. The user experience is poor.
